depression slightly striated in the punctate portion. Scutellum as in inter- 
rupta. Venter with a narrower impunctate discal area. Hind tibiae with 
very weak spinules. 
Length, 2.5 mm. 
Type, Sarita, Tex., December 1, 1911. Taken on sand hills (C. A. 
Hart) . 
CoRIMELAENA NANELLA McAtee, sp. n. 
This species is most easily separable from pulicaria by the small 
extent of pale color on the corium. Only the outer edge laterad of the 
cubital vein is so colored, while in pulicaria the triangular area between 
the cubitus, brachium, and claval suture, also is pale. I have seen no 
real intergradation between these types of coloration. Nanella averages 
smaller in size, ranging from 2 to 2.5 mm. The color is more metallic, 
being bronzy black, and the body is distinctly thicker than in pulicaria. 
This species is not a small form of the new species described below, 
because it has the broad brachial field characteristic of Jateralis and 
pulicaria. 
Type, a male, Virginia, near Plummers Island, Md., June 17, 1913, 
(W. L. McAtee), In writer’s collection. Paratypes, two males: Belts- 
ville, Md., June 15, 1913 (W. L. McAtee) ; and Chesapeake Beach, Md., 
June 18, 1914 (L. O. Jackson). Allotype, Forest Glen, Md., June 13, 
1915 (W. L. McAtee). 
To the above description, which is by Mr. McAtee, I add the details 
of structure in key. 
CoRIMELAENA HARTI, Sp. n. 
Male and Female.—Glossy black, apex of tylus, chitinized portion of 
wing laterad of the outer venational suture, lateral margin of abdominal 
segment beyond the exposed portion of wing in both sexes, and margin 
of apical segment of female yellow. Antennae yellowish testaceous. Legs 
black, tibiae castaneous, tarsi yellowish. 
Male—Head much broader than long, with large subcontiguous dor- 
sal punctures, slightly sinuate in front of eye, subtruncate at apex, the 
tylus with a small round dorsal wart at apex. Pronotum with large and 
interspersed minute punctures on almost the entire dorsum, the transverse 
middle depression nearly absent, posterior margin slightly declivitous, so 
that there is a decided depression between pronotum and base of scutel- 
lum, the latter about as long as broad, the apex obtusely rounded, in type 
with a slight central emargination which may be abnormal, in profile with 
a slight angle at base of posterior half, the declivitous portion nearly 
straight, punctures large and deep, especially so laterally, the disc with 
smaller punctures. Apex of chitinized portion of wing acute, venational 
suture as in lateralis. Hypopygial plate densely punctate, its upper margin 
doubly emarginate (Pl. XIX, Fig. 58). Hind tibia without postero-dorsal 
spinules. 
Female.—Similar to the male, but the apex of scutellum is regularly 
rounded. The basal genital plates are broad, with punctures on the upper 
half (Pl. XIX, Fig. 66).
