and Species of Cohopicra. 405 



eleventh joints forming a short ovate chib ; the ninth, tlic 

 hu-iLi:est, shininy, and sh'ghtly embracing tiie tenth and eh-vcntli, 

 which are spongy. Kyes hirge, not divick'd l)y a canthns. 

 Tiiorax transverse. Scutellum triangnhxr. Elytra elongate, 

 slightly rounded at the sides. Abdomen composed of six seg- 

 ments ; the basal one small and much hidden. Anterior coxa3 

 rather large, conical. Metasternum short. Intermediate and 

 posterior tibiae furnished with two spurs at the apex, those to 

 the intermediate pair being the longer ; anterior tibina elongate, 

 not much widened at the apex, with two strong teeth on the 

 outer edge, and a smaller one nearer the base. Tarsi long 

 and very slender, longer than the tibia, the anterior pair the 

 longest, nearly twice as long as the tibia ; the basal joint very 

 short (club-shaped), not reaching beyond the apical tooth of 

 the tibia ; the second to fifth joints very long and slender, the 

 fifth the longest. The claws very long, slender, very slightly 

 curved, simple, about four fifths the length of the claw-joint. 



I have placed a note of inteiTogation to the number of joints 

 to the antennas, as the eighthjoint is somewhat doubtful ; there 

 is, however, an apparent suture between it and the first joint 

 of the club, and 1 am not sure that I am coiTect in terming it 

 a joint. I mention this, particularly as the stnieture of the 

 antennre inclines me to place the species in the vicinity of 

 Hajmlonychus (Hybosorida;), which should have only ten joints 

 to the antennae. Many of its characters, however, suggest an 

 affinity Avith Serica ; but I believe that it is rightly placed 

 here.

The clypeus is not separated from the forehead by any dis- 

 tinct line ; it is transverse, and has the angles slightly rounded. 

 The thorax has the anterior angles slightly prominent, scarcely 

 acute; the sides are gently reflexed, very gently narrowed 

 in front ; the base is broadly lobed in the middle. The elytra 

 are furnished with a stria near the suture. The underside of 

 the body is very shining, not punctured. The three teeth on 

 the outer edge of the anterior tibifc are sharp, the basal one
