SEREICOENIA (ELATERID^) 555 



the exception of the outer part of the propleurse ; the rest of the thorax is rufo- 

 testaceous, and of the elytra testaceous or flavo-testaceous. The male has much longer 

 antemiEe than the female, with the joints 4-10 broadly and acutely triangular. These 

 examples have the thorax sinuate at the sides behind, so that the long hind angles 

 appear strongly divergent, and the elytral interstices feebly convex and sparsely punc- 

 tured. The single specimen (a small male) from Costa Rica represents yet another 

 variety. It has the black median vitta on the thorax still broader and the apical patch 

 on the elytra occupying rather more than their posterior third, the suture thence to 

 the base being broadly black. The largest of the additional specimens measures 

 10 millim. in length and 2§ millim. in width. A male from the Volcan de Chiriqui is 

 now figured. 



5 (a). Anoplischiopsis trinotatus. (Tab. XXIV. fig. 9, $ .) 



Moderately elongate, rather broad, shining ; the head black or ferruginous, the prothorax fulvo-testaceous, 

 with a median vitta and an abbreviated marginal stripe black (the latter piceous in one specimen), the 

 scutellum black, the elytra fulvo-testaceous, with a large spot on the outer part of the disc a little beyond 

 the middle (not reaching the margin) and the apex black ; the antennae, legs, and under surface, tbe 

 propleurae excepted, black or piceous ; somewhat thickly clothed with long, decumbent pubescence, which 

 on the upper surface partakes of the ground-colour, that on the lower surface yellowish-cinereous. Head 

 coarsely, closely punctate, the frontal carina flexed downwards in the middle and not very prominent ; 

 antennse about reaching the hind angles of the prothorax, joint 3 a little longer than 2, the following 

 joints moderately dilated, triangular. Prothorax about as long as broad, the sides gradually and arcuately 

 converging from the basal third, sinuate behind ; the hind angles strongly produced, acute, and slightly 

 divergent, sharply carinate ; the surface finely, sparsely punctate, deeply canaliculate behind. Elytra 

 about two and four-fifths longer than the prothorax, gradually narrowing from the middle and conjointly 

 rounded at the apex ; finely punctate-striate, the interstices convex throughout and somewhat thickly 

 punctured. Beneath finely, rather sparsely punctate, the propleurse with widely scattered punctures. 



Length 8|, breadth 2| millim. ( $ .) 



Hab. Nicakagua {Salle), Chontales (Belt). 



Two examples. Closely allied to A. lineatocollis, but broader and more parallel than 

 the female of that species, with the sides of the thorax infuscate or marked with black, 

 and the elytra very differently marked, the apex and a post-median spot on the outer 

 part of the disc of each being black.
