84 Mr. G. C. Champion’s Notes on 
*Laemophloeus quadridentatus, n. sp. (Plate III, fig. 7, 3.) 
Oblong-ovate, rather broad, flattened, feebly shining, closely, 
finely pubescent; testaceous, the head and the disc of the thorax, 
and the last three joints of the antennae (the eleventh pale in one 
specimen), more or less infuscate, the elytra with a common, large, 
subtriangular patch, a broad angulate median fascia, and the apex 
fuscous, the legs testaceous ; the entire upper surface densely, minutely 
punctate. Head broad, short, obliquely depressed on each side ante- 
riorly, the labrum transverse; eyes very large, coarsely facetted ; 
antennae about half the length of the body, joints 3-8 slender, grad- 
ually becoming shorter and stouter outwards, 9-11 abruptly widened, 
9 and 10 transverse, 11 ovate, as long as 9 and 10 united, and 
constricted at the middle. Thorax broad, strongly transverse, 
somewhat rounded at the sides, the latter explanate, undulate, and 
strongly, equally crenate, the disc with a very prominent oblique 
ridge on each side, limited inwards by a shallow groove, the hind 
angles sharply rectangular. Elytra broader than the thorax, 
arcuato-explanate at the sides, and (viewed laterally) distinctly 
tricostate, the suture also a little raised posteriorly. Femora clavate, 
tibiae and tarsi slender. 
Var. Antennae entirely rufo-testaceous, the testaceous markings of 
the elytra more extended, and not interrupted by the costae, which 
are less prominent. 
Length 12-1? mm. 
Hab. Guaremata, Livingston and Trece Aguas (Barber 
and Schwarz, in U.S. Nat. Mus.). 
Five specimens, three paler than the others and with the 
elytra somewhat differently marked. In the dark form 
the testaceous portions of the elytral surface are clothed 
with cinereous pubescence, which accentuates the light 
markings, these being interrupted by the costae and ap- 
pearing as oblong streaks. The undulation of the thoracic 
margin forms four equidistant teeth, one of which represents 
the anterior angle. In the paler form the oblique testace- 
ous elytral fascia is broader and almost uninterrupted. The 
hind tarsi appear to be 4-jointed in the male.
