AMERICAN LEPIDOPTERA. 223 



C. umbra. Hufn., exprimens, Wlk. C. B. M.; Noet. 687 {Heliothis) ; angu- 

 lata, Grt., Trans. Am. Ent. Soc, Sept., 1874 (PI. VIII, figs. 14 and 15). 



The species is of a bright red brown color, with darker brown lines 

 arranged as shown in the figures fig. 1-1, showing the umbra form and 

 fig. 15 the extreme angulated form ; between the two there are any 

 number of inter-grades, and there is no doubt whatever in my mind of 

 the specific identity of the species. I have carefully compared both 

 forms with European specimens of umbra and have no doubt of their 

 specific identity, though there is a slight difference in the course of the 

 lines between the two. 



The larva of the angu/ata form has been described by Mr. Cocpuillet 

 in Papilio 1, p. 8, as follows: "Body bluish white; a yellowish brown 

 stigmatal stripe; from the stigmatal stripe on one side of the body to 

 that on the other side are about 1 black lines ; sometimes a dorsal row 

 of about 7 yellowish brown spots ; piliferous spots black ; venter pale 

 greenish ; head shining yellow, with a black spot on each side near the 

 jaws, the jaws sometimes black; length 1} inches. Several specimens 

 found upon smartweed [Polygonum Penn&ylvimimrn) September 15- 

 they entered the earth about three inches and formed oval cells Septem- 

 ber 27, disclosing the imagoes May 22, and a few days afterwards." 



Expands 1 j inches, 36— 12 millim. 



Habitat. — America and Europe. 



ALARIi, Westw. 



Eyes naked, globose, or very slightly narrowed ; front full ; head mod- 

 erate ; palpi exceeding front ; tongue strong ; body stout, strong ; vesti- 

 ture hairy ; abdomen of the usual Heliothid form ; wings moderate ; 

 primaries with obtuse apex and rounded outer margin ; tibia? spinose ; 

 anterior somewhat abbreviated, armed at tip with long inner claw-like 

 spines, and a series of shorter stout spines at outer side. 



Differs from Heliothis in nothing but the armature of the anterior 

 tibia — a very unsatisfactory distinction. I retain it as distinct because 

 I have given this character a generic value throughout the group, and 

 because the very marked superficial appearance will readily separate it 

 from Heliothis. The three species I place here were referred by Mr. 

 Grote to three distinct genera: Jlorida went to Phodo/ihora, gaurae re- 

 mained A/aria, while for ritriuellus an especial genus was created which 

 was termed Oxi/los. Mr. Grrote seems never to have suspected the 

 close relationship existing between these species and Heliothis, and he 

 places a number of entirely different forms between the two. In Can. 

 Ent. vol. 14, p. 172, he refers Oxy/os citrine// us to Heliothis, but seems not
