396 THE CANADIAN ENTOMOLOGIST. 



two broods, as in a series of ioo specimens before me I have three speci- 

 mens dating May 22-27, a number July 10-22, more from Aug. 1 to 20, 

 and a few from Sept. 1-5. Separating them into groups, according to 

 months, I find great variation in size, and ochre colouring in the extra- 

 discal line ; the specimens range from 13 mm. to 20 mm. The ochreous 

 colouring does not seem to be confined to those of any one month, but 

 the September specimens perhaps are a trifle more highly coloured. It 

 was from two small-sized males that I drew up my description of E. 

 Grossbcckiata, ntbulosa and miseru/ata, males not being known at that 

 time. Mr. Chas. R. Eby, of Washington, D. C, has kindly furnished me 

 with a large series collected at East River, Conn., and has bred the species 

 on Joe Pye Weed, which is, I believe, a new food-plant for it. Mr. 

 Dimmock, of Springfield, Mass., gave me specimens which he had bred 

 on Aster, and Mr. Pearsall in his article mentions that Patton reared 

 miseru/ata on Composite flowers. Packard in his Monograph, page 55, 

 gives the food-plant as juniper, but I believe he bred only the true 

 interruptofasciata on this, as he evidently did not know miseru/ata, 

 ('.rote, which, I believe, has "not so far been found on the juniper. In the 

 collection at Albany, N. Y., are two of Packard's male types of Eupithecia 

 interruptofasciata (in error), on which I wrote an article in the Can. Ent. 

 (Vol. XL, No. 7, page 246). One of the specimens, No. 1833, with 

 heavily-ciliated antennae, is the male of Eupithecia miseru/ata, Grote ; 

 the other male, No. 1833a, is Eupithecia cotifor mata, Pearsall, recently 

 described. This does not affect the standing of interruptofasciata, as I 

 retained the name on the female specimens in the Packard collection at 

 Cambridge, but it clears up the identity of the males at Albany, N. Y. 



Thus the species miseru/ata stands : 



Eupithecia miseru/ata, Grote (Proc. Ent. Soc. Philadelphia, 11,32, 1863). 

 = Syn. nebulosa, Hulst (Trans. Am. Ent. Soc, XXIII, 266, 1896). 

 = Syn. Grossbeckiata, Swett (Can. Ent., XXXIX, p. 378, 1907). 



Eupithecia miseru/ata, Grote, probably is labelled correctly in very 

 few collections, but is easily distinguished by the heavily-ciliated antennae. 

 Plate VIII, fig. 5, in Packard's Monograph is a very good figure of the 

 ochreous form which seems to come later in the season. The species 

 seems to be far more common in the South Atlantic States, but is com- 

 paratively local in Massachusetts, though common in Connecticut and 

 southward.
