KEY TO MALES OF AMBLYDISCA 



1. Pygofer with posterior margin convex; aedeagus without unpaired 



ventral process A. multiguttata (Stal) (fig. 106) 



Pygofer with posterior margin truncate; aedeagus with unpaired 

 ventral process 2 



2. Aedeagal shaft in ventral aspect with a constriction. 



A. rubriventris (Signoret) (fig. 105) 

 Aedeagal shaft in ventral aspect without a constriction. 



A. major, new species 



Amblydisca major, new species 

 Figure 107 



Length of male 11.5 mm. Crown of head with weak M-shaped 

 elevation bordering posterior margin, without a longitudinal carina 

 laterad of each ocellus. Male pygofer truncate apically, as in A. 

 rubriventris (Signoret) (fig. 105c) with a number of slender elongate 

 microsetae on apical half of disc; plates not extending posteriorly 

 quite as far as pygofer apex; style with distinct preapical lobe, apex 

 curved mesad and subangulate; aedeagus v^^ith an unpaired ventral 

 anteapical process, shaft in basal half much broader than in A. 

 rubriventris (Signoret). Color of entire dorsum and face brown, forewings 

 with a number of small, pale fenestrae. 



Holotype male, Xico, Vera Cruz, Mexico, on indefinite loan to 

 USNM from NCS. An additional male from Nicaragua and two 

 specimens from Jalisco, Mexico, have been studied. 



This species is related to A. rubriventris, from which it can be 

 distinguished by its larger size, and the genital characters mentioned 

 in the description. 



21. PROCONOPERA, new genus 



Figures 108-109 



Type-species: Amblydisca pullula Jacohi, 1905c: 166. 



Length 13-15 mm. 



Head with median length less than interocular width, disc with 

 pubescence; entire clypeus with broad, shallow, median depression 

 which bears a median carina; face densely pubescent below; clypellus 

 produced, contour of its lower half at a right angle to profile of clypeus; 

 other characters as in Aulacizes.
