A cnorahs is more restricte<l in habitat than any other species known to me! 
and the j^reater number of specimens seen are labeled "White Alts X II " 
( ther locahtjes-none of them very far from the White Mountains- are 
A^os.lanke, X. H., and Kangely, Ale. , lUanchard ) , and Camels Hump, Ah

The differential characters between this and the preceding species have 
a ready been set forth, and there can scarcely be any excuse for confusing it with 
any other. Some examples of scniiopacus show a complete lateral vitta which 
IS, however, of a paler, duller yellow and rjuite opa,,ue. not to mention the dif- 
ferently striate front and numerous dorsal ,)uucture.s by which the latter may 
always be readily separated. ^ 
This species occurs rather commonly in the Coa.st helt fi-om southern Men- 
doerno County, in California, through ( )i-egon, Washingtoii, \-ancouver ami 
l.ntish Columbia to Sitka arid Kenai in Alaska. It occurs at both low and hi<>h 
altitudes,^ at least toward the southeni portion of its i-ange, having heeii taken 
i''- =i''”vc 5000 ft., equivalent to 
an altitude of 8000 or (jooo feet in the southeni Sien-as." 
q. A’, obscunis Fall. 
As indicated in the synoptic table, the pre.seiit species and uitens may be 
.Irstinguished from our other species hy the fi-ont having seven striae between 
the broad lateral grooves. In my original description of obscunis the front 
was described as 8-10 striate, the lateral grooves in this ca.se being counted 
In addition to the number of the frontal striae, these two species occui.v an 
intermediate position between the 5-slriate and 12-slriate groups in .sewral 
other particulars. In sylraticus a tendency becomes manifest toward a re- 
duction of the punctuation of the under surface of the prothorax In obccunn 
this IS much more marked, the cpislerna becoming in most specimens very 
sparsely punctate or almost smooth, a condition which is the rule in nitens ami 
scmwpacus. In obscunis the sides of the prothorax are rather sharply rounded
