LOTISMA, new genus. 



Type Sciaphila trigonana Walsingham (Dyar's List N. 

 Am. Lep., No. 5413). 



Tongue very long, spiraled. Labial palpi long, rather straight, up- 

 turned, reaching vertex ; second joint very long, roughly thickened with 

 loose scales towards apex; third joint short, thick, smooth with apex 

 obtuse. Face and head with smoothly appressed scales. Fore wings 

 about three times as long as broad; costa nearly straight, but slightly 

 deflexed at the pointed apex ; termen straight and oblique ; dorsum 

 straight ; 12 veins, all separate ; internal vein from between 10 and 11 to 

 between 8 and 9 ; 7 to below apex ; 3, 4, and 5 from the end of the cell ; 

 2 from apical fifth of the cell; \b furcate at base; \c distinct. Hind 

 wings wider than the fore wings, with straight costa and rounded 

 tornus ; 8 veins ; 3 and 4 short-stalked ; 6 and 7 parallel ; 5 radial, near- 

 est 6. Posterior tibiae smooth. 



The genus much resembles Hcmerophila, but has more thick- 

 ened palpi and differs in the position of the internal vein in the 

 fore wing and of vein 5 in the hind wing. 



The type species, described as a tortricid by Lord Walsing- 

 ham, was redescribed by the writer as Hcmerophila kincaideUa 

 (Proc. U. S. Nat. Mus., xxvn, p. 746, 1904). 



Olethreutes albiciliana Fernald. 



Miss Cora H. Clarke, of Boston, who for many years has 

 made interesting contributions to life histories of insects and 

 to whom the writer is under obligation for several valuable 

 biological notes, notably the life history of the new genus 

 and species Ectocdemia populella* sent me last fall stalks 

 of the common "touch-me-not" (Imp aliens) containing larvae 

 of a tortricid, which this spring proved to be the above 

 pretty species. 



Miss Clark observed the larva during summer, and in Sep- 

 tember collected them in abundance at Magnolia, Mass. 



The larva lives in the hollow stalk and in the succulent pith 

 in the swelled joints ; it overwinters as larva and towards 

 spring gnaws a small circular hole in the stalk near a joint, 

 leaving only the extreme epidermis intact as a semitransparent 

 port hole; just inside this it spins a few threads of silk and 

 pupates with its head toward the window, through which even- 

 tually the imago issues. In the insectary the first moth issued 

 the latter part of April. 



The writer has observed larvae with similar habits in^Impa-
