Psylla ribis n. sp. 



Psylla ribis Riley, MS. is a species existing numerously in 

 collections under its manuscript name. The wing (Fig. 392) is 

 immaculate and the vein and stigma rather heavy. The head 

 (Fig. 407) is with prominent eyes, moderately long antennas 

 and the cones subequal in length to the third antennal segment. 

 The caudal segment of female (Fig. 430) is thick at hase and 

 about equal in length to the other abdominal segments. The 

 upper plate is straight along dorsal line and is much longer 

 than the lower plate. The male forceps (Fig. 417) are erect 

 and simple with hairs very short, sparse and inconspicuous. 

 There seem to be no food plant records available but the name 

 is suggestive.

Psylla brevistigmata n. sp. 



Two specimens in the Cornell collection which bears data 

 "Alta Meadows Seq. Nat. Park, Cal. 19 July 1907. 9,000 ft, 

 J. C. Bradley," seem distinctive enough to describe as new. The 

 Cauda (Fig. 427) is about the length of two preceding segments. 

 The upper plate is thickly armed with short stout conical setulse 

 and scattered with a few long setae. The facial cones are 

 swollen at base and very divergent with rounded tips. Fig. 413. 

 The broad wings are pale with pale shading (not heavy) along 

 tips of veins. The stigma is broad* at proximal edge but narrows 

 suddenly and acutely as is shown in Fig. 399. Me. 1339 Sub 31. 



Psylla hartigii Flor? 



A species common on birch (Betula populifolia ) in the vicin- 

 ity of Orono comes too near to hartigii Flor as characterized 

 by Sulc (1910) to descibe as new. Me. 1340 Sub i comprised
