of one belonging to the present genus , but the pubescent an- 

 tennae, unarmed tibiae etc. show the true characters of Theopea; 

 the species is smaller than most of its congeners and differs in 

 the structure of the clypeus, the irregular punctured elytra and 

 their obsolete costae from T. impressa and other allied species; 

 the male differs probably again in having differently structured 

 head and antennae, the head and thorax in the present species 

 show also a metallic hue which is absent in any of the others. 



154. Hyphaenia apicicornis, n. sp. — Testaceous, the basal 

 joints of the antennae and the tibiae and tarsi more or less 

 piceous, thorax subquadrate, bifoveolate, elytra metallic blue or 

 green, semi-punctate-striate, the interstices longitudinally costate. 



0-^. Antennae longer than the body, with long fringes of hairs. 



9. Antennae shorter, without long hairs, the elytra gemi- 

 nately punctured. 



Length 2-3 lines.

 the frontal elevations transverse , eyes large , clypeus in shape 

 of a narrow transverse and perpendicular ridge, penultimate 

 joint of the palpi , incrassate , antennae longer than the body, 

 very slender and elongate, the first joint thickened, glabrous, 

 the second very small, the following joints very long and slender, 

 all furnished with long fringes of hairs, the lower six joints 

 black, the others llavous, thorax suliquadrate, one half broader 

 than long, the sides straight, slightly narrowed before the middle, 

 the angles not produced, the disc transversely sulcate, impunc- 

 tate, llavous, scutellum broad, llavous, elytra broader at the 

 base than the thorax , parallel , distinctly punctured in semire-

The size of this species is very variable, the females being 

 much larger, the long pubescent antennae of the male and the
