ENGIDiE. — ATOMARIA. 69 



Oblong-ovate, slightly convex, glossy-black, with the thorax fuscous, the an- 

 tennae and legs rufo-ferruginous. 



From the preceding this differs in having the thorax fuscous and the apex of 

 the elytra concolorous with the base, and the body somewhat convex. 



Inhabits the metropolitan district, as well as the counties of Suf- 

 folk and Norfolk. 



Sp. 18. dorsalis. Brevis ovata, subconvexa, picea, antennis pedibusque rufo- 



ferrugineis, elytrorum dorso nigro. (Long. corp. 5 lin.) 

 At. dorsalis. Kirby MSS.—Steph. Catal. 85. No. 913. 



Short, ovate, slightly convex, piceous, with the antennae and legs rufo-fer- 

 ruginous ; the base of the elytra on the back black. 



The deep black dorsal patch at the base of the elytra, combined with the short 

 slightly convex form of the insect, and pale pitchy colour, at once distinguish 

 this species from its congeners. 



Inhabits the neighbourhood of London, and the vicinity of 

 Ipswich. 



B. Antennae approximating at the base *. 



Sp. 19. nigrirostris. Oblonga, rufo-picea, capite nigro, antennis pedibusque rufo- 



ferrugineis. (Long. corp. ^ — § lin.) 

 At. nigrirostris. Kirby MSS.—Steph. Catal. 85. No. 915. 



Oblong, depressed, pitchy-red, with the head black, the antenna? and legs rufo- 

 ferruginous. 



This species differs from the following by having the head alone black, and 

 from At, linearis by being less linear, and of a pitchy-red colour. 



Not uncommon in the neighbourhood of the metropolis ; found 

 also in other parts of the country. " Roots of grass, Battersea- 

 fields. 11 — Mr. Ingpen. 



Sp. 20. nigriventris. Oblonga, testacea, thorace abdomineque nigro-fuscis, 



antennis pedibusque fulvis. (Long. corp. \ — § lin.) 

 At. nigriventris. Kirby MSS.—Steph. Catal. 85. No. 916. 



Oblong, slightly depressed, testaceous, with the thorax and abdomen fuscous- 

 black : the antennae and legs fulvous, or rufo-testaceous. 

 The deep fuscous thorax of this species, and testaceous head, distinguish it from 



* Although some of the species of the preceding section have the antennae 

 somewhat approximating at the base, they are, compared with those of this 

 section, remote ; the contour of the insects of the two sections is widely dif- 

 ferent : those of the present being more or less linear, and but slightly convex, 

 thereby approaching in form to the Typhaeae.
