Male. — Black: Labrum, mandibles except apices, lower part of 

 clypeus variable in extent, scape below, space between insertion of 

 antennae, minute spot on either side of anterior ocellus, anterior 

 orbits, posterior orbits, posterior border of pronotum, tubercles and 

 narrow lines on border of side of prothorax, tegulae, lateral spot on 

 scutum above tegulae, large lateral spots on scutellum, fascia on meta- 

 notum, curved fascia on dorsum of median segment sometimes 

 reduced to two spots or entirely wanting, spiracle and spot on sides of 

 median segment usually extended on lateral angles, spot on metapleu- 

 rae, irregular spot on mesopleurae, broad fasciae on tergites 1-6, the 

 first with broad, shallow, medial, anterior emargination, remainder 

 with a shallow anterior emargination on either side the mid-dorsal line, 

 ultimate tergite apically, first sternite except anterior lateral spots, 

 the remaining sternites except narrow basal border varying somewhat 

 in width on the several sternites, coxae except base more or less, tro- 

 chanters below, femora except broad stripe above and below which 

 stripes are united on posterior pair, tibiae except spot below on ante- 

 rior and middle pairs and occasionally on posterior pair, and tarsi, 

 yellow. The antennae and legs show no special modifications. The 

 second sternite bears a pair of short approximated processes and the 

 eighth a prominent discal spine. 



Female. — The female, with regard to general appearance and pat- 

 tern of macula tions, is essentially like the male. The black on the 

 clypeus is wanting or reduced to small basal lateral spots ; that on the 

 legs is somewhat more extensively developed. The yellow markings 

 are somewhat brighter in color and slightly better developed ; on one 

 female there is a pair of small discal spots on the scutum. Aside 

 from these differences in color and the absence of the secondary sexual 

 modifications found on the male, the description above will apply to 

 the female also. 



Length — 10-14 mm. 



In both sexes the flagellum below is yellowish or testaceous, 

 decreasing in intensity toward the apex. The black on the clypeus 

 of the male is variable in extent; it is never entirely absent and it 

 never spreads over the entire clypeus. On both male and female 

 the clypeus appears somewhat silvery, more evident on well-preserved 

 specimens of the female than on the male. The fasciae on the 

 tergites of the male show two distinct shades of color, lemon yellow 

 and yellowish white, somewhat variable in their arrangement; this
