 transverse rows. Pygidiuni dusky. 



APTEROTis vivrPAROiis FEMALE (Figure 247. C) 



Length of body 2.4 mm., width of abdomen 0.65 nnn. Body kmg aud 

 narrow, and in not a few the head and thorax are as wide as the abdomen, the 

 body sides being nearly parallel. The drawing shows the typical shape. 

 Prevniling color — Light yellowish-green w-ith small red spots on the entire 

 dorsum. Head — Rounded, wider than long but not as short as in the wnnged 

 individuals, hair between the antennae often capitate, yellow or light green 

 with several small red .spots bearing hairs on the dorsuuL Eyes — Nearly 

 globular, red. Antennae— {Figure 248, 2). Reaching nearly to the middle 

 of the mesothorax, imbricated, slightly hairy, coloration same as in winged 

 forms, five-articles; length of articles: I, 0.06 mm.; II, 0.7 mm.; Ill, 0.2 mm.; 

 IV, 0.1 mm. ; V, 0.12 mm. : total 0.55 mm. ; their comparative lengths about the 

 same as the articles of the winged female. Large oval sensorium on article 

 IV and the usual sensoria in the process of V. Rostrum — Reaching beyond 

 the third coxte, light green with dark tip. Prothorax — Narrow, nearly as long 

 as broad, apex narrower than head, widening .slightly towards the base, with 

 many small red spots, each bearing a single fine tuberculate hair, light yellow. 

 Mesothorax — Long and narrow, nearly as long as the width across the pos- 

 terior end, green with red spots and hairs on the dorsum. Metathorax — 

 Extremely short, not one-third as long as the mesothorax and a little wider, 

 with a distinct transverse row of red spots on dorsum and several spots near 

 the anterior margin, green. Abdomen — Green, nearly cylindrical, dorsum 

 covered with transverse rows of small red spots, each bearing a fine tuber- 

 culate hair. Some of these spots are very irregular and differ greatly in size, 

 while all may be very poorly arranged in rows and appear .scattered. La.st 

 abdominal segment and pygidiuni dusky, hairy. Ventral .surface ])alc green 

 with two rows of five red spot.s each (Figure 248, 6) near the margins at the 

 union of the segments. Anal and genital plates dusky. Cornicles — (Figure 

 248. 7, 8). Practically the same as those of the winged females. Legs— 

 Lengths the same as in the winged individuals, hairy, amber yellow to amber 

 brown throughout ; coxjc and bases of femora pale green ; tarsi amber brown. 

 Style — Obsolete. Pygidium — Dark, liairy. 



Hosts — First taken by the writer from cultivated Pine trees (Pinus 

 radiata Gord) Monterey Pines, which are growing on the i'omona College 

 Campus. The insects fire not in colonics but are scattered scjiaratcly over the 

 entire trees. They are usually to be found most plentiful on tlic terminals of 

 tlie branches and feed upon the needles, along which th(>y arc able to move 

 very rapidly. In moving they clasp around the needle with all Feet, but 

 particularly with the short front and the long hind legs. It is imijossible to
