228 SEKKICOKNIA. 



5. Fornax aflinis. 



Fornax affinis, de Bonv. Mon. p. 386, t. 19. fig. V. 



Hab. Mexico, Orizaba *, Toxpam \ Cordova l (Salle) ; Guatemala, Coatepeque, Cerro 

 Zunil, San Isidro (Champion) ; Panama, Bugaba, Volcan de Chiriqui (Champion). 



Variable in size (8-17 millim.) and somewhat in colour. The typical specimens 

 from the Salle collection are paler than others more recently collected, probably from 

 their age. 



6. Fornax confusus. 



Fornax confusus, de Bonv. Mon. p. 383, t. 18. fig. 8\ 

 Hah. Mexico l . 



Very closely related to F. petiti, but has not been identified in our series. 



7. Fornax petiti. 



Fornax Petitii, Guerin, Ann. Soc. Ent. Fr. 1843, p. 183 a ; de Bonv. Mon. p. 382 2 . 

 Hab. Mexico : 2 . 



Has not been identified by me. 



8. Fornax castaneipennis. 



Oblong, moderately convex, hind angles of the thorax and elytra castaneous, surface moderately shining, sparsely 

 clothed with fulvous pubescence : antennae slender, longer than the thorax, pale ferruginous, first joint 

 darker, second small, half as long as the fourth, which is slightly longer than the fifth ; head convex, 

 coarsely and moderately closely punctate, interocular carina not extending on the base of the clypeus, this 

 broad at the base, slightly wider than the distance to the eye ; thorax broader at the base than long, sides 

 arcuately narrowing to the front, lateral margin distinctly doubled, disc regularly convex, a slight depres- 

 sion each side of the middle of the base, these united by a transverse impression, punctuation moderately 

 coarse, but not rugose, along the sides, much finer in front and along the middle, especially near the base ; 

 elytra parallel at the basal third, then narrowed to the apex, finely striate, intervals slightly convex, 

 moderately closely punctate, slightly transversely wrinkled at the base ; prosternum moderately coarsely 

 and closely punctate, shining, the apex acutely triangular, scarcely impressed at its base : abdomen more 

 closely punctate, fulvo-pubescent ; legs ferruginous. 



Length 7 millim. 



Hab. Panama, Volcan de Chiriqui (Champion). 



The unique example before me has the last ventral segment quite coarsely punctate at 

 the apex, and near the base a very deep fovea as if made by the perforation of a pin 

 0-2 millim. in thickness. While this species is apparently related to F. petiti and 

 F. confusus, it differs from both by the fine and sparse punctuation of the middle 

 of the thorax. As the specimen is a female, the ventral fovea may be a sexual 

 character.
