at the termination of the siibmedian veins being apparently constant. 

 Reverse: the under side is the same, except that between the costal spots 

 the color is white instead of orange. Abdomen vermilion above, with a 

 narrow dorsal median band of black, of uniform width ; below white; 

 laterally a narrow band consisting of gray spots margined with black. 



Female. — Head, thorax and prinraries same as male, the replacing of 

 the orange with vermilion on the under side of primaries, except along^ 

 the costa, being more marked than in the male. The secondaries are 

 vermilion, bordered at the outer margin by narrow band of gray, which 

 is broken, so that a spot shows at the termination of the second subme- 

 dian vein. The wing is crossed by three irregular gray bands, of which 

 the outer is the widest, the three becoming confluent near the anal angle. 

 These bands are bordered with black; the basal area is vermilion. On 

 the under side the secondaries show similar markings, the vermilion giv- 

 ing place to white in places, and to orange along the cor.ta, more espe- 

 cially near the base; otherwise the basal area is vermilion. The abdomen 

 is vermilion above and white below. On the dorsal aspect of each seg- 

 ment is a gray spot, margined with black, together forming a median band 

 in width equaling one-third of that of the abdomen; laterally a row of 

 minute gray spots. On the last segment the dorsal and ventral surfaces 

 are divided by an orange spot. On the ventral surface two sublateral 

 and one median row of three gray spots, the former small, and the latter 

 united into a triangular spot of considerable size. Expanse: (^ 45 mm.; 

 $ from 55-60 mm. 



Types: male from Mexico, and female from Colorado, in col- 

 lection of the author. Male coll. Mr. Doll, and female in coll. 

 Mr. Dyar, both from Colorado. With the exception of the Las 

 Vegas specimen these insects were captured by Mr. Bruce. 



In the plate which accompanies this article the upper figures 



are male and female of aulea, the second pair are typical pida, 



the third maia and the last citra. 



The following is a comparison of the species showing the chief 



marks of distinction: 



COLORATION. 



Aulea. — Primaries, upper side, dark slate and creamy-white. Seconda- 

 ries crimson and blackish ; under side crimson and blackish, with 

 white along the costa of secondaries in females. 



Picta. — Primaries, upper side, pale slate and creamy-white. Secondaries 

 pale slate and carmine; under side pale slate and orange, the latter 

 replaced with carmine on lower half of secondaries. 



Maia. — Primaries gray and white, latter outlined heavily with black. 

 Secondaries vermilion and gray, hyaline in males; under side gray, 

 vermilion, white and orange, the colors predominating in the order 

 named.
