528 SUPPLEMENT. 
The specimens from the northern part of our region agree with one from New 
Mexico forwarded by Capt. Casey; they are perhaps specifically distinct. Two males 
from Salazar, sent with a normal female of the typical form (1) from the same locality, 
are only 4 millim. in length; some of the Villa Lerdo specimens of the var. (2) 
measure 6 millim. 
Blapstinus egenus (p. 129). 
To the localities given, add :—Panama, Colon (Casey). 
17 (a). Blapstinus angustatus. 
Elongate, narrow, subparallel, pitchy-brown, shining, very sparsely clothed with long decumbent hairs. Head 
closely, rather coarsely punctate, the eyes large; prothorax transversely subquadrate, longitudinally 
convex, scarcely wider at the base than at the apex, the latter very deeply emarginate, the sides feebly 
converging in front, parallel from before the middle to the base, the anterior angles sharply produced 
and very prominent, the base bisinuate, the hind angles rectangular, the surface rather coarsely, closely 
punctate, the punctures sparser on the middle of the disc and separate one from another; elytra elongate, 
parallel, a little wider than the prothorax, with rows of coarse, deep, approximate punctures placed in 
shallow striz, the strie becoming deeper at the sides and apex, the interstices comparatively coarsely 
punctate, flat on the disc, convex towards the sides and apex; beneath coarsely punctured ; anterior tarsi 
densely clothed with spongy hairs beneath, and with joints 1-3 rather broadly dilated in the male; wings 
fully developed. 
Length 53 millim. (¢.) 
Hab. Mrxico, Tehuantepec (Hége). 
One example. Allied to B. longipennis, but much narrower than that insect; the 
thorax very deeply emarginate in front, almost parallel at the sides, moderately 
transverse, and with very prominent anterior angles; the elytra with series of coarse, 
deep, approximate punctures placed in shallow striz, the interstices rather coarsely 
punctate. More parallel and narrower than any of the other species described here. 
Blapstinus atratus (p. 131). 
To the localities given, add:—Mexico, Chilpancingo (H. H. Smith), Temax in 
North Yucatan (Gaumer). 
Sent in abundance by Mr. Gaumer. 
19 (a). Blapstinus fuscus. 
Blapstinus fuscus, Casey, Ann. N. York Acad. v. p. 427 (Nov. 1890) *. 
Hab. Nort Amurica, Texas !.—Muxico, Valle del Maiz (Dr. Palmer). 
A female specimen of a Blapstinus obtained by Dr. Palmer at Valle del Maiz agrees 
very nearly with a male of B. fuscus forwarded to me by Capt. Casey. B. fuscus 
resembles B. atratus, but has the anterior tarsi much more strongly dilated in the 
male.
