FORNAX. 229 



9. Fornax mendax. 



Fornax mendax, de Bonv. Mon. p. 393, t. 19. fig. 7 \ 



Hab. Mexico \ Cordova (Salle) ; Guatemala, Zapote (Champion) ; Nicaragua (Salle) 

 Chontales (Belt). 



A large species resembling F. affinis, but with smooth grooved epipleurse. 



10. Fornax obrutus. 



Fornax obrutus, Guerin, Ann. Soc. Ent. Fr. 1843, p. 183 l ; de Bonv. Mon. p. 395, t. 19. fig. 8, 2 . 



Hab. Mexico, Orizaba (coll. Chevrolat x 2 ) ; Guatemala, Zapote ( Champion) ; Panama, 

 Bugaba (Champion). 



The thorax is simply punctate and not roughly sculptured, while in its other 

 characters the species is close to F. mendax. 



11. Fornax sceleratus. 



Oblong, rather narrow, subcylindrical, moderately convex, brownish, feebly shining, sparsely clothed with 

 fulvo-cinereous pubescence : antennae slender, as long as hall* the body, ferruginous, second joint very 

 small, third two-thirds as long as the first, fourth shorter, this to the eleventh gradually longer ; head 

 convex, coarsely, densely, and somewhat roughly punctured, interocular carina feebly elevated, not 

 extending on the base of the clypeus, the latter as wide as the distance to the eye ; thorax broader at the 

 base than long, sides arcuately narrowed from the base to the apex, lateral margin doubled in front, disc 

 convex, densely punctate and subopaque, the punctures simple posteriorly, but rough at the apex and sides, 

 a short smooth line at tbe middle near the base ; elytra very little narrowed at the apex, striate, intervals 

 flat, sparsely punctate, especially posteriorly, not dense at the base, and slightly asperate near the humeri 

 only ; epipleurse smooth, and grooved their entire length ; prosternum densely punctate, the apex grooved 

 between the coxae and acute at the tip ; antennal grooves broad and deep, nearly as wide as the propleural 

 triangle, not wider in front ; mesopleurae sparsely punctate over the entire surface ; abdomen sparsely 

 punctate, the last segment rough at the apex ; legs ferruginous, the first joint of the hind tarsi scarcely as 

 long as the following joints united. 



Length 6-5 millim. 



Hab. Panama, Volcan de Chiriqui (Champion). 



Closely related to F. mendax and F. obrutus, but narrower than either, and with 

 much wider antennal groove. It seems to connect Fornax with Biphytaxis.

12. Fornax truncatus. (Tab. X. fig. 16.) 



Oblong, cylindrical, very obtuse in front, piceous- brown, feebly shining, sparsely cinereo-pubescent : antennae 

 nearly twice as long as the thorax, slender, second joint very small, third about half as long as the first, 

 joints 4-6 gradually a little shorter, 7-11 gradually longer ; head moderately convex, densely coarsely 

 punctured, interocular carina scarcely elevated, broadly interrupted at the base of the clypeus, which is 

 slightly wider than the distance to the eye ; thorax subquadrate, broader than long, sides straight and 

 parallel, rounded only at the front angles, lateral margin double, the two edges sharp but very close, disc 

 very convex, surface opaque, granulate moderately closely in front, but on the basal declivity rather 

 sparsely punctate ; elytra striate, intervals comparatively finely punctate, not closely, and gradually more 

 sparsely towards the apex, humeral region slightly asperate ; prosternum not closely punctate, broadly 

 grooved between the coxae, apex acute ; antennal grooves deep, wider just at the apex ; mesopleurae in 

 great part smooth, sparsely punctate posteriorly ; abdomen sparsely finely punctate, the last segment
