course with a very even or not great onteuive. This line is often obscure, 

 and the pale line is accepted as the true transverse posterior line: which 

 it is not. Subterminal line whitish, denticulate, a little marked by pre- 

 ceding black scales; sometimes interru]>ted. Three white costal dots 

 before the apex, which is whitish or gray. An interrupted black ter- 

 minal line, ])receded by a white line. Fringes usually long, brown at 

 base, with a bhick interline; smoky at tip. The ordinary spots are 

 composed of small i)atclies of elevated scales. Secondaries fuscous to 

 smoky or blackish, immaculate. Beneath gray to smoky, immaculate 

 except for a blackish terminal line and a white anteapical costal blotch 

 on primaries, which is fre(iuently absent.

A specimen from the United States National Museum is marked "No. 

 2584, on Vrcna lahiata; Iss. March L>0, 1882.'' 



This little species is not common in collections, though probably not 

 rare in nature. 



Its synonymy, unfortunately, is scarcely settled. In my studies in 

 the British Museum 1 found a specimen which I took as the type of 

 Hypena hhcnsali.s, Walker, and which I considered the same as H. citata, 

 Grote, and so referred it m my catalogue. Mr. Butler writes, later, 

 that this is a mistake, and that Walker's species is not even a Hypena. 

 The description somewhat bears out Mr. Butler's statement, and I have 

 apparently made some mistake, though how I can not conceive. I 

 can hardly believe that I would have failed to recognize this species, 

 however poor. On the other hand, Mr. Burler suggests that Mr. Grote's 

 species IS Guenee's Bypena exoJetalis, from Brazil (Gn. Delt., 20). The 

 description is fairly applicable except as to size, Guence giving 25 mm. for 

 the female, while no specimens I have ever seen exceeded 19 mm. Yet 

 Mr. Butler may prove to be right when sufticient material is at hand. 



The species is the smallest in our fauna, in ludicrous contrast to the 

 only other species with long, straight pali)i. The oblique line of elevated 

 scales and the false, pale, transverse posterior line are characteristic 

 features, and distinguish the species. Tin; male is a little more robust 

 than the female, but I have noted no other differences.

" This brown and light purple Texan species differs by the sagittate, 

 pale, subterminal line becoming white at ai)ices, and followed by dark 

 marks. A fine white line bordering inwardly the dark line on the 

 terminal margin. A dark diffuse shade from the disk crossing the sub- 

 terminal line and extending upwardly to apex. Transverse anterior 

 line dentate; transvese posterior line continuous and nearly even. 

 Beneath the apical pale dots are prominent. BelfrageNo. 213, expanse
