[113] Report of the State Entomologist. 255 



Mr. Buckton has given but few items relating to the life-history of 

 this species. He states that two swarms occur in the year with a 

 certain interval, one in June and the other in October. During the 

 latter period the male makes its appearance, which he had taken under 

 the leaves of the garden cherry in company with oviparous females. 

 Mr. Walker had taken the latter on October thirty-first. 



Description. 

 The careful descrij^tion given of the insect in its several stages, 

 leaves but little to desire. For those who have not convenient access 

 to the first report of Dr. Fitch, we condense from it, as follows : 



The LARV^ when newly born are about 0.03 long, of a dull white 

 or pale yellow color, with transparent and colorless legs and antennae. 

 They are oblong-oval in form, with the opposite sides of their bodies 

 parallel, and their transparent or slighly dusky nectaries not reaching 

 to the tip. Later, they become broader across the abdomen and 

 deeper yellow, with the tijDS of the antenna; and the feet dusky and 

 the nectaries black. After molting they change to dull reddish-brown 

 or chestnut colored, with black heads. The legs, antennae, and nec- 

 taries are whitish transparent. 



The WINGLESS FEMALES are 0.05 long, broadly egg-shaped, black and 

 shining, with a tail slightly projecting, nectaries black and reaching 

 to or beyond the tip; the antennse are shorter than the body and 

 whitish, their two short basal joints and the apical half, black; the 

 beak whitish, black-tipped; the legs white, with the feet, tips of the 

 shanks, and commonly the thighs, at least of the hind legs, except at 

 their base, black. [Cauda long and black — Buckton.] 



The pup^ are 0.06 in length, resembling the wingless females in 

 color and the larvae in form, but may be known by the rudiments of 

 wings like vesicular scales of a white or pale green color; the nectaries 

 equal the tip which has no tail-like appendage. 



The WINGED FEMALES are 0.05 long, and 0.20 across the wings; 

 of a deep black and sliining color; abdomen nearly twice as broad 

 as the thorax, egg-shaped, with an acute apex having a short 

 conical tail-like appendage, the nectaries reaching to its base; 

 antennae black, and about three-fourths the length of the body; beak 

 black or dusty with a black tip; the legs black with the shanks, except 

 at their tips and the basal half of the thighs, white. The wings are 

 transparent, their bases, outer margins and rib-vein, white, the remain- 

 ing veins blackish with their bases pale; the stigma opaque, dull white 

 with black mai'gins.
