Ko. 221)3. PARASITIC CIIALCIDOID FLIES— TIMBERLAKE. 189 



and nearly tvv'ice as wide as the first joint; club solid, ol)liqiiely trun- 

 cate from apex to basal third, as long as the last four funicle joints 

 combined. Mandibles about as in atriventris. Thorax moderately 

 convex, the axillae nearly level vnih the scutellum, the disk of the 

 latter moderately convex, abruptly rounded and declivous at the 

 sides and apex. Wings very nearly as in atriventns, the speculum 

 a, little more distinct and nearly parallel with the apical part of the 

 submarginal; the submarginal slightly angulate at the distal fourth 

 and somev/hat thicker at the angle; the stigmal vein less curved at 

 base and thinner. Abdomen narrower than thorax and about two- 

 thirds as long, the sides subparallel, the base somewhat narrowed 

 and the apex well rounded; the ovipositor slightly protruded. 

 Sculpture as in atriventris, except that the face has fmely impressed, 

 fingerprint-like, transverse aciculations, the frontovertex with the 

 pin-punctures more numerous and distinct, and the axillae and scu- 

 tellum with a much more deeply impressed or roughened sculpture, 

 the surface, therefore, being much less shining; on the axillae the 

 sculpture is subreticulate, but that of the scutellum, on the whole, 

 is more of the fingerprint type, with the aciculations close-set and 

 longitudinally arranged. Face, cheeks and mesoscutum v/ith a 

 whitish pubescence, thicker on the head but more prominent on the 

 thorax; the metapleura and hind coxae with the usual appressed 

 silvery white pubescence. Length of bod}^, 1.91 (to 2.20); length of 

 head, 0.65; width of head, 0.60; width of vertex, 0.159; length of 

 eye, 0.46; width of eye, 0.29; length of antenna, 0.96; width of 

 mesoscutum, 0.585; length of forevving, 1.70; width of forewing, 

 0.63 ; length of exserted part of ovipositor, 0.094 mm. 



General color intermediate between orange and Mars yellow (R..), 

 the face, cheeks, postorbital region, most of occiput and prothorax, 

 the pleura and base of abdomen often a little paler and more yellow- 

 ish; mesoscutum in front of the curbed parapsidal lines often darker 

 or about Sudan brown (R.) or becoming even darker medially and 

 anteriorly; collar of pronotum transparent whitish or yellowish along 

 the posterior margin; tegulae white with the apical half pale brown; 

 metanotum, propodeum and most of the dorsum of abdomen brown- 

 ish black; venter of abdomen like thorax, or sometimes rather dark 

 brown except toward the base and medially; the ovipositor yellow. 

 Antennae concolorous with face, the club and sometimes the funicle 

 rather dark brown. Legs concolorous with pleura or sometimes paler 

 yellow, the front and middle tibiae pale brown, the middle pair some- 

 times dark brown; hind femora on the upper margin of the inner 

 surface, and the hind tibiae brown to blackish brown; tibial spur 

 yellowish, the tarsi yellowish white with the apical joint dark brown.
