584 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 50. 



Male. Front and vertex no longer than wide; ocelli in a right- 

 angled triangle, the posterior pair one-half their own diameter from 

 the eye margin. Antennal scape much narrower than in the female, 

 only one-fourth as wide as long; pedicel a little shorter than the 

 first funicle joint; funicle cylindrical, barely increasing in width 

 distad, the first three joints subequal in length and distinctly longer 

 than wide, the last three joints slightly shorter, but still longer than 

 wide unless they collapse or flatten on drying, when the fifth and 

 sixth are about as wide as long; club elongate oval, rather pointed 

 at apex, barely wider than the last funicle joint and as long as the 

 last two and one-half of the fourth joint of the funicle. Length: 

 0.75 to 1.0 mm. 



Coloration similar to the female, but the mesonotum is pure dull 

 black with the yellow on the sides less extensive and more con- 

 trasting; the black of occiput may encroach .on the vertex to the 

 ocellar region; face entirely pale yellowish. The antenna! scape 

 and apex of pedicel yellowish white; base of pedicel, an oval spot 

 on inner face of scape, and upper margin of the outer face except 

 at base and apex black; the funicle and club uniformly pale brown. 



Described from seventeen females, one male (type, allotype, and 

 paratypes a to p) reared from Kermes essigii King on Quercus agrifolia, 

 Pasadena, California, August 7, 1912 (P. II. Timberlake), and four 

 females, two males (paratypes q to v) reared from Kermes galliformis 

 Kiley, Murray, Utah, September 16-21, 1914 (P. H. Timberlake). 



The paratypes from Murray, Utah, differ slightly from the Pasa- 

 dena specimens in having the mesonotum more yellowish with less 

 black, and in having the last funicle joints as long as wide. The 

 male from Pasadena is poorly preserved, so that a comparison in 

 this sex is not possible, but the coloration seems nearly identical.

4. AENASIOIDEA LATISCAPUS Girault. 

 Aenasioidea latiscapus GIRAULT, Can. Ent., vol. 43, 1911, p. 173. 



Female. Front and vertex about one-half longer again than 

 wide; ocelli in an equilateral triangle, the posterior pair about 

 their own diameter from the eye margin and a little farther removed 

 from the occipital rim; antennal scrobes rather narrow and deep, 

 uniting above. Antennal scape one-half as wide as long, widest 

 across the middle; pedicel nearly as long as the first two funicle 

 joints combined; funicle cylindrical but slightly increasing in width 

 distad, the first four joints distinctly longer than wide, the last two 

 hardly so, the sixth being as wide as long, the third joint longest, 

 the fourth slightly shorter, other four joints subequal and noticeably 

 shorter; club oval, as long as the last three funicle joints combined 

 and nearly twice as wide as the preceding joint. Wings uniformly
