male; secondaries with more fuscous along costal and outer margins and on 

 the veins. Beneath : correspondingly darker. 



Expanse: 31-34 mm. 



Mr. Schaus informs the authors that there is nothing like the 

 present species in the National Museum from Mexico, and that it is 

 unknown to him. 



Type locality: Baboquivari Mts., Pima Co., Ariz. (O. C. Poling). 



Number and sexes of types: Holotype $, 1-15 Aug.; Allotype 9, 1-15 

 Oct.; 2 $ Paratypes, 1-15 and 15-30 July; all 1923. 



Leucochl^na Hamp. 



Type L. Jiispida Geyer. 



1906, Hamp., Cat. Lep. Phal. B. M., VI, 132, type designated hispida. 



Leucochl^na hipparis Druce. 



1887, Druce, Biol. Centr.-Am. Het., I, 272, pi. XXVI, f. 19, Heliophobus. 

 1906, Hamp., Cat. Lep. Phal. B. M., VI, 135, Leucochlcena. 



A single specimen { $ ) ix\ the Barnes Collection from Douglas, 

 Ariz., 15-23 May, agrees with Druce's figure, and with the series of 

 hipparis in the National IMuseum. There seems no doubt regarding 

 the authenticity of the locality label, so the species may be recorded 

 on Boreal American lists. 



Lepipolys Gn, 



Type L. perscripta Gn. 



1852, Gn., Spec. Gen., VI, Noct., II, 173, perscripta sole species and there- 

 type. 

 1906, Hampson, Cat. Lep. Phal. B. M., VI, 143, type designated perscripta. 



Hampson is erroneous in the statement that the frons of Lepipolys 

 is smooth. The type species, L. perscripta, apparently has a frons 

 varying from roughened to a definite conical corneous prominence. 



Guenee, in the original description, calls attention to the promin- 

 ence, "J'appelle I'attention sur le front, qui represente un entonnoir 

 tres-evase, ou plutot un couvercle conique, . . . ". 



L. behrensi appears to possess merely a roughened frons ; so that 

 in the genus Lepipolys there is a gradual transition from those speci- 

 mens of perscripta possessing a distinct frontal prominence thru speci- 

 mens of the same species in which this prominence becomes reduced
