WOOLLY .'M'HIDS OF THE SLM. 261 



The apterous males are but 0.55 mm. long and their bodies are 

 slender. Their antennje and legs are relatively much longer 

 than those of the female. Antennae are 5-jointed. Mature 

 male without beak, this being lost at molt. Described from 

 specimens taken September 23, 1908. Maine collection number, 

 89-08. 



Antennal drawings of different forms are given here for 

 comparison with the other species. 



Fig. 119. The antenna of the stem mother of rileyi is dis- 

 tinguished at once from those of the curl and rosette dwellers 

 by the difference in length, it being much shorter in this species. 

 It is normally a 5-jointed structure but there is frequently a 

 clear spot in III as shown in this figure which seems to be a 

 vestigial indication of another joint. (52-13). 



Fig. 120. Evidently a part at least of the second generation 

 become winged as winged forms are present by the middle of 

 June at which time the stem mother is still actively producing 

 nymphs. The antenna of the pupa is given in this figure. 

 (7-08). It is characterized by a rather short bulged IV. 



Fig. 121. The antenna of the spring winged generation is 

 characterized by having wider spaces between the annulations 

 on III than is usual for the curl and rosette dwellers, and with 

 less symmetry as to the antennal grooves. Annulations are com-
