298 HETEROMERA. 
b. Epipleure: abbreviated. 
19. Tarpela contigua. 
Oblong ovate, dull brownish-bronze. Head rather long, very closely, coarsely, and confluently punctured, 
shallowly transversely impressed in front; antenne (female) rather short, widening a little outwardly, 
black ; prothorax transverse, the sides rounded about the middle, a little narrowed and sinuate before the 
base and apex, the anterior angles slightly prominent though obtuse, the hind angles subrectangular, the 
apex rather shallowly emarginate, the base feebly bisinuate and with the central portion broadly but very 
slightly produced, the basal fovez shallow, the surface very closely, coarsely, and subconfluently punctured ; 
elytra much wider than the prothorax, narrowly margined, subtruncate at the base, the humeri rounded, 
rather convex, the sides almost straight from the base to the middle but widening a little beyond, with 
rows of deep, longitudinal, subconfluent impressions, the interstices feebly convex throughout, and not 
visibly punctured; legs (including the femora) coarsely and very closely punctured; beneath dull, the 
ventral surface finely, shallowly, and sparingly punctured and wrinkled, the flanks of the prothorax coarsely 
and confluently (though shallowly) punctured, the metasternum at the sides also (though not quite 
so coarsely) confluently punctured ; mesosternum feebly excavate ; prosternum declivous behind, the apex 
produced into a short conical tubercle; epipleure narrowed at the last ventral suture, thence narrowly 
extending to the apex. 
Length 73 millim. (2.) 
Hab. Mexico, Huetamo in Michoacan (Hége). 
One example. This insect resembles 7. jalapensis and T. hégei, but is duller ; the 
elytra are shorter and less parallel, and with feebly convex interstices; the thorax is 
punctured, and of very nearly the same shape as in 7. hégei, but with more pro- 
minent angles; the sides of the metasternum (as well as the flanks of the prothorax) 
are coarsely and confluently punctured; the prosternum as in 7’. jalapensis. 
20. Tarpela oblonga. 
Elongate ovate, subparallel, moderately convex, brownish-piceous, with a slight bronzy tinge, dull, scarcely 
shining. Head rather long, very closely and coarsely punctured, the punctures between the eyes still 
coarser and irregularly confluent, the usual transverse impression shallow, the epistoma rather long ; 
antenne rather long, in the male about reaching to the first third of the elytra, reddish-brown or piceous ; 
prothorax somewhat convex, subquadrate, rather broader than long, narrowly margined, widest at the 
middle, the sides narrowing a little behind and sinuate before the base, and slightly narrowing and feebly 
rounded from the middle to the apex, the apex rather shallowly emarginate, the anterior angles a little 
prominent, the base very feebly bisinuate, the basal fovez very shallow, the hind angles subrectangular, 
the entire surface coarsely, equally, and subconfluently punctured; scutellum with a few scattered rather 
coarse punctures; elytra considerably wider than the prothorax, long, subparallel to far beyond the 
middle, abruptly and obliquely narrowed at the shoulders, the humeri a little prominent in front and 
grooved within for the reception of the hind angles of the prothorax, with rows of rather coarse, closely 
placed, short longitudinal impressions, the impressions (including those of the scutellar row) deeper and 
confluent on the basal third of the disc, becoming a little coarser outwardly, and finer towards the apex, 
the sutural row from the middle finer, the interstices almost flat on the disc, a little convex outwardly, 
and sparingly and very finely punctured; tibiee coarsely roughened and punctured, the femora coarsely 
and more sparingly punctured; beneath shining, the ventral surface rather coarsely and somewhat closely 
punctured and also longitudinally wrinkled, the sides of the metasternum very coarsely punctured, the flanks 
of the prothorax very coarsely strigose; prosternum rounded off and strongly declivous behind, the apex 
slightly transversely raised; mesosternum rather shallowly excavate; epipleuree narrowed at the last 
ventral suture, thence very narrowly continued to the apex. 
Length 84-104 millim.; breadth 33-4 millim. (¢ Q.)
