segment about as long as broad ; hind tibia five-eighths as long as the 

 tarsus ; metatarsus as long as the following segments united ; fourth 

 segment slightly longer than broad. 



Second ventral segment with two blunt tubercles ; process of third 

 segment compressed, with a narrow groove on its summit and two 

 anterior teeth, posteriorly it ends in a tooth directed caudad ; last 

 dorsal segment with 2 anterior processes sharp, tlie 2 apical ones very 

 small and close together. 



Squama obtuse, rather densely ciliate on the inner side and also 

 exteriorly at apex ; sagitta trigonal, its angles carinate, its apex acute, 

 about one-half as long as the uncus; uncus slender, shorter than in 

 texanns and less decurved.

"J*. Length about 13 mm. Labrum obtusely pointed; clypeus 

 strongly uniformly convex, arcuately emarginate in apical middle, 

 finely punctured ; front with rather large, separate punctures ; scape 

 not one and a half times as long as broad, third joint distinctly 

 shorter than fourth ; anterior ocellus large, subreniform ; pronotum 

 polished, with well-separated small punctures ; mesonotum with dis- 

 tinct, well-separated punctures, which are somewhat closer in the 

 depressed area ; mesopleura and scutellum similarly punctured ; propo- 

 deum normal; abdomen polished, with widely separated punctures 

 which become smaller posteriorly ; seen from above the first dorsal is 

 arcuately emarginate anteriorly ; second, third, and fourth dorsal seg- 

 ment depressed basally by about one-third the length of the entire 

 segment; processes of the third ventral and. apical segments essentially 

 as in tcxanus; second cubital on the radius slightly longer than the 

 distance between the recurrent veins. Black except where mentioned; 

 apical half of scape, flagellum (except apical spots on fourth and fifth 

 joints and greater part of club), face above level of antennae (the 

 lower margin has three indentations of black), most of clypeus, pro- 

 notum, large circular spot below tegulae, tegulae, spot above, two fan- 

 shaped spots on anterior part of mesoscutum and a small spot in front 

 depression, spot on scutellum and angles of propodeum yellow; abdo- 

 men wdth broad dorsal and ventral bands on apex of all segments 

 reddish yellow (due in part to potasium cyanide?); legs reddish- 

 yellow, knees yellowish ; wings vitreous, hyaline, slightly yellowish in 

 stigmal region; venation pale brow^n." 



5. Black except as follows : antennae rufo-piceous ; posterior orbits 

 dorsally, narrow line on inner orbits up to and filling the eye emargi-
