We are unable to separate these colour forms by any definite charac- 
ters. The elytra are unusually stout, cuneiform, and the apices are very 
strongly dehiscent. 
A. cuneatula Csy. agrees in all respects with individuals in our series 
of vagans Lee. A. fusella Csy. in the Casey collection is a single male with 
fuscous elytra, and the head and pronotum more sparsely punctured than 
usual, but not more so than in some of our series. The type of A. puella 
Csy. has red humeri. The second specimen is very coarsely punctured and 
shining, added after the original description was written. The second speci- 
men mentioned in the text is in the Casey collection as teirica Csy., a male, 
entirely piceous with the pronotum slightly wider than usual. A . cham- 
plaini Csy., type, is a large female of vagans with red elytra; the second 
specimen is similar but darker in colour. These forms seem to us all 
individual variations; there are many such variations in our long series, 
including size and density of punctation, precise shape of pronotum and 
elytra, and width between the eyes. 
Forty-three specimens have been examined from Nova Scotia, New 
Brunswick, Ontario, Wisconsin, Pennsylvania, and Alabama. Other local- 
ities cited in literature: New Hampshire, Massachusetts, New Jersey, New 
York, Virginia, North Carolina, Georgia, Michigan, Maine. 
Host plant: Pinus (Craighead).

subquadrata Csy., 1913, Mem. on the Coleop., vol. IV, 
p. 251. 
Length 7 to 8 mm. The antennae of this species are annulated, the 
elytra testaceous, with humeri and apices black, the apices feebly dehiscent 
and transversely truncate. 
A. subquadrata Csy. is represented in the Casey collection by a single 
female, at least very closely allied to circumdata Oliv. It is stouter than 
usual with the head exceptionally wide between the eyes and the hind 
angles of the pronotum distinctly flaring. It may prove to be a distinct 
species. 
Nineteen specimens have been examined from New Jersey, Massa- 
chusetts, and Pennsylvania. 
(53) Anoplodera pernigra Linell., 1896, Proc. U.S. Nat. Mus., vol. 19, p. 397. 
Length 9*5 to 11 mm. The colour is entirely black. The hind tibial 
spurs are unusually short. It is in many cases found on umbelliferous 
flowers at an elevation of about 6,000 feet in Sierra Nevada mountains, 
California. 
Twenty-five specimens have been studied from Kern and Tulare 
counties, California, in addition to the type series in the collection of the 
U.S. National Museum. 
Type locality: Wilsons Peak, Los Angeles county, California.

Length 9 to 10 mm. Dr, Van Dyke spoke of the variation in this 
species before the Philadelphia Entomological Society in 1906, citing 
quadrillum as only a blacker form of vexatrix.
