208 entomological news. [June, 'o6 



prothorax. Eyes large, their posterior tubercle highly developed, each 

 bearing three ocelli. The two ocelli on top of the head are placed close 

 to the anterior edge of the eyes, while the anterior one is situated on the 

 under side of the head. 



Rostrum long, reaching to the abdomen. Prothorax broader than long 

 and slightly broadest posteriorly, provided with a few lateral hairs on 

 each side. 



Abdomen about one-half the length of the body, its lateral edges quite 

 straight, and broadest near the region of the nectaries, the terminal end 

 broadly triangular, provided with sparse and fine hairs, which are still 

 more numerous along the sides and on the last segment. 



Tail short and broadly arcuate, bearing a small triangular projection at 

 the middle of the external margin, its two sides being quite sharply ser- 

 rate ; each side bearing apparently four bristles, with a few smaller ones 

 on its surface. The last segment is broadly semi-circular, and bears along 

 its edge quite a number of still longer and stouter curved bristles. 



Nectaries very long, almost as long as the whole insect, cylindrical, 

 straight and slightly curved outwards toward the apex, and covered pro- 

 fusely with long and fine divaricating hairs or bristles. 



Legs rather long and slender, provided on femora and tibiae with stiff 

 hairs. Front wings much longer than the entire body, the venation re- 

 sembling more or less that of Aphis and Callipterus. The first two dis- 

 coidals are distant at base and about seven times as widely separated at 

 the apex ; the first vein is almost straight, whereas the terminal one-third 

 of the second vein is much curved toward the base of the wing ; the third 

 discoidal with its two forks resembles somewhat that of Callipterus ; the 

 basal half or less of this vein, or the stem of it, is obliterated ; the stigma 

 is long, narrow, parallel ; stigmal vein gently curved and terminating at 

 the apex of the wing. The hind wings are much shorter and much nar- 

 rower than the front wings and have the usual oblique veins, which are 

 quite straight, far apart at base, and more than twice as far apart at apex. 



The pupae have the body and legs much more hairy ; the hairs of these 

 parts are longer and stouter than in the migrant, while those of the tail 

 and end of the body are shorter and finer. The upper side of the abdo- 

 men is marked with numerous pale brown spots of varying size, followed 

 by a brown band, the latter divided at the middle, and itself followed by 

 a very large spot between and touching the nectaries. In other respects, 

 the pupae resemble the migrant, excepting that the nectaries are not 

 quite one-half the length of the body, and are also comparatively stouter 

 and slightly tapering toward both ends. The triangular point of the tail 

 is also somewhat longer. 



Apterous Female. — Body pyriform, the head, pro- and mesothorax 

 being narrowest, the rest of the body broadly oval. Front of head 

 straight, or almost so, and destitute of frontal tubercles. Eyes of the 

 usual size, their posterior tubercle prominent and furnished with three 

 large and rather globular ocelli. Antennae about two-thirds the length
