72 Mr. G. C. Champion’s Notes on 
moderately large, nearly as long as the preceding four joints united, 
11 abruptly truncate at the tip. Anterior tibiae (fig. 4a) rounded 
at the apex externally. Tarsi moderately slender, joint 3 deeply 
excavate above. 
Length about 1 mm. 
Hab. GUATEMALA, Zapote, Pacific slope (Champion). 
Two examples. Easily separable from C. aciculatus by 
the polished upper surface, the widely scattered excessively 
minute punctuation of the elytra, the pale testaceous 
antennae, with abruptly truncate club, the rounded outer 
apical angle of the anterior tibiae, and the stouter tarsi. 
This insect has exactly the facies of a minute Agathidium, 
and it was placed among the Silphidae when our collections 
were sorted. 
*Cybocephalus schwarz, n. sp. 
Subrotundate, very convex, shining, glabrous above, black or 
bronze-black, the antennae testaceous, the club and basal joint 
sometimes infuscate, the legs fusco-testaceous; the thorax and 
elytra with widely scattered excessively minute punctures, which 
become more distinct and more closely placed on the apical 
declivity. Antennal club abruptly truncate at the tip. Under 
surface alutaceous, closely, minutely punctate, pubescent. Anterior 
tibiae rounded at the outer apical angle. Tarsi moderately slender, 
joint 3 deeply excavate above. 
Length 4-1 mm. 
Hab. Mexico, Tampico in Tamaulipas (Schwarz, in 
U.S. Nat. Mus.). 
Described from three examples. Two others from the 
same locality are larger and broader, and have the inter- 
spaces of the elytra distinctly alutaceous on the apical de- 
clivity; they are probably males of the same species. 
Another large example from Livingston, Guatemala, doubt- 
less belongs to C. schwarz. Extremely like C. flavicornis, but 
with the minute punctures on the elytra much more closely 
placed on the apical declivity. C. mgritulus, Lec., is un- 
known to me, but as the surface is described as “‘ laevis ”’ 
the present insect can hardly be conspecific with it. Some 
of the S. European forms, too, are also very similar to the 
present species.
