The prothorax varies a good deal in form and sculpture. In some 
specimens it is very narrow posteriorly, in others less so; the surface is 
generally very finely strigate with or without coarse punctures, the latter 
when present more numerous at apical region, a little less so near base 
and sparse on the disk; the strigation is often exceedingly fine and 
occasionally almost absent on the disk. The hind femora are generally 
unarmed below in both sexes, often more or less acutely angulate, but 
apparently rarely with a very small acute tooth and then principally in 
males. 
This is one of the two species considered to be femoralis Kirby, 
labelled in Dr. Horn's collection germari where the true germari is labelled 
femoralis. The above- described new species and germari are, however, 
two entirely distinct species. D. germari has a shorter and differently 
sculptured upper and lower surface of prothorax, rather robust but feebly 
clavate hind femora, armed below with a moderately large tooth, apex 
of last abdominal segment emarginate in both sexes, elytra wider and 
the lower and upper vaginal plates of the females are entirely different 
in the two. 
D. longicollis is distinguished by its rather narrow and elongate form, 
relatively long prothorax, its very fine sculpture and distinct lateral 
tubercles and generally unarmed or at most feebly toothed and distinctly 
clavate, bicolored hind femora. D. wallisi is also a narrow and rather 
elongate insect, especially the males, and the prothorax is frequently 
finely strigate-rugose, but is shorter with tubercles less prominent 
laterally, the side pieces of prosternum finely strigate-rugose, the lateral 
margin at most acute only for a short distance from base and then 
always more or less interrupted and the neck behind the head is narrower. 
Judging from the number of specimens seen in most of the older 
collections, including those of the British Museum and of the Entomo- 
logical Branch in Ottawa, this species has been commonly taken at 
Inverness and Metlakatla, Brit. Col., by the late Rev. J. H. Keen. It 
is apparently also common in California, at least in certain localities,
