REPORT OF THE STATE ENTOMOLOGIST I907 1 33 



Specimens in the State Herbarium from Fort Edward (Professor 

 Peck) as above, Catskill mountains (Peck) "club broader and 

 more abrupt," and Felt House, Lewis co. (Peck) labeled E. 

 f a g i n e u m. 



Collected at Normansville (Mr Gillett), Gravel pond near 

 Grafton, and Catskill. N.Y. 



Hagen's " E . f e r r u g i n e u m " is evidently a slip by con- 

 fusion with the old specitic name of the host. 



65^ E r i n e u m f a g i n e u m Link no. 32. 



Schweinitz '34, no. 2806 N.C., Pa. 



Placed by de Schweinitz (and by Persoon '22 : no. 16) in the 

 section with capitate trichomes. Described by Persoon from 

 Fag us sylvatica; his description seems more applicable to 

 the following than the preceding as he says : " in foliis . . . 

 magis versus marginem superiorem. Ab initio album." Loew, 

 however, (Vienna 1885) describes it as " ausnahmslos auf der 

 unteren seite der Blatter," (of F. s y 1 v a t i c a). I do not know 

 which form de Schweinitz had before him ; he docs not name the 

 host, but the latter is assumedly our native species. 



*66 A whitish or golden yellow to brown erineum on the upper 

 side of the leaf between or following the veins. Trichomes capi- 

 tate. Perhaps a form of no. 65. 



Garman '92, no. 19, fig. 5 N.H., Mich. 



Specimens from Blackhead mountain at 1850 feet in the Cats- 

 kills, from Catskill, and near Grafton. N.Y. 



This may be compared with the E r i n e a .n n e r v i s e q u u m 

 of Persoon '22, no. 22, Loew '85, p.456, occurring on the European 

 species of beech. 



Fagus sylvatica (European beech) 

 67 A frosty, wdiite erineum in large patches on the under side of 

 the leaf. Trichomes spherically capitate. 



Jarvis '07, p.62, fourth sp., pl.B, fig. 4 Ont. 



This agrees closely with Loew's description of Erineum 

 f a g i n e u m [Verhandlung der k.k. zool.-bot. Gesellschaft in 

 Wien, 1885, p.456]; see under no. 651/. Probably identical with 

 our no. 65, and possibly Jarvis cited the exotic beech by an over- 

 sight, as he says it is " very common."
