to have suspected the possible identity of A/aria with it, although struc- 

 turally it even more closely resembles it. 

 The species are readily separable as follows : 



Anterior tibia with a single long inner spine. 



Primaries bright red, with yellow outer margin florida. 



Primaries whitish, with base, a longitudinal median shade, margin and an ob- 

 lique shade from apex toward internal margin red gaurae. 



Anterior tibia with two long inner claws. 



Primaries pale yellow <i I roue] his. 



A. florida, Guen., Noct. 2, 171. pi. 2, fig. 7 (Rhodophora). (PI. VII, fig. 7, 

 tibia, PI. VIII. fig. Ifi. wing.). 



Strongly marked and readily recognized by the beautiful red primaries 

 shaded outwardly with pale yellow. The larva of this species is described 

 by me in Bui. Bkln. Ent. Soc. vol. 4, page 28. It feeds on the buds 

 and seed capsules of the evening primrose, and is of the same delicate 

 green color as they are ; of a velvety appearance and clothed with short 

 dense pubescence ; its habit is to lie horizontally along the bud or seed 

 capsule, and boring a hole near the tip to feed downward into it, gradu- 

 ally disappearing from view ; this habit, unknown to the collectors in 

 general, explains why the larva is not often found, though its food-plant 

 is well known. It becomes full grown in August and September, trans- 

 forms to a pupa about six inches below the ground, and the imago 

 emerges the following July, when it is often found early in the morning 

 in the closed flowers of the evening primrose. 



Expands \\ inches, 30-36 millim. 



Common in New York, and I have received it from Utah. 



A. gaurae, Sm., Abb. Ins. Ga. 2, p. 197, pi. 99 (Phalaena), Porph/rinia 

 matutina, Hb. (PI. VII. fig. 8, tibia, and PI. VIII, fig. 17, primary). 



Nearly allied to the preceding in the bright colors, but readily separ- 

 able by the form of marking, as shown in the figure, as well as by the 

 armature of the anterior tibia. It seems to vary somewhat in the ex- 

 tent of the red markings and in the clearness of the white ground 

 color. Expands as before. 



Habitat. — Florida and Southern States. 



A. eitrouellus, G. & R., Trans. Am. Ent. Soc. 3, ISO, pi. 2, fig. 79 (Helio- 

 this): Orylos, Grt.. Check List, 1S75, note 25. Heliothis, Can. Ent. 14. 172 (PI. VII, 

 fig. 9. tibia). 



Differs from the preceding by the armature of the tibia, as well as by 

 the uniform pale yellow of primaries. The figure of the tibia shows a 

 side view and is somewhat distorted. Expands 1 \ inches, 30 millim. 

 Habitat. — Texas and Colorado.
