ilar but larger and has the legs colored asin puritana. Ihave 
assumed that the head in brunnipes is distinctly wider than 
the prothorax but appear to have made no note on this point ; 
the original description of LeConte is wholly inadequate. 
The species described in the table under the name angusticeps 
is founded upon a specimen which I formerly regarded as the 
male of rotundiceps (Bull. Cal. Acad. Sci., 6, p. 218) but 
more careful comparisons indicate the impropriety of this 
association. ‘There are before me two forms allied closely to 
brunnipes, which are left undescribed for the present; they 
occur at Lake Superior and in Montana (Kalispell). 
Scopaeopsis n. gen. 
This genus is one of the most isolated of the Scopaei, not only 
in general habitus and comparatively large size of its species, 
but by reason of labral structure, long slender tarsi —a char- 
acter shared only with Scopaeodera— and elaborate secondary 
sexual modifications of the male. The integuments are clothed 
rather sparsely with very fine short and decumbent hairs and 
the punctures are, except on the elytra of certain species, 
excessively minute or subobsolete, being practically filled by 
the bases of the minute hairs. The species are moderately 
numerous, inhabiting the entire eastern parts of our territory, 
not known to me to extend west of the 100th meridian and 
entirely unknown to the Sonoran and Pacific coast faunas. 
The five species in my cabinet may be indicated as follows :—
