DESCRIPTION OF NEW SPECIES OF STRATIOMYID,E 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. obscurivenlris, Loew, have the body entirely black; 
the legs are darker and the form is considerably smaller than fusci- 
tarsis. Both species are common at Columbus during May. 
Ptecticus (Sargus) trivittatus, Say. 
A species of Ptecticus taken abundantly at Cincinnati by Chas* 
Dury agrees so well witli Say’s Sargus trivittatus that I cannot con- 
vince myself that it is anything else. Specimens when first taken 
agree more closely with Say’s description than the same specimens 
do after they have been in the cabinet awhile and have become dry. 
The green color that Say mentions is present in some while others 
are yellowish or brownish. The broad, dusky band that Say de- 
scribed as appearing on the basal part of each abdominal segment 
beyond the second is conspicuous, being of greatest extent on the 
fifth and sixth. 
Euparyphus major n. sp. 
Female, length 9mm. Head yellow; vertex, a wide stripe from 
vertex to mouth, widened at antennae and spreading out on the 
cheeks in the region of the mouth, antennae and occiput, black ; eyes 
hairy. Thorax shining; apical two-thirds of scutellum including 
the spines, an irregular spot each side between the scutellum and 
base of the wing, four longitudinal lines abbreviated behind, a tri- 
angular spot befere the base of the wing, and two spots beneath it, 
bright yellow. There is also a minute yellow spot on each side of 
the thorax posterior to the lower corner of the eye, the yellow mark- 
ings on the disc of the thorax extend for one-fifth of their length 
behind the transverse suture, while those on the sides extend from 
the humerus to the transverse suture. The femora except at base 
and apex are black, and the last three tarsal joints are brown, re- 
maining parts of the legs are yellow; wings hyaline, veins dull yel- 
low, halteres bright yellow. Abdomen black; a spot under the scu- 
tellum, a spot each side on the lateral part of the second segment,
