group is established by Illiger as the genus Stenopterus, it follows 

 that Linnaeus's name must be restored, and Fabricius's Molorchus 

 must fall. 



Of this remarkable genus there are only two British species 

 known. 



1. N. minor Linn. Faun. Suec. no. 837- — Curt. Brit. Ent.pl. 11. — dimidiata JFai. 



Black, sparingly clothed with fine long hairs : palpi ochreous ; antennae 

 ferruginous, dark towards the apex, 3rd and 4th joints as long as the fol- 

 lowing ; head coarsely punctured and vermiculated : thorax suborbicular- 

 quadrate, thickly and coarsely punctured, somewhat shagreened, the hairs 

 whitish, with a long shining elevated mark down each side the back, di- 

 lated anteriorly, and a similar spot between them at the base ; scutellum 

 with white depressed hairs : elytra naked, very glossy, sparingly punc- 

 tured, castaneous, darkest at the tips across which there is a depressed 

 line with a green tinge, violaceous at the base ; on the disk of each is an 

 elevated, pale yellow and oblique stripe, approaching behind ; wings fus- 

 cous iridescent : abdomen with the segments on each side beneath edged 

 with silvery hairs : legs hairy, castaneous, apex of thighs subpiceous ; 

 tarsi paler. 



The smaller figure in the plate shows the natural size of a speci- 

 men that was taken in June 1823, upon the blossoms of a tree in 

 the beautiful and ornamental grounds of Mrs. Walker at Arno's 

 Grove, near Southgate, and communicated to me by Edwin Wal- 

 ker, Esq., to whose liberality I am indebted for several rare and 

 interesting insects. It has since been found by his brother upon 

 grass under trees : it has also been taken in the adjoining county 

 of Flertfordshire, and was captured many years since by Mr. Gries- 

 bach near Windsor. 



2. N. Umbellatarum Linn. Sysf. Nat. 2. 641. 3. — Oliv. v. 4. no. 74. tab. 1./. 3. 



Length 21 to 3^ lines. Black, sparingly clothed with fine long upright 

 hairs, trophi ochreous ; antennse castaneous, 3rd and 4th joints not longer 

 than the 1st : head and thorax coarsely punctured, the former with a po- 

 lished line at the base, the latter with a tubercle on each side below the 

 middle, and 3 polished spots on the disc sometimes elongated, forming an 

 inverted triangle : elytra rather sparingly punctured, the hairs short, cas- 

 taneous, with an ochreous space round the scutellum and extending to the 

 middle ; breast and abdomen piceous inclining to chestnut : legs dark cas- 

 taneous, tarsi paler. 



This species was formerly not uncommon in the lane leading to 

 Darent Wood, Kent, upon the dead branches of old trees, in which 

 probably the specimens were bred ; and several were found by my- 

 self, in a hot day in June, upon an umbelliferous plant in a garden 

 adjoining the same lane. It has also been seen in Coomb Wood, 

 Surrey ; and Mr. J. Sparshall captured it at Wrabness in Essex. 



The Plant accompanying the insect is jEthusa Cynaphm (Fools' 

 Parsley).
