last ventral segment of the male is broadly emarginate. Only the type, 
male and female, in the National collection at Ottawa, and one in the col- 
lection of Mr. Ralph Hopping, are known to us. 
Type locality: Kaweah, Tulare county, California. 
(20) Anoplodera impura Lee., 1857, Ent. Rep., p. 64. 
Length 10 mm. A rather rare species of restricted distribution in 
high altitudes. The type was probably taken in the high mountains east 
of Sacramento, California; localities in those days in many cases being 
given as the nearest town. The last ventral segment in the male is truncate 
and broadly sulcate. 
Represented in the National Museum collection, Washington, by a 
pair from Sylvania, California; the female stouter with elytral spot pale 
but distinct, with its margin rather well defined, the male with the elytral 
spot small and indistinct. 
Three specimens have been before us from Fallen Leaf lake and Disco, 
California. Other localities cited in literature: Nevada and Oregon, 
Type locality: Sacramento, California.

Length 11 to 15 mm. This species may always be distinguished from 
the western laeta Lee. by its much more slender antennae. 
Twenty-six specimens were examined from Ontario, Quebec, Penn- 
sylvania, and Massachusetts. Other localities mentioned in literature are: 
New York, North Carolina, New Jersey, Illinois, Texas, Iowa, Georgia, 
and Colorado ( bellina Csy.). 
Host plants: Oak (Bland, Felt), Black oak (Horn), Castanea, Quercus 
(Craighead), Hicoria (J.M.S.).

reducta Csy., 1913, Mem. on the Coleop., vol. IV, p. 266. 
Length 10 to 12 mm. The basal transverse impression on the pro- 
notum is less deeply excavated, the vestiture shorter and sparse, the pro- 
thorax narrower and the basal angles less acute than in A. laeta , with the 
elytra more sparsely punctured at the base, and the pronotum of the male 
longer than wide. The type is a male. A. reducta Csy. is a smaller male, 
probably of the same species. Although probably breeding in oak, like 
nitens and laeta , tigrina is generally found on Mariposa lilies ( Calochortus ). 
Eight specimens were examined from Santa Barbara, Tulare, and 
Fresno counties, California. 
Type locality: Los Angeles, California.

Sacramento, California, to Victoria, British Columbia. On account of the
