on the sides and towards the suture, so that an irregular, transverse black 
spot is enclosed; the median black band entire from suture to side margin; 
the third, postmedian, yellow band entire; the apical, fourth band black 
with a faint trace of an anteapical yellow band. The pygidium is distinctly 
emarginate.

caligans Csy., 1913, Mem. on the Coleop., p. 273. 
Length 9 to 13 mm. In our series of confluens, compared with the type 
series of six specimens, all gradations in colour of the elytra are represented 
from maculate to almost entirely black. This species is evidently the series 
spoken of by Leconte 1 under T. sinuatus as, “b, c, and d,” d? . 
The typical colour pattern of the elytra is black or brown, with four, 
transverse, yellow bands, variably broken into spots, the two median bands 
in some cases united at the suture. 
One hundred and forty-six specimens are before us from Kansas, 
Colorado, and South Dakota. 
Type locality: “Kansas and Colorado.”

arapahoe Csy., 1924, Mem. on the Coleop., vol. XI, p. 278. 
Length 10 to 12 mm. The colour pattern of the elytra was perhaps 
originally black with four, transverse, yellow bands; but the latter have 
become enlarged and fused along the suture, until in the majority of our 
specimens the elytra are yellow or reddish-yellow with a longitudinal row 
of four, lateral, black spots, the last apical, more or less united; in a few 
individuals, the last two pairs are variably fused across the suture. 
T. arapahoe Csy. is represented in the type series by three large speci- 
mens similar to sinuatus; but with the first black spots continuous across 
the dorsum to the suture, not united except at the extreme margin in one 
specimen. It is evidently sinuatus with the black spots more strongly 
developed laterally. Intergradations are suggested in our series. 
Two hundred and sixty-five specimens are before us from Montana, 
Illinois, Dakota, and Kansas, including eight pairs. Other localities in 
literature: Florida, Virginia, Indiana, Indian Ter., Texas, Colorado, 
Missouri, Nebraska, Louisiana, Maryland, Pennsylvania, Massachusetts. 
Type locality: St. John’s bluff, Florida. 
(14) Typocerus gloriosa Hop., 1922, Can. Ent., July, p. 166. 
Length 13 mm. The type of this very distinct species is a female; 
through an error in transcribing from the manuscript it was described as 
a male. 
The species is readily distinguished by the characters given in the key; 
the short front and very stout antennae are particularly striking, and the 
colours are unusually vivid for the genus. The body, legs, and antennae 
red, the elytra with alternate yellow and dark bands; 1st, basal, yellow,
