78 Mr. G. C. Champion’s Notes on 
LAPETHUS. 
Lapethus, Casey, Ann. N. York Acad. Sci. vy, p. 317 
(1890); Sharp, Biol. Centr.-Am., Coleopt. 11, 1, p. 494 
(1895). 
In this genus the metasternal and abdominal lines are 
sharply defined, as in Lytopeplus. 
Lapethus sharpi, n.n. 
Lapethus discretus, Sharp, loc. cit. pl. 15, fig. 22 [nec 
Casey ]. 
Additional localities for this species are :— 
Mexico, Jalapa (Hdge) ; GUATEMALA, Coatepeque, Zapote, 
Capetillo (Champion), Jocalo, Lake Yzabal (Barber and 
Schwarz, nm U.S. Nat. Mus.). 
Apparently a common insect in Central America. The 
discovery of various allied forms with the lateral margins 
of the thorax deeply sulcate, so as to have a thick acute 
marginal bead, as described by Casey for L. discretus, shows 
that the Californian and Oregon insect cannot be conspecific 
with the Central American form figured under that name 
by Dr. Sharp, and a new name is therefore required for the 
latter.1_ The following species from Brazil is nearly related 
to L. sharpi. 
[Lapethus brasilianus, n. sp. 
Short, convex, oblong-elliptic, convex, shining, piceous, the 
antennae, mouth-parts, and legs rufo-testaceous. Head and thorax 
densely, finely punctate, the latter finely margined along the sides 
and feebly bisinuate at the base; elytra coarsely punctate-striate 
to the apex, the interstices rather convex and closely, minutely 
punctulate. Beneath smooth down the middle, conspicuously 
punctured in the femoral depressions, the metasternal and abdominal] 
lines sharply defined; prosternal process shallowly sulcate, extend- 
ing beyond the anterior coxae and received in a cavity of the meso- 
sternum. 
Length 12-2 mm. 
Hab. Brazit, Blumenau (ex coll. Sharp, in Mus. Brit.). 
Two specimens, one much larger and broader than the 
other. | 
! We have now received from the U. 8S. Nat. Museum an example 
of L. discretus, Casey, which is a very different insect.
