POMPILTTS. 207 



Hob. Mexico, Chilpancingo in Guerrero 4600 feet, Atoyac in Vera Cruz (H. H. 

 Smith). 



Antennae longish, stout, tapering towards the apex, the third and fourth joints 

 subequal; all the joints dull rufous beneath (perhaps yellow, discoloured by cyanide 

 of potassium). Eyes very slightly converging beneath ; the hinder ocelli separated 

 from each other by about the same distance they are from the eyes ; the apex of the 

 clypeus rounded ; the inner orbits of the eyes and the sides of the clypeus broadly 

 lemon-yellow ; the cheeks and clypeus with silvery pubescence. Prothorax about as 

 long as the head ; the apex bluntly angled and broadly lemon-yellow. Scutellum not 

 narrowed towards the apex, with a transverse mark at its base, and also one on either 

 side, yellow ; the postscutellum is also yellow, as well as the apex of the median 

 segment broadly. Median segment with a gradual slope to the apex. On the pleurae 

 there is an irregular mark below the tegulae, a smaller one below the hind wings, 

 and a large one over the middle coxae, yellow. Abdomen shorter than the head 

 and thorax united, subsessile ; the apical segment transverse, densely covered with 

 silvery pubescence ; the apex of the last ventral segment incurved ; the base and 

 apex of the basal segment, and the apices of the others, fulvous-yellow (perhaps lemon- 

 yellow X). Legs longish, slender ; the claws bifid ; the long spur of the hind tibiae 

 reaching beyond the middle of the metatarsus ; the hind coxae behind, the apex of the 

 fore femora, the four hinder femora beneath, the fore tibiae entirely and the others at 

 the base (the hinder pair very narrowly), the fore tarsi entirely, the base of the middle 

 tarsi, and the spurs, yellow or fulvous. The basal nervure is interstitial ; the anal 

 nervure in the hind wings is received beyond the cubital nervure ; the third cubital 

 cellule is shorter than the second at the top and bottom, the third at the top about 

 half the length it is at the bottom.

 Long. 7 millim. 



Had. Guatemala, Torola 1000 feet (Champion). 



Antennae moderately stout, covered with a microscopic down, not tapering towards 

 the apex, the apical joints dilated, the third joint distinctly longer than the fourth. 

 Head, especially from below the ocelli, densely covered with a silvery pubescence ; the 

 eyes distinctly converging beneath ; the ocelli in a triangle, the hinder ones separated 

 from each other by a much less distance than they are from the eyes ; the apex of the 

 clypeus distinctly transverse. Prothorax shorter than the head ; the apex angled 

 rather acutely. The thorax, especially the pleurae and the median segment, densely 

 covered with silvery pubescence ; the median segment with a very gradually rounded
