inflated in front, the disk rather coarsely, sparsely punctate with the 
interspaces distinct; the elytra rather coarsely, moderately closely punc- 
tate, not granulate; elytra and pronotum much more coarsely punctate 
than in subargentata; the legs bright yellowish red. 
The type series, two males, were studied. 
Type locality: “Gala.” 
(7) Grammoptera ruficeps Lee., 1862, Proc. Acad. Phila., p. 40. 
Length 4 to 6 mm. The legs of this species are generally bicoloured, 
the mouth parts and scape of antenn® red, with pronotum black. The 
tibial spurs are short. Grammoptera ruficeps seems to be closely related to 
Grammoptera ruficornis of Europe. 
Ten specimens are before us from Massachusetts, New Brunswick, 
Ontario, and Manitoba. 
The type locality is given as “Upper Georgia,” in the Leconte collec- 
tion. 
(8) Grammoptera filicornis Csy., 1913, Mem. on the Coleop., p. 255. 
Length 6 to 8*5 mm. In the numerous specimens before us from 
Colorado and British Columbia, the colour is consistently black, including 
the legs. The elytral vestiture is longer and more conspicuous than in any 
allied species. In Colorado it commonly occurs on a species of wild ge- 
ranium and in British Columbia it is very numerous on the wild rose. 
One hundred and ten specimens have been examined in this study from 
Colorado, New Mexico, and British Columbia. 
Type locality: Washington. 
ALOSTERNA Mulsant 
1863, Col. Fr. (ed, 2), p. 576. 
The pronotum is elongate, inflated in front of the middle, the hind 
angles only feebly produced; the pubescent sole well developed on the 
first three segments of the posterior tarsi; the cheeks somewhat shorter 
than the width of the mandibles at the base; the antennae with distinct 
poriferous impressions, in the form of grooves or distinct pits on the distal 
segments from the 6th to the 11th; the prosternum convex, the forecoxal 
cavities narrowly open behind; and the head is separated from the neck by 
an abrupt transverse impression across the dorsum behind the eyes. 
Genotype, ( Leptura ) tabacicolor DeG, 
The Californian species, rubida Lee., has heretofore occupied an in- 
definite position in the genus Anoplodera; but it is evidently congeneric 
with the European species, tabacicolor DeGeer of the genus Alosterna 
Mulsant, with which it agrees particularly in the impressed antennal seg- 
ments and the peculiar shape of the pronotum. 
Three exotic species are known, A. elegantula Kratz from China, A. 
scapulans Heyden from Persia, and A, tabacicolor DeGeer from Europe 
and Siberia. Specimens of tabacicolor are before us. The species chalybae 
Hald., capitata Newm,, and keeni Csy. are closely allied to rubida and are 
included here in Alosterna; chalybea may eventually be separated as a 
distinct genus.
