FOENAX. 227 



1. Fornax atripennis. (Tab. x. fig. 15.) 



Oblong, cylindrical, feebly convex, orange-yellow, antennae, elytra, abdomen, and tibiae black, clotbed with 

 pubescence the colour of the surface, feebly shining : antennae longer than the thorax, second joint very 

 small, third half as long as the first, fourth but little shorter, the following joints very slightly longer ; 

 head convex, densely punctate, front not carinate, interocular ridge not elevated, clypeus more than half 

 as wide at the base as the distance to the eye, surface fulvo-pubescent ; thorax wider at the base than long, 

 sides nearly parallel posteriorly, arcuately narrowed in front, lateral margin very indistinctly double, disc 

 convex, a slight oblique impression each side of the middle of the base, between which is a slight convexity, 

 surface very densely punctate, scarcely rugose, subopaque, fulvo-pubescent j elytra finely striate, intervals 

 flat, the entire surface closely but not roughly submuricately puncta,te ; epipleurae concave near the base 

 and smoother ; prosternum beneath very finely closely punctate, the apical process acute at the tip ; antennal 

 groove deep, smooth, sharply defined, parallel ; abdomen finely, not densely punctate ; last ventral segment 

 rounded at the tip ; femora ferruginous-yellow, tibiae usually piceous, except sometimes the anterior pair, 

 tarsi piceous, last two joints rufo-testaceous. 



Length 9-11 millim. 



Hab. Guatemala, Zapote (Champion); Panama, Bugaba (Champion). 



The number of bicoloured species is small, and from all of them this one is easily- 

 known by its arrangement of colours. 



2. Fornax notabilis. 



Fornax notabilis, de Bon v. Mon. p. 423 \ 

 Hab. Mexico \ Cordova (Salle). 



The thorax is orange-red, with the sides narrowly black, and a median black stripe 

 broader in front. The elytra are piceous-black. 



3. Fornax variipennis. 



Fornax variipennis, de Bonv. Mon. p. 421, t. 21. fig. 4 1 . 



Hab. Mexico, Teapa (coll. ChevroJat l ) ; Guatemala, Senahu in Vera Paz (Champion) ; 

 Panama, Bugaba (Champion). — Brazil 1 . 



Easily known by the coloration. The thorax has on each side of the middle a paler 

 space extending from the base to the apex, and on each elytron are two oblong-oval 

 spots of similar colour. 



4. Fornax infrequens. 



Fornax infrequens, de Bonv. Mon. p. 371, t. 18. fig. 1 . 



Fornax guadeloupensis, Fleut. & Salle, Ann. Soc. Ent. Fr. 1889, p. 405, t. 7. fig. II 2 . 



Hab. Mexico 1 ; Panama, Bugaba (Champion). — Antilles, Guadaloupe 2 . 



A large species closely related to F. affinis. It has not been certainly identified 

 in our series, although a rather small specimen (7 millim.) from Bugaba seems to 

 belong here. 



I have examined the type of F. guadeloupensis ; it does not differ from F. infrequens, 

 de Bonv.
