forms seem to have well marked differences in habitat but not in 

 host plant. Wanakena, July 29, 1920, in deep wood on fern 

 associations. 



Typhlocyba querci (Fitch). 



This species was described from oak, but it has a wide variety 

 of host plants and in this region it must survive entirely on other 

 species as the oaks are absent. It is sutficiently abundant to cause 

 a definite drain upon the trees aifected and does not seem to have 

 any close limitations and habitat as it may be taken at various 

 levels on birch and other trees. Cranberiy Lake, eTulv 25, 1917 ; 

 July 10, 1920. Wanakena, Aug. 1-7, 1917'; July 15, 29, 1920. 



Typhlocyba querci var. bifasciata Gillette and Baker. 



This variety, like the previous species, appears to have a wide 

 range of food plants but has been noted as even more abundant 

 than the species above. Cranberrv Lake, Aug. 1, 1919 ; July 2, 

 25, 1920 (adult) ; Aug. 13, 1920. "Wanakena, Aug. 1-7, 1917". 



Typhlocyba lethierryi Edwards. 



This has been taken only twice and is pi-oliably quite rare. 

 Cranberry Lake, Barber Point, Aug. 5, 1920. Wanakena, July 29, 

 1920. One specimen (Wanakena), probably to be placed here, 

 has distinct black dot on inner cross nervure. 



Typhlocyba tenerrima (Herrich-Schaeffer). 



Very rare, as only a very few specimens have been found, but 

 these have been collected in the woodland associations, generally 

 where there is considerable moisture. Cranberrv Lake, July 25, 

 1917; July 12, 1920. Wanakena, Aug. 1-7, 1917. 



Typhlocyba rosae (Linnaeus). 



This is a very abundant species on roses throughout the country ; 

 it occurs in this region on different forest trees but never in great 

 abundance. The species is apparently capable of living in varied 

 conditions although limited to thickets or woodlands where it has 

 both shade and moisture. Barber Point, Aug. 13, 1920. Plains, 

 Aug. 3, 1920. 



Typhlocyba conies var. comes (Say). 



Taken only rarely and then from trees cJong tote-roads. Barber 

 Point, Aug. 5, 1920. 



Typhlocyba comes (Say) var. 

 Cranberry Lake, July 18, 1917.
