lar stria,and the base of the sutural stria are somewhat 
confused. 
111. Chetocnema opacula, n. sp.—Elongate-oval, convex, elytra 
wider than the prothorax, dark black bronzed. Head opaque, impunc- 
tured. Prothorax transverse, not narrowed in front, sides broadly rounded, 
front angles not truncate ; surface opaque, finely, densely punctured, base 
with an indistinct row of punctures. Elytra moderately shining, strie 
composed of punctures of moderate size, not closely set. outer strize im- 
pressed. Base of antenne brown, legs dark. Length 1.5 mm.; .06 inch. 
California, Gilroy ; one specimen, Mr. G. R. Crotch. The 
antenne are broken and but two basal joints remain. 
112. Cheetocnema flavicormis, n. sp.—Oval, convex, dark 
bronze, not very shining, antennze yellow, scarcely darker at the outer ex- 
tremity. Head smooth, with the usual impressions. Prothorax finely 
punctured, narrowed in front of the middle, post apical angle distinct ; 
there is also a basal puncture each side opposite the base of the 6th stria. 
Elytral strise composed of small, close-set punctures, mterspaces obsoletely 
punctulate. Length 1.4 mm.; .055 inch. 
Detroit, Michigan; one specimen. Easily known by the 
small size, robust form and yellow antenne. The legs are 
dark, and the ventral segments sparsely punctured. The 
obliquely cut front angles of the prothorax and the basal 
puncture indicate a tendency toward Crepidodera. 
113. Chetocnema obesula, n. sp.—Still smaller, oval, convex, 
black bronzed, uot very shining, antenne and legs dark. Head smooth, 
with the usual impressions. Prothorax transverse, sides oblique, narrowed 
in front, surface alutaceous, obsoletely punctulate ; base finely margined 
with a transverse row of punctures. Elytral striz: composed of large 
strongly impressed punctures, interspaces slightly convex, smooth. Ab- 
domen nearly smooth, slightly punctured at the sides and tip. Length 1.2 
mm.; .05 inch. 
Lake Ashby and Baldwin; two specimens. 
114. Chetocnema decipiens, n. sp.—Narrower and less regu- 
larly oval, bronzed black, tibiz, tarsi and antennee testaceous, the last 
slightly brown at the extremity. Head smooth, with the usual impressions. 
Prothorax transverse, not narrowed in front, sides very slightly rounded ; 
post-apical angle somewhat distinct, with a very long seta; disc punctured. 
Elytra a little wider than the prothorax, striz impressed, punctured, inter- 
spaces convex, smooth. Abdomen nearly smooth. Length 1.5 mm.; .06 
inch. 
Kansas, one specimen. Of the same form as C, pulicaria
