23. APHYCUS CLAVIGER, new species. 

 Figs. 25, 44. 



Female. Front and vertex a little over twice as long as wide; 

 ocelli in an acute-angled triangle, the posterior pair about one-fourth 

 their own diameter from the eye margin; eyes with a fine, short 

 pubescence. Antennal scape about two and one-half times longer 

 than wide, widest just beyond the middle and a little narrower than 

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

 funicle joints two to five of equal length, the first a trifle longer and 

 the sixth but little longer than the first, all increasing gradually in 

 width so that the sixth is nearly twice as wide as the first, and all 

 but the first wider than long; club oval, rounded at apex, nearly 

 twice as wide as the last funicle joint and a little longer than the 

 five preceding joints combined. Wings uniformly ciliated; oblique 

 hairless streak narrowed above and almost obliterated on the lower 

 half, the cut-off portion being very small and widely separated both 

 from the upper portion and from the posterior margin of wing. 

 Length, 0.8 mm. 



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

 entire underparts sordid pale yellowish; collar of pronotum and tegu- 

 lae whitish, the former with the blackish dot on each corner connect- 

 ing with the blackish coloration on the concealed part of the prono- 

 tum, the tegulae unmarked; concealed part of occiput and pronotum 

 blackish brown; metanotum, propodeum, and dorsum of abdomen 

 brown, the latter with the lateral margins yellowish, especially behind 

 the vibrissae. Antennal scape black with the base and apex yellow- 

 ish white; basal half of pedicel black, the apex orange yellow; first 

 three funicle joints blackish brown, the last three orange yellow; club 

 black, shading into orange yellow on the apical half. Legs pale 

 yellowish, with the last joint of the tarsi brownish. Wings hyaline, 

 the veins pale yellowish. 



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

 ocelli in an equilateral triangle, the posterior pair about one-fourth 

 then 1 own diameter from the eye margin. Antennal scape hardly 

 expanded below, about three times as long as wide; pedicel as long 

 as the first four funicle joints combined; first five funicle joints sub- 

 equal in length, the sixth considerably longer, all increasing slightly 

 in width so that the sixth is about one-third wider again than the 

 first and all wider than long; club oval, rather pointed at apex, 

 about one-third wider than the preceding joint and nearly as long as 

 the funicle. Wings have the oblique hairless streak more prominent 

 than in the female, the cut-off portion being of usual size but not 

 reaching the posterior margin of wing. Length, 0.7 mm.
