Descriptuins of six new species of Elaterid^, collected hi; Mr. 

 Clarence Buckley during his second expedition to Ecuador: 

 by Edward W. Janson. 



1. Chalcolepidius Backleyi, u. sp. PI. I, fig. 4. 



C. elongatus, rufo-brunueus, scjuamulis griseis dense vei-titiis; 

 protliorace lateribus sinuatis, biinaculatu ; e ytris vakle costatis. 

 Long. 27 mm., lat, 10 mm. 



Elongate, reddish-ltroAvn, densely clothed with silvery-grey 

 scales ; prothorax with a central longitudinal denuded polished 

 space, and two small circular discoidal patches ot" reddish-brown 

 scale.;;. Head with a deep, broad, triangular impression in front; 

 antennte with the third joint short, glabrous, scarcely exceeding 

 the second in length. Prothorax conspicuously longer than 

 wide, convex, rather finely and remotely punctate ; emai-ginate 

 and Avith two prominent tubercles in front; anterior angles 

 salient and dcflexed; lateral margins nearly straight, slightly 

 sinuate before the middle ; posterior angles divergent, their 

 extreme apices inflexed and embracing the shoulders of the 

 elytra. Scutellum oblong, its basal two-thirds vertical. Elytra 

 elongate, two and one-third times the length of the prothorax, 

 at the base a trifle Avider thnn it, thence gradually narrowed 

 to the summit, rounded at the apex, sutural angle unarmed; 

 the suture slightly elevated, each elytron with four strongly 

 raised longitudinal glabrous ridges, the intermediate interstices 

 faintly indicated at tlie base only. Underside and legs thickly 

 covered Avith silvery-grey scales, a denuded central longitudinal 

 space traverses its entire length. 



Chiguinda. Two specimens. 



This remarkable and conspicuous species Avhich, in its narrow 

 form and general aspect, closely resembles Chalcolepis Luczotii, 

 should be located at the head of the genus, and thus placed in 

 ipamediate proximity to that insect,
