28 CEBAHBYCIDJE. 



This group, which, under another name, is Lacorclaire's group 

 Zarucides, includes only two genera Eurypoda and Neoprion ; the 

 latter is regarded by M. Laraeere as merely a subgenus. One 

 species only occurs within our faunistic area, the others are found 

 iu China, Japan, Malay Peninsula, Sumatra and Borneo. The 

 group has no close relationship with any of the other groups 

 included in our fauna. 



Genus NEOPRION. 



Neoprion, Lacord. Gen. Coleopt. viii, p. 131 (1869). 

 Eurypoda (Sound.) subgen. Neoprion (Lac.), Lameere, Ann. Soc. 

 Ent. Belg. xlviii, p. 9 (1904). 



Type, N. parandrceformis, Lacord. 



Kange. Andaman Is. and Malay Peninsula. 



Dorso-ventrally compressed. Head with the clypeus thickened 

 at its lower margin, triangularly depressed behind, limited above 

 by two oblique lines, from the junction of which a rather deep 

 impressed line or groove passes backwards on to the vertex ; man- 

 dibles shorter than the head, stout, nearly horizontal, incurved 

 and sharply pointed at the apex, carinate above, armed with a 

 tooth on inner edge ; eyes emarginate ; antennal supports 

 flattened, on a level with the thickened front border of the clypeus. 

 Antennae reach to a little beyond the middle of the elytra in the 

 cT , not so far as to the middle in the $ ; first joint stout and 

 very short ; third more than three times as long as the first, and 

 a little longer than the fourth aud fifth united ; fourth to eleventh 

 subequal in length, each with two narrow elongate poriferous 

 fossae on the anterior side, similar but much shorter fossae being 

 present near the apex of the third. Pronoturn of the <S as broad 

 as the elytra, with its sides nearly parallel from the slightly pro- 

 jecting front angles up to the lateral angles placed a little behind 

 the middle, thence converging obliquely to the base ; the front 

 margin somewhat bowed backwards in the middle:; the base 

 rounded in the middle, sinuate towards the sides ; disk feebly 

 convex, with a large, sparsely punctate, smooth area, roughly 

 octagonal in shape, over the whole of the central part, the spaces 

 between this and the lateral edges are very finely and closely 

 punctate and opaque ; pronotum of $ with its sides somewhat 

 convergent in front from the prominent lateral angles, strongly 

 punctured near the sides. Elytra somewhat flattened above, 

 broadly rounded at the apex, the sides narrow, nearly vertical, 

 with an obtuse costa running between each and the disk. Epi- 

 sterna of metathorax nearly parallel-sided, narrowed a little near 

 the apex, which is straightly truncate. Legs rather short ; femora 

 flattened fusiform ; the hind pair extended but little beyond the 

 second abdominal segment ; tarsi relatively short, with the first 

 joint scarcely longer than the second.
