NO. 2136. REVISION OF THE GENUS APHYCU8—TIMBERLAKE. 581 



underparts, including venter of abdomen and the legs, yellowish 

 white. Antennal scape black with the base, upper margin, and apex 

 narrowly yellowish; pedicel brown with apex yellowish white; first 

 two to four funicle joints brown gradually fading into the pale yel- 

 lowish of the last two or more joints of the funicle and the club. 

 Wings hyalme, the veins dilute yellowish. 



Alale. — Similar to the female in structural and colorational char- 

 acters except as to the antennae. Scape but slightly expanded, 

 widest beyond the middle, and about one-fourtli as wide as long; 

 pedicel shorter than tlie first funicle joint, its width at apex nearly 

 equal to its length; funicle joints not increasing in width, fii'st two 

 of nearly equal length, about one-half longer than wide, last two 

 slightly shorter but longer than wide; club elongate oval, hardly 

 wider than preceding joint and as long as the last two and one-half 

 of the fourth funicle joint, rounded at apex. The scape concolorous 

 with tlie face, its upper margin on the outer side blackish brown; 

 the pedicel, funicle, and club uniformly brown. Length: 1.3 mm. 



Redescribed from seven females, three males (cotypes) reared 

 from Eermes sp. on Quercus tindoiia, Ithaca, New York, January 

 25-30, 1890 (L. O. Howard), Insectary No. 763*'^ Originally 

 described from nine specimens all supposed to bo females, and it 

 seems impossible to determine which one of the above ten specimens 

 can not be considered a cotype. 



An additional female from Oklahoma is considerably larger, but 

 identical in coloration as far as preserved, the antennae being broken 

 off at the end of the fourth funicle joint. Differs only that the 

 fii-st funicle joint is hardly longer than wide, noticeably smaller than 

 the second, the pedicel proportionately a trifle longer, and the scape 

 slightly wider, its lower margin more fully rounded. Length: 1.8 

 mm. Specimen is labeled "Okla., 727."

2. AENASIOIDEA TENUICORNIS, new species. 

 Fig. 20. 



Female. — Front and vertex about three-fourths longer again than 

 wide; ocelli nearly in a right-angled triangle, the posterior pair 

 about one-half their own diameter from the eye margin; antennal 

 scrobes deep; eyes nonpubescent. Antennal scape expanded on 

 the basal half, rapidly narrowing so that most of the apical half is 

 nan'ow, the greatest width nearly one-third the length; pedicel a 

 little longer than the first and about equal to the second funicle 

 joint; all joints of the funicle longer than wide, not increasing m 

 width, filiform, first and last about equal, the second to fifth a little 

 longer and about three times as long as thick; club cylindrical like 

 the funicle, very little wider, as long as the last two joints and one
