[Vol. XII, No. 7, 
Female much like the male but more reddish in ground color, 
eyes widely separated, front slightly widest below with a rather 
extensive denuded patch but no distinct frontal callosity. Total 
length slightly less than the male measurement. 
The type male from which the accompanying drawing was 
made, was taken at Lyme, Ct., by B. H. Walden, and sent in by 
Dr. W. E. Britton. The female was procured at Wheatlands, 
Indiana, by Harold Morrison. 
The widely separated localities at which the specimens were 
taken indicates that the species has an extensive distribution. 
There does not appear to be the least doubt but that the two 
specimens in my possesion are sexes of the same species. 
Merycomyia Mixta n. sp. 
Female, length 21 millimeters. General color reddish brown. 
Eyes widely separated, front slightly widest below with an elongate 
denuded patch which narrows to a point above. Ocelli conspicu- 
ous. Thorax gray with darkened stripes above; wings wholly 
brown anteriorly, veins widely margined with the same color 
posteriorly, legs brown. Abdomen reddish brown with the lateral 
margins and a middorsal marking nearly black, venter rather 
dark. 
The type female from which the accompanying drawing was 
taken was procured at Bainbridge, Georgia, by J. C. Bradley, 
June 2, 1911. 
Stibosoma flavistigma n. sp. 
Female, length 17 millimeters. A black species with apex of 
the wings hyaline and a yellow marking including the stigma and 
reaching from the costa to the opposite side of the discal cell. 
Front and face black, antenna with the basal process of the 
third segment much produced. Thorax black, legs with all the 
tibise somewhat swollen, wing black, except the apex is hyaline 
and a patch in the region of and including the stigma is yellow; 
knob of the halteres green. Abdomen black, narrow margins of 
all of the segments, both dorsally and ventrally, gray. 
Type female, taken in Vera Cruz, Mexico, by D. L. Crawford.
