1380 HETEROMERA. 
coarsish hairs. Head coarsely and closely punctured ; prothorax transverse, widest about the middle, the 
sides rounded and feebly sinuate before the base, anterior angles obtuse, hind angles rectangular, the base 
bisinuate, coarsely but not very closely punctured, the punctures not confluent, the disc darker in colour ; 
elytra comparatively short, convex, regularly and very coarsely punctate-striate (almost sulcate), the 
interstices towards the suture moderately, towards the sides strongly, convex, sparingly but distinctly 
punctured, scutellar stria deeply impressed ; antenne stout; legs stout, reddish brown, the inner half of 
the femora darker, anterior tibie similar in both sexes. 
Length 4-44 millim. (¢ 92.) 
Hab. Guatemata, Zapote, Las Mercedes (Champion). 
Four examples. A small, comparatively short, and convex species, with stout legs 
and antenne, the thorax coarsely punctured, the elytra coarsely and deeply punctate- 
striate, the interstices of the elytra strongly convex towards the sides. Smaller and 
shorter than B. egenus, the striz more deeply impressed and more coarsely punctured, 
the interstices convex. 
16. Blapstinus nitidus. (Tab. VI. fig. 15, ¢.) 
Elongate oval, moderately convex, black, shining, glabrous. Head coarsely and closely punctured ; prothorax 
transverse, widest at the base, narrowing anteriorly, the sides slightly rounded and feebly sinuate before 
the somewhat prominent but obtuse angles, the apex broadly but feebly emarginate, the base 
feebly bisinuate, coarsely but not very closely punctured, the punctures not confluent ; elytra regularly 
punctate-striate, the punctures rather coarse and elongate, the interstices flat and sparingly and finely 
punctured ; legs black; anterior tibic in the male abruptly widened on the inner side from the middle to 
the apex, strongly emarginate towards the base. 
Length 4-43 millim. (¢ 2.) 
Hab. Muxico, Jalapa (Hége). 
Two examples. This small species may be known by its elongate and convex 
form, the shining and glabrous surface, and the structure of the anterior tibie in the 
male. 
17. Blapstinus longipennis. 
Elongate oval, subparallel, moderately convex, brownish black, slightly shining, sparingly clothed with 
cinereous pubescence. Head coarsely and rather closely punctured; prothorax strongly transverse, 
widest at the base, very slightly narrowing anteriorly, the angles not very prominent, the apex feebly 
emarginate, the base very feebly bisinuate, the sides slightly rounded, the dise feebly impressed just before 
the base, rather coarsely but not very closely punctured, the punctures separate ; elytra more than twice 
as long as the prothorax, subparallel, regularly, closely, shallowly, and rather coarsely punctate-striate, the 
interstices flat and rather coarsely but not very closely punctured ; legs brownish black, the knees paler. 
Length 6-64 millim. (¢ ¢.) 
Hab. Mexico, Presidio (forrer). 
Allied to but probably distinct, judging from the description, from B. longulus, Lec. ; 
larger, longer, more convex, and more shining than B. atratus, the sides of the thorax 
more rounded and the hind angles more obtuse, the interstices of the elytra more 
distinctly punctured.
