360 SEEMCOKNIA. 



1. iEolus bimucronatus. (Tab. XV. figg. 23, 23 a.) 



Elongate, moderately convex, subopaque, very finely pubescent; flavo-rufous or ferrugineo-testaceous, the 

 head, except in front, more or less infuscate, the hind angles of the prothorax flavo-testaceous ; the elytra 

 with the basal third or fourth, and a broad transverse fascia beyond the middle, narrowly divided at the 

 suture, black or pitchy-black ; the scutellum, under surface, and antennae ferruginous, the legs flavo- 

 testaceous. Head convex, closely, very finely punctate, the frontal carina rounded and rather prominent ; 

 antennae with joint 3 nearly twice as long as 2, the two together slightly longer than 4. Prothorax as 

 long as broad, narrowed in front, the sides parallel behind and feebly rounded from the middle forwards ; 

 the hind angles broadly, triangularly produced, acute, finely carinate at the sides above, the carina 

 extending forwards to about the middle of the prothorax and connected at the apex of the angle 

 with a short faint oblique ridge ; the surface dull, closely, minutely punctate. Elytra twice the length 

 of the prothorax, and narrower than it, narrowing from the base, the apices truncate, each finely 

 mucronate at the sutural and outer angles ; deeply and rather finely punctate-striate, the interstices feebly 

 convex and somewhat roughly punctured. 



Length 6|-8|, breadth (of the prothorax) lf-2-L millim. ( d 1 2 •) 



Hob. Panama, Bugaba, Caldera, Volcan de Chiriqui (Champion). 



Seven examples. Allied to M. platynotus, Cand., from the Amazons; but 

 differing from it in the longer apical joint of the tarsi, and in its narrower, immaculate 

 thorax, with the carina of the hind angles longer and nearly parallel with the margin 

 in front. The thoracic carina varies a little in length. In one specimen the black 

 on the base of the elytra extends a little downwards along the suture and at the sides. 

 The post-median fascia varies in width, but it is more or less divided at the suture. 

 Dr. Candeze informs me that the insect is quite distinct from his jE. steinheili, from 

 Colombia. 



2. .ffiolus nigromaculatus. 



Elater nigromaculatus, Drap. Ann. Gen. Sci. Phys. iii. p. 271, t. 42. fig. 2 (1820) \ 

 JEolus nigromaculatus, Cand. Monogr. Elat. ii. p. 301, t. 5. fig. 15 2 . 



Hab. Nicaeagua, Chon tales (fi.'M. Janson); Panama, Chiriqui (Bible), Bugaba, 

 Caldera, and David in Chiriqui (Champion). — Colombia 2 ; Guiana 1 2 ; Amazons ; 

 Antilles, Grenada I., Mustique I. 



This widely distributed species varies greatly in size, the Chiriqui specimens varying 

 from 6-9 J millim. in length. It varies very little in coloration. The punctuation of 

 the thorax is coarse. The very long thoracic carina distinguishes it from 2E. pulchellus, 

 apart from the difference in coloration. The insect has recently been found in plenty 

 by Mr. H. H. Smith in the Island of Grenada. 



3. iEoluS facetUS. (Tab. XVI. figg. 1, 1 «, var.) 

 Molus facetus, Cand. Monogr. Elat. ii. p. 318, t. 5. fig. 33 \ 



Var. a. The discoidal patch or vitta on the prothorax greatly dilated, and divided down the middle ; the 

 elytra (as in the type) with a broad subtriangular patch at the base, extending to the humeri, a broad 

 post-median fascia, and the suture narrowly, black.
