hyalinp, slightly iufuscated at the apex; second abscissa of the ra- 

 dieus about one-third the length of the third- Female: Length 9 mm. 

 Chinandega, Nicaragua, and Champerieo, Guatemala (Baker.) 



Clypeus not much wider rhmi its greatest length, shining, weakly 

 sparsely punctured, especially in the middle. Face impunctate, shin- 

 ing. Front and vertex strongly, moderately closely punctured; in the 

 center of the lower part of tlic front is a small Init distinct deep 

 fovea longer than wide and iinrrowed above and l)el()w. Hinder ocelli 

 separated from each other by a slightly less distance than tliey are 

 from the eyes- Vertex weakly, the temples .sharply keeled- Base of 

 pronotuim slightly broadly jiiojecting in the michlle; the sides are 

 rounded. Apex of scutellum ol)liquely narrowed towards tlie center; 

 the scutellum is much more strongly punctured than the mesonotiini; 

 its apical slope is smooth ami deep; in the center of the upper half 

 is a deep narrow furrow; the .post-scutellu-m; it is transverse below, 

 above it is slightly rounded; it has a more distinct oblique slope than 

 the scutellum. The base of the sides of the metanotum is straight, 

 oblique, the end of this part being broadly rounded and clearlv sep- 

 arated below from the lower part, forming an angLe but not a tooth- 

 Sides of metanotum punctured and pilose, the middle smooth- There 

 is a distinct smooth impressed line down the center of the basal half 

 of the mesonotum; there is an obscure yellow line in the center. The 

 pronotum is much more stronghly and closely punctured than the 

 mesonotum. 



The following synopsis may be useful in separating these ;ind re- 

 lated species: 



1 (2) Length 7 mm. Clyieus closely longitudinally punctured 



and striated; apex of scutellum and postcutellum forming 

 one slope, mesonotum as strongly punctured as the sides of 

 the pronotum; wings not tinged with yellow mexicanus Cam. 



2 (1) Length over 7 mm- Olypeus weakly sparsely punctured; 



apex of scutellum and postscutellum not forming one slope; 

 mesonotum not so stiongly punctured as the pronotum; wings 

 clearly yellow- 



3 (4) Entire head and body covered densely with pale fulvous 



pubescence and pale hairs aztecus Cam. 



4 (3) Entire head and body not densely covered with longish 



pubescence. 



5 (6) Apex of scutellum furrowed in the middle, sides of meta- 



notum at the base broadly roundly projecting, the projection 

 not clearly separated from the lower part centralis Cam. 



6 (5) Apex of scutellum not furrowed; the projection on meta- 



notum tooth like, clearly spearated from the lower par 



arisonaensia Cam.
