This species was hrst recoj^nized from an isolated female specimen taken 

 at Ithaca, btU in the absence of lun"oi)ean material for comparison the writer 

 hesitated to publish the record. Tliorough collectini^' on the same clump ol 

 alders at Ithaca, in iij2(), failed to jjritduce additional si)ecimens. I )urin,L;- the 

 month of .Xu.i^ust the writer made a collectin<;- trip along the north shore of 

 Lake v^uperior, having in mind to search for Psallus alnicola on alders in that 

 region. The effort was rewarded when the species was found breecling on 

 Ahiits riigosa at the mouth of Leaver Creek, I'eaver Ikiy, .Minnesota, where 

 that small stream empties into Lake Stiperior. .\ large series of nymphs and 

 adults were taken, but all from one grou}) of alders which grew at the waters 

 edge. Specimens were fotmd only on branches which received little direct 

 sunlight, and chiefl}' on the tender growth at the centre of each bush. This 

 rec[uirement of the species indicates that it can breed onlv under \erv favorrd)le 

 conditions of humidity and temperature. 



Xymphs of the fifth instar are chiefly red, the wing-pads, j)ronotal disk, 

 antennae, and legs dusky, apices of wing-pads darker; wing-pads, pronot;d 

 disk, and dorsal surface of head thicklv dotted with small fuscous points and 

 reddish; tibial spines dark, arising from consj)icuous black spots; femora dotted 

 with red on ventrrd surface, a few black points apically, a pair of larger spots 

 on anterior margin and a second pair on the ])osterior margin near apex.
