 especially in the female, and usually with a 

 transverse fuscous line between the eves; 

 fastigium of vertex as in the last species and 

 connected as there with the deeply sulcate 

 frontal costa, which broadens gradually below 

 the ocellus and is there frequently punctate 

 with black on the margins; e^es prominent, 

 especially in the male; antennae somewhat 

 {$) or considerably (5) shorter than the 

 hind femora, testaceous basally, becoming

 broad, somewhat constricted mesially, ferru- 

 gineo-festaceous, more or less and irregularly 

 blotched with fuscous, the lateral lobes 

 marked as in the last species; median carina

 otherwise not higher than on the metazona, 

 the scutellum moderately pronounced, and 

 the disk of the metazona with sharp but not 

 high elevations, particularly in the female;
