BLAPSTINUS. 125 
striate, the strie finely and shallowly punctured, the interstices flat, rather coarsely and distinctly but not 
very closely punctured ; legs reddish brown. 
Length 8 millim. ( 9.) 
Hab. Mexico (Sallé, ex coll. Sturm), Yucatan (coll. F. Bates). 
Two mutilated examples are all I have seen of this species. Labelled B. chevrolati, 
Pilate, in Mr. F. Bates’s collection. 
2. Blapstinus tibialis. (Tab. VI. fig. 19, 3.) 
Allied to B. mesxicanus, and differing as follows :—More convex; the thorax widest in the middle, longer and 
narrower, the sides distinctly narrowed and sinuate before the base, very little broader at the base than 
at the apex, anterior angles more prominent and subacute, hind angles subrectangular, more equally 
punctured, the punctures not confluent towards the sides; the elytra sculptured as in that species ; legs 
reddish brown; anterior tibie in the male slightly curved, swollen on the inner side about the middle, 
and narrowing at the base and apex. Beneath shining, rather coarsely punctured and wrinkled; in the 
male the metasternum and ventral surface towards the base longitudinally excavate in the middle. 
Length 7-8 millim. (¢ 9.) 
Hab. Guatemata, Zapote, El Reposo, Capetillo, El Tumbador (Champion); Nicaragua, 
Granada (Sallé). 
Rather common on the Pacific slope in Guatemala at elevations of from 2000 to 
4000 feet. B. tibialis may be known from the other described species of the genus by 
its convex form, the somewhat shining surface, the coarsely punctured interstices of the 
elytra, and the thickened anterior tibiee in the male. 
3. Blapstinus grandis. (Tab. VI. fig. 18, ¢-) 
Oblong ovate, convex, dark reddish brown, subopaque, sparingly clothed with recumbent brownish hairs. 
Head closely and coarsely punctured, the epistoma rather deeply emarginate ; prothorax convex, trans- 
verse, widest about the middle, the sides rounded and slightly sinuate before the base, anterior angles 
prominent and subacute, hind angles obliquely rectangular, base strongly bisinuate, closely and rather 
finely punctured, the punctures separate and finer than those upon the head, with an indistinct central 
groove; scutellum very ‘closely and finely punctured; elytra regularly punctate-striate, the punctures 
moderately coarse but not very deeply impressed, the disc slightly depressed, the interstices flat and finely 
and rather closely punctured, the apices slightly swollen and divergent; legs reddish brown; anterior 
tibie slightly curved in both sexes, slightly swollen from a little before the middle to the apex in the 
male, Beneath shining, finely and rather closely punctured; in the male the metasternum behind and 
the ventral surface (the first and second and the base of the third segments) broadly and deeply excavate 
longitudinally, and the last segment flattened, in the middle. 
Length 92-103 millim. (d 9 -) 
Hab. Nicaracua, Chontales (Belt, Janson). 
Apparently rather common at Chontales, and found in some numbers by the late 
Mr. E. Janson.
