various Central American Coleoptera. 83 
Two Central American species were referred to this genus 
by Lewis, who placed it in the Histeridae. Casey [Ann. 
N. York Acad. Sci. v, p. 318 (1890)] associates Murmidius 
with Lapethus, in his section “ Murmidiini”’ of the Coly- 
diidae, and this seems to me to be its proper position. 
The new form now added from N. E. Mexico is more 
elongate than the cosmopolitan M. ovalis, and entirely 
glabrous. The non-striate prosternal process, etc., dis- 
tinguish it from M. irregularis and M. rectistriatus. 
*Murmidius estriatus, n. sp. 
Oblong, shining, castaneous, the legs and antennae testaceous, 
glabrous; the upper surface somewhat closely, minutely, confusedly 
punctate, the punctures on the under surface widely scattered 
and excessively minute. Head rather small; thorax short, very 
gradually narrowed to the rounded anterior angles; elytra oblong, 
subparallel for some distance below the base, finely margined ; 
prosternal process very broad, arcuate-emarginate at the apex, 
sharply separated from the flanks, but without submarginal stria ; 
mesosternal process very broad, rounded in front, the marginal stria 
complete. 
Length 1} mm.

LAEMOPHLOEUS. 
Laemophloeus, Castelnau, Hist. Nat. Ins. Coleopt. i, 
p- 385 (1840); Sharp, Biol. Centr.-Am., Coleopt. 
ni, 1, p. 513 (1899). 
Dr. Sharp enumerated forty species of Laemophloeus from 
Central America, some of which have a very different facies 
from the type, L. monilis. The Guatemalan form now 
added should perhaps form the type of a new genus. It 
approaches Rhabdophloeus, but differs from it in having a 
broadly truncate intercoxal abdominal process. The last 
three joints of the antennae are much larger than the 
preceding joints, the elytra are tricostate, the anterior 
acetabula are open, and the upper surface of the body is 
densely punctulate and pubescent.
