1901, at flowers of Eriogonum (M. Cary). Related to varicolor- 
atus and glenensis, but differs from both by the bicarinate scu- 
tellum, position of the ocelli, shape of squamae and postscutellar 
spine, and other minor characters. 
Oxybelus glenensis, n. sp 
?. Length 5.5 mm. Insect black, covered with a short dense silvery 
pubescence; face with pubescence rather longer than that on the remain- 
ing portion of the body; occiput and face with very close, medium-sized 
punctures, those on the cheeks rather larger and more sparse; clypeal 
process fairly prominent; mandibles light ferruginous, tips and bases dark; 
ocelli large and prominent, normally situated; scape of antennae light- 
colored in front, flagellum pale rufous.- Prothorax not carinate, and 
rounded at the sides, with punctures fairly close. Mesonotum without a 
carina, scutellum with a very faint one, also with a narrow membranous 
margin, and punctured about as mesonotum; squamae apparently touching 
in the middle and with weak lateral curved points which very slightly 
surpass the tips of the squamae; postscutellar spine about one-third wider 
at tip than at base, truncate and light colored distally, concave above; 
tubercles with a light spot; pleura punctured as mesonotum, metapleura 
finely striate, upper portion of posterior face of metathorax striated and 
with pubescence longer than on any other portion of the body; depression 
~ below spine punctate above, almost smooth below; ldwer portion of pos- 
terior face finely punctate. Abdomen with close extremely fine punctures, 
first and second ventral segments finely and very sparsely punctured, re- 
maining ones almost impunctate; abdomen with light-colored entire bands 
on segments 1-4, these bands slightly ferruginous basally; two apical 
segments bright rufous, hardly constricted between segments. Legs black, 
all femora white at distal end, intermediate and posterior tibiae white 
basally and apically, anterior tibiae yellowish white, all tarsi whitish. 
Wings only faintly clouded, almost hyaline, nervures Beoueh 
6. Unknown. 
Type, Glen, Sioux county, Nebraska, altitude 4,000 ft., August 
18, 1906 (P. R. Jones). This species is related to variogloratag 
from which it is very distinct, as set forth in the description.
