Mr. CO. Waterhouse on new Species of Coleoptera. 213 



XVIII. — Neio Species of Coleoptera belonging to the Families 

 Lycidge, Zophosinre, Lepturinse, and G-laucitinae. By 

 Charles O. Waterhouse. 



The species here described are in the British-Museum collec- 

 tion, with the exception of -the Nosoderma, which is in Colonel 

 Shelley's possession. It is with great reluctance that I place 

 this last insect from East Africa in the genus Nosoderma, 

 which has hitherto been considered to be properly American. 

 I do not, however, find sufficient characters upon which to 

 found a new genus. 



Lyeidse. 



Lyropanis biguttatus 7 n. sp. 



Fulvo-ochraceus, opacus, dense brevissime pilosus ; corpore subtus 

 antennarumque articulis apicalibus nigris, singulis elytris gutta 

 fusca notatis. 



Long. 5 1 lin. 



Differs from L.fallax, Walker (Ann. & Mag. Nat. Hist. 

 1858, ii. p. 281 ; Waterhouse, Illustr. Typ. Coleopt. Brit. 

 Mus., pt. i. p. 78, pi. xviii. fig. 4), in being of a more sandy 

 yellow, and in having the legs and the antennae (except the 

 two or three apical joints) also sandy yellow. Each elytron, 

 moreover, instead of having an apical black band, has only a 

 small dusky spot at some distance from the apex. 



Hab. Malabar. 



The genus Lyropceus was proposed by myself (Trans. Ent. 

 Soc. 1878, p. 105) for Lycus fallax, Walker. The present 

 species, although differing chiefly in colour, is, I think, un- 

 doubtedly to be considered distinct. The sides of the thorax 

 are a little sinuous, which makes the posterior angles appear 

 more diverging ; but it is not safe to give this as a specific 

 character without having a series of specimens. Mr. F. Moore 

 has kindly presented the British Museum with one of the 

 specimens from his collection. 



Ditoneces obscurus, n. sp. 



Fusco-niger; thoracis limbo elytrisque ferrugineis, his fortiter punc- 



tato-striatis. $ . 

 Long. 4 lin. 



Relatively rather broader than any described species. It 

 most nearly approaches D. pubicornis, Walker (see Water- 

 house, Illustr. Typ. Coleopt. Brit. Mus., pt. i. p. 32, pi. vii. 

 fig. 9), but is rather broader, and the colour of the margins
