(6) Leptura plagifera Lee., 1874, Smith, Misc. Coll., vol. XI, 224. 
Length 10 to 13 mm. This species is probably found only in the high 
mountains of the west. The disk of the elytra is generally black with a 
reddish testaceous margin; specimens with the elytra entirely black or 
entirely red are, however, not uncommon. The elytra are usually dis- 
tinctly costate. The abdominal segments are red in all our specimens. 
Fifty-two specimens examined from British Columbia and California 
south to San Barnardino, mostly from British Columbia. Other localities 
given in literature: Colorado, Nevada, Oregon, Idaho, Montana. 
Host plant: Pinus ponder osa (Craighead, Hopping). 
Type locality: lake Tahoe, California.

elegans Hald., 1853, Trans. Am. Phil. Soc., p. 63. 
Length 10 to 14 mm. The form elegans Hald. is the female and has a 
bicoloured pronotum; in the males that we have seen the pronotum was 
always black. Mr. Morris, of Peterborough, Ontario, has taken the two 
forms in coitu. The extent of black maculation on the elytra varies greatly 
in both sexes, some females having only a median triangular black spot and 
a very narrow black line on the sutural and lateral margins. 
Fifty-three specimens were examined from Pennsylvania, New York, 
Ontario, Quebec, and Nova Scotia. Other localities given in literature are, 
“NX”, “N.H.”, “Mich.”, “Va ”, “111.”, “Mass.”, “N.C.”, “Ind.” 
Host plants: Tsuga (Felt), Pinus (Craighead). 
Type locality: Maine. 
(8) Leptura plebeja Rand., 1838, Boston Jour. Nat. Hist., vol. 2, p. 28. 
Length 9 to 10 mm. Specimens are known with the elytra entirely 
black, or testaceous with black apices. The abdominal segments are usually 
red. 
Nineteen specimens have been examined from Massachusetts and 
Ontario. Other localities given in literature, “E. St.” (Eastern States), 
Michigan, L. Superior. 
(9) Leptura propinqua Bland., 1865, Proc. Ent. Soc. Phila., vol. 4, p. 384. 
regularis Csy., 1913, Mem. on the Coleop., p. 259. 
minuscula Csy., 1913, Mem. on the Coleop., p, 260. 
Length 8 to 14 mm. The antennse, legs, and prothorax are entirely 
black in this species and the hind legs very slender and somewhat longer 
than normal; hind legs 16 mm., body 13 mm. The testaceous elytra are 
regularly ornamented with a median, transverse, lateral spot, a post 
humeral spot, and the elytral tips black; a slender species, with slender 
antennae and legs. This is probably a distinct species, but many specimens 
can be distinguished from the form of obliterata Hald. known as soror Lee. 
only by colour and the somewhat more slender antennae and legs. Mr. 
Hopping has taken numerous pairs of each of these species and on no 
occasion was intennating observed. 
L. minuscula Csy. is represented in the type series by five males and 
one female, all small, with the pronotum rather more coarsely and sparsely
