NO. 2136. REVISION OF THE GENUS APHYCUS—TIMBERLAKE. 605 



Male. — Front and vertex about one and three-fourths times as long 

 as wide; ocelli in an equilateral triangle, the posterior pair a little over 

 one-half their own diameter from the eye margin. Antennal scape 

 hardly more than one-fourth as wide as long, its lower margin slightly 

 curved, widest before the middle and tapering gradually to the apical 

 end; pedicel as in the female, rest of antenna broken off in single 

 available specimen. Wings uniformly ciliated, showing no trace of 

 the ciliary banding. Length, 1.2 mm. 



Coloration nearly as in female, but the upper half of the center of 

 occiput, the concealed part of the pronotum, the metanotum, propo- 

 deum, and dorsum of abdomen blackish, the latter with the sides 

 behind the vibrissae narrowly bright yellow; collar of pronotum and 

 the tegulae whitish, the former with a very pale brownish dot on each 

 corner, the latter not marked. Antenna as much as known colored 

 as in the female, but the pale parts more yellowish. Legs as in female 

 except that the tibial dots are a Jittle heavier. Wings entirely hya- 

 line, the veins pale yellowish. 



Redescribed from five females, one male (cotypes) reared from a 

 Lecanium on osage orange. Las Cruces, New Mexico (T. D. A. Cock- 

 erell).

 Fig. 19. 



Female. — Front and vertex about twice as long as wide; ocelli in 

 an acute-angled triangle, the posterior pair about one-half their own 

 diameter from the eye margin ; eyes with a very fine, sparse pubes- 

 cence. Antennal scape one-half as wide as long, widest across the 

 middle; pedicel as long as the first three funicle joints combined; first 

 funicle joint a little wider than long, following three of the same length 

 as the first but increasingly wider, the fifth about three-fourths longer 

 again than the preceding joints, the sixth a little shorter than the fifth 

 and fully twice as wide as the first; club subquadrate, about one-fourth 

 longer than wide, very bluntly rounded or subtruncate at apex, nearly 

 one- third wider than the last funicle joint and nearly as long as the 

 last four preceding joints combmed. Wings with a narrow, curved 

 band of more transparent cilia at end of stigmal vein, which becomes 

 obsolete on the anterior margin of disk; oblique hairless streak reach- 

 ing from the stigmal vein about two-thirds of the way across the disk, 

 and without a distinct cut-off portion. Length, 0.9 to 1.3 mm. 



Front, vertex, and mesonotum bright orange yellow; face, cheeks, 

 occiput, and underparts pale yellow; concealed part of the pronotum, 

 a spot on each side of the metanotum and propodeum situated partly 

 on both, and the dorsum of the abdomen brown or blackish brown, the 

 lateral margins of the latter from base to apex yellow; collar of prono-
