of both are the two least allied species in the genus. This is unfortunate but 

 cannot be helped, any series at all will immediately put these extremes in their 

 proper places. 



Specimens from the vicinity of Durango, Colo, show a tendency to 

 "throw" intermediates to the type form in the banding of the underside ; speci- 

 mens from Turkey Creek Cannon, Colo. (Oslar) show the upper side dark and 

 the under side as in typical specimens of the Colorado race thus producing an 

 insect which often very closely matches the southern California race of C. 

 dumetorum; but material from the vicinities of Denver and Bouldet seem to 

 produce few if any, intermediates to typical C. apama. 



Type localities and number and sexes of types: Holotype $, Golden,

 ing canons, May to August. 



SPHINGIDAE 



Arctonotus lucidus race clarki nov. 



Similar to A. lucidus, but the maculation is more intensified, and the 

 ground color of the primaries and secondaries much deeper in tint; thus creat- 

 ing a considerable difference in appearance. Beneath : much deeper fuscous than 

 typical A. lucidus; the central area of the primaries and secondaries tinged with 

 red, the red on the secondaries obsolescent in some specimens. 



Specimens appear considerably larger than A. lucidus lucidus, due to being 

 heavier bodied and broader winged, the breadth of the primaries being ap- 

 proximately one millimeter more than the tj'pical form. 



Expanse: About 51 mm. 



This is apparently what Rothschild and Jordan consider typical 

 A. lucidus, but Boisduval's type came from San Francisco and sixteen 

 specimens before the authors, ranging in distribution from Humbolt 

 Co. to San Diego Co. represent only a single race. 



The authors v/ish to acknowledge v/ith thanks the loan of seven 

 specimens of typical A. lucidus by Dr. E. P. VanDuzee. 



Type locality: Pullman, Washington. 



Number and sexes of types: Holotype $ , 21 March 1901 ; 2 $ Para- 

 types, 14 and 21 March 1901.
