270 RHYNCHOPHORA. 
and deep towards the sides, the outer interstices feebly convex and each with an irregular row of very 
minute scattered punctures. First ventral segment depressed down the middle in the ¢. Legs stout, 
rugulosely punctulate ; femora each with a minute tooth. 
Length 3-33, breadth 13-13 millim. 
Hab. Guatemata, Capetillo, Duefias (Champion). 
In this insect the scutellum is not visible, the elytra are inflated for the greater 
part of their length, the prothorax is very convex, and the legs are stout, the femora each 
armed with a minute tooth; the seriate punctures on the elytra (as in O. piliferus) 
become much coarser towards the sides. Hight specimens. 
5. Oopterinus sxneopiceus, sp. n. 
Moderately elongate, shining, zeneo-piceous, the antenne and legs in part ferruginous; sparsely clothed with 
rather long, adpressed, yellowish-white hairs. Head convex, rather sparsely, somewhat coarsely punctate, 
sulcate between the comparatively large eyes; rostrum very stout, curved, shorter than the prothorax, 
rugosely punctured and longitudinally wrinkled. Prothorax much longer than broad, gibbous anteriorly 
and much narrowed behind, coarsely and confluently punctured at the base, and also coarsely punctured 
at the apex, the rest of the surface very sparsely, finely punctate. Scutellum not visible. Llytra ovate, 
barely twice the length of the prothorax, gibbous anteriorly and thence rapidly declivous to the apex, 
narrowing from about the basal third; coarsely punctate-striate at the sides, the punctuation becoming 
very fine and simply seriate on the disc, the setigerous interstitial punctures extremely minute. Femora 
each with a minute tooth. 
Length 23, breadth 1 millim. 
Hab. Mexico (Flohr, in Mus. Berol.). 
One specimen. Smaller than 0. gibdipennis, the general coloration brassy, the elytra 
relatively shorter, more gibbous anteriorly (this being especially noticeable when the 
two insects are viewed in profile), and rapidly narrowing and declivous from about 
the basal third. 
6. Oopterinus levigatus, sp.n. (Tab. XIV. figg. 2, 2a.) 
Moderately elongate, shining, eneo-piceous, the femora and tibie broadly annulated with testaceous, the 
antenne testaceous, with the club slightly darker; glabrous above, the legs and under surface clothed 
with a short, fine, scattered pubescence. Head convex, coarsely, closely punctate, depressed and smoother 
at the sides above the eyes, which are prominent and rather small; rostrum stout, curved, about as long 
as the prothorax, rugosely punctured and longitudinally wrinkled. Prothorax longer than broad, convex, 
rounded at the sides anteriorly, narrowed and constricted behind, the hind angles rectangular; closely 
and somewhat coarsely punctured at the base, the rest of the surface with very minute, scattered punc- 
tures. Scutellum invisible. Elytra moderately convex, two and one-fourth times the length of, and in 
their widest part about one-half broader than, the prothorax; almost smooth, the usual seriate punctures 
just visible towards the suture. Legs stout, finely punctulate; anterior femora with an extremely 
minute tooth. 
Length 4, breadth 14 millim. (9 ?) 
Hab, Mexico, Chilpancingo in Guerrero 4600 feet (A. H. Smith). 
One specimen. ‘The elongate shape, the moderately convex, almost smooth, and 
glabrous prothorax and elytra, and the annulate legs, distinguish this species at once 
from its allies.
