in pernanibucensis than in gundlachi, with the specuhim and the 

 principal veins more longitudinal. Most of the limbs are missing 

 in the unique type of pernambucensis. It is probable that the 

 Pernambuco material referred to gundlachi by Saussure" belongs to 

 this species. 



Type. — cf ; Bonito, State of Pernambuco, Brazil. January, 1883.

Size medium (for the genus), form slender but apprecia,bly de- 

 pressed; surface of body and limbs rather thickly clothed with short 

 hairs. Head of the transverse depressed type characteristic of the 

 genus; occiput and fastigium strongly and uniformly deplanate 

 declivent when seen from the side, the fastigio-facial angle rectangu- 

 late; interspace between the eyes broad, faintly ex- 

 ceeding the greatest length of the eye, inter-antennal 

 width of the frontal costa less than one-third of 

 the interocular width, dorsum of the fastigium and 

 cephalic section of occiput with a delicate medio- 

 longitudinal sulcus: facial line, when seen from 

 the side, slightly arcuate : palpi rather short, fourth 

 joint slightly shorter than the third joint, fifth joint 

 faintly shorter than the fourth, the fifth joint form- 

 ing a nearly equilateral triangle, the distal margin 

 truncate and but faintly shorter than the length 

 of the joint: eyes distinctly longitudinal pyriform, 

 the greatest depth, which is cephalad, contained 

 about one and a half times in the eye length: an- 

 tennae with the proximal joint broad, strongly de- 

 pressed. 



Pronotum transverse, the greatest caudal width 

 one and two-thirds times the greatest length, the 

 cephalic width about two-thirds the caudal width, 

 when seen from the dorsum the pronotum is ap- 

 preciably narrowed cephalad: cephalic margin of 

 disk faintly arcuate, caudal margin of disk bisinuato- 



truncate; disk of the pronotum with a medio-longi- .^^ , ,-
