B2 Mr. G. C. Champion’s Notes on 
*Lytopeplus tabialis, n. sp. 
Ovate, convex, shining, ferruginous, the legs and antennae testa- 
ceous. Head and thorax smooth, the latter deeply sulcate along 
the lateral margins and bisinuate at the base; elytra with rows of 
scattered fine, conspicuous punctures which become obsolete beyond 
the middle. Beneath smooth; metasternal and abdominal lines 
conspicuous; prosternal process moderately broad. ‘Tibiae short, 
broadly dilated. 
Length 2 mm. 
Hab. Nicaragua, Chontales (Janson). 
One specimen, in perfect condition, but somewhat imma- 
ture, labelled by Dr. Sharp long ago as belonging to his 
genus Lytopeplus. The regularly ovate shape and the short, 
broadly dilated tibiae distinguish this species from JL. 
sulcomargo and L. insularis. The thorax is rapidly arcuately 
narrowed from the base and the deep lateral sulcus extends 
forwards to near the apex. 
*Lytopeplus sulcimargo, n. sp. 
Brachylon breve, Gorh., Biol. Centr.-Am., Coleopt. vii, 
p. 207 (part.). 
Short, oblong-elliptic, convex, shining, piceous, the antennae, 
mouth-parts, and legs testaceous. Head and thorax almost smooth, 
the latter with a deep sulcus along the lateral margins and the base 
feebly bisinuate; elytra with rows of very fine, shallow, scattered 
punctures, which become coarser towards the sides and almost 
obsolete towards the suture. Beneath almost smooth; metasternal 
and abdominal lines fine, but conspicuous; prosternal process very 
broad. 
Length 14-2 mm. 
Hab. Nicaraaua, Chontales (Janson). 
Two specimens, one much larger than the other. The 
larger one was included by Gorham under his Brachylon 
breve, from which it differs in having the margins of the 
thorax deeply sulcate. L. sulevmargo is very like the 
Antillean ZL. insularis, Grouv. (Notes Leyden Mus. xx, 
p. 40, 1898), but it is less elongate and has smoother elytra.
