LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 573 



32. P. demantrialis Druce. Antennae rather thick and rough-scaled at base. 

 Front strongly oblique, but without a cone; palpi rather long; fore wing with 

 Rs more curved than iisual, the wings narrow and subfalcate. Upper outer spur 

 of hind tibia of male only one-fifth the length of the inner. 



Fore wing shining lead gray, immaculate, the basal half overlaid with black- 

 tipped whitish scales. Hind wing somewhat paler toward base, not powdered. 

 20 mm. (Blepharomasti'X Druce; B(otarcha Hampson; chalybcalis Fernald 

 manuscript. ) 



July and August. 



New York, to Arizona, south to Central America. Xew York: Ithaca. 



P. singularis Lederer, from " North America," is probably a stray from the 

 tropics. It is described as flesh color with a black tuft at basal angle. 33 mm. 



P. venalalis Hulst and abdominalis Zeller are unknown to me; by the original 

 descriptions the first suggests Loxostege helvialis, and the second P. fissalis. 

 Torvalis and marginalis have been treated as Titanios. 



48. LOXOSTEGOPSIS Dyar 



Wings as in Pyrausta ; Sc and R of hind wing rarely approximate, instead of 

 anastomosing ( fig. 325 ) . Palpus beak-like, extending barely its length beyond 

 the head; maxillary palpi large and triangular, filling the space above the labials. 

 Tongue weak, typically obsolete. 



This may be the primitive genus of Pyraustinae, but in our present uncertainty 

 as to Pyralid evolution, I shall not disturb the customary order to put it at the 

 head. 



1. L. merrickalis Barnes and McDunnough. Brown -black; ante- and postmedial 

 lines darker, obscure on the dark ground, the postmedial sinuous. Head and top 

 of palpi clay yellow, contrasting. 15 mm. (Pyrausta Barnes and McDunnough). 



July. 



New Brighton, Pennsylvania. Xew York : Ithaca. 



49. THELCTERIA Lederer 

 (Eustixia Hiibner?) 



Palpi rather long and porrect obliquely, the third segment not long but well 

 marked and porrect; much shorter than in Scoparia. Maxillary palpi very large 

 and broadly triangular, as in Scoparia; front with a conical prominence; wings 

 broad with normal venation; all veins spaced. 



This genus is possibly an aberrant Scopariine. 



1. E. pupula Hiibner. White with about ten jet-black dots, some of them, 

 rarely, partly fused into ante- and postmedial lines; one spot basal, two terminal, 

 and one representing the reniform. Hind wing white, or with slight fragments of 

 postmedial and subterminal lines. 15 mm. (H 47:58.) 



Locally common all season. 



Massachusetts to Texas. New York: Poughkeepsie, New Windsor; Brooklyn, 

 and East New York, Long Island. 



Octonalis appears wholly unrelated, and is removed tentatively to Lygropia. 



Lineodes Integra Zeller, easily recognized by its entirely Pterophorid appear- 

 ance of wings, body, and legs, is a western species ranging east to Missouri. The 

 larva is pale green with a pale brown head and black spots on either side of 

 the prothorax. It webs the leaves of Solatium nigrum and other Solanaoeae.
