Length 10 to 20 mm. Under A. cribripennis , Doctor Le Conte com- 
ments that a specimen from Oregon has the elytra black and that two 
other specimens were black with red shoulders and finally says: 1 
“Finding no difference but that of colour, I not only believe these to be merely vari- 
eties, but also suppose that A. canadensis Fabr. and A. erythroptera Kirby (nec. Germ.) 
are corresponding varieties of another species, the entirely black variety of our eastern 
species is as yet unknown.” 
Doctor Hamilton* considered the European A. variicornis Dalm, to be 
the same as erythroptera or cinnamoptera. In his “Distribution of the 
Coleop tera,” he says of A. canadensis , “very variable,” 
“ Variicornis Dalm. should be compared with erythroptera or cinnamoptera, as a com- 
parison with typical canadensis would be misleading,” “Across the northern part of the 
continent from the Atlantic to the Pacific through the Rocky mountains, to New Mexico 
and also in the Alleghanies. Europe (northern Germany, Russia), western and common 
in eastern Siberia to the north of the Amur.” 
“An entirely black example was taken in Japan by Mr. George Lewis.” 
Later, Leconte 3 himself evidently considered his own cribripennis as 
canadensis, for he enumerates it in his synonymy in his key to Leptura. 
In the material that we have examined there are two types of puncta- 
tion and lustre that deserve consideration. In the western form known as 
cribripennis, which extends eastward to Manitoba, the punctation of the 
elytra is constantly very coarsely cribrate throughout and the interspaces 
between the punctures are polished, giving the elytra a bright, shining 
lustre. In the females of the eastern form, the elytral punctation is con- 
sistently smaller, particularly on the caudal half, and the interspaces 
between the punctures are finely reticulate, giving the elytra a decidedly 
opaque lustre. The males of the eastern form are in many cases inter- 
mediate in both punctation and lustre between these two conditions. In 
colour, the western material shows a greater variation; many individuals 
have the elytra entirely black (females in all we have seen), or black with 
minute red basal spots; some have the elytra entirely red, or red with the 
apices black; and the majority have the elytra black with a red basal band 
of variable width, in many cases covering the basal third and occasionally 
the basal half. The caudal margin of the red band is usually strongly 
arcuate. In the eastern form the elytra are usually black with a narrow, 
basal red band rarely covering more than the basal fifth, and specimens 
with the elytra entirely red, or red with the extreme tips black, are not 
uncommon. The entirely black variation has not been seen by us from 
the eastern part of the continent.
