also, that the type in the Hulst collection is not a female, but 

 a male, the antennae of which are broken off; but sufficient 

 of the segments are retained to show the long pectinations. 



In the course of the study of this species I was at first in- 

 clined to regard both it and haydenata as one species, and 

 neither as belonging to Alcis, for, under the latter, Hulst had 

 two males, neither of which possessed the hair pencil on the 

 hind tibia characteristic of that genus. They also had the 

 same umber-colored wings, and the dorsal tufting of the ab- 

 domen ascribed to umbripennis was the only structure which 

 separated them. This abdomen of the type appeared to be 

 that of a female, and Professor Smith, to whom the specimen 

 was shown, corroborated my opinion at once and also called 

 my attention to the fact that the body belonged to some other 

 insect. I afterward detached the body to demonstrate this 

 point and found positive evidence of its having been glued 

 on. This was done very neatly, as may be inferred when 

 we consider that it passed through the hands of Hulst, Dyar, 

 Pearsall and myself without any of us suspecting the truth. 



After these .two forms were combined I at first supposed that 

 haydenata had no hair pencil, but specimens in my own col- 

 lection showed this structure plainly; so the question arose as 

 to which species Packard's types belong. These types are 

 females, but judging from his description, "uniformly pale- 

 reddish ash-gray," I do not think there can be any doubt but 

 that he had the form with the hair pencil in the male. There 

 are three male specimens of umbripennis before me, and none 

 have the antennae entire ; but I assume that they have a simple 

 apex. Thus, with the abdominal characters of Somatolophia 

 eliminated, our species rests very comfortably in Selidosema. 



Cymatophora festa Hulst. 



Another conclusion of Dr. Dyar's is that "the single 9 type 

 [of Cymatophora festa'] is Deilinea pulveraria Hulst," and 

 he adds : "The name festa has priority, but should be referred 

 to Deilinea." Now, how Dr. Dyar came to say this I cannot 

 even conjecture. The insects are so very different that the 

 statement led Mr. Taylor to say, as he did of the former, that 

 the specimen at New Brunswick cannot be the true type. That
