PoNTANiA CONSORS, new species. 



Larva and Galls.— Vi^d^x, Jour. N. Y. Ent. Soc, VI., June, 1898, 

 p. 121. 



Fejnale. — Length, 4.5-5. mm. ; slender ; surface shining, not at all 

 pubescent ; clypeus distinctly emarginate, lobes triangular ; ocellar basin 

 distinctly defined, but with walls rounded ; crest rather sharp, unbroken ; 

 fovea oval, distinctly defined; antennte short, joints 3 and 4 subequal ; 

 sheath moderately broad, regularly rounded at tip ; clothed with a rather 

 dense fringe of long browish hairs ; cerci narrow and elongate ; claws 

 deeply cleft, rays subequal ; venation normal, upper discal cell of hind 

 wings elongate, as long as or exceeding lower. Colour black ; orbits 

 and face brownish-yellow, including the area between the bases of the 

 antennae; pronotum, teguhe and legs for the most part and venter of 

 abdomen yellowish or resinous ; bases of coxi« black ; posterior tarsi 

 strongly infuscated ; sheath dark brown ; apical half of abdomen, dor- 

 sally, resinous, more or less infuscated ; veins and stigma dark brown or 

 strongly infuscated ; wings hyaline, or nearly so. 



J/a/,?.— Length, 4.5 mm. ; structural characters in general as in 

 female ; antennae rather more robust, short, scarcely as long as head 

 and thorax ; upper discal cell of hind wings distinctly elongate and 

 exceeding lower cell in length. Colour in general as in female ; wing 

 veins darker, almost black, and dorsum of abdomen altogether black ; 

 procidentia not longer than wide. 



Described from one female and two males reared by Mr. Dyar from 

 willow galls on Salix sericea. In the table of the genus given in my 

 Revision of the Nematinse (Bull. 3, Tech. Ser., Div. Ent. U. S. Dept.) the 

 female of this species would fall next io pisum, Walsh, from which consors 

 is readily distinguished by having a somewhat elongate third cubital cell, 

 and by the elongate upper discal cell in the hind wings. The male of 

 this species falls in the table next to pomuin, from which it is readily 

 separated by the long upper discal cell in consors much exceeding lower 

 cell.
