PSYI.LID note;s. 223 



2 females collected from birch June 15, 191 1; Lot 1340 Sub 2 

 comprised 4 males and 20 females collected from birch July i, 

 191 1 ; Lot 1340 Sub 7 was a collection of 2 females taken with 

 P. striata on birch June 25, 1910. 



The antenna is conspicuously shorter than in galeaformis; 

 and the wings are yellow. The caudal segment of female is 

 much like galeaformis except for the constant downward curve 

 of the long upper plate. ^ Figs. 394, 408, 423, 429, 432, and 433, 

 sufficiently characterize this species to prevent its confusion 

 with other birch psyllids in this country. The nymphs were not 

 taken.

 Psylla cerasi n. sp. 



A species new to this country and for which I can find no 

 place in European records, was taken on 'September 14, 191 1, at 

 Stillwater, Me., on wild cherry. Psyllid eggs, probably of this 

 species were found on the same date tucked between leaf bud 

 and twig of the same little tree. 



This brilliant species had dorsal head and thorax rosy, dorsal 

 abdomen almost vermillion, a black spot on dorsum of ist 

 abdominal segment, 5 vivid black transverse bands across the 

 abdominal dorsum, the last coming just cephalad the genital 

 segment. Antennal joints 1, II, III rosy, rest black. Eyes 

 bright black and bulging to width of thorax or slightly more. 

 Wings clear and a little brownish. Ventral body pale. 



A female distended with eggs had a total length, exclusive of 

 wings and antennae, of 3.8 mm. The wing (Fig. 400) with M 

 and Rs approximating to give a pinched appearance. Wing 

 without stigma. Head (Fig. 412) with large triangular facial 

 cones rather acute at tip. Antennal length more than 2 1-2 times 

 the breadth of head. The caudal segment (Fig. 431) with upper 

 plate armed with large short blunt setulae which give it a dis- 

 tinctly noduled appearance. Me. 1341 Sub 4. 



Psylla coryli n. sp. 



A species under the manuscript name of Psylla coryli Riley, 

 MS. is sufficiently characterized by distinct large tooth-like 

 projections on the inner side of the male forceps (Fig. 419) to
