CORRESPONDENCE. 



THE GENUS QUADRINA. 



Dear Sir, — Mr. Grote, in the current vol. of the Can. Ent., p. 40, 

 takes exception to my note on this genus, and says my " remarks as to 

 Hemileiica are uncalled for." The only thing I said in the note com- 

 mented on by Mr. Grote, in regard to Hemileuca, was : " In Mr. Grote's 

 Catalogue of 1882, Qicadrina diazoma is placed in the ' Hemileucini ' and 

 is associated with Hemileuca, Hyperchiria and Coloradia, which are all 

 typical Bo/nbycids." This is the fact, as a simple reference to the list will 

 prove, and I cannot see in what manner the remark was uncalled for. I 

 knew of all that Mr. Grote had written on the subject, and simply 

 assumed, as I had a right to do, that Mr. Grote had changed his views as 

 to the position of the genus, and that his latest view was expressed in the 

 list. That the location was due to a printer's error I could not know. 

 However, its position in the Ceratoca^npidce is equally unnatural. As 

 that group stands in Mr. Grote's list it is a perfectly natural and sharply 

 limited one, all the members of which have in the male two branches to 

 each side of each joint of the antennae, which are moderately long, and 

 the pectinations do not extend to the tip. In Quadrina, on the contrary, 

 the joints are extremely short, the pectinations extend to the tip,, and are 

 very long ; there is only a smgle branch to each side of each joint. If 

 the specimen is a female, as Mr. Grote says, the antennal structure is 

 unique and out of harmony with that of the other Ceratocampidce. It 

 would break up the group entirely to admit such a form in it. But I be- 

 lieve the specimen to be a male. I do not find in my notes on the species 

 any mention of the sex, but my recollection is that it was a male The 

 species belongs most nearly where Mr. Grote first put it. I quote my 

 own remark — " nearly related to Glover ia.^' 



As to the Hemileucini, I have taken from it the genera Hyperchiria 

 and Coloradia and placed them in the Sattirniidce, in a recent revision of 

 that Group in the Proc. Nat. Mus., ix., pp. 414-437.
