dorsal disc behind the shoulders fusco-himacnlate ; vertex narrower 

 than one of the eyes in the male, subequal in the female, little 

 narrowed forward, transversely carinate, the carinulae rather roundly 

 CO mpresso- elevated on each side, middle lightly carinate, in profile 

 not advanced beyond the eyes ; frontal costa arcuately elevated 

 between the antenna;, rather widely sulcate, the rami straight ; 

 antenna; short and not as long as the head, inserted distinctly below 

 or anterior to the eyes. Pronotuni depressed, anteriorly truncate, 

 dilated between the distinct humeral angles, carinse laterally little 

 compressed just behind the shoulders, the subulate apical process 

 lengthily extended backward beyond the posterior femoral apices ; 

 dorsum rugose tuberculate, between the shoulders bearing abbre- 

 viated carinuL-e ; median carina bicristate forward, strongly sinuate 

 just before the shoulders, the forward crest often little higher than 

 the second elevation ; median carina posteriorly very little com- 

 pressed and straight, minutely serrate ; lateral carinse strongly com- 

 pressed at the shoulders, posteriorly on the process serrulate ; pro- 

 zonal carinfe, short, little expressed and parallel ; posterior angles 

 of the lateral lolies distinctly flattened c^uadrate, the posterior angles 

 obtuse, behind obliquely truncate. Elytra oval ; wings fully ex- 

 plicate, extended backward beyond the pronotal process in the 

 female, or not at all in the male. Anterior femora strongly com- 

 pressed, margins above sinuate, below foliaceo-trilobate, the middle 

 lobe large with sinuate margin ; posterior femora scabrous and 

 having the external area between the carinte tuberculose, the 

 external carinse bidentate or lobate in the female ; hind tibise 

 fuscous marked with white at the middle and near the knees ; first 

 article of the posterior tarsi longer than the third, the third pulvilli 

 little longer than the rest. 



Entire length of body, male and female, 9*8-11 '5 mm. ; pronotum 

 9-10"5 mm. ; posterior femora 4-4*5 mm.
