finer behind, base nearly straight. The last ventral segment is truncate- 
emarginate in the female, deeply emarginate in the male. The second 
specimen in Leconte’s collection is possibly brevicornis } d? ; the third 
specimen is nigrella, 9 • 
Host plant: Populus trichocarpa. 
Type locality : “W.T” 
(2) Anoplodera brevicornis Lee., 1873, Smith. Misc. Coll., vol. XI, No. 264, 
p. 226. 
Length 14 to 19 mm. The following is the original description: 
“Nigra, sat robusta, opaea, capite dense, prothorace rude punctato, hoc campanulato, 
ad basin transversim profunde depresso, angulis posticis laminatis; elytris antice grosse, 
postice fortiter punctatis, apice oblique truncatis et breviter acmninatis; antennis (9) 
brevibus, extrorsum crassioribus, articulis 8-10 crassities haud longioribus. Long, 19 
mm. 
Virginia. City, Nevada; Mr, Edwards. Allied to L. nigrella Say, but much stouter, 
much more coarsely punctured, and with quite different antemue; the 3rd joint is two ana 
a half times as long as the 2nd, the 4th is two-thirds the length of the 3rd; the 5th is fully 
twice as long as the 3rd, the 6th and 7th shorter and wider, 8th, 9th, and 10th, stouter and 
shorter, almost wider than long, subtriangular, somewhat rounded, 11th la ger, oval, 
rather pointed. The total length barely extends beyond the base of the prothorax,” 
A female has been compared with the type ( 9 ) by Mr. C. A. Frost 
and later by the writers. The antennae are very short and stout, widened 
distally in the female; pronotum with sides faintly arcuate, gradually 
narrowed from the base towards the front, faintly constricted at the 
apical margin, the disk moderately convex, coarsely confluently punctured, 
densely on the sides, not so closely midway between the sides and the 
middle line which is impressed and closely punctured in front, elevated and 
smooth behind; elytra stout with sides subparallel in the female, coarsely 
and deeply punctate in front, confluently towards the scutellum, finely 
and closely on the caudal half, broadly emarginate at the apex. The male, 
as is usual, has the antennae much longer and strongly serrate; the last 
ventral segment is broadly emarginate. 
Six specimens have been examined besides the type, all from Cali- 
fornia, although Washington is mentioned in literature. Leconte cites the 
type locality as Nevada, but the type bears the label “Calif.” This species 
has been taken from old stumps of Abies magnified by Dr. F. E. Blaisdell. 
The second specimen in the Leconte collection under carbonaia , cf, 
“W.T.,” is possibly this species. 
Type locality: California (or Nevada?).

Length 13 to 19 mm. Say described the type as “brownish black,” 
probably from an immature specimen. The form praestans Csy. has 
testaceous or reddish elytra and an apical, black, lateral margin. On one 
specimen from lake Abitibi this black margin is nebulous, and another 
example has the black colour spreading nebulously nearly to the suture on
