CHETOCNEMA (p. 394). 
12. Cheetocnema smithi. | 
Dark zneous; the basal joints of the antennw, the four anterior legs, and the posterior tibia and tarsi fulvous, 
the posterior femora neous; head and thorax rather remotely punctured; elytra deeply purictate-striate, 
the interstices flat and impunctate. | 
Length 1 line. . 
Of rather elongate and robust shape; the head distinctly but not closely punctured ; the antenne rather short, 
the five lower joints fulvous, the others piceous, thickened ; thorax at least twice as broad as long, the 
sides but feebly rounded, with indications of a thickened angle before the middle, the anterior angles not 
_ oblique, the surface remotely impressed with somewhat oblong punctures, which are a little larger and 
more rounded in shape at the sides; elytra convex, pointed at the apex, very regularly and deeply 
punctate-striate, the interstices flat, except near the lateral margin, impunctate. a 
Hab. Mexico, Teapa in Tabasco (H. 11. Smith). 
A single specimen. C. smithi seems to be very closely allied to C. protensa, Lec., 
but in that insect the thorax at the base is only one third wider than long and the 
_ femora are all bronze (according to Horn); in the present.species the thorax is scarcely 
narrower in front than at the base. | -_ 
13. Chetocnema fulvilabris. | 
Obscure zeneous; the labrum, antenn, and legs fulvous, the posterior femora piceous; head impunctate ;. 
thorax finely and closely punctured; elytra finely punctate-striate, the interstices flat and impunctate. 
Length # line. 
‘Hab. Mexico, Omilteme in Guerrero (H. H. Smith). 
A single example. In this species the head is entirely impunctate, the labrum and 
antennz are fulvous, and the thorax, as in C. smithi, has not oblique anterior angles, 
the latter being, however, slightly thickened. It differs from C. smitht in having the 
thorax much more closely and finely punctured, and with a row of very fine punctures 
along the basal margin; the elytra are also more finely punctured, and the interstices 
are flat throughout. 
14. Chetocnema interstitialis. | 
Oblong-ovate, robust, dark bronze-coloured, the basal joints of the antenne, the tibie, and tarsi pale fulvous ; 
head and thorax strongly punctured ; elytra pointed at the apex, deeply punctate-striate, the interstices 
minutely punctured. ; 
Length 1 line. 
Head strongly but not very closely punctured, the clypeus rugosely punctate ; antenne extending to the base 
of the thorax only, black, the lower six joints fulvous; thorax twice as broad as long, the sides rounded, 
- without oblique angulation anteriorly, the surface deeply and closely punctured laterally, less closely so 
on the disc; elytra with regular and deeply punctured striz, the interstices extremely finely punctured, 
the punctures on each arranged in a single row; prosternum closely punctured, the abdomen more 
sparingly so. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). 
A single specimen. Of the same robust and comparatively broad shape as C. capitata
