EUGLOSSA EVANI ID 



limb in four parts"; petals four, inserted into the throat 

 of the calyx ; stamens springing from a ring on the 

 calyx : filaments awl-shaped, erect ; anthers round- 

 ish ; style simple, filiform ; stigma obtuse ; germen 

 two-celled ; berry one-celled. ^Several species of the 

 Eugenia yield fine fragrant fruit, and are plentiful in 

 the market of Malacca and other towns in the eastern 

 islands of India. 



EUGLOSSA (Latreille). A genus of beautiful 

 bees inhabiting South America, having the parts of 

 the mouth elongated into a proboscis, as long or 

 longer than the body, the labial palpi are terminated 

 in a point composed of the two last joints. Their 

 economy is not known. Some of them are, however, 

 supposed to be parasitic upon other bees. 



EULOPHIA (R. Brown). A genus belonging 

 to the OrchidecE, chiefly natives of Africa. There are 

 eight species in the books, and have been all intro* 

 duced into our collections within these last ten or 

 twelve years. Two fine species from Sierra Leone 

 require to be kept in the stove ; the others do well 

 in the greenhouse. 



EULOPHUS (Geoffroy). A genus of minute 

 but highly beautiful hymenopterous insects, belonging 

 to the section Tcrcbrantin, family Pupivora, Latreille, 

 and family Chalicidce, distinguished by having the 

 tarsi composed of only four joints, and the antennae of 

 not more than eight or nine. In the males these 

 organs are beautifully branched, the branches being 

 long, and arising from the upper side. The Ichneu- 

 mon peclinicornis, Linnaeus, is the type. It is of a 

 black colour and very minute. Geoffroy observed 

 the economy of one of the species, which is parasitic 

 in the body of the caterpillar of some nocturnal moth 

 (Noctua), out of which, when arrived at the full size, 

 numerous larvae of the Eulophus burst forth, arranging 

 themselves upon the leaf in a circle round the insect 

 which they had thus destroyed. Here they assumed 

 the pupa state, and shortly afterwards appeared in 

 the winged form, being of a fine green colour, with 

 the antenna? straw-coloured at the base. Several other 

 species have been observed, whose economy differs 

 somewhat from that of the preceding. 



EUMENES (Fabricius). A genus of solitary 

 wasps ( Vcspidce), remarkable for the very narrow 

 form of the basal segment of the abdomen, which is 

 long and often pear-shaped, the lower lip is divided 

 at its extremity into three lobes, glandular at the tips, 

 the central one being the largest, heart-shaped, and 

 notched at the extremity. The females, unlike those 

 of the common gregarious wasp, separately construct 

 their nests upon the twigs of plants, especially upon 

 heaths with a very fine kind of earth. The nest is 

 spherical, and, according to Geoffroy, filled with 

 honey. There are numerous exotic species, but one 

 only has hitherto been found in this country, namely, 

 the Eumcnes atricornis, which is met with in Hamp- 

 shire on heathy situations. 



EUMOLPUS (Kugellan). A genus of coleo- 

 pterous insects, belonging to the section Tetramera, 

 and family C/irysomclid&ydiffenng from Cryptocephalus, 

 to which they are very nearly allied by having the 

 terminal joints at the antennae dilated ; the body is 

 very convex, and the maxillary palpi thickened at the 

 tips. The majority of these insects inhabit tropical 

 countries ; they are for the most part exceedingly 

 brilliant in their colours. We have already, in our 

 article upon the ChrysomelidcE, given an account of 

 the ravages committed by a small species of this 



447 



genus upon the vines in the wine countries of Europe. 

 Vide ante, page 41. 



EUOMPHALE. A fossil genus of shells esta- 

 blished by Sowerby, and forming one species of the 

 present arrangement of the genus Solarium. 



EUONYMUS (Tournefort). Is the common 

 spindle-tree of our hedges. There are sixteen exotic 

 species from different parts of the world, alreadv 

 described ; some of the latest from Nepal. 



EUPATORIUM (Linnanis). An extensive genus 

 of herbs, shrubs, and under-shrubs, mostly natives of 

 America. This genus gives a title to a sub-order in 

 the extensive natural order Composifcp. 



EUPHORIA (Commeline). A genus of Chinese 

 and East Indian cultivated fruit trees; one of which 

 is called by the Chinese Litchce, and another Longan ; 

 both common in the markets of Canton. Class and 

 order Octandria JMonogynia, and natural order Sapin- 

 deaccaB. These fruits are sweet with a sub-acid 

 flavour, and when the outer shell is dried, the pulp 

 surrounding the seed shrinks from the shell and 

 remains good for several months. In the dried state 

 they are brought to this and other countries of Europe. 



EUPHRASIA (Linnaeus). Euphrasia offic'malis 

 is the eyebright of British botany ; a common annual 

 frequent on dry pastures. Class and order Didyna- 

 mia Angiosperma, and natural order Scrophularina:. 



EUPLECTUS (Kirby). A genus of coleo- 

 pterous insects, belonging to the minute family Pse+ 

 lapludcE (see BRYAXIS), having the body considerably 

 elongated and depressed, the antenna; with the two 

 basal joints thickened, and the maxillary palpi conical 

 at the tips. The species are found in deep situations, 

 on moss, &c., or flying in clear sunshine. There are 

 about a dozen species, including the type Pselaphus 

 nanus of Riechenbach. 



EURYALE (Salisbury). A curious aquatic plant, 

 a native of India, very much resembling the water- 

 lily in the shape of the leaves, their manner of float- 

 ing on the surface of the water, and in the mode of 

 flowering ; but the leaves are remarkably rough with 

 tubercles and spines, and the flowers are by no means 

 so conspicuous, or so beautiful. Class and order, Poly- 

 andria Monogynia, and natural order Nymphae'iaceee. 

 When cultivated in this country, the seeds are sown 

 in larjj-e tubs of water, and placed in a hotbed. 



EURYCLES (Salisbury), a bulbous genus found 

 at Amboyna, and other places in the East Indies. It 

 is a hexandrious plant, and belongs to the natural 

 order AmarijUidca;. It was described as a Pancratium 

 by Linnaeus and Ker, and a Ciinum by Roxburgh. 



EUTAXIA(R. Brown). A genus of two species of 

 evergreen shrubs, natives of New Holland. The flow- 

 ers are decandnous, and belong to the natural order 

 Leguminoscs. Those plants require pruning or top- 

 ping when young, to make them bushy, and are easily 

 increased by cuttings. 



EUTERPE (Gaertner.) A genus of palms, 

 natives of the African islands, of Madagascar, &c. 

 and South America. They were united to the Areca 

 family by Jacquin and others. 



EVANIID^E. A family of hymenopterous insects 

 belonging to the section Terebrantia, and sub-family 

 Pupivora, having the antenna? composed of thirteen 

 or fourteen joints, the mandibles toothed, the wings 

 veined, and the abdomen attached to the thorax close 

 to the scutellum. The ovipositor is either not ex- 

 serted, as in Evania and Pelecinus, or very long, as 

 in Fcenus, Aulactis, and Megalyra.
