the pedicel combined. Wings small, reaching but little beyond apex 

 of abdomen; uniformly ciliated; oblique hairless streak wide espe- 

 cially on its lower half and separated by about one row of cilia from 

 the hairless streak on the posterior margin of wing; stigmal vein thick 

 and not much narrowed at base. Ovipositor protruded about one- 

 fourth the length of the abdomen, the exserted portion pubescent. 

 Pubescence of head and thorax scanty. Length: 0.6 mm., exclusive 

 of ovipositor. 



General color, pale orange yellow, the head and underparts slightly 

 paler; antennae and legs concolorous; exserted portion of ovipositor 

 blackish at apex. Wings hyaline, the veins pale brownish. Pubes- 

 cence of head and thorax whitish. 



Male. Similar to the female, but head, thorax, and underparts 

 paler, more gamboge yellow, and the abdomen deep bright orange 

 yellow. Length: 0.55 mm. 



Redescribed from eight females, one male (co types), Truckee, Cali- 

 fornia, September, 1885 (A. Koebele), Insectary No. 3821x, one 

 female not belonging to the type series. Host unknown; neither of 

 the insects mentioned by Howard seem likely to be hosts, as all the 

 closely allied forms have been reared from Dactylopiine coccids.

Genus AENASIOIDEA Girault. 

 Aenasioidea GIRAULT, Can. Ent., vol. 43, 1911, p. 171. 



Female. Differs from ApTiycus Mayr only in the following partic- 

 ulars: Teeth of the mandibles slightly less equal, the upper two 

 being blunt and broad, the lower a little shorter and more acute; 

 antennal pedicel shorter, no longer than the first two funicle joints 

 combined, sometimes no longer than the first joint alone; funicle 

 joints longer and narrower, all usually longer than wide, rarely with 

 the terminal joints a little wider than long, and not increasing greatly 

 in width distad, the club smaller and oval; flagellum on the whole 

 therefore more cylindrical, but the scape is flattened and usually 

 widely expanded below, as in many species of Aphycus. The fifth 

 ventral sclerite of the abdomen reaching to the anus and inclosing 

 the ovipositor, but not plowshare-shaped as originally described, 

 except possibly to a slight degree after death through shrinkage. In 

 shape of head, thorax, and abdomen, in sculpture, vestiture, type of 

 coloration, and venational characters not differing from ApJiycus. 



Male. Like the female except, that the head is thinner antereo- 

 posteriorly and wider, the front and vertex therefore wider; eyes 

 smaller and the ocelli larger; antennae of a more primitive structure 

 than in the female, the scape being flattened but not much expanded 

 below, the pedicel shorter than the first funicle joint, the funicle
