274 Mr. G. Lewis on a new Genus of Goleoptera. 



critically, but I think I am riglit in saying that they cannot 

 be separated generically. But, however this may be, the 

 generic name I have employed will associate the species with 

 Japan, as having been first characterized from thence, and 

 the specific name will record the colour of the Japanese 

 insect as well as the colour of the others, for all agree m this 

 last particular. The genus is close to Nemozoma, LatreiUe 

 [Nemosoma, Curtis), and to assist in its recognition I have 

 given a simple outline of it. From Its habits it is_ difficult to 

 obtain, and I have not sacrificed an example for dissection. 



Shoguna, n. gen. 



Mouth-organs externally similar to those of Nemozoma] 

 mandibles robust, dentate within, and bent inwards from their 

 bases ; eyes small, almost circular in outline, partly visible 

 from above ; antennas inserted between the 

 eyes and the bases of the mandibles ; head, 

 including the mandibles, measures the 

 same as the thorax ; epistoma obtusely 

 subfurcate, nearly similar to that 

 figured for N^^onms ohtusiceps (Trans. 

 Ent. Soc. Lond. 1885, p. 335). Antenna; 

 short, 11-joInted, joints 1-2 large, 3-8 

 monlllform, 9-11 transverse to form a 

 club, 11 fitting closely into 10, 9 freer. 

 Thorax long, a little sinuate on the sides ; 

 elytra one fourth longer than the thorax ; 

 the sutural strife are entire and continued 

 round the apices and sides, the other 

 striae are punctate-strlate ; pygidium 

 slightly convex, wholly exposed, and some- 

 what conical in outline when viewed from 

 above; prosternum a little excavated between the coxae; 

 anterior portion of the mesosternum rather convex, smooth 

 and shining ; thighs robust ; feet 5-joInted, basal joint but 

 little visible. 



Shoguna rufo-testacea^ n. sp. 



Angustata, rufo-testacea, nitida, leviter depressa, subparallela, 

 supra minutissime strigosa et disperse elongato-punctata ; 

 fronte utrinque oblique bisulcata ; prothorace elongato, latenbus 

 subsinuato ; elytris stria suturali Integra, l^'-S" punctato-striatis ; 

 pygidio apice fulvo-hirto. 



Long. 4 1 mill.
