22 - HETEROMERA. 
middle, rather coarsely, closely, and confusedly punctured, usual rows. of punctures obsolete ; legs rather 
long ; prosternum deflexed behind and slightly produced into a short, broad, horizontal projection trun- 
cated at the apex; mesosternum thickened into a rounded smooth elevation between the intermediate 
cox; ventral segments very finely and confusedly punctured towards the apex, the first segment smooth 
with scattered punctures. 
Length 114-123 millim. 
Hab. Mexico, Puebla (coll. F. Bates), Izucar and Puebla (Sailé). 
Four examples. This species may be known by the differently shaped prosternum. 
12. Schenicus vestitus. 
Oblong ovate, convex, dull dark bronze, covered with scattered short appressed cinereous hairs, when fresh 
completely clothed with a yellowish-white mealy efflorescence. Head closely and finely punctured, the 
epistoma not produced and feebly rounded and emarginate in front, the labrum in consequence appearing 
very prominent; prothorax broader than long, convex, widest at the base, the sides rounded and narrowing 
from the base, the hind angles rectangular, front angles obtuse not prominent, the base bisinuate, a 
shallow impression in the middle behind in front of the scutellum, closely and rather coarsely punctured, 
the punctuation closer and finer at the sides; elytra broader than the thorax, rather closely confusedly 
and somewhat coarsely punctured, and with shallow dorsal grooves, in each of which is an indistinct or 
interrupted row of coarser punctures; prosternum horizontal, a little concave, produced behind into a thin 
short lobe rounded at the apex; mesosternum a little thickened between the intermediate coxe, in some 
examples slightly concave in front and with a short indistinct blunt tubercle on each side. 
Length 9-11 millim. 
Hab. Mexico, Vera Cruz (Sallé), Oaxaca (Hoge). 
Found by Hége in some numbers. This species might be placed either in Schenicus 
or Epitragus, having some of the characters of both. 
18. Schenicus yucatanensis. 
Epitragus yucatecus, Deyr. in litt. 
Oblong obovate, convex, dark reddish brown, with fine scattered yellowish pubescence. Head closely and 
rather coarsely punctured, the epistoma emarginate in front; prothorax a little broader than long, convex 
in front, widest at the base, the sides rounded and narrowing from the base, hind angles subacute not 
prominent, anterior angles not prominent, the base bisinuate, very closely equally and rather coarsely 
punctured ; elytra wider than the thorax, widest behind the middle, with rows of shallow grooves obsolete 
at the apex, the interstices closely finely and confusedly punctured, the dorsal grooves each with an 
irregular row of slightly coarser impressions; the prosternum horizontal, a little produced behind, the 
apex rounded; the mesosternum rounded and declivous in front, not ridged or formed to receive the 
prosternum. 
Length 10 millim. 
Hab. Mexico (coll. F. Bates). 
One example. The structure of the pro- and mesosternum in this species is the 
same as in S. vestitus, from which, and from Epitragus emarginatus and E. salle 
(apart from the differently formed mesosternum), it may be known by its almost obovate 
form.
