COLEOPTERA. 463 



Phaleria, Lat. -Uloma, Phaleria. Dej. 



The last joint of the maxillary palpi larger and securiform, or 

 like a reversed triangle; anterior tibiae wider, dilated in the manner 

 of a reversed triangle, and frequently dentated, or furnished with 

 small spines on one of its sides(l). In 



Diaperis, Geoff. Fab. 



Or Diaperis properly so called, the maxillary palpi terminate in an 

 almost cylindrical joint, hardly thicker than the penultimate; and 

 the anterior tibiae, hardly or not at all wider than the following ones, 

 are narrow, almost linear, and slightly dilated at the extremity. 



Among those species where the body is ovoid and convex, the 

 thorax is lobate posteriorly, and the antennae are thick and 

 almost entirely perfoliate, comes the D. boleti; Chrysomela boleti, 

 L. , Oliv., Col., Ill, 55, 1, whose body is about three lines long, 

 of a glossy black, with three fulvous-yellow, transverse and den- 

 tated bands on the elytra. In the fungi of trees. 



Another more elongated species, placed among the Ips by 

 Fabricius hasmorrhoidalis forms the genus Neomida of Zieg- 

 ler. The head of the male is armed with two horns(2). 



(1) Some by their elongated form approach Tenebrio. The intermediate joints 

 of the antennae are almost obconical, and the four last compose a perfoliate club. 

 The head of the males is horned. M. Dalmar has figured a species of this divi- 

 sion Phaleria furcif era, Analect. Entom., IV. M. Fischer Entomog. Imp. Russ., 

 II, xxii, 3 has fig-ured another. The Trogositae taurus, quadricornis, vacca of 

 Fabricius belong to this division. 



Others have the body oval and depressed; and the antennae very perfoliate 

 such are the Tenebriones culinaris, retusus, chrysomelinus, impressus, nitidulus 

 of that author. 



The species of these two divisions form the genus Uloma, Meg. and Dej. Those, 

 in which the body is shorter and more rounded, in the form of a short ellipsis, or 

 even hemispherical, and in which the six or seven last joints of the antenna are 

 almost globular, constitute the Phaleria, Dej. The Tenebrio cadaverinus, Fab., is 

 of this number. 



A species bicolor from the Cape of Good Hope, belonging to this division, is 

 distinguished from the preceding ones by the maxillary palpi, which are termi- 

 nated by a proportionally larger securiform joint, and by its antennae, of which the 

 four last joints are alone globular. 



Another peltoides approaches Peltis and Cossyphus, Fab., in its flattened 

 form. Its antennae are' hardly perfoliate; most of the joints, and even the last, 

 being in the form of a reversed cone. 



(2) The Trogositae cornuta, and maxillosa of Fabricius, on account of the dif- 

 ference in the mandibles presented in the two sexes, might be formed into a sepa-
