NO. 2136. REVISION OF THE GENUS APBYCUSTIMBERLAKE. 631 



Male. Front and vertex about one-fourth longer than wide; 

 ocelli in an equilateral triangle or nearly so, the posterior pair about 

 their own diameter from the eye margin. Antennae very nearly 

 as in the female, but the club slenderer, more truncate at apex, and 

 as long as the last four joints combined. Length: 0.7 to 1.2 mm. 



Coloration as in the female, but the face, cheeks, and underparts 

 decidedly paler than no turn or chrome yellow, the prepectal plates 

 concolorous with the rest of pleura; metanotum, propodeum, and 

 central part of the dorsum of abdomen darker brown. Antennal 

 scape and pedicel as in the female, but the funicle and club pale 

 brown with the sixth funicle joint sometimes a little paler. 



Redescribed from four females (cotypes) reared from Lecanium 

 nigrofasciatum Pergande, Carbondale, Illinois, June, 1908 (A. A. 

 Girault); two males from the same host, Lawrence, Massachusetts, 

 February 11, 1899 (Geo. B. King) ; two females, one male reared from 

 same host, February 5, 1897, Insectary No. 472; two females, 

 Salem, Ohio, September, 1903; and a large series of both sexes reared 

 from the same Lecanium, Mount Alto, Pennsylvania, during May 

 and June, 1913 (F. L. Simanton), Quaintance No. 6130.

32. APHYCUS ERIOCOCCI, new species. 



Female. Front and vertex three times longer than wide; ocelli in 

 a strongly acute-angled triangle, the posterior pair almost touching 

 eye margin and about their own diameter apart; antennal scrobes 

 broad and shallow; eyes nonpubescent. Antennal scape strongly 

 flattened but not expanded below, the lower margin gently curved, 

 a little over four times as long as wide; pedicel as long as the first 

 three and one-half of the fourth funicle joint combined; first three 

 funicle joints equal in length, the fourth slightly longer, the last two 

 equal and a little longer than the fourth, all increasing gradually and 

 slightly in width distad, the sixth about one-half wider again than 

 the first, the first three a little wider than long, the sixth considerably 

 so, but the fourth and fifth about as long as wide; club elongate oval, 

 tapering distad, and slightly obliquely truncate at apex, one-third 

 wider again than the preceding joint and as long as the last five 

 funicle joints combined. Wings uniformly ciliated; oblique hairless 

 streak not reaching to the stigmal vein and interrupted below, the 

 small cut-off portion well separated from the posterior margin of 

 disk and from the basal streak; the latter reaching nearly to the 

 angulation or to a point opposite the end of the stigmal vein. Ovi- 

 positor protruded about one-eighth the length of the abdomen. 

 Length: 0.9 mm., exclusive of ovipositor. 



Front, most of occiput, face, and cheeks pale chrome yellow, be- 

 coming whitish at the oral margin, and a very narrow blackish line
