240 THIRTIETH REPORT ON THE STATE MUSEUM. [128] 



The above description is inapplicable to the Hypena 

 Tiumuli of our collections ; it applies fully to Hypena scabra 

 Linn., and to no other species with which we are acquainted. 

 In H. scabra, the fore-wings are marbled with gray beyond 

 the middle" in H. humuli, not : "the two wavy blackish 

 lines, one near the middle, and the other near the outer hind 

 margin, are formed by little elevated black tufts ;" in humuli 

 these lines do not consist of elevated scales or tufts, even in 

 examples just emerged from pupae. The " two similar tufts 

 on the middle of the wing " of scabra, are replaced in humuli 

 by four. Of the former species, " the wings expand one inch 

 and a quarter ;" of the latter, no specimen of large numbers 

 under my observation, have equaled that expanse. 



From the above it seems evident that the description of 

 Harris was drawn from examples of H. scabra before him : 

 from the general resemblance of the two species, scabra 

 examples may have accidentally replaced those which he had 

 reared from the hop, and which he intended to describe. 



An earlier reference to the species is made by Harris in his 

 Catalogues of the Animals and Plants of Massachusetts^ 

 1835, page 74, where it is included among the Tineidse as 

 Crambus humuli. 



The description of "Hypena humuli" is also given in 

 the subsequent editions of Dr. Harris 1 Report.* 



In 1855, in the Transactions of the N. T. State Agricul- 

 tural Society, vol. xv, pp. 555-558, pi. 1 fig., 1, Dr. Fitch 

 describes and figures the moth obtained from the hop-vine 

 larvae as the Hypena humuli of Harris, in the event of its not 

 proving identical with the European H. rostralis L. This 

 being the first description of the species, the name of Dr. 

 Fitch will hereafter have to be associated with it. The above 

 is also to be found in the volume of the First and Second 

 Report on the Noxious Insects of New York, pp. 323-326, pi. 1, 

 fig. 1, printed in 1856. 



In the Annals of the Jjyceum of Natural History of New 

 York, ix, p. 311 (1870), Mr. Colernan T. Robinson describes a 

 form as Hypena evanidalis. This form proves to be the female 

 of H. humuli the sexes differing so much that for a long 

 time they were regarded as distinct species.
