DESCRIPTION OF NEW SPECIES OF STRATIOMYIDAE WITH NOTES ON OTHERS.
Jas. S. Hine.
In a collection of several species of Stratiomyidae from Ohio, and a number of western species, I find something which may be of interest to students of the family.
Specimens of Allognosta fuscitarsis, Say, show some degree of variation in the extent of the pale color on the disc of the abdomen. Some of the females have the abdomen nearly or wholly black. Specimens of A. obscuriventris, Loew, have the body entirely black; the legs are darker and the form is considerably smaller than fuscitarsis. Both species are common at Columbus during May.
