PRIOPHORUS SALICIVORUS Rohwer. new species. 



Figures 20, 21, 34, 35, 41, 47, 56. 



Female. — Length 4.5 mm.; length of antenna 3.5 mm. Clypeus 

 shining, strongly convex medianly, the apical margin broadly, shal- 

 lowly, arcuateW emarginate; supraclypeal foveae punctiform, small, 

 not much deeper than the antennal foveae; middle fovea oval in out- 

 line; ocellar basin with the lateral walls obsolete, the lower wall 

 poorly defined, rounded and unbroken ; antennal furrows obsolete be- 

 low the ocelli; postocellar area gently convex (incompletely defined 

 laterally by a foveaeform depression) ; postocellar furrow obsolete; 

 a faint depression behind the anterior ocellus ; antennae as in figures 

 20 and 34, short, not tapering, the third joint distinctly shorter than 

 the fourth, the apical joint subequal with the preceding; first inter- 

 cubitus obsolescent; third cubital cell on the radius, slightly longer 

 than the second; stigma short, broad at base, gradually tapering to 

 the apex; radiellan cell with a short distinct appendage; sheath 

 straight above, sharp apically tapering from the broad base, as seen 

 from below the sheath is narrow, ovipositor as in figures 41 and 47. 

 Black; four anterior tibiae and tarsi (the apical joints and all of 

 the intermediate tarsi are brownish) and the basal two-thirds of the 

 posterior tibiae, extreme base of the posterior basitarsus, whitish; 

 wings strongly brownish basally, subhyaline beyond the apex of the 

 stigma. 



Male. — Length, 4 mm. The male differs from the above descrip- 

 tion of the female in having the middle fovea more elongate and 

 deeper, breaking completely through the lower wall of the ocellar 

 basin; hypopygidium narrowly rounded; posterior tibiae entirely 

 brownish; antennae (see figs. 21 and 35) pale beneath, the third 

 joint broader than the fourth but simple ; radiellan cell with a very 

 short appendage. 



Type locality. — East River, Connecticut. 



Described from three females (one type) and two males (one 

 allotype) reared from larva collected on Salix by Chas. R. Ely, and 

 recorded under Bureau of Entomology number Hopk. U. S. 13656°. 



Type.~C?it. No. 21589, U.S.N.M. 



Larva. — Length, 11 mm. Black spot at vertex small; black spot 

 about each eye also small and not extending more than half way to 

 edge of cranium (fig. 56). Otherwise the larvae are similar to those 

 previously described, with dorsum pale between the grayish thorax 

 and the markings on eighth and ninth urites.
