A single male, with apices of antennae wanting and right fore wing 

 on pin, without locality label but a name label in Norton's handwrit- 

 ing, is in the collection of the Academy of Natural Sciences of Phila- 

 delphia. This specimen agrees perfectly with the original description 

 and is with but little doubt from the type series. It may be designated 

 as electotype. 



The species is closely allied to pruni but may be easily separated by 

 the middle fovea breaking through the crest. It agrees well with the 

 species here described as mrginianus ^ and it is not unlikely that it will 

 prove to be the male of that species. 



Male. — Length, 5.5 mm. Anterior margin of the clj^peus broadly, 

 shallowly, arcuately emarginate; lobes small and obtuse; median 

 fovea deep, well defined, elongate, breaking through the frontal crest ; 

 ocellar basin obsolete dorsally ; a faint impression in front of anterior 

 ocellus; antennal furrows present but not strong; postocellar area 

 very narrow, distinctly limited laterally, and with a distinct median 

 fovea anteriorly; postocellar furrow wanting; third antennal joint 

 distinctly shorter and slightly broader than the fourth, with a faint 

 swelling at base beneath ; stigm.a rather broad, about three times as 

 long as greatest w^idth which is at base and from which it tapers to 

 apex ; first intercubitus obsolescent ; first abscissa of radius shorter than 

 the second, which is subequal with the third; second cubital on the 

 radius about two and one half times as long as third intercubitus; 

 second recurrent distinctly before the middle ; radiellen cell closed and 

 with a short appendage; hypopygidium broadly rounded apically. 

 Black; palpi, four posterior trochanters, four anterior tibiae and 

 tarsi, posterior tibiae and tarsi, except apical tarsi and apices of 

 tibiae which are brownish, whitish ; anterior femora reddish beneath ; 

 wings brownish to apex of stigma, then hyaline ; venation dark brown.

Distribution. — Farmington, Connecticut. 



PRIOPHORUS VIRGINIANUS Rohwer, new species. 



It is not unlikely that more material will prove that this is the 

 undescribed female of aequalis (Norton). 



Female. — Length 5 mm. ; length of the antenna 4.25 mm. Clypeus 

 strongly convex medianly ; anterior margin broadly, arcuately emar-
