resemble groups of ocelli. They are dark red. True ocelli are 

 not visible in the writer's specimens. The antennae are short, 

 scarcely reaching to the base of the prothorax; dusky; the entire 

 surface covered with very short spine-like hairs arranged in con- 

 centric rings, and a few longer hairs; 4-articled (in some speci- 

 mens there is an indication of a division in article III, making 5 

 articles). The lengths of the articles are approximately as follows: 

 I, 0.05 mm.; II, 0.04 mm.; Ill, 0.15 mm.; IV, 0.09 mm.; total, 

 0.33 mm. The sensoria are few, nearly circular and distributed as 

 follows: one large circular one near the tip of III and several 

 smaller ones in the process of IV (there is also usually a noticeably 

 clear semi-circular area, free from the small spines near the middle 

 of III which has the appearance of a sensorium, but which is evi- 

 dently not one). The thorax gradually widens from the head and 

 Is of the same general color as the abdomen. The abdomen Is 

 broadest at the middle or near the posterior end, marked with dark, 

 broken transverse bands on the dorsum. The cornicles are short, 

 scarcely extending above the surface of the abdomen, noticeably 

 wider at the base, dark, hairy, located near the posterior end on the 

 6th abdominal segment. In many specimens the writer was unable 

 to locate cornicles at all and is led to believe that they are not pres- 

 ent In all specimens. Dr. Cockerell mentions the absence of corni- 

 cles In specimens taken by him. The legs are short and rather frail- 

 looking for the size of the body, hairy and dusky. The cauda is 

 broadly rounded, dusky and quite hairy. 



Winged Oviparous Female 



(Fig. 6) 



The general color of the winged oviparous female Is dark olive- 

 green, with the muscle lobes, nearly all of the head, antennae, legs 

 and the markings on the dorsum of the abdomen dusky or black. 

 There Is a lateral mass of white cottony wax on either side of the 

 abdomen designated by the dark areas in the vicinity of the cornicles 

 shown In the drawing (Fig. 6) . The normal length ranges from 1.5 

 mm. to 1.8 mm. and the width from 0.6 mm. to 0.8 mm. The head
