one locality and the junior author while in Mississippi reared both 

 from one lot of larvae. The other reason is that we fear corollaria, 

 Perry or I'aria, Wlk. may fit one or the other of the forms. The 

 original description of varia, Wlk. rather sounds like the yellow form 

 of lilith. Only accurate comparison with the types will ever enable 

 anyone to give a logical synonomy for the various Eastern or South- 

 ern races and forms of io and lilith. Type locality, Atlanta, Ga. 

 Types, 4 $ s, Field Museum (Collection Strecker). 



In conclusion we venture to describe two new races, one from 

 New Mexico and the other from Texas. 



AuTOMERis 10 race neomexicana, nov. 



The females show the differences from the described forms and races of 

 A. io in excess of those shown by the males; as is typical of all the races. 

 Female : head and thorax similar to coloradensis, abdomen luteo-fuscous, each 

 segment banded with deep rose cephalically. Primaries : t. a. and t. p. lines 

 narrowly marked with blackish, which is bordered on the outside of the t. a. 

 and inside of the t. p. with a conspicuous whitish line. Reniform but faintly 

 distinguishable, outlined with a few whitish scales, centrally darker, almost mak- 

 ing contact with the t. p. line. S. t. line pale, inconspicuous, but bordered inter- 

 nally by conspicuous triangular or subtriangular spots between the veins, these 

 spots being of a deep grayish-purple color. Ground color of primaries deep 

 fuscous brown heavily powdered with grayish-purple scales; medial and ter- 

 minal areas darkest; due to more of the powdering; s. t. area somewhat paler, 

 except for the triangular spots mentioned previously, basal and subbasal areas 

 heavily clothed with long rufous hair. Secondaries as in coloradensis but with 

 the purplish suffusion less pronounced, more nearly as in "tjT)ical" io. 



Male : one specimen shows the ground color and maculation very similar 

 to that of fuscus, another has somewhat the general cast of the yellow form 

 of lilith while a third shows the distinct rufous cast quite strongly pronounced. 

 The reniform is more conspicuously outlined in blackish than any specimens 

 before us except some of the males of lilith. 



We place this form between fuscus and lilith. 



It is easily distinguishable in the female by the amount of dark powder- 

 ing on the primaries combined with the dark patches between the veins ; and 

 in the male by the general resemblance to the yellow forms of lilith in macula- 

 tion and often in color, and by the pronounced black ringed reniform. 



Type locality and number and sexes of types: $ Holotype; $ Allotype; 

 2 5,1 2 Paratypes; all from Jemez Springs, New Mex., and all June 8th-15th 

 except one $ Paratype which is without date.
