 Aphycus lecanii King (not Howard), Can. Ent., vol. 31, 1899, p. 140. 



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

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

 eter from the eye margin; antennal scobes broad and shallow, the 

 facial prominence not much elevated; eyes with a sparse, fine pubes- 

 cence. Antennal scape about two and one-third times as long as 

 wide, widest just beyond the middle; pedicel a trifle longer than the 

 first two funicle joints combined; first three funicle joints subequal 

 in length, the fourth and sixth shghtly longer, and the fifth still 

 more so, the first two and the fifth aljout as long as wide, the others 

 a little wider than long; club oval, l)luntly rounded at both ends, 

 one-fourth wider than last funicle joint and as long as the three 

 preceding joints combined. Disk of wing uniformly cdiated, but 

 the cilia at base of wing beneath submarginal vein are thinner, 

 weaker, and paler colored; oblique hairless streak not reaching 

 the posterior margin of wing. Length, 0.8 to 1.25 mm. 



Front, vertex, upper rim of occiput, and entire mesonotum bright 

 orange yellow; face, cheeks, most of occiput, collar of the prono- 

 tum, tegulae and underparts creamy white, with the usual dots on 

 collar and tegulae and the apical half of venter brown; concealed 

 part of pronotum, the metanotum, propodeum, and dorsum of abdo- 

 men brown, with the basal corners of the latter creamy white. 

 Antennal scape black, with the upper margin white, broadly on the 

 mner face, more narrowly on the outer surface; pedicel except at 

 tip, first two funicle joints, base and under side of the third joint 

 and club black, remainder of antenna white. Legs concolorous with 

 underparts, the tibiae not marked, tlie tarsi more yellowish, with the 

 tip of the last joint blackish. Wings with a large, brownish spot 

 moderately distinct beneath stigmal vein, sharply limited basally 

 by the oblique hairless streak, entirely tegumentary in nature and 

 not due to the ciliation. 



Male. — Head much shrunken in all available specimens, but the 

 front and vertex apparently about as wide as long; ocelli in an 

 equilateral triangle, the posterior pair about their own diameter 

 from the eye margin. Antennal scape a little shorter and narrower 

 than in the female; pedicel a little wider than the first funicle joint 

 and no longer; funicle joints all of about the same length, the last 

 three slightly wider, but longer than wide, the first three considerably 

 longer than wide, all provided with a moderately long pubescence;
