primis tarsisque, rufo-piceis ; elytris punctato-striatis, striis ad basin et ad apicem obliteratis, fasciis 

 duabus flavis, una basali, altera postmediana obliqua, latiore, subdenticulatis. Long. 7 millim. 



Eab. Panama, Volcan de Chiriqui (Bibbe). — Peru (coll. Gorham). 



This insect though evidently allied to B. fasciellus and its allies is less convex ; the 

 thorax especially is flatter, and it is entirely black. The body moreover is black, 

 instead of being, as usual in species of that sectioD, yellow or pitchy. The basal yellow 

 fascia of the elytra leaves the shoulder and a double spot near the scutellum black ; 

 the black portion between this and the postmedian fascia is much narrowed towards 

 the margin ; the epipleurse are yellow ; and the seven series of rather large punctures 

 are quite distinct. Only one example of this species has been received from Chiriqui, 

 and its antennae are almost entirely gone. I possess, however, two specimens of the 

 same species collected in Peru by the late Mr. Buckley, which only differ in being 

 slightly larger, and in one of them having a small pitchy spot on the thorax near the 

 front angles, while in the other the head is entirely black. 



5. Brachysphenus nuculus. 



Ovatus, convexus, nitidissimus, niger, abdomine elytrisque fulvis, ore rufo. Long. 8 millim. 



Eab. Mexico, Toxpam (Salle). 



The head and thorax are black and very shining ; the former is broadly impressed in 

 front, with the labrum and palpi rufous ; the antennas are black and as long as the 

 head and thorax ; the front margin of the latter is semicircularly excavate ; scutellum 

 black, partly covered by the median lobe of the thorax; elytra quite smooth and 

 without striae, although darker lines faintly indicate their position ; body and legs quite 

 black and smooth ; the prosternum compressed and elevated in front ; abdomen bright 

 red, of the same colour as the elytra. This species is coloured exactly like B, fulvi- 

 ventris, but is smaller and has precisely the form of a Megaprotus.

6. Brachysphenus cereus. 



Oblongus, parum ovatus, convexus, nitidissimus, lucide ochraeeus, fere glaber; antennis, pedibus, scutello, 

 palporum et mandibularum apicibus nigris, unguibus runs, elytris leviter et tenuiter punctato-striatis. 

 Long. 81-9 millim. 



Eab. Panama, Bugaba, Volcan de Chiriqui (Champion). 



Head a little produced, the epistoma distinct, very minutely punctured; labrum 

 distinct ; ocular striola and the puncture above the antennal socket well defined. 

 Antennae as long as or longer than the head and thorax, with a distinctly four-jointed 

 club, but the eighth and apical joints narrower than the ninth and tenth. Thorax 

 much narrowed anteriorly, the sides gently rounded, the front emargination deep, 

 nearly semicircular, but straight in the middle ; the basal margin bisinuate, its median lobe
