Aphalara veasiei n. sp. 



A green bodied psyllid with amber yellow wings was collected 

 in great numbers in the vicinity of Orono. The vegetation 

 swept by the collecting net was Solidago and Myrica aspleni- ^ 

 folia L. (sweet fern) in one locality and grass, Solidago and 

 other growth in a second locality. The nymphs were not found 

 and the host plant is as yet unknown. The species was most 

 abundant in late June and early July, though a few specimens 

 were taken in the same localities July 27. 



Head. The head is broader than the prothorax and nearly 

 twice as broad as long when viewed from the dorsal aspect. 

 The cephalic aspect of the head (Fig. 19) shows 2 approximate 

 but separated quadrate epicranial plates (ep). These are raised 

 and very distinct. At the latero-caudal angles of these plates are 

 situated the posterior ocelli. In a triangular enlargement of 

 the suture between the 2 epicranial plates at their mediocephalic 

 angles is situated the front ocellus (fo). The ventral aspect of 

 the head (fig. 20) shows the frontal cones (fc), ovoid in outline 

 placed one on each side the frons (fr). The frons is also rather 

 ovoid and about the size of the frontal cones. The distal end of 

 the frons projects caudad. The antennal sockets are about on a 

 line with the front ocellus and are situated in an angle caudad 

 the frontal cones and mesad the compound eyes. The antenna, 

 if extended backward, would reach a little caudad the base of 

 the first pair of wings, their length being about 0.8 mm. There 

 are 10 joints. Ill is longer than any other. IV to VIII are 

 subequal, each being about half the length of III. IX and X are 

 shorter and broader than the preceding joints. X with two stout 

 terminal diverging spines, one of which is slightly longer than 

 the other. Joints IV to VIII inclusive each bear a single distal, 

 laterally placed, circular sensorium fringed with delicate hairs. 

 These resemble somewhat the terminal sensorium of the fifth 

 and sixth antennal joints of the aphids. The antenna is not 

 setose. 



Wings. The wings are amber yellow in tone and are with or 

 without pale brown flecks which when present give the distal 

 portion of the wings a mottled appearance. The variation in 

 the flecking of the wings is perhaps due to differences in the age 

 of the individuals, as psyllid s are uniformly paler when young 

 than the more highly colored individuals. The distal end of the
