228 -RHYNCHOPHORA. 
2. Hypothenemus validus, sp. n. | 
Oblongus, subnitidus, niger, prothorace amplo, transverso, apicem versus subconstricto, disco medio nodoso, 
anterius tuberculis sat frequentibus ornato, margine antico bituberculato ; elytris punctato-striatis, 
interstitiis subconvexis, irregulariter subbiseriatim setis brevibus instructis. 
Long. 2 millim. 
Among the largest species of the genus; oblong, robust, slightly shining, black. Front moderately shining, 
subconvex, rather strongly punctured, thinly pubescent, with indications of a median tubercle; antenne 
testaceous, basal suture of the club transverse, the second curved. Prothorax transverse, subhemispherical, 
widest before the base, very slightly constricted anteriorly, the sides and apex conjointly rounded, 
the hind angles obtuse, the base subbisinuate ; disc ample, sprinkled with short fuscous-grey subsquamous 
hairs, with a well-marked nodose elevation in the middle, in front furnished with twenty or more 
rounded tubercles not extending to the sides, becoming closer and smaller towards the elevation, but not 
confluent nor forming transverse ridges, the anterior pair situated on the apical margin ; posterior half 
laterally subimpressed, uniformly and closely granulate-punctate. Scutellum transverse, triangular, 
subrugose. Elytra narrower than the greatest width of the prothorax and more than one-half longer, 
their basal borders slightly curved, the shoulders obtuse, the sides subparallel to beyond the middle, thence 
rounded to the apex; surface with rather shallow punctured striw, rather deeper behind, the interstices 
very slightly convex, not more so laterally, finely punctured in irregular rows, tending to become double, 
and bearing short blunt cinereous subsquamiform sete. Legs testaceous-brown, the femora usually 
infuscate. 
Hab. Mexico, Motzorongo in Vera Cruz (Flohr). 
One specimen. I have numerous others from tobacco-refuse. ‘The species is nearly 
allied to H. opacus (Eichh.), and is perhaps a mere variety. The examples before me 
differ from my solitary authentic specimen of that insect in their darker colour, and 
in the distinct nodose elevation of the disc of the prothorax, together with the much 
more prominent tubercles of its anterior portion. The elytral strie are also less 
impressed ; the interstices are more shining (where rubbed) and less convex, particularly 
towards the sides, and their rows of sete are less regularly uniseriate.

I have not seen any typical example of this species, and cannot identify it among 
our few unidentified Hypothenemi.

This species is quite unknown to me.
