A NEW SPECIES OF THE GENUS CHEILONEURUS. 



[Hymenoptera; Encyrticht.] 

 BY J. C. CRAWFORD. 



Cheiloneurus cushmani, new species. 



Female. Length about 1.75 mm. Varying shades of green, blue, 

 and purplish, the face and rear of head largely reddish testaceous; 

 pronotum, axilla?, and scutellum orange, suffused anteriorly with 

 brown; scape whitish, rest of antennae dark brown, first joint of funicle 

 shorter than pedicel; all joints of funicle slightly longer than wide, 

 antennal depression deep, sharply marked semi-circular, reaching 

 about half way up scape, above this the face with fine shallow thimble- 

 like punctures, at sides of antennal fossa becoming more like reticu- 

 lations; ocelli in an equilateral triangle, the lateral ones about their 

 own width from eyes; cheeks finely reticulated with raised lines; 

 mesoscutum very finely longitudinally lineolate, with a silky lustre, 

 and with many silver-white hairs; scutellum with thimble-like punc- 

 tures; apical tuft black; wings, except the hyaline bases, strongly in- 

 fuscated, the infuscation decreasing gradually toward tips of wings; 

 front and hind legs basally translucent whitish, front legs beyond 

 middle of femora light brownish; middle legs brownish, their tarsi 

 whitish; hind femora and tibiae brown, the tarsi whitish; abdomen 

 reticulated with fine rugulose. 



Male. Length 1.5 mm. Similar to the female; the antennal de- 

 pression not well marked, the sculpture coarser, especially in meso- 

 scutum, where anteriorly it is finely longitudinally rugulose and pos- 

 teriorly reticulate with fine rugulaa; entire insect varying shades of 

 metallic with more greenish than in female; hairs of mesoscutum 

 weaker and less numerous and therefore not so apparent; wings only 

 slightly infuscated, with a deeply infuscated spot at marginal vein; 

 scape whitish, rest of antennae light brown; front and middle legs 

 whitish, the apical part somewhat brownish; hind femora and tibiae 

 strongly brownish. 



Habitat: Vienna, Virginia. 



Type: No. 14097, U. S. National Museum. 



Six female and five male specimens from a series reared

Related to C. cnpreicollis Ashm. , which has the ocelli in an 

 equilateral triangle, but which has the joints of the funicle 

 elongate, the first much longer than the pedicel and the 

 mesoscutum is shiny and punctured.
