HYMENORUS. 435 
23. Hymenorus depressus. 
Elongate, depressed, pitchy-testaceous, dull, thickly clothed with short pubescence. Head closely and not very 
finely punctured ; eyes large, narrowly separated; antenne short, the joints not much widened towards 
their apex, testaceous; prothorax broader than long, the sides almost straight behind and broadly rounded 
and narrowing in front, the hind angles subrectangular, the disc slightly depressed in the middle behind, 
the base feebly bisinuate, the surface finely and very densely punctured; elytra long, a little wider than 
the prothorax at the base, subparallel in their basal half, shallowly and rather finely punctate-striate, the 
punctures oblong in shape, the interstices finely and closely punctured ; legs slender, the first joint of the 
hind tarsi longer than the following joints united; beneath sparsely punctured. 
Length 5} millim.; breadth 2 millim. 
flab. Mexico, Chilpancingo in Guerrero (Hége). 
A single example, apparently a female. This insect very closely resembles the 
Californian H. confertus, Lec.; but may be at once distinguished from it by the 
larger and narrowly separated eyes (in H. confertus the eyes are widely separated, even 
in the male), and the less approximate and coarser punctures of the elytral striz. 
24. Hymenorus colonoides. (Tab. XX. fig. 4.) 
Oblong ovate, rather convex, piceous-brown, opaque, densely pubescent. Head closely and coarsely punctured, 
the anterior half and the oral organs ferruginous; eyes moderately large, transverse, about equally and 
not very widely separated in either sex; antennz short and stout in both sexes, ferruginous; prothorax 
broad, transverse, convex, the sides much rounded and converging from a little before the base, the base 
strongly bisinuate (the median lobe in consequence well defined), the hind angles subrectangular, the 
surface very densely and rugulosely punctured and almost unimpressed ; scutellum very closely punctured ; 
elytra moderately long, the width of the prothorax at the base (the sides forming almost a continuous 
outline with the prothorax), with rows of oblong moderately coarse punctures placed upon rather shallow 
strie, the interstices almost flat and finely and closely punctured ; legs short, ferruginous, the four hinder 
tibiee straight and similar in both sexes, the first joint of the hind tarsi not longer than the following 
joints united. 
Length 43-5} millim.; breadth 2-23 millim. (d 9.) 
Hab. Mexico, Guanajuato (Sallé), Atlixco, Matamoros Izucar, Jalapa (Hoge); Gua- 
TEMALA, Duefias (Champion). 
Numerous examples. Compared with H. americanus this species is easily distin- 
guished by the eyes being larger, more transverse, and less widely separated in both 
sexes ;‘ the thorax broader, as wide at the base as the elytra, the surface more densely 
and more coarsely punctured, and the base strongly bisinuate; the elytral strize more 
finely and more closely punctured, and the interstices rather flatter. This insect has 
much the facies of a species of Colon. 
95. Hymenorus brevipes. (Tab. XX. fig. 7, 6.) 
Closely resembling H. colonoides, and differing as follows:—Shorter and rather more convex; the eyes (¢) 
smaller and much more widely separated; the antenne (¢) much shorter, with the joints more widened 
towards their apex: the prothorax shorter and broader, more strongly transverse, still more rounded 
at the sides, the base strongly bisinuate and with the median lobe very prominent, the surface not quite
