ANTHICUS. 249 
species of this section have a peculiar facies, owing to the short head and thorax and 
elongate comparatively broad elytra. The head is sparsely and minutely punctured and 
has a smooth central line; the occiput is not impressed. The antenne are short, very 
slender at the base, and thickened outwardly, the penultimate joints as broad as long ; 
the basal joints are testaceous, the apical joints infuscate. The thorax is scarcely so 
long as broad, very densely and minutely punctured, distinctly margined at the base. 
The elytra are rather convex, closely and coarsely punctured, the punctuation becoming 
very much finer towards the apex. The fifth ventral segment is truncate and unim- 
pressed in the male. Examples occur of a light reddish-brown colour. 
49. Anthicus teapensis, (Tab. X. fig. 28.) 
Moderately elongate, pitchy- or brownish-black, the prothorax sometimes ferruginous at the base and apex, the 
head and prothorax dull, the elytra moderately shining, the upper surface thickly clothed with fine decum- 
bent pubescence. Head strongly transverse, truncate behind, densely and minutely punctured and with 
a fine smooth central line, the occiput distinctly impressed, the eyes very large and moderately prominent ; 
antenne very short, about reaching the base of the prothorax, the penultimate joints transverse, testa- 
ceous, the three or four apical joints infuscate ; prothorax not quite so long as broad, much narrower than 
the head, moderately convex, narrowed at the sides behind and dilated at the base, the base very distinctly 
margined, the surface densely and minutely punctured; elytra rather convex, twice as wide as the pro- 
thorax, moderately elongate, subparallel in the male, a little more ovate in the female, truncate at the 
base, the humeri rounded, the base a little swollen on either side of the scutellum, the surface closely and 
coarsely punctured, the punctuation becoming very much finer beyond the middle; legs entirely testa- 
ceous; fifth ventral segment deeply foveate in the middle and truncate at the apex in the male. 
Length 23-23 millim. (¢ 9.) 
Hab. Muxico, Frontera and San Juan Bautista in Tabasco (Hége), Teapa in Tabasco 
(Hoge, H. H. Smith). 
This insect is not uncommon in the Mexican State of Tabasco, whence we have 
received numerous examples. A. teapensis is closely allied to A. fulvipes, La Ferté (an 
insect also occurring in Tabasco), but differs from that species in the head being densely 
and more minutely punctured, the occiput distinctly impressed, and the antenne shorter, 
the latter having the penultimate joints transverse; the fifth ventral segment is also 
deeply foveate in the male. In A. fulvipes the head is much smoother than the thorax ; 
in A. teapensis the head and thorax are almost equally densely punctured. 
50. Anthicus federatus. 
Moderately elongate, the head and prothorax ferruginous, piceous-brown, or piceous, the elytra piceous-brown, 
with the suture very narrowly darker; the head and elytra moderately shining, the prothorax dull; the 
upper surface clothed with rather long, fine, decumbent pubescence. Head transverse, convex, truncate 
behind, sparsely and minutely punctured, with a fine smooth central line, the occiput unimpressed, the 
eyes very large; antenne extending beyond the base of the prothorax, moderately slender at the base, 
‘thickening outwardly, the penultimate joints subtriangular, testaceous, the outer four or five joints usually 
infuscate ; prothorax as long as broad, narrower than the head, moderately convex, narrowed at the sides 
behind and slightly dilated at the base, the base distinctly margined, the surface very densely and minutely 
punctured ; elytra rather convex, twice as wide as the prothorax, moderately elongate, subparallel towards 
the base, the humeri rounded, the base a little swollen on either side of the suture and truncate, the
