This is the common Arizona species and is represented in the 

 Smith Collection by a series of specimens. L. venatus is larger and 

 with more of the pinkish-red on the primaries. It is represented in the 

 Smith Collection by the unique type ( 2 ) from Santa Fe, N ,Mex, 

 The frontal structure is the same in the types of both names. It is 

 possible that venatus may be a very large red variety or race of 

 radiatus, but the authors are not yet willing to propose this synonymy. 



Hampson's figure (1910) is correct. Barnes and McDunnough's 

 figure of "venatus" (1912, Contr. N. H. Lep. N. A., I, (4), 49, pi. 

 XXIII, f, 8, Lythrodes.) is radiatus.

Several specimens have been received from Baboquivari Mts., 

 Pima Co., Arizona, (O. C. Poling), dates 15-30 August and 1-15 Sep- 

 tember, which agreed well with Druce's and Hampson's figures. Speci- 

 mens were sent to the National Museum for comparison, and agreed 

 with a single specimen in that Collection, except in size, being slightly 

 smaller, 28 vs. 29 mm. Hampson lists the unique female type as meas- 

 uring 34 mm. There is little doubt but that the Arizona and Mexican 

 specimens are conspecific. altho it is possible that further material from 

 both the United States and Mexico may show that the Arizona speci- 

 mens are v/orthy of a racial name founded on size alone. 



Hampson's diagnosis of Chrysoecia is apparently in error in that 

 the frons has a raised ring, with a small central tubercle connected 

 to the vertex edge of the raised ring by a slight vertical ridge, while 

 below this tubercle there is a horizontal raised ridge ; followed by the 

 corneous clypeal plate. The fore tibia is armed with a distinct claw 

 nearer the inner than the outer side and which is more or less hidden 

 by the tibial vestiture. Such characters would cause the genus to 

 fall in Hampson's keys somewhere between Chalcopasta and Stiria; 

 but abundantly distinct. It is closely related to Polenta (type tepperi).
