5i6 The Ohio Naturalist. [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 m}^ 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 

 tibiae 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.
