AGRIOTES. 521 



carinate ; the surface densely, finely punctate, canaliculate at the base, and with a smooth median line ; 

 the base with a distinct incisure on either side ; the marginal carina distinct throughout. Elytra three 

 times the length of the prothorax, and equalling it in width, flattened on the disc, a little rounded at the 

 sides, and rapidly narrowing from about the basal third, pointed behind, the apices slightly acuminate ; 

 punctate-striate, the interstices somewhat convex, flat on the disc, and closely, rugulosely punctate. 

 Beneath (including the propleurae) densely, finely punctate, the prosternum with coarser and more 

 scattered punctures. Hind coxal plates a little widened in their inner third. 

 Length 8£-9£, breadth 2f-2| millim. 



Hab. Nicaragua (Salle), Chontales (Belt). 



Two examples, one of which is a female. Amongst the species described by Candeze, 

 the present one can only be compared with A. tceniatus, from which it differs in the 

 narrower, curved, paler vittae of the thorax, the thorax itself being much shorter and 

 more rounded at the sides ; the elytra, too, are flattened on the disc, more pointed 

 behind, and have a well-defined submarginal testaceous vitta, which is covered by an 

 attenuate stripe of pallid pubescence, the suture also being clothed with similarly- 

 coloured pubescence throughout.

Hab. Mexico x (coll Janson), Cordova, Jalapa, Almolonga, Oaxaca (Edge). 



I have seen eight specimens of this species, including three of the typical form, in 

 which the thorax is rufous, with a large oval black patch on the disc, and the elytra 

 have a submarginal testaceous vitta. In the varieties the thorax is black, sometimes 

 with the base rufous on either side, and the elytral vitta} are indistinct or obsolete. 

 The elytra in all the specimens seen, irrespective of colour, have the suture and a rather 

 broad submarginal stripe cinereo-pubescent. A. notatus is longer and more parallel 

 than A. quadrivittatus, and also differs from that species, and from A. amabilis also, in 

 the shorter, more acute, and non-divergent hind angles of the thorax. In both sexes 

 the thorax is rounded at the sides and widest at the middle, it being distinctly 

 narrowed behind. A specimen from Oaxaca is figured. 



17. Agriotes amabilis. (Tab. XXIII. figg. 5 ; 6, var.)

 Hab. Mexico 1 (coll Janson, ex Laferte). 



Yar a The prothorax rufo-ferruginous, with a broad black median vitta, which is narrowed in front and 

 behind; the elytra brown or black, fusco-pubescent, with the suture, and sometimes a short streak below 

 the humeri, cinereo-pubescent. 



Hab. Mexico (coll Janson), Yolotepec and Yolos (Salle). 

 Var. 0. Fuscous or black, fusco-pubescent, the elytra with the suture very narrowly cinereo-pubescent.
