southern part of the United States. None are yet re- 

 corded from Peru, Guiana, or Brazil.* 



CalUpogon barbatum, Fab. sp. Ins. I. 208. — This com- 

 mon Mexican insect occurs at Chontales as a local variety, 

 in which the largest male individuals have the short 

 thick mandibles of the medium developments of the 

 Mexican form. The antennae are also shorter. I am 

 inclined to think the original Fabrician description refers 

 to this form, obtained by Sir J. Banks from Honduras. 

 If so, the Mexican form should take the name of C. senex, 

 Dupont. Mag. Zool. 1832, pi. 33. 



Strongylaspis scobinatus, Thomson, Classif. des Ceramb. 

 p. 313; Chevrolat, Ann. Soc. Ent. Fr. 1862, p. 272.— 

 Several examples. Found also in Mexico and Cuba. I 

 have compared Chontales specimens with both Thomson's 

 and Chevrolat's types now in the British Museum. The 

 following appears decidedly distinct. 



Strongylaspis bullatus, n. sp. — Multo brevier, elytris 

 minus parallelus elongate subellipticus, fulvo-fuscus, pube 

 vel lanugine decufnbenti fulvo dense vestitus, thoracis 

 disco antico plagis duabus parvis, elevatis, nigro-castaneis 

 politissimis ; scutello gibboso asperrimo ; elytris, circa 

 scutellum solum, aspere granulatis ; antennis et pedibus 

 nigro-piceis. Long. 12 lin. S . 



One example in Mr. Belt's collection. 



* Six species are cited by Lacordaire (Genera, vol. viii. pp. 72-74); the 

 eighth is the following : — 



Braderochus inoequalis, n. sp. — c? Elongatus, castaueo-fuscus, antennis 

 corpore sexta parte brevioribus, thorace valde transverse, brevissimo, 

 utrinque trispinoso, spina mediana valde abbreviata, auteriori sub-bifida ; 

 elytris mox pone hvimeros explanato-dilatatis, apice late rotundatis utrin- 

 que bispinosis, supra coriaceis et punctulatis, humeris scabrosis, disco 

 leviter pluricostatis ; subtus sternis coxisque fulvo-pilosis. 



Long. 2 unc. ; lat. elytr. 7i lin. 



Hob. — Guatemala. Doct. Candeze amicissime dedit. 



By the sub-bifid form of the anterior thoracic spine, this species belongs 

 to the same section as Br. geminatus (Leconte), but it differs widely in 

 other respects ; the thorax is very much broader and shorter, and the 

 anterior spine does not project obliquely forward, besides being only im- 

 perfectly bifid, and the middle spine is reduced to a short tooth ; the 

 colour of the elytra is much darker, and they are less smooth and glossy ; 

 the two spines at the apex are nearer together. The antennas are of nearly 

 the same relative length. From Br. longicornis this species differs, besides 

 other characters, in the elytra being broadest a Little behind the shoulders, 

 ■where the margins are dilated and flattened out. In Br. longicornis they 

 are widest in the middle, and scarcely dilated.
