small submarginal spots near anterior margin and three large spots across 
disk, yellow; scutellum with narrow inconspicuous linear marking in each 
basal angle, a pair of reversed parentheses-shaped markings near anterior 
margin, apex and a median and two lateral lines extending anteriorly from it, 
yellow; forewing with base, humeral, commissural and costal margins, most of 
anteapical cells, apical cells, and claval suture, black, enclosing hyaline area. 
Face with median black marking of variable width over clypeus and clypellus. 
Holotype male, July 15, one additional male, August 28, and one male,

D. disparulus, n. sp., is closely related to D. dispar (Germar), but differs in its 
smaller size (the Germar species varying from 8.3-9.3 mm in length), in lack- 
ing the orange anteapical spot of the forewing and in the three large trans- 
verse spots of the pronotum. 
Dilobopterus lobatus, NEW SPECIES 
FIGURE 72, PAGE 118 
Length of male 7.5 mm. Head with median length slightly more than half 
interocular width and slightly more than one-third transocular width; ocelli 
located behind a line between anterior eye angles, each slightly closer to me- 
dian line of crown than to adjacent anterior eye angle, crown flattened be- 
tween ocelli; antennal ledges with anterior margins obliquely convex in lateral 
view. Forewing membranous discally and apically, veins distinct. Hindwing 
with jugal lobe greatly enlarged, extending almost to claval apex of forewing 
with wings in rest position. Other external structural characters as in D. 
axillaris, n. sp. 
Pygofer well produced, with macrosetae close-set and numerous, without 
processes; plates not extending posteriorly as far as pygofer apex, each tri- 
angular, gradually narrowed from base to apex, with multiseriate macrosetae 
on apical two-thirds; style extending posteriorly considerably beyond apex of 
connective, with a slight preapical lobe; connective short, very broadly Y- 
shaped, not keeled medially; aedeagus asymmetrical, shaft digitiform, arcuate, 
with a very large asymmetrical process arising dorsally at its base and 
broader than shaft, gradually narrowed and bifurcate apically; with an un- 
paired asymmetrical paraphysis which is elongate, bisinuate, and acute 
apically. 
Color of crown and pronotum sordid yellow, crown with a diagonal stripe — 
between eye and muscle impressions on anterior margin on each side, the 
margins of a median apical areole, and a basal spot behind each ocellus, 
black; anterior, lateral and posterior margins of pronotum broadly black, the 
inner margin of the black border very irregular in outline; scutellum black in 
basal half, apical half yellow; forewing hyaline, with base, humeral margin, 
commissural margin, costal margin, claval suture and an area across ante- 
apical cells, fumose to black, outlining a large membranous discal area of
