^EOLUS. 373 



by the very elongate, posteriorly abbreviated supra-marginal thoracic carina — in some 

 specimens extending fully three-fourths the length of the thorax ; the thorax itself is 

 more finely punctured, and the elytra are more finely punctate-striate, with the 

 markings different. The variety oc resembles JE. pulchellus in colour, but it has the 

 anterior black mark on the elytra transverse, not oblique. The insect varies greatly in 

 size. The single specimens from Almolonga and Oaxaca differ from the others in 

 having the thoracic carina not extended so far forwards ; they apparently belong to 

 the same species. An example from Bugaba is figured. 



27. Mollis nigrinus. 



jEoIus nigrinus, Cand. Monogr. Elat. ii. p. 342 \ 



Hah. Mexico, Yucatan (Pilate, in coll.Janson), Temax in North Yucatan (Gaumer). 

 — Colombia 1 , Carthagena. 



Two specimens from Yucatan, differing from others from Colombia in their smaller 

 size (6-6^ millim. in length). They have the hind angles of the thorax rufous or 

 mfo-testaceous, and some of the Colombian examples are similarly coloured. 



28. Mollis lligritulus. (Tab. XVI. figg. 22, 22 a.) 



Elongate, narrow, convex, shining, finely pubescent ; black, the hind angles of the prothorax obscure testa- 

 ceous, the antenna) clear testaceous, the legs flavous. Head moderately convex, sparsely, finely punctate ; 

 the frontal carina not prominent, subtruncate ; antennae rather slender, extending to a little beyond the 

 hind angles of the prothorax, joints 2 and 3 subequal, the two together longer than 4. Prothorax convex, 

 as long as broad, narrowed in front, the sides rounded anteriorly and sinuate behind ; the hind angles 

 greatly produced, divergent, sharply bicarinate — the supra-marginal carina extending forwards to beyond 

 the middle of the prothorax and abbreviated behind, the inner carina short and extending obliquely 

 inwards from the apex of the angle ; the surface sparsely, very finely punctate. Elytra convex, two and 

 one-third times the length of the prothorax, parallel to the middle and gradually narrowing beyond, 

 separately rounded at the apex ; finely punctate-striate ; the interstices flat, somewhat roughly punc- 

 tured, the sculpture becoming rather coarsely granulate at the base. 



Length 4, breadth 1 millim. 



llab. Panama, Volcan de Chiriqui 3000 feet (Champion). 



One specimen. Allied to 2E. nigrinus, Cand., but only half the size of that insect, 

 and also much narrower and more convex ; the thorax and elytra very finely, sparsely 

 punctate, the hind angles of the thorax divaricate. More parallel and more convex 

 than M. fumatus, the thorax more finely punctured and with more divergent hind 

 angles, the elytra more coarsely granulate at the base and separately rounded at the 

 apex. 



29. MohlS disCOideilS. (Tab. XVI. figg. 23, 23 a.) 



Elongate, rather convex, shining, finely pubescent ; ferrugineo-testaceous, the head, a spot on either side in 

 front excepted, piceous or black ; the prothorax with a broad discoidal black patch, extending almost 

 to the base and apex and narrowing behind ; the elytra with a large subquadrate patch on the disc before 

 the middle, not reaching the suture, and a very broad angulate transverse fascia at about one- third
