K0.2136. REVISION OF THE GENUS APHYCUS—TIMBERLAKE. 585 



ciliated; oblique hairless streak slightly wider below and inter- 

 rupted, with the cut-off portion rather widely separated from the 

 posterior border of the wing. Ovipositor barely protruded, at least 

 when material is mounted in balsam, probably not noticeably so 

 in life or dry material. Length: 1.1 mm. 



Front, vertex, and mesonotum rather pale orange yellow; face, 

 cheeks, underparts, and most of the abdomen much paler yellow; 

 center of occiput dusky; concealed part of pronotum, a narrow, 

 transverse line on the anterior margin of the mcsoscutum, the meta- 

 notum, propodeum, and a transverse band at the base of abdomen 

 blackish; collar of pronotum and the tegulae pale yellowish. Anten- 

 nal scape black, with the base, a narrow line on upper margin and 

 apical fourth whitish; basal third of pedicel and the first funicle 

 joint black; apex of the pedicel and rest of the funicle and club 

 yellowish white, with the second funicle joint somewhat dusky. 

 Legs pale yellowish, with the tip of the last joint of the tarsi black- 

 ish. Wings hyaline, the veins pale yellowish. 



Male. — Not known. 



Kedescribed from three females (cotypes) reared from Kermes 

 puhescens Bogue, Urbana, Illinois, June 25, 1908 (A. A. Girault), 

 loaned by the Illinois State Laboratory of Natural History. 



APHYCOPSIS, new genus. 



Comes closest to Aphycus Mayr, and is similar in general shape 

 of head and body, type of coloration, sculpture, and vestiture of 

 body. The structure of the abdomen also seems to be identical as 

 far as can be made out in the limited material at hand. The more 

 strildng differences are as follows: 



Female. — Antennal scape not flattened or expanded but clavate 

 cylindrical, much thicker at apex than at base, with a groove for 

 the reception of the pedicel; the pedicel nearly as thick at apex as 

 long, and but little longer than the first funicle joint; funicle about 

 as in Aphycus, but the pubescence is comparatively coarse and 

 bristle-like; club oval, somewhat obliquely rounded above at apex, 

 and about as long as the last three funicle joints combined. Vena- 

 tion of wings the same, except that the postmarginal vein is much 

 longer than m Apliycus, and nearly as long as the stigmal. The 

 tibiae of the middle legs enlarged at apex, and the middle tarsi 

 swollen. 



Male. — Not known. 



Type of genus. — Aphycus australiensis Howard.
