Sphingidae 



Georgia and westward to the eastern boundaries of tiie great 

 plains. 



(4) Haemorrhagia senta Strecker, Plate IV, Fig. 5, $ . 

 (The Californian Clearwing.) 



Svn. ruhens Hanham (non Edwards). 



The head, thorax, and basal segments of the abdomen are 

 brownish-olivaceous. The abdomen is black. The two seg- 

 ments immediately preceding the terminal segment are marked 

 laterally by yellow tufts of hair. The anal tuft is wholly black. 

 The wings are very narrowly bordered with brown. There is 

 no rusty red spot at the apex of the primaries. The clear 

 portions of the wing in certain lights have a bright steel-blue 

 luster. The under side of the palpi, the pectus, and the 

 abdomen are pale straw-yellow. In size this species is about 

 as large as H. d/ finis. 



The perfect insect occurs in Utah and California, frequenting 

 the blossoms of Litpinus. 



(5) Haemorrhagia thetis Boisduval, Plate 11, Fig. i, S. 

 (The Thetis Clearwing.) 



Syn. pal pedis Grote; riibcns Edwards. 



Decidedly smaller than either of the two preceding species. 

 The thorax is olive-green, passing on either side into pale 

 yellov/. This color is continued dorsally on the abdomen as far 

 as the terminal segment, but is more or less lost in the broad 

 yellow preanal band. The basal and middle segments of the 

 abdomen are marked laterally with black, and the anal tuft is 

 correspondingly marked with black on either side. The 

 marginal band of the fore wings is narrow, as in H. diffinis, and 

 is always distinctly marked above and below at the apex by a 

 rust-red triangular spot. The wings at their insertion are more 

 or less shaded with pale rusty red both above and below. 



This species ranges from Colorado and Wyoming westward 

 and northward to Oregon and British Columbia. It has been by 

 Dr. Dyar made synonymous with the following species, from 

 which it is, however, quite distinct. 



(6) Hsemorrhagia brucei French, Plate 11, Fig. 7, $ . 

 (Bruce's Clearwing.) 



This is a small species, in size approximating H. thetis, from 

 which it may be at once distinguis;hed by the green color of the
