stilus Lec.,* which had eaten holes through the dorsum, usually 

 in the anterior portion, and devoured all but the exterior por- 

 tion or shell. Material collected at New Haven August 13th 

 was rather highly parasitized by a minute chalcidid of the fam- 

 ily Aphelininae, kindly determined for me by Dr. L. O. Howard 

 as Encarsia hit cola How. 



Named from the genus of plants upon which it was found. 



Aleyrodes waldeni sp. now 



Egg. — Unknown. 



Larva. — Yellowish white in color, oval, about five-eighths as broad 

 as long. Dorsum flat or nearly so, with a row of spines or wax 

 tubes around the margin. No tubes or other wax secretion on dorsal 

 surface. 



Pupa. — Length about .67 mm. ; breadth about .40 mm. Shape oval, 

 broadly rounded at ends, but more or less constricted and modified 

 locally by the plant hairs surrounding it; well raised from the sur- 

 face of the leaf by a vertically striated wall of wax about 153 /* high. 

 Color of pupa light greenish yellow, empty pupa skins white, vasiform 

 orifice darker and yellowish. Dorsum rather strongly convex, fur- 

 rowed transversely according to adult segmentation. Marginal area 

 somewhat wrinkled or corrugated. Margin finely crenulate. Fringed 

 with a submarginal row of down-curved glassy wax rods about 10 f*- 

 long. Just inside the margin is a row of stouter, more or less curved, 

 wax rods, mostly standing upright. Other rods are borne upon the dor- 

 sum, the longest being as long as half the breadth of the insect, and are 

 arranged as follows: Four at cephalic extremity; two half way the 

 length of the thoracic region, one on each side; one pair just behind 

 the last pair, between the margins and ends of the first transverse 

 furrow ; one pair on last thoracic segment ; two pairs near the margin 

 at base of the abdominal region ; one pair on each of four of the 

 abdominal segments, one rod on each side, and placed near the ends 

 of the furrows of segmentation ; two at anal extremity. These rods 

 are very brittle, and are altogether wanting in most of the dried 

 specimens studied; in the mounted material the location of these rods 

 can be made out, yet there seems to be considerable variation in the 

 number and arrangement. 



Vasiform orifice subtriangular, with angles rounded and sides bulg- 

 ing; about seven-eighths as broad as long. Operculum nearly semi- 

 circular or slightly reniform, two-thirds as long as broad, and reach- 

 ing half the length of the orifice. 



Lingula spatulate, terminating in a seven-lobed apex, the terminal
