pubescence. Antennae longer than in allied species, the funicle 

 joints and club frequently not collapsing after death; scape about 

 twice as long as wide or a little narrower, widest at or beyond the 

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

 funicle joints of nearly equal length with the fifth and sometimes the 

 sixth slightly longer, the fh'st tlii'ee hardly increasing in width and a 

 little wider than long, last three increasing in width so that the sixth 

 is about twice as wide as the fii"st joint, the fourth and sixth and 

 sometimes the fifth wider than long; club subrectangular, truncate 

 at apex, no wider than the preceding joint and as long as the last thi*ee 

 funicle joints combined or a Httle more, or if collapsing more rounded 

 at apex and wider than the last funicle joint. Wings as in A. rileyi 

 but the transparent band of cilia may be incomplete also on the 

 lower margin of disk. Length, 1.2 to 1.4 mm. 



Front, vertex, and mesonotum dark orange yeUow, with dusky 

 shadings on the scutellum and a narrow, transverse, blackish fine on 

 each side of scutum in the type, but frequently without dusky or 

 blackish markings and rarely much brighter orange yellow in color; 

 center of occiput, concealed part of pronotum, the metanotum, 

 propodeum and dorsum of abdomen black or blackish, the latter 

 with the sides behind the vibrissae shading into dusky yellowish or 

 whitish, sometimes more distinctly so; face, cheeks and underparts 

 pale yellowish, with venter of abdomen dusky whitish; collar of 

 pronotum and tegulae wliitish with the usual browTi markings. 

 Antennal scape black with the base, apex, and line on upper margin 

 narrowly yellowish white; basal half of pedicel, fii'st two funicle 

 joints and club black; rest of pedicel and funicle yellowish wliite, 

 with the third funicle joint sometimes dusky. Legs pale yellowish; 

 the anterior femora with a brown spot near apex, the hmd femora 

 with an obscure streak of brown on outer surface; front tibiae with 

 tliree distinct brown annuli, the third one at apex, middle and hind 

 tibiae with two annuli and a brown spot at the Imee joint; last joint 

 of the tarsi tipped with blackish. Wings with faint cihary banding 

 usually as in A. rileyi; the veins pale brownish. 



Hale. — Front and vertex one-half longer again than w^ide; ocelli 

 nearly in an equilateral trituigle, the space between posterior pair 

 shghtly greater than distance from either to the anterior ocellus; 

 eyes more pubescent than in the female. Antennae nearly as in the 

 female except that the scape is much narrower or nearly four times 

 longer than wide with the lower margin gently rounded. Length, 

 1.25 mm. 



Coloration as in the female except that the sides of abdomen 

 behind the vibrissae are narrowly redchsh; and the scape of antemiae 

 black on outer surface with the base, apex and a narrow line on the 

 upper margin yellow, entirely yellow on inner face except a black
