and the spot at base of wing there is an elongate spot in the type and para- 

 types not present in any specimens of blaisdelli or distanti so far examined, 

 nor mentioned in the description of those species. The W-mark at the fore 

 margin has but the outer lines present. Metanotum black, the hind margin 

 and sides yellowish. Dorsum of the abdomen black with the hind margins 

 of all of the segments edged with yellow. Beneath, the legs are yellow lined 

 with black on the tarsi, tibiae and femora, the fore tibiae being nearly all black. 

 Each abdominal segment is black centrally at base and yellowish on the pos- 

 terior margin and sides, each yellow side area includes a clouded spot. The 

 last ventral segment has the posterior half yellow and the valve is yellowish 

 clouded centrally with fuscous.

In addition to the type, three other males collected at the same 

 locality and at the same time have been examined. The smallest has 

 an expanse of wings of 44 millimeters but otherwise closely resembles 

 the type. The almost total obliteration of the stigma at the end pf 

 the cubital cell will serve to separate this species from the two others 

 in the genus. It also has narrower fore wings and more prominent 

 front than distanti, and the veins of both pairs of wings are not as 

 stout and black as in blaisdelli. As San Fernando in Lower Califor- 

 nia, Mexico, is only a little over two hundred miles south of San 

 Diego County, California, C. astigma will very likely be found within 

 the limits of the United States. 



The following additional records of specimens of CUdophleps in 

 the author's collection or examined by him may be of interest.
