AcypJioderes hracliialis. 



A. fuscus ; capite prothoracoque sericeis, fulvo variis ; elytris \'itta fla- 

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

 latis, tibiis anticis intus dentatis ; abdominis segniento penultimo dente 

 bifido instructo. 



Ilah. Brazil. 



Darlv brown ; head narrow and elonfjate, a patch of yellow silky 

 liairs between the eyes, dividing- into angular branches below them ; 

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

 silky pubescence varied with four rather indistinct yellow stripes ; 

 scutellum narrowly triangular, pale yellow ; elytra extending to the 

 middle of the third abdominal segment, punctured at the base, a yellow 

 vitreous stripe fi-om near the base to the apex 5 legs more or less hairy, 

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

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

 mediate and posterior femora annulated 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 nan-owest, the penultimate 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 much attenuated at the base — a character which, 

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

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

 toothed.
