1. Paneryma elongata, sp.n. ¢ 2. (Tab. X. fig. 19.) 
Black; head testaceous; legs rufous, the femora partly blackish; wings hyaline, with a median band, and a 
border at the base of the costa and another at the tip, brown. ‘ 
Length 7 millim. 
Head rounded; front as broad as the eyes, rufo-testaceous, the upper portion and the ocelli shining black ; two 
ocellar and four postvertical bristles; face testaceous, the oral margin slightly projecting, and above it 
there is a black transverse band; occiput greyish. Antenne rufous; the third joint three times as long as 
the second, and, with the exception of the base, brown. Thorax black, covered with a whitish dust, which 
gives it a greyish appearance ; the humeral callosities rufous ; scutellum black ; metanotum grey. Abdomen 
black, with a short whitish pubescence; male genitalia inferiorly with two club-shaped appendages ; 
basal joint of the ovipositor of the female broad, flattened, shining black, the second and third joints 
rufous, the third pointed. Legs yellowish-rufous; the fore and middle femora from the base to the 
middle blackish ; hind femora with a broad, blackish median ring, on the underside towards the apex 
with short black spines. Halteres yellow. Wings hyaline; the basal half of the costa, including the 
mediastinal cell, brownish ; beyond the middle a rather broad brownish cross-band, covering both cross- 
veins, but not reaching the costa, and a narrow brownish border at the tip, extending from the end of the 
second to the end of the fourth vein. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Three males and one female. 
CYRTOMETOPA. 
Cyrtometopa, Liéw, Monogr. Dipt. N. Amer. iii. p. 179 (1873). 
The generic name Cyrtometopa has been substituted by Low for Odontomera, Macq., 
because there was a genus Odontomerus, Grav., among the Coleoptera. The typical 
species is Odontomera ferruginea, Macq., from an unknown locality *. Macquart 
placed the genus in his group Tephritide (=Trypetinz), and according to him it 
formed a transition between them and the Ortalide. Low correctly included it among 
these latter. . 
This genus is allied to Richardia, but differs from it in having the femora not 
incrassated (though they are spinose beneath) and the cross-veins less approximated 
(the small cross-vein being nearly in the middle of the discal cell), as well as in the 
general rufous coloration of the body and the absence of a dark median band on 
the wings. Loéw mentions (J. c.) as an important character, “the front very much 
projecting in profile” (from which he derived the new name); but as he did not know 
the species itself, he has evidently taken this peculiarity from Macquart’s figure of the 
head, where the front is represented much too prominent, although it must be observed 
that owing to the deep excavation of the face the front appears to project. 
In the Mexican collections before me two species are represented, including the 
typical C. ferruginea :— 
Scutellum rufous, at the most with a blackish spot on each side; hind femora 
uniformly rufous... ew eee ee ee ew ww ee <Serruginea, Macq. 
Scutellum black; hind femora with a blackish ring. . . . . . . . « cinctella,v.d. W. 
* A second species, Odontomera maculipennis, Macq. (Dipt. Exot. Supp. 1, p. 211), is not congeneric, but, 
according to Low, probably belongs to the genus Celometopia, Macq. °
