various Central American Coleoptera. 85 
L. pictus, Schwarz, and L. parvulus, Grouv., which may 
prove to be synonymous: both were described in 1878. 
The N.-American L. vernalis, Lec., and L. pubescens, Casey, 
are unknown tome. The minute form now added is closely 
related to the Palaearctic L. sepicola, Miill. 
*Lathropus minimus, n. sp. 
Oblong-oval, depressed, opaque, piceous, the front of the head, 
the antennae (the club excepted), and legs ferruginous, almost 
glabrous. Head and thorax very densely, minutely, rugulosely 
punctate; antennae short, joints 1 and 2 stout, 3-8 slender, 3 as 
long as broad, 4-8 transverse, 9-11 stout, about as long as 3-8 
united, and forming a long, loosely-articulated club; thorax trans- 
verse, the lateral margins crenulate and moderately rounded, the 
hind angles acutely rectangular, the submarginal carina incon- 
spicuous, the disc transversely impressed or obsoletely bifoveate 
towards the base and apex. Elytra oblong, a little wider than 
the thorax, finely punctate-striate, the interstices rugulose, the 
disc shallowly depressed below the base. Beneath alutaceous, 
densely, minutely punctate. Legs very short. 
Length 1,4-14 mm. 
Hab. GuatEmALta, Zapote, Las Mercedes, Senahu (Cham- 
pron). 
A long series, all but two from Zapote. Very like L. 
sepicola, but much smaller, the elytra relatively narrower, 
the two shallow foveae on the disc of the thorax towards 
the apex indistinct. In L. minimus all the coxae are widely 
separated and the elytral epipleura extend rather broadly 
to the apex. . Viewed laterally, the alternate elytral inter- 
stices appear to be slightly raised. L. parvulus, Grouv., is 
described as ovate and rather convex, with an oblique 
Juteous mark on the anterior portion of the elytra. 
SALPINGOMIMUS, n. gen. 
Head short, broad, constricted behind, obliquely narrowed 
anteriorly, the small transverse epistoma limited posteriorly by a 
deep groove; eyes convex, very prominent; labrum transverse, 
exposed; mentum transverse; maxillae (fig. 8a) with two ciliated 
lobes ; maxillary palpi (fig. 8a) stout, joint 4 broadly oval, obliquely 
truncate at tip; last joint of labial palpi narrow, conical; mandibles 
short, bifid at tip; antennae free, stout, the last three joints widened 
and forming a distinct club, the preceding joints more or less monili- 
form; thorax constricted behind, immarginate laterally; scutellum
