356 Mr. G. 0. Champion on various 



Var. The elytra testaceous, with two blackish, abbreviated 

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

 marginal (var. armitagei, Pic). 



Length 4^-51, breadth 2-2^ mm. (<£.) 



Hab. Brazil, Jatahy in Goyas (Gounelle), Sao Paulo 

 (ex coll. Fry). 



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

 appear to want the narrow !-shaped streak extending down 

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

 Jatahy before me. The variety, represented by two examples 

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

 diagnosis of A. armitagei. 



26. Astylus vittaticollis. 



Dasytes vittaticollis, Blanch, in Voyage d'Orbigny, p. 98 (1843). 



? Melyris quadritceniata, Er. Arcliiv fur Naturg. xiii. 1, p. 84 (1847). 



cJ . Antenna? rather slender, elongate, much longer than 

 in ? . Ventral segment 5 deeply aicuato-emarginate, 6 

 moderately long, subcorneal, witli a narrow, deep, triangular 

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

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

 sheath, as seen in profile, obliquely dilated and subsecuriform 

 at tip. 



$ . Ventral segment 5 feebly emarginate, 6 shaped very 

 much as in <$ . 



Hab. Bolivia (Mus. Brit.: <$ ?), Chuquisaca [type] ; 

 ? Chile (Germain, ex coll. Fry : <$ ? ). 



Very like the variable A. quadrilineatus, Germ., but with 

 much more finely punctured 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 

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

 maculatus, Blanch. ; the antennae long and slender in £ , with 

 the basal joints only testaceous ; the genital armature very 

 different. 



Five specimens are before me, including a pair from 

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

 firmation), and a <$ , belonging to the Oxford Museum, 

 labelled " quadrivittatus, Chevr., Andes." Melyris quadri- 

 taniata, Er., from Peru, may be based upon a slightly worn 

 example of the present species, the definition "elvtris apice 

 integris, crebre punctatis, subrugulosis " agreeing with 

 A. vittati 'colli s.
