STENOTAESTJS. 141 



almost pitchy. The scutellum is obscure in tint, almost pitchy. The elytra have the 

 apex a little recurved, and the margin there is contracted ; the punctuation is vague, 

 but distinct towards the shoulders, where a few large shallow punctures are visible. 

 This is the smallest Stenotarsus I have seen ; in general appearance it resembles a small 

 Rhymbus. A single example only. 



21. Stenotarsus exiguus. 



Breviter oblongus, piceus vel nigro-piceus ; antennis articulis quatuor ultimis nigris, artieulis secundo ad 

 octavum gradatim brevioribus; protborace transverse, disco lsevi, margine deplanato, antice latiore et 

 elevato ; elytris parcius punctatis et parce aureo-pilosis ; tibiis et femoribus posticis nigricantibus. Long. 

 3 millim. 



Hob. Beitish Hondueas, R. Hondo (Blancaneaux) ; Guatemala, San Juan and 

 Teleman in Vera Paz {Champion). 



Smaller than the Guatemalan example of S. maculicollis recorded in this work, and 

 of a very dark pitchy-black colour, excepting the portions described here as black. 

 The antennae are much thinner than in that species, and the structure of the joints 

 necessitates its being placed in a different section of the genus. The disc of the 

 thorax is not nearly so much scooped out at the side adjoining the margin as in 

 S. maculicollis ; but still the margin is well denned and raised. The punctures on the 

 elytra have a slight tendency to arrange themselves in longitudinal rows. The legs 

 are very stout for the size of the insect. 



Section B. Antennae with the third to the eighth joints not longer 

 than wide, bead-shaped.

Hob. Mexico, Cordova, Toxpam, Playa Vicente (Salle') ; Panama, Bugaba, Volcan de 

 Chiriqui (Champion). — South Ameeica, Bahia *, Santa Catarina 1 . 



Although in our specimens the pubescence is certainly coppery-red, rather than grey, 

 as stated by Gerstacker, I do not think they pertain to a different species. S. claviger 

 is easily to be recognized by the antenna? having the joints preceding the club very 

 short, the club itself as long as the rest taken together ; the first eight joints are clear 

 red ; the club is black, and its terminal joint is twice as long as the ninth or first club- 

 joint. This insect is labelled " Stenotarsus (s. g. Ephebus) antennatus" Guer. (type), in 

 Salle's collection. It is, however, not an Ephebus. 



There are three specimens from Mexico and six from Chiriqui in our collection.
