 Aphycus angelicus HOWARD, Proc. U. S. Nat. Mus., vol. 21, 1898, pp. 241, 245. 



Female. Front and vertex nearly three times as long as wide, 

 slightly wider anteriorly, the dorsal orbits of eyes diverging; ocelli 

 in an acute-angled triangle, the lateral pair about half their own 

 diameter from eye margin, the front ocellus a little behind the center 

 of the front and vertex; the eyes nearly glabrous. Antennal scape 

 flattened and gradually becoming wider on apical half; pedicel but 

 little longer than the first three funicle joints combined; all funicle 

 joints distinctly wider than long and subequal in length, the fifth 

 twice as wide as the first; club oval, obliquely rounded at apex, 

 slightly wider at apex than the last funicle joint and as long as the 

 entire funicle. Wings uniformly ciliated; the oblique hairless streak 

 not quite reaching the posterior margin of wing, and interrupted a 

 little below the middle; none of the veins with bristle-like hairs. 

 Ovipositor protruded about one-fifth the length of abdomen. Length : 

 0.7 to 1 mm., exclusive of ovipositor. 



Front, vertex, and mesonotum rather dull orange yellow, the 

 mesonotum usually somewhat dusky, with the anterior margin of 

 the scutum sometimes blackish, but the axillary sutures usually not 

 lined with black; face, cheeks, and underparts pale yellowish white, 

 the venter of abdomen slightly dusky, the cheeks with a pale fuscous, 

 narrow, transverse band following the lower orbits of eyes; the con- 

 cealed part o'f occiput and of pronotum, the metanotum, propodeum, 

 and dorsum of the abdomen black; collar of pronotum and tegulae 

 whitish, former with a brown dot on each corner, latter with the 

 lower apical corner brown. Antennae excepting the club black, the 

 base of scape especially on inner surface whitish, the club snow white; 

 rarely the fifth funicle joint is also white. Legs concolorous with 

 underparts, the tarsi more yellowish, with tip of the last joint black- 

 ish; middle tibiae with a very faint, dusky annulus near the middle. 

 Wings with a faint brownish, integumentary, transverse cloud beyond 

 the oblique hairless streak, interrupted by a narrow, transverse, hya- 

 line band at end of stigmal vein, and by a still narrower, longitu- 

 dinal streak following posterior margin of wing opposite the marginal 

 vein; veins pale brownish. Exserted part of ovipositor yellow, the 

 apex dusky. 



Male. Similar to the female, but the front and vertex hardly over 

 twice as long as wide; the dorsal orbits of eyes parallel; face and 

 cheeks shorter; antennae slenderer, the pedicel and club proportion- 

 ately longer, pedicel as long as the first four funicle joints, the club 

 as long as the funicle and one-half the pedicel,
