128 HETEROMERA. 
name in Mr. F. Bates’s collection, nor with the description of that species. Smaller 
duller, and narrower than B. pratensis, Lec.; the base of the thorax straighter, and the 
hind angles less prominent; the strie more lightly impressed and more finely and less 
regularly punctured, the interstices less regularly punctured and slightly wrinkled 
transversely. 
From the other species here recorded this species may be known by the very closely 
and rather finely punctured thorax, and by the dark brownish pubescence of the 
upper surface. 
10. Blapstinus palmeri. 
Of the size and form of B. umbrosus, and differing as follows :—The prothorax not quite so closely punctured, 
the punctures of the striz not so fine and more distinct one*from another, the interstices flat and finely 
and closely punctured ; not so dull, brownish black or black, the upper surface clothed with a cinereous 
or light brown pubescence. . 
Length 53-6 millim. (¢ 9.) 
Hab. Mexico, San Pedro and Monclova in Coahuila, Guajuco in Nuevo Leon 
(Dr. Palmer). 
Several examples. 
11. Blapstinus substriatus. 
Blapstinus substriatus, Laferté, in litt. 
Blapstinus anthracinus, Sturm, in litt. 
Oblong ovate, moderately convex, black, slightly shining, sparingly clothed with fine cinereous recumbent 
hairs. Head coarsely and closely punctured; prothorax strongly transverse, widest a little before the 
base, the sides slightly rounded and almost straight before the base, angles rather obtuse, apex feebly 
emarginate, base feebly bisinuate and the usual oblique fovea on each side lightly impressed, very closely 
and rather coarsely punctured, the punctures more or less confluent ; elytra regularly and finely punctate- 
striate, the strie narrowly and lightly impressed, the interstices flat and closely and rather coarsely 
punctured; legs black ; anterior tibie similar in both sexes. 
Length 44-53 millim. (¢ 2.) 
Hab. Mexico (coll. F. Bates), Puebla, Toluca, Guanajuato (Sallé), Jalapa (Hoge), 
Valle del Maiz, San Luis Potosi, Parras in Coahuila (Dr. Palmer). 
Locally common in Mexico. Allied to the North-American B. pulverulentus, Mann. ; 
the thorax shorter and more transverse, and the strize of the elytra finer and more lightly 
impressed. From B. mestus, Melsh., the species may be known by the less produced 
hind angles of the thorax, &c. 
12. Blapstinus buqueti. (Tab. VI. fig. 17, ¢.) 
Blapstinus buquetii, Laferté, in litt. 
Blapstinus puberulus, Klug, in litt. 
Elongate oval, moderately convex, dull brownish black, rather densely clothed with coarse brownish recumbent 
hairs. Head rather coarsely but not very closely punctured ; prothorax transverse, widest at the base, 
the sides slightly rounded and feebly sinuate before the not very prominent angles, apex rather deeply
