CYLINDEODERUS— OCTINODES. 551 



four times the length of the prothorax, and much wider than it, very gradually narrowing from the hase ; 

 coarsely and deeply punctate-striate, the interstices not or very little wider than the punctures of the 

 strioe, convex (natter in some specimens), and somewhat thickly punctured. Prosternum and propleurae 

 very coarsely, the metasternum and abdomen rather finely, punctate. Legs elongate, the intermediate 

 and hind pairs with the tarsi considerably longer than the tibiae. 

 Length 6-6|, breadth l|-lf millim. 



Hah. Guatemala, El Tumbador, Las Mercedes, Cerro Zimil (Champion). 



Five specimens, all from the Pacific slope, from elevations between 2500 and 4000 

 feet. Paler and a little more elongate than C. mexicanus, with the thorax more 

 quadrate, the punctures of the elytral strise much coarser, and the tarsi relatively 

 longer. 



OCTINODES. 

 Octinodes, Candfeze, Monogr. Elat. iv. p. 487 (1863). 



The three known species of this genus are all from Tropical South America ; a 

 fourth is now added from the State of Panama. 



1. Octinodes carinatus. (Tab. xxiv. fig. 1, <s .) 



J . Elongate, rather narrow, scarcely shining ; fulvo-testaceous, the head in front, the mandibles, and scutellum 

 piceous, the elytra testaceous, the metasternum, abdomen, eyes, and antennas black, the legs piceous, with 

 the femora fusco-testaceous ; above thickly clothed with long, semierect fulvous pubescence, beneath 

 with decumbent fulvo-cinereous hairs. Head swollen on each side above the point of insertion of the 

 antennas, very coarsely, coufluently punctate, the eyes large and prominent ; antennas with the fourth 

 and following joints each furnished with a very long, slender ramus — that on the fourth and last joints 

 shorter than the others, which are excessively elongate, — the rami all thickly clothed with long fine hairs. 

 Prothorax subquadrate, slightly narrowing forwards ; the hind angles very long and strongly divergent, 

 obsoletely carinate at the tip ; the surface coarsely, closely punctate, the punctures here and there 

 confluent, obsoletely canaliculate. Scutellum closely, finely punctate, with a smooth raised line down the 

 centre. Elvtra nearly four times the length of the prothorax, and much wider than it, parallel to a little 

 beyond the middle ; coarsely punctate-striate, the interstices convex and closely punctured. Prosternum 

 and propleuras sparsely, the metasternum and abdomen closely, rather coarsely punctate, the inner part 

 of the propleurse smooth. Legs rather slender. 



Length 10, breadth 2| millim. 



Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 



One example. Closely allied to O. capillatus, Cand. (the type of which is contained 

 in the Janson collection), from Colombia and Venezuela, which is sometimes similarly 

 coloured • but differing from it in the carinate scutellum, the more slender limbs, and 

 the shorter ramus on the fourth antennal joint, as well as in its smaller size and 

 narrower shape.
