6. Blapstinus dilatatus. 
Blapstinus dilatatus, Lec. Ann. Lyc. New York, v. p- 146°; Horn, Rev. Ten. N. A. p. 853’. 
Hab. Norra America, Colorado valley 1, Arizona ?.:—Mexico, Northern Sonora (Mor- 
rison). 
7. Blapstinus errabundus. 
Oblong ovate, convex, dull brownish black, when fresh somewhat thickly clothed with recumbent golden or 
brownish hairs. Head closely and rather coarsely punctured; prothorax convex, strongly transverse, 
widest at the base, narrowing anteriorly, the sides feebly sinuate behind the middle, base strongly 
bisinuate, anterior angles not very prominent and obtuse, hind angles prominent, directed backwards, and 
subacute, closely and rather coarsely punctured, the punctures not confluent ; elytra convex, widest about 
the middle or towards the base, regularly punctate-striate, the punctures shallow and rather fine, the 
interstices flat and finely and closely punctured ; legs reddish brown ; anterior tibiz similar in both sexes. 
Beneath slightly shining, finely and sparingly punctured. 
Length 53-6 millim. (¢ 9.) 
Hab. Mexico, Tuxtla (Sallé); Nicaragua, Chontales (Janson); Panama, San Lorenzo, 
Pefia Blanca (Champion). 
A few examples. Of the size and form of B. brevicollis, Lec., from California, but 
narrower, more convex, not so dull, and the thorax not confluently punctured. Closely 
allied to B. brunnipes, Dej., from Cayenne; the thorax more distinctly and not so 
finely punctured. 
8. Blapstinus insularis. 
Allied to B. errabundus, and differing as follows :—Rather more convex; the prothorax rather narrower, not 
so broad at the base, widest about the middle, the sides nearly straight towards the base, the anterior 
angles more prominent and less obtuse, rather more coarsely punctured; the elytra rather more convex, 
widest almost behind the middle, the strie more deeply impressed (the punctures, however, are not 
coarser), the interstices feebly convex and more coarsely and not so closely punctured. 
Length 6 millim. (2.) 
Hab. Panama, Taboga Island (Champion). 
One example. 
9. Blapstinus umbrosus. 
Oblong ovate, rather convex, black, subopaque, clothed with recumbent dark brownish hairs. Head coarsely 
and closely punctured ; prothorax broader than long, widest at the base, narrowing a little anteriorly, 
slightly rounded at the sides, the angles not very prominent, apex feebly emarginate, base feebly bisinuate, 
very closely, equally, and rather finely punctured, the punctures here and there confluent ; elytra shal- 
lowly, finely, and regularly punctate-striate, the punctures subtransverse, the interstices flat towards the 
suture, feebly convex towards the sides, indistinctly wrinkled transversely, finely, irregularly, and rather 
sparingly punctured ; legs black ; anterior tibiee similar in both sexes. 
Length 5-6 millim. (d 2.) 
Hab. Mexico, Northern Sonora (Morrison). 
Many examples received from the late Mr. Morrison as B. pulverulentus, Mann.; these 
do not agree with either of the two or three N orth-American species standing under that
