Length .'^.'2 mm., width of the abdomen 1.8 mm. Bodij — Decidedly wide and 

 flat, covered with long fine light hairs, much larger than the winged individuals, 

 naked if taken underground and ])ruinose if above. Prevailing color — Grayish to 

 amber brown with darker brown markings, which may also be nearly black. A 

 thin coating of white jiowder gives it the gray color. The ground color may 

 vary from a light yellow, jjink. or dark amber. Head — Nearly traiiezoid;il in 

 shape with the base and front jjarallel, wide and flat between the antenna?, with 

 very short, indistinct frontal tubercles, reddish or yellowish brown to gray, with 

 two darker- s])ots near the base. Ei/es — Small, with distinct tubercles, red. An- 

 tennae — (Figure 'iSi, (] and 7). Not half .-is long as the body, on indistinct 

 tubercles, hairy-hairs on tubercles; articles I and II concolorous with head. III 

 and IV^ trans))arently yellow to whitish, \' dusky yellow with dark amber a))ical 

 one-half, VI dark .'imber brown throughout. Lengths of the articles: I, 0.09

 corres))ond well with those of the winged females. Rostrum — Reaches beyond 

 the third coxa>, nearly to the middle of the abdomen, whitish with dark markings 

 at the extreme ti)3 only. Thorax and Abdomen — Ground color varying from 

 whitish yellow, to rich yellow, amber, reddish brown to gray with distinct darker 

 markings wliicii may be rich dark yellow, brown or nearly black. These mark- 

 ings, usually darker shades of the ground color, are (juite variable in extent. The
