AcYPHODERES [Cerambycidae]. 

 Serville, Ann. de la Soc. Ent. de France, ii. p. 549. 



Acyplioderes brachialis. 



A. fuscus; capite prothoraceque sericeis, fulvo variis; eljiiris vitta fla- 

 vescenti; femoribus intermediis posticisqiie, basin versus, flavo annu- 

 latis, tibiis anticis intiis dentatis ; abdominis segmcnto penultimo dente 

 bifido instructo. 

 TTab. Brazil. 



Dark brown ; bead narrow and elongate, a patcb of yellow silky 

 hairs between the eyes, dividing into angular branches below them ; 

 prothorax ovate, nan'ower than the elytra at the base, covered with a 

 silky pubescence vaiied with four rather indistinct yellow stripes ; 

 scutellum narrowly triangular, pale yellow ; elytra extending to the 

 middle of the third abdominal seg-ment, pimctm'ed at the base, a yellow 

 vitreous stripe from near the base to the apex ; legs more or less hairy, 

 especially on the inner side of the intermediate and posterior tibioe ; 

 anterior tibife with a strong tooth beneath, near the middle; inter- 

 mediate and posterior femora annidated with yellow towards the base ; 

 body beneath dark brown shining, the metastemum varied with indi- 

 stinct patches of yellow silky hairs, abdomen elongate, very slender, the 

 basal segment naiTowest, the penvdtimate furnished with a broad bifid 

 tooth at its apical margin. Length 9 lines. 



The curious bilobed tooth beneath the abdomen is not, I think, a 

 sexual character, as might be supposed, as it also occurs in what 

 appear to be both sexes in one or two other species of this genus. 

 The abdomen is very miich attenuated at the base — a character which, 

 in the group to which it belongs, appears to be only of specific im- 

 portance. I have not seen any other species having the protibice 

 toothed. 



Hesthesis [Cerambycidae]. 

 Newman, Ann. Nat. Hist. v. p. 17 (1840). 



Hesthesis plorator. 

 II. uiger ; prothorace margine antica, elytrisque maciUa apicali tlavidis ; 

 abdomine supra, segmento primo basi tertioque apice, et infi-a tribus 

 primis flavo marginatis ; femoribus rufo-ferrugineis. 

 Hah. Molbounie. 



Black, with patches or lines of pale-yellow hairs ; a patch of yellow 

 hairs in the concavity between the eyes; prothorax subtransverse, 

 timiid at the side, closely punctured, the anterior margin bordered with 

 yellow hairs; scutellum black, triangidar ; elytra greyish brown, 

 lighter at the base, shoulder and an oblique line at the apex covered 

 with yellow hairs ; abdomen above with the first segment at the base, 

 margin of the third, and beneath the first three at the apices bordered
