No. 1742. VEWLEPIDOPTERA FROM MEXICO DYAR. 257 



This form so closely resembles Heterocampa cubana Grote that I am 

 unable to make a differential description and refer to Grote's com- 

 parisons and figure. It is possibly the same species. Other Cuban 

 species are known from Mexico: but I prefer to keep it distinct for 

 the present. A single male specimen from Orizaba, which was in the 

 collection as the male of Heterocampa gelduba Schaus, undoubtedly 

 belongs here. It is not in perfect condition, but appears to have the 

 slenc.er angled line that runs up beyond the discal mark less dark and 

 sharply defined than in cubana. The same difference appears in 

 the females also. Also very closely allied to these species is Hetero- 

 campa aroensis Schaus from Venezuela and British Guiana, which 

 resembles more cubana in the character of the line mentioned. I 

 presume that these three forms are really only local races of one 

 species. 



HETEROCAMPA GELDUBA Schaus. 



This species was described from Mexico, and seems to be not un- 

 common. I have above taken away the only male specimen, but 

 am able to supply another, which I believe is the true male. The 

 specimen comes from Mr. Muller, and was taken in Orizaba in June, 

 1908. It is easily, distinguished from the foregoing by the wing- 

 shape. Both sexes have shorter, squarer wings than in androdora, 

 cubana, or aroensis. 



Genus NAGIDUSA Walker. 

 NAGIDUSA SUAVIS, new species. 



Body dark gray. Fore wing bluish gray with slight violaceous 

 tint, the costa shaded with ocherous and brown; base shaded with 

 dark gray and brown, a narrow black line at base on submedian fold; 

 inner line showing traces in brown; discal mark a brown curved line 

 surrounded by ocherous shading; outer line indicated by brown 

 dots on the veins, doubled, filled with ocherous, inclosed in an ocher- 

 ous and brown shading on the costa; veins with short black dashes 

 in the subterminal space, followed by dots. Hind wing whitish, 

 the fringe gray brown: veins 6 and 7 marked in brown and crossed 

 by a faint white shade outwardly. Expanse, 40 mm.
