182 PAPERS BY DR. B. CLEMENS. 



I received a specimen of the above insect some time since 

 from my esteemed friend Benj. D. Walsh, of Rock Island, 

 111., who was compelled to fix it to a strip of card for the 

 want of small pins. The specimen may have been injured in 

 its parts by this treatment, but I cannot discover any injury. 

 He likewise forwarded at the same time a specimen of the 

 case, which is earth-brown in colour and consists of silk, 

 granulated with particles of fine sand, and therefore the larva 

 could not have been a wood-miner, as Mr. Walsh at first 

 supposed. The larva is in all probability lichenivorous and 

 feeds in the portable case in which Mr. Walsh found it in the 

 fall. I sincerely hope the discoverer of the species will uot 

 fail to ascertain the natural history of the larva and put it on 

 record in the pages of the " Journal," for I know no one Avho 

 can do this more pleasantly and accurately. 



In his letter to me Mr. Walsh says: " The little moth 

 I sent you is certainly not a i wood-miner,' although it occurs 

 in the bark of shag-bark, hickories and other trees with scaly 

 bark. From finding the larva late in the fall and the winter 

 enclosed in its case in that situation, I had supposed that it 

 fed under the bark; but I ascertained in August and Sep- 

 tember that it was not there, and therefore conclude that it 

 merely retires there to become a pupa. I noticed an indi- 

 vidual apparently identical this winter attached to a pine- 

 board fence. There was not the least appearance of ' mining' 

 under the bark, by which I understand cutting a channel 

 similar to other boring insects." 



Only the males of the genus Solenobia are winged, and 

 the females have attracted much attention recently, in conse- 

 quence of the fact that they lay unimpregnated fertile eggs.
