Host plants: decaying stumps of the genus Pinus. 
Type locality: Carolina. 
Type locality: lunulatus Swed., “Cape of Good Hope.” 
In recent catalogues lunata Fab. has been placed as a synonym of 
lunulatus Swed.; but, since we have been unable to find a satisfactory 
explanation for this interpretation in the literature, we are retaining the 
name lunata Fab. 
(6) Typocerus sparsus Lee., 1878, Proc. Am. Phil. Soc., vol. XVII, p. 614. 
Length 6 to 8 mm. This species is easily recognized by the characters 
given in the key. 
Twenty-seven specimens are before us from Ontario, Quebec, and 
Manitoba. Other localities in literature: Michigan, lake Superior, Wis- 
consin, and Ohio. 
Type locality: Escanaba, lake Superior. 
(7) Typocerus balteatus Horn, 1878, Trans. Am. Ent. Soc., vol. VII, p. 55. 
Length 9 to 10 mm. This species is distinguished by the yellow elytra 
marked with narrow, transverse, black bands, and the characters given in 
the key. The abdomen is in some cases reddish; the legs are reddish or 
partly blackened. 
Six specimens have been examined from “North West Territories,” 
Alberta, and Utah. Other localities in literature: Colorado, Montana, and 
Arizona. 
Type locality: “Occurs in Colorado (Morrison) and Arizona (Fuller).” 
(8) Typocerus brunnicornis Lee., 1873, Smith. Misc. Coll., No. 264, p. 214. 
Length 10 to 13 mm. A more slender species than balteatus Horn, 
black with indistinct pale pubescence, the antennae, abdomen, and tarsi, 
in some cases ferruginous. The single male before us has the antenna 
notably stout, strongly serrate, with large poriferous areas on segments 6 
to 11; the pronotum with sides on basal two-thirds nearly parallel, sub- 
inflated in front and strongly narrowed to the apex; the disk strongly 
inflated, moderately, not densely, punctate, the interstices shining, pubes- 
cence pale, denser at anterior and basal margins; elytra strongly cuneate, 
punctures deep, moderate in size and density; black with four, transverse, 
yellow bands, wider towards the suture which they do not quite attain; 
1st, basal, widest towards the scutellum, interrupted at the humeri; 2nd, 
postbasal, of moderate width; 3rd, postmedian, much narrower except 
towards suture; 4th, anteapical, reduced to a spot near the suture; the 
apices feebly truncate with the outer angles strongly rounded; last two 
dorsal segments shining, feebly punctured and indistinctly pubescent, 
last segment impressed at the apex; last ventral segment broadly, feebly 
impressed at the apex. 
One specimen before us from El Paso county, Colo., agrees most 
closely with the third specimen in the Leconte collection, from Utah. Only 
this, the type series, and three under sinuatus in the Leconte collection 
have been studied by the writers. The type has the antennae, legs, and 
margins of the elytra reddish, and the antennae slightly stouter. 
Distribution in literature : Colorado, Texas, New Mexico, and Florida. 
Type locality: Texas.
