NO. 1283. REVISION OF SOME NOCTUID MOTHS— SMITH. 207 



.secondaries range from dirty white to smoky. Beneath, rangino; from 

 ahnost immacidate whitish to dirty fuscous or yellowish; sometimes 

 with only the disk of primaries blackish. 



Ex])ant<e. — 1.08 to 1.15 inches (27 to 2!» mm.). 



Jlahlfat. — Denver, Colorado, July 1.5 (Bruce, Oslar); (TJeinvood 

 Springs, Colorado, July lO-Aug-ust 16. 



Six examples all very much alike above and no two alike beneath. 

 There is more ditfei-ence in the color of the secondaries than in the 

 primaries, and on the whole not enough anywhere to cause doul)t. 



Type.—^o. 6253, U.S.N.M. 



NELEUCANIA PATRICIA Grote. 



IMio}>lii/a p'ttricia Grote, Bull. Bkln. Ent. Soc, III, ISSO, p. 46. 

 Leucanin jxilricia Smith, Bull. 44, IT. 8. Nat. .AIus., 1893, p. ISH. 



"Fore wings ^-ellowish buff. A silvery-white stripe on the median 

 vein, extending on vein -t. Above this a dusky stripe, from the base 

 outwardly to near the margin. Veins and costal edge whitish. Thorax 

 buff'. Hind wings white. Beneath whitish." 



Expanse. — 1.05 to 1.12 inches (26 to 28 mm.), 



Hahitat.—i^oXovA^o (Bruce); Las Vegas, New Mexico; Hot Springs, 

 New Mexico, 7,000 feet (Hulst). 



Only three examples arc before me at present; but I have seen others 

 and noted no essential differences. The species is so unlike anj^ other 

 as to be recognizable at a glance. 



NELEUCANIA PR^GRACILIS Grote. 



Heliophila pnegracilis Grotk, Bull. Geol. Surv., Ill, 1877, p. 119. 

 Leucania priegracilis Smith, Bull. 44, U. S. Nat. Mus., 189:5, p. 185. 



" The most slender species of the genus. Eyes hairy. Smaller and 

 slighter than pa Hens. Yellow white, not buff' as in jta/fr/hs, absolutely 

 immaculate. Head and thorax more yellowish. Length of primary 

 12 mil. One specimen, Idaho, July 6. This .species seems slighter 

 than Senta defecta Grt." 



The above is Mr. Grote's description, and 1 can add nothing to it 

 from personal knowledge. Colorado and New Mexico are cited as 

 additional localities in my catalogue, but 1 can not now rememl)er on 

 what authority. 



Of the species catalogued by me in 189,3 and not elsewhere referred 

 to in this paper, Leucania riifostriga is a Caradrina and probaljly the 

 .species described by me as C. pyunctivena. Dr. Packard's type is in 

 the Museum of Comparative Zoology at Cambridge, and Mr. Henshaw 

 very kindly compared with it a Labrador example which Dr. Dyar 

 suggested might have been intended. The suggestion proved accurate 

 and I believe that the differences between this example and the British- 

 American specimens are not sutticient to hold my species.
