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 not 

 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 who 

 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 e 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. 



NEPTICULA. 



N. fuscotibiella. Antennas dark fuscous, basal joint silvery- 

 white. Head reddish-yellow. Fore-wings purplish-fuscous, 

 with a rather broad, slightly oblique silvery band exterior to 

 the middle of the wing. On the costa of the wing the band
