Prosopotheca formosa Banks. 



Banks {Jour. N. Y. Ent. Soc, I, p. 125) has stated that Tmeticus 

 luxuosus Banks is the male of Lophocarenum venustum Banks. I have 

 compared the types of Lophocarenum venustum and Cornicularia for- 

 mosa Banks and feel sure they are the same species. This species is 

 related to Erigone by the apophysis on the patella of the palpus. It 

 lacks, however, the teeth on the margin of the cephalothorax and outer 

 margin of the chelicerae and its eyes are not arranged as in that genus. 

 In the form of the sternum and cephalothorax it is related to Proso- 

 potheca, but the auditory hair of the fourth metatarsus is on the distal 

 fourth.

Posterior eyes in a very slightly procurved line, median eyes slightly 

 smaller than the lateral, separated from each other by a little less than 

 their diameter, and from the lateral eyes by a little less than the 

 diameter of the lateral ; anterior eyes in a slightly procurved line, the 

 median eyes much smaller than the lateral, separated from each other 

 by one-half their radius and from the lateral by five-eighths their 

 ■diameter. Median ocular area a little longer than broad. Clypeus 

 narrower than the ocular area.

Posterior eyes in a straight line, equal, the median eyes separated 

 from each other by a little less than their diameter and from the lateral 

 by their diameter; anterior eyes in a straight line, about equal and 

 equidistant, separated by less than their radius. Median ocular area 

 a little longer than wide. Clypeus wider than ocular area. 

 Prosopotheca miniata Banks. 



The following notes are taken from one of the types in the Cornell 

 University collection. The form of the sternum and cephalothorax 

 as well as the arrangement of the eyes leaves no doubt as to its generic 

 position.
