230 SERKICORNIA. 



sinuate on each side and prolonged in an obtuse point, the surface subgranulate near the apex ; epipleuras 

 grooved their entire length and smooth ; legs ferruginous. 

 Length 9-13 millim. 



Hab. Nicaragua, Chontales (Janson, Belt). 



This species presents an extraordinary assemblage of characters and a peculiar facies. 

 It seems to be allied to F. gibbosus, but easily known from it by the form of the last 

 ventral segment. A similar structure is described in F. ventralis, but this insect has 

 flat epipleurse. 



13. Fornax adjectus. 



Cylindrical, moderately convex, narrowed behind, brown, feebly shining, finely fulvo-pubescent : antennas 

 longer than the thorax, filiform, first joint nearly as long as the next four, second distinctly longer than 

 the fourth, the latter shorter than the fifth, joints 5-10 gradually longer, eleventh one half longer than the 

 tenth ; head convex, densely punctate, subrugose, not carinate, interocnlar ridge well marked, continuous 

 in an arcuate manner across the base of the clypeus, this about half as wide at the base as the distance to 

 the eye, more or less carinate along the median line ; thorax broader at the base than long, sides arcuately 

 narrowed to the front, lateral margin single, disc convex, a very faint longitudinal impression near the base, 

 .surface very densely punctate, subopaque, but not asperate ; elytra narrowed towards the apex, nearly 

 from the base, striate, intervals closely punctate, slightly asperate near the base ; prothorax beneath 

 densely punctate, apex of the presternum very acute, antennal groove deep, broader behind, punctured 

 along its inner border, where it is not as sharply limited as usual in this genus ; abdomen very densely 

 punctured at the apex, more sparsely in front ; legs ferruginous. 



Length 7-9 millim. 



Hab. Guatemala, Capetillo, Sinanja in Vera Paz (Champion)-, Panama, Bugaba, 

 Volcan de Chiriqui (Champion). 



In many of its characters this species resembles F. lacerda, but there is no frontal 

 carina, and the antennal grooves are distinctly broader behind. The outer edge of the 

 propleural triangle is not so sharply denned as usual in the genus. Some specimens, 

 by a peculiar arrangement of the punctuation, seem to have a very short frontal carina. 

 The carination of the clypeus may be nearly entire or visible at the base only. 



14. Fornax carinifrons. 



Oblong, moderately convex, narrower posteriorly, brownish-piceous, slightly shining, sparsely, finely fulvo- 

 pubescent : antennas longer than the thorax, slender, ferruginous, first joint darker, second much longer 

 than the fourth, which is short, but little longer than wide, outer joints gradually longer ; head convex, 

 densely, subrugosely punctate, with a well-defined carina beginning at the vertex, but not reaching the 

 base of the clypeus, interocular carina interrupted, but extending slightly on the base of the clypeus, this 

 narrower at the base than half the distance to the eyes ; thorax wider at the base than long, sides 

 parallel for a short distance, then arcuately narrowed to the apex, lateral margin distinctly double in front, 

 disc regularly convex, surface densely punctate, slightly rugose at the sides, median line not impressed nor 

 carinate ; elytra striate, moderately closely punctate, rugose and transversely wrinkled at the base only ; 

 presternum finely, not densely punctate, the apical prolongation impressed between the coxas, arcuately 

 narrowed to the apex ; antennal groove not sharply limited on the inner side ; abdomen closely finely 

 punctate, fulvo-pubescent, the last segment slightly elevated at the middle of the apex and acute ; claws 

 slightly broader at the base, but not toothed. 



Length 6-9 millim. 



Hab. Mexico, Jalapa(^ci^) ; Guatemala, Pan zos and Teleman in Vera Paz (Champion).
