Sphingidae 
Georgia and westward to the eastern boundaries of the great 
plains. 
(4) Haemorrhagia senta Strecker, Plate IV, Fig. 5, $. 
(The Californian Clearwing.) 
Syn. rubens 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. diffinis. 
The perfect insect occurs in Utah and California, frequenting 
the blossoms of Lupinus. 
(5) Haemorrhagia thetis Boisduval, Plate II, Fig. 1, $. 
(The Thetis Clearwing.) 
Syn. palpalis Grote; rubens Edwards. 
Decidedly smaller than either of the two preceding species. 
The thorax is olive-green, passing on either side into pale 
yellow. 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) Haemorrhagia brucei French, Plate II, Fig. 7, 
(Bruce’s Clearwing.) 
This is a small species, in size approximating H. thetis , from 
which it may be at once distinguished by the green color of the
