SATURNIIDAE 



Hemileuca electra CLIO var. nov. (PI. XIII, F'igs. 1, 2). 



As compared with typical electra from the San Diego region this 

 Arizona race differs as follows : the thorax and patagia are black, 

 the latter bordered with pale yellowish (in electra this whole area is 

 covered with mixed black and pale yellow hairs) ; with the exception 

 of the pale median band enclosing the reniform the whole of the 

 primaries are black (in electra there are two whitish basal streaks 

 and considerable pale subterminal markings) ; the median pale band 

 is much as in typical electra but the central pale lunule in the round 

 black spot is rather narrower than usual. The secondaries are a rich 

 deep brick-red much more heavily scaled and deeper in color than in 

 electra, the 9 before us showing considerable blackish suffusion 

 beyond the discal mark; in our $ specimen this mark is merely a 

 round black patch without pale central dash, in the 9 a narrow pale 

 central streak is present. Beneath the color is much deeper than in 

 the typical form and the pale abdominal rings are narrower. Expanse 

 $ 52 mm. ; 9 63 mm. 



Habitat: Kingman, Ariz. (Oct.) 1 $, I 9. Types, Coll.
