Mr. G. C. Champion on various 



\'iit\ The elytra testaceous, with two blackish, abbreviated 

 or iiiterriipted streaks, one near the suture, the other sub- 

 marginal (var. armitagei, Pic). 



Length H-5,-„ breadth 2-1^ nun. {^ .) 



Hah. Brazil, Jatahy in (ioyas {Gounelle), Sao Paulo 

 {e.v coll. F)'i/). 



Pic's type, to judge from the briof note about it, would 

 appear to want the narrow !-sliaped streak extending down 

 the disc of each tlytron, conspicuous in the two males from 

 Jatahy before me. The variety, re|)resented by two examples 

 from Sao Paulo in the Fry Collection, agrees with his brief 

 diagnosis of A. armitagei.

^ . Antenna rather slender, elongate, n)uch longer than 

 in ? . Ventral segment 5 deeply arcuato-emargiiiate, 6 

 moderately long, subconical, with a narrow, deep, triangular 

 notch at tip. Tegraen with long lateral lobes, which are 

 rounded and clothed with long hairs at the apex. Pcnis- 

 sheath, as seen in profile, obliquel}^ dilated and subsecuriform 

 at tip. 



? . Ventral segment 5 feebly emarginate, 6 shaped very 

 much as in (J • 



Hab. Bolivia {Mus. Brit.: (^ ?), Chuquisaca [type] ; 

 ? Chile {Germain, ex coll. Fry :<??). 



Very like the variable A. quadrilineaius^ Germ., but with 

 much more finely j)unctured elytra, the apices without tooth 

 at the sutural angle in either sex ; the prothorax (in fresh 

 specimens) with a line down the middle and a space along 

 tlie sides closely cinereo-pubescent, much as in A. atro- 

 maculattiSj Blanch. ; theantennse long and slender in ($ , witii 

 tiie basal joints only te^^taceous ; the genital armature vevy 

 different. 



Five specimens are before me, including a pair from 

 Bolivia, a pair labelled "Chile" (a locality requiring con- 

 firmation), and a J, belonging to the Oxford Museum, 

 labelled ^^ quadiivitlatiis, Chevr., Andes." Melyris quadri- 

 i(tniata, Er., from Peru, may be based upon a slightly worn 

 example ot the present spe?,ies, the definition "elytris apice 

 integris, crebre punctatis, subrugulosis " agreeing with 

 A. vittatfcollis.
