Length 14 mm. We are indebted to Mr. C. A. Frost for a female, 
collected at Sherbum, Mass., compared with the type of deleta Lee. The 
pronotum has the disk black, with the sides rufous and clothed with short, 
recumbent pubescence and in many cases with long, flying hairs, the 
median line rather narrowly impressed, sulcate and shining at the bottom; 
the elytra rufous, with the posthumeral, lateral, black spot very small and 
faint, a lateral, median, black spot of moderate size, well defined, and the 
apices dark and reddish at the tip; the abdomen red, except the lateral 
angles of the 1st segment, which are black. 
L. deleta Lee. is left for the present as a separate species, although it is 
difficult to separate our examples from the soror form of obliterata Hald., 
and it appears possible that, when a large number of examples of deleta 
are available, every gradation between deleta and obliterata will be found. 
Eight specimens examined, three of which are in the type series in the 
Leconte collection, and four in the Blanchard collection, three males and 
one female larger, with the elytra stouter, and the tips faintly marked.

var. lateralis Hald., 1853, ibid. 
Length 8 to 11 mm. The elytra of this species are testaceous with 
black, longitudinal vittse. The vittae are in some cases interrupted on the 
sides, causing rather curious effects in maculation which gave rise to Halde- 
mann’s varieties. The very slender form of lineola Say is aberrant among 
the North American species of the genus, approaching more closely some 
European species. 
Seventy-five specimens have been examined from Pennsylvania, New 
York, Massachusetts, and Ontario. In literature are cited the localities 
“Va.”, *‘Tex.”, “Md ”, “N.H ”, and “Ind.”, 
Host plant: Betula (Craighead),. 
Type locality: Pennsylvania. 
TYPOCERUS Leconte 
1850, Jour. Acad. Nat. Sci., vol. 1 (2nd ser.), p. 333. 
This group has been considered a subgenus of Strangalia Serv. by 
European writers; but the striking characters of the antennae and wings 
seem to us to merit generic distinction. 
Prosternum convex; pronotum trapezoidal with hind angles produced 
over the humeri; distal segments of the antennae with distinct poriferous 
areas; moderately stout species, with the elytra cuneiform; middle tarsi 
with 1st segment hardly longer than 2nd and 3rd united ; forecoxal cavities 
narrowly open behind; wing with closed cell in the radial sector stout and 
triangular. Genotype, (Leptura ) velutina Oliv.
