beneatli. liihruiii, posterior niarfiiii of iirotlionix, a spot on each side anteriorly, 

 spot oil scutelluiii and postsciitelluni, posterior angles of nietatliorax. tegiilEe, 

 anterior and median tibife beneath, the posterior at the tip and on the outer side, 

 the four anterior knees, a spot before the apex of the anterior tibife on the outer 

 side, apical margins of abdominal segments 1—5 all lemon-yellow, the band on 

 the first segment broadest, emarginate in the middle anteriorly, sometimes 

 nearly interrupted medially, bands on the remaining segments uneven on their 

 anterior edge; ))eiieath the segments are narrowly margined with testaceous, 

 the sides of the segments slightly rufous; wings hyaline, witli a very sligiit 

 yellow tinge, nervures and stigma yellowish, dorsulum with strong, spar.se pun<-- 

 tures; metathorax with a transverse excavation at the base, which is l)roadest 

 medially, and from which extends a short, distinct furrow, the posterior face 

 ratlier strongly depressed, rugose, the extreme lateral portion smooth ; legs red- 

 dish-fulvous, the coxae black, the posterior pair only, reddish beneath. Leiigtli 

 8—9 mm. 



"5^ . — Diflers from the female as follows: the antennje are shorter; front below 

 the antennae entirely, second joint of antennae beneath, the apical half of the 

 anterior and median femora on the outer side, line on the anterior tibiae, the first 

 joint of the anterior and median tarsi all bright yellow ; before the anterior 

 ocellus there is a strong depression or pit, from which extends the strong median 

 impressed line: the front has, in addition to the microscopic punctures, a num- 

 ber of strong, separated punctures ; the prothorax is strongly and sparsely punc- 

 tured, the punctures of the dorsulum slightly stronger and closer than in the 

 female; metathorax, except the base and extreme sides, which are almost the 

 same as the 9- rugose, the baud on the first segment of the abdomen broadly 

 interrupted. Length 7 — 8 mm. 



(Occurs in Texas, Illinoi?;, Kau.sas and Montana. Patton, in de- 

 scribing brevlcoritis, says " no fulvous color on posterior coxse." Tills 

 is an error, as I liave examined his type ; the coxae mentioned, both 

 in 9 S , having on the side a yellow line, which is broadest at the 

 apex ; the anterior coxte in front and a spot on the medial pair also 

 yellow.

 9- — Black ; orbits, the anterior pair broadest, face, clypeus, labrum, first two 

 joints of antennfe beneath, posterior margin of the prothorax, and a spot on 

 each side anteriorly, small round spot on scutellum and a transverse one on post- 

 scutellum, small spot at posterior angles of metathorax, first joint of median 

 tarsi, a sublunate spot on each side of the first abdominal segment, a narrow 

 band on the apical margins of the remaining segments produced iuto a large 

 spot laterally, all pale yellow ; the fascia on the second segment broadly inter- 

 rupted medially ; dorsulum strongly and sparsely punctured, the punctures more 

 compact in two longitudinal depressions, which are broadest towards tlie scutel- 

 lum; metathorax with a somewhat triangular, deep, shining excavation at the 

 basal middle, from which extends a strong furrow, which is twice as long as in 

 any of the preceding species, the rest of the metatliorax is microscopically punc- 

 tured; the coxae, metathorax, sides of the scutellum, face and the clypeus, with
