JEOLUS. 371 



23. JEolus cruciger. (Tab. XVI. figg. 18, 18 a.) 



Molus cruciger, Steinh. Col. Hefte, xiv. p. 124 (1877) \ 



Var. The prothorax with a discoidal black patch, which is narrowed in front and behind, and marked with a 

 rufous line down the middle of the basal half ; the elytra with the base, the suture very broadly, a post- 

 median fascia, the apex, and the epipleurse, black ; the prosternum in great part black. 



Hab. Panama, Obispo (Salviri). — Colombia l . 



A single specimen from Obispo differs from JE. cruciger, Steinh., the type of which 

 has been communicated by M. Rene Oberthiir, in being more marked with black ; 

 it also has the disc of the thorax a little less closely punctured, with a smooth median 

 line. A- similar variation in colour is common to JE. melliculus and other species 

 of the genus. The long supra-marginal carina of the thorax is abbreviated behind. 



24. JSolus rugipennis. (Tab. XVI. figg. 19, 19 a.) 



Elongate, convex, shiniug, finely pubescent ; rufous, the prothorax with a faint infuscate streak about the 

 middle, the scutellum piceous ; the elytra black, with a broad transverse rufous median fascia, which is 

 widened inwards and connected along the suture and at the sides with a similarly-coloured narrow 

 apical patch ; the under surface, the epipleurse included, rufo-ferruginous ; the antennae ferruginous, 

 the legs testaceous. Head convex, coarsely, closely punctate, with a short smooth carina on the 

 vertex ; the frontal carina rounded and moderately prominent; antennae very short, not reaching the hind 

 angles of the prothorax, joint 3 slightly longer than 2, the two together about as long as 4. Prothorax 

 much longer than broad, convex, narrowed in front, the sides parallel behind and slightly rounded from 

 the middle forwards ; the hind angles strongly, acutely produced, parallel, very sharply carinate above, 

 the carina distant from the margin, extending forwards to beyond the middle of the prothorax, slightly 

 abbreviated behind, and there connected with a short, sharp, oblique ridge ; the surface thickly and 

 rather coarsely punctate throughout. Elytra twice the length of, and narrower than, the prothorax, 

 gradually narrowing from the base, the apices slightly divergent at the sutural angle ; finely but deeply 

 punctate-striate, the interstices rather convex, roughly punctured, transversely rugose and granulate 

 towards the base. Eeneath thickly, somewhat coarsely punctate, the propleurse with very coarse, 

 scattered, round punctures. 



Length 8, breadth (of prothorax) 2\ millim. 



Hab. Panama, David {Champion). 



One specimen, probably a female. This insect does not appear to be very closely 

 allied to any described form ; it belongs to Candeze's second division of the genus. 

 The elytral interstices are rugose and granulate towards the base, rougher than in any 

 of the allied forms. 2E. rugipennis is perhaps best placed near M. circumcinctus, Cand. 

 The colour is probably variable. 



25. ^olus atriceps, (Tab. XVI. figg. 20, 20 a.) ■ 



Elongate, convex, shining, finely pubescent ; ferrugineo-testaceous, the head entirely black, the prothorax with 

 a rather narrow elongate-oval black patch on the disc before the middle, the scutellum black ; the elytra 

 with a short sutural stripe in front, a broad oblique band below the base — extending inwards to the 

 second stria and outwards to the margin, and reaching the humerus, — a sharply angulated fascia towards 

 the apex, continued down the suture to the tip, and the apex itself narrowly, black ; the antennae, 

 epipleurse, and legs testaceous, the under surface entirely ferrugineo-testaceous. Head convex, coarsely
