372 SEKRICORNIA. 



punctured, with a short smooth carina on the vertex, the frontal carina rounded and not prominent : 

 antennae reaching the hind angles of the prothorax, joint 3 slightly longer than 2, the two together as 

 long as 4. Prothorax a little longer than broad, narrowed in front, the sides rounded anteriorly and 

 parallel behind ; the hind angles strongly produced, acute, parallel, sharply earinate above, and with a 

 short oblique carina extending from the tip inwards, the supra-marginal carina extending forwards to 

 the middle of the prothorax and slightly abbreviated behind ; the surface coarsely, thickly punctate. 

 Elytra twice the length of the prothorax, narrowing from the middle, conjointly rounded at the apex ; 

 deeply and coarsely punctate-striate, the interstices convex and sparsely punctured. 

 Length 6|, breadth 2 millim. 



Hab. Guatemala, Paraiso (Champion). 



One specimen, from the vicinity of the Pacific coast. Allied to JE. pitlchellus, CancL; 

 but differing from it in the coarser punctuation of the head and thorax, the latter 

 parallel behind, immaculate at the sides, and with a much longer and sharper carina, 

 which is abbreviated posteriorly, the elytra black at the tip. The median vitta on the 

 thorax does not reach the apex, and is narrowed in front and behind. The head is 

 deep black. 



26. JEolus vermiculatus. (Tab. XVI. figg. 21, 21 a.) 



Elongate, rather convex, shining, finely pubescent ; testaceous or ferrugineo-testaceous, the head usually 

 infuscate along the middle ; the prothorax with a broad median vitta, narrowing behind, and an abbre- 

 viated marginal stripe, sometimes connected, black or piceous ; the scutellum usually infuscate or black ; 

 the elytra with two broad angulated transverse fascise — one before the middle, extending narrowly 

 along the suture to the base, and the other towards the apex, extending a short distance along the 

 suture behind — black or piceous ; the legs and antennas navo-testaceous ; the under surface partly 

 infuscate or entirely ferrugineo-testaceous. Head convex, thickly, coarsely punctate, with a short 

 smooth carina on the vertex ; the frontal carina somewhat rounded and moderately prominent; antennas 

 with joints 2 and 3 short, equal in length. Prothorax longer than broad, a little narrowed in front, 

 the sides feebly rounded anteriorly and slightly sinuate or almost straight behind : the hind angles 

 strongly, acutely produced, parallel or slightly divergent, sharply earinate at the sides above, the carina 

 extending forwards for fully one-half — in some specimens three-fourths — the length of the prothorax, 

 slightly abbreviated behind, and there connected with a short fine oblique ridge ; the surface some- 

 what thickly, finely punctate, in some specimens obsoletely canaliculate down the middle behind. Elytra 

 rather more than twice the length of the prothorax, rapidly narrowing from about the middle, rounded at 

 the apex ; finely and sharply punctate-striate, the interstices feebly convex and somewhat roughly punc- 

 tured. Beneath sparsely punctured, the punctures on the propleurse and on the sides of the metasternum 

 much coarser than on the other parts ; the prosternum almost smooth ; the apical half of the fifth ventral 

 segment densely, minutely punctate, the punctures here and there longitudinally confluent. 



Yar. a. The anterior elytral fascia divided at the suture. 



Yar. (3. The head black, the prothorax black, with the angles testaceous, the elytral fasciae very broad. 



Length 4-7, breadth 1-1 § millim. ( d $ •) 



Hab. Mexico, Almolonga, Oaxaca (Edge), Teapa in Tabasco (_£T. H. Smith) ; British 

 Honduras, Belize (Blancaneaux) ; Guatemala, Teleman, Senahu, San Juan, and 

 Chiacam in Vera Paz, Zapote [Champion); Costa Rica (Pittier, in Mus. Brit.); 

 Panama, Bugaba, Volcan de Chiriqui (Champion). 



Found in abundance by myself at various localities. The varieties described repre- 

 sent the extreme forms. Allied to 2E. pulchellus, Cand., but easily separable from it
