HETEROMERA. 529 
19 (s). Blapstinus puncticollis. 
Elongate, subparallel, rather depressed, very sparsely pubescent, shining black, the front of the head, oral 
organs, antenne, and legs ferruginous. Head coarsely, densely punctate, the eyes large ; prothorax strongly 
transverse, moderately convex, the sides parallel behind, gradually converging in front, the base bisinuate, 
the hind angles rectangular, the apex feebly emarginate (subtruncate if viewed from above), the anterior 
angles sharp but not prominent, the surface very coarsely, closely punctate, the punctures a little more 
scattered on the middle of the disc ; elytra the width of the prothorax at the base, parallel in their basal 
half, moderately elongate, flattened on the disc, with rows of coarsish, approximate punctures placed in 
very shallow stric, the interstices flat, feebly convex towards the sides and apex, each with one or two 
irregular rows of fine punctures ; beneath black, the flanks of the prothorax and the epipleure obscure 
ferruginous ; wings well developed. 
Length 53 millim. (¢.) 
Hab. Mexico, Amula in Guerrero (H. H. Smith). 
This small species, of which we have received only a single abraded example, is 
allied to B. atratus, but it is larger and more shining; the antenne and legs are 
ferruginous, the head and thorax are much more coarsely punctured, and the eyes are 
considerably larger. The punctuation of the thorax is unusually coarse, the punctures 
separate one from another. 
19 (c). Blapstinus exiguus. 
Elongate-oval, black or pitchy-black, slightly shining, sparsely pubescent. Head densely, rather coarsely 
punctate, the eyes small; prothorax strongly transverse, moderately convex, very little wider at the-base 
than at the apex, the sides rounded at the middle and obliquely converging in front and behind, the base 
bisinuate, the hind angles rectangular, the apex feebly emarginate, the anterior angles rather obtuse, the 
surface punctured like that of the head, the punctures here and there showing a tendency to become 
coalescent; elytra a little wider than the prothorax at the base, moderately elongate, slightly rounded at 
the sides in the female, more parallel in the male, with rows of rather fine, approximate punctures placed 
in shallow striz, the interstices flat on the disc, feebly convex towards the sides and apex, and each with 
one or two irregular rows of fine punctures ; legs piceous ; anterior tarsi scarcely dilated in the male; 
wings rudimentary. 
Length 4-43 millim. (3 Q.)_ 
Hab. Mexico, Tehuantepec (Hége). 
Numerous examples. This small species approaches J. atratus; it has the thorax 
narrowed behind, and very little wider at the base than at the apex. 
NOTIBIUS (p. 182). 
If we follow Capt. Casey’s revision of the genera of this group (Ann. N. York Acad. 
v. p. 499), our two species, V. rugipes and N. affinis, should be transferred to Conibius. 
Notibius affinis (p. 132). 
To the Mexican locality given, add :—Huitzo in Oaxaca (Hoge).
