3 (a). Chauliognathus faustus. (Tab. XII. fig. 14.) 
Niger ; prothorace opaco, roseo-rubido, subquadrato ; elytris ochraceo-flavis, pallidis, quam thorax duplo latio- 
ribus. Long. 17-18 millim. ¢ @. 
Mas. Segmento octavo convexo, flavo ; segmentis ventralibus precedentibus albo roseoque marginatis. 
Femina. Abdomine nigro, margine et apice flavis. 
Hab. Costa Rica (Van Patten); Panama, Volcan de Chiriqui 2000 to 4000 feet 
(Champion). ° 
An elegant and curiously-coloured species: of the species recorded in this volume, 
apparently most nearly allied to C. dimidiatus, but with the thorax not so narrow as 
usual in that species, and generally of a singular rosy-red colour and spotless. Speci- 
mens occur, and that from Costa Rica is one, which have the thorax of the same 
yellow tint as the elytra. The scutellum is black, the front edge of the metasternum 
(but not the epimera) is yellow, as are the sides and apex of the abdomen, with the 
genitalia in the male. Most of Mr. Champion’s examples were beaten from the 
withered and still attached leaves of fallen trees in the forest region. 
Chauliognathus tripartitus (p. 71). 
Chauliognathus janus (ante, p. 71). 
Among a series of C. janus collected by Mr. Champion on the Volcan de Chiriqui at an 
altitude of 2000 to 4000 feet are two with the elytra wholly black, excepting the extreme 
apex, and also two or three agreeing in every respect with C. tripartitus, Chevr. I feel it 
necessary therefore to unite them as one species, for which Chevrolat’s name has priority. 
Chauliognathus distinguendus (p. 71). 
To the Mexican locality given, add :—Huanchinango (7’ruqut). 
Three female specimens which I refer to this species do not quite agree with Mr. Water- 
house’s description, having the elytra as in C. jucundus, but with the yellow subhumeral 
plagee united by a broadish fascia. They are also allied to C. tabulatus; but it is 
impossible, from a few females alone, to form an opinion on their specific identity or 
distinction. 
Chauliognathus togatus (p. 71). 
To the Mexican localities given, add :—Ventanas (forrer). 
Var. Elytris apice nigris, femoribus basi rufis. 
Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn), Ventanas (forrer). 
11 (a). Chauliognathus profundus. 
Chauliognathus profundus, Lec. Proc. Ac. Phil. 1858, p. 71’. 
Hab. Mexico, Sonora! (Schott), Northern Sonora (Morrison).
