ISCHIODONTUS.— EUDACTYLIJS. 337 



- punctate ; prosternal sutures deeply excavate in front ; mesosternum declivous, the sides feebly raised ; 

 posterior coxal plates broadly triangularly widened opposite tbe point of insertion of the femora. 

 Length 7-7|, breadth 2-2| millim. ( <J $ .) 



Hab. Panama, Volcan de.Chiriqui 3000 feet {Champion). 



Many specimens. Allied to I. ichthydius, Cand., but very much smaller and less 

 elongate, the sides of the elytra from the base to a little beyond the middle broadly 

 bordered with black. The species is not known to Dr. Candeze. 



45. Ischiodontus bifasciatus. (Tab. XIV. fig. 27.) 



Moderately elongate, rather convex, shining ; rufo-testaceous, the elytra with the base somewhat broadly, and 

 a broad transverse fascia a little beyond the middle, black, the legs and antennae testaceous : above and 

 beneath somewhat thickly clothed with fulvous hairs. Head convex, not depressed in front, densely 

 punctured ; the frontal carina moderately prominent, reflexed, and strongly rounded anteriorly ; eyes 

 finely granulated ; antennae extending very little beyond the humeri, rather slender, joint 3 small, slightly 

 longer than 2. Prothorax broader than long, the sides gradually converging from the base, a little 

 rounded anteriorly ; the hind angles strongly produced, sharp, scarcely divergent, finely carinate at the 

 sides above ; the usual notches on the basal margin small and shallow ; the surface closely, very finely 

 punctate, smoother on the basal declivity, deeply canaliculate behind. Elytra comparatively short, 

 less than three times the length of the prothorax, narrowing from the base, rounded at the apex ; finely 

 punctate-striate, the interstices feebly convex at the sides, flat on the disc, and sparsely punctured. 

 Beneath thickly punctured ; prosternal sutures deeply excavate in front ; prosternal process slightly 

 declivous behind the coxae, sharply angulate before the apex ; mesosternum declivous and depressed ; 

 posterior coxal plates broadly triangularly widened towards the middle. 



Length 7§, breadth 2^ millim. 



Hab. Panama, Volcan de Chiriqui {Champion). 



One specimen. Allied to /. fasciatus and /. cruciatus, Cand., from Colombia, but 

 differing from both these species in having the thorax not so strongly transverse, the 

 suture of the elytra not infuscate between and beyond the fascia?, the elytra themselves 

 narrowing from the base, and the prosternal process sharply angulate before the apex. 



Group EUDACTYLINI. 



EUDACTYLUS. 



Eudactytus, Salle, Ann. Soc. Ent. Fr. 1854, P- 266 ', Candeze, Monogr. Elat. ii. p. 159. 



A Tropical- American genus containing eighteen described species, two of which 

 inhabit Mexico or Central America ; one from Nicaragua and one from the State of 

 Panama are now added. The large forms superficially resemble Semiotus. 



Surface shining, sparsely pubescent ; size large. 



Head and prothorax rufo-testaceous, the latter with four black spots. 



Elytra flavous, with the suture broadly, and a broad submarginal stripe, black . boucardi. 

 Elytra testaceous, with the suture and margins broadly from a little before 



the middle to the apex, black grandini.
