[89] ON CARADEINA FLDICULARIA. 201 



XV. ON CARADRINA FIDICULARIA MORR. 



This species was described as Segetia fidicularia by Mr. 

 Morrison, in Proc. Bost. Soc. Nat. Hist., vol. xvii, p. 146. 

 In the Grote Check List (No. 456) this name is recorded as a 

 synonym of Caradrina fmultifera Walker. In vol. viii, p. 

 188 of the Canadian Entomologist, Mr. Grote refers the species 

 to the European C. cubicularis S. V., from a comparison made 

 by him, with a male example of the latter, noting as the 

 only difference between the American and the European forms, 

 that the latter has the common line beneath more extended, 

 and the hind wings white. 



With four examples of C. fidicularia before me (three in 

 nearly perfect condition), and two of cubicularis, I am com- 

 pelled to differ from the reference made by Mr. Grote. I note 

 the following points of difference, as my reasons for regarding 

 them as distinct. 



While in C. fidicularia the primaries are of a clear gray, in 

 cubicularis they are of a peculiar pale brownish shade, diffi- 

 cult to designate, bearing what might be called an amber tint. 

 In the former, the intranervular marginal black dots are more 

 conspicuous than in the latter, and its subterminal line is not 

 followed by whitish ; tha posterior transverse line is farther 

 removed from the reniform than in cubicularis. C. fidicu- 

 laria has a well marked discal dot, which the other has not. 

 The primaries of the American species are the broader. 



The secondaries of fidicularia are of a fuscous shade, increas- 

 ing in depth toward the margin ; in the other they are white, 

 with the end of the nervules and extreme margin tinted with 

 ochraceous. In the latter, no discal spot is seen from above, 

 while in the former it is quite conspicuous the heavily 

 marked dot of the lower surface showing in transparency. 



C. cubicularis is known to be a variable form, differing 

 greatly, according to Guenee, in size, depth of color, and 

 intensity of designs, having been described under the sev- 

 eral names of quadripunctata Fabr., segetum Esp., callisto
