Hab. Mexico (Mm. Brit.), Catemaco, Toxpam, Santecomapan (SallS), Misantla

Seven specimens, the localities enumerated 



being all in Vera Cruz. 



This species

resembles B. maculifer, Fahr.

subcylindrical and less swollen on each side towards the base, the scape shorter, the

spot on the disc of each elytron placed a little nearer the one at the shoulder (and 

 therefore more distant from the suture), and the metasternum somewhat flattened 

 anteriorly. From the Colombian B, quadripanctatus, the present insect may be 

 known by its narrower form, the subcylindrical, more slender rostrum, the different 

 arrangement of the velvety-black spots on the elytra, and the less thickened legs.

Subelliptic, robust, opaque, black, closely cinereo-pruinose, the scattered punctures on the prothorax 

 and those along each elytral interstice each surrounded by a denser cinereous dot, the elytra with a 

 common, large, v-shaped patch at about the middle, a complete, outwardly-widened, subapical fascia, 

 and a spot on the shoulder, velvety-black or brownish-black, the prothorax with indications of a 

 darker lanciform median vitta and an interrupted stripe on each side of the disc. Rostrum about as 

 long as the prothorax, very stout, moderately curved, and strongly indexed, sparsely, finely punctate, 

 bare at the apex, setulose and shallowly sulcate beneath, the peduncle of the submentum rounded at the 

 tip, the widened basal portion canaliculate. Antennse stout, pruinose throughout, the funiculus as long 

 as the scape, its outer joints strongly transverse. Prothorax broader than long, the sides rounded ante- 

 riorly and parallel at the base, the base deeply bisinuate ; sparsely, finely punctate, the disc with a very 

 shallow foveiform depression on each side at about the middle. Scutellum small, concave, oblong- 



Elytra finely punctate-striate, the interstices broad, flat, each with a row of small, 

 scattered, conspicuous punctures. Pygidium sparsely punctate, setulose at the tip. Beneath very 

 sparsely, finely punctate ; ventral depression broad, extending forwards to beyond the middle of the 

 metasternum. Legs stout, comparatively short ; femora fringed with rather long, the tibiae with short, 

 hairs ; third tarsal joint moderately large, spongy-pubescent in its outer half beneath. 

 Length KU-IU, breadth 4-44 millim.

Three examples, one coated with a brownish incrustation. Very near the Colombian 

 B. (Cactophagus) 4t-punctatus, Chevr., and the Peruvian B. (Sphenophorus) melanuru&j 

 Kirsch (the types of both of which I have seen), but differing from these insects in 



a large, common, v-shaped, velvety-black or dark patch on the disc of the 













having 

 elytra.

Somewhat fusiform, moderately elongate, robust, opaque, black, closely cinereo-pruinose, the scattered 

 punctures on the prothorax, elytral interstices, flanks, and femora each surrounded by a larger or smaller, 

 denser, cinereous dot, the prothorax with a lanciform median vitta and a space along the sides indeter- 

 minately darker ; the elytra with a common, large, v-shaped patch at about the middle, an interrupted 

 subapical fascia, an oblong patch at the shoulders, and the sutural region for some distance below the 

 base, velvety-brownish-black. Rostrum very stout, abruptly curved from the broader basal portion, 

 bowed at the tip in the 3 , finely punctate, setulose and shallowly sulcate beneath, the peduncle of the
