STENOTARSUS. 135 



of the species before me : — The size is about that of 8. obtusus, viz. six millimetres ; the 

 colour is rich rusty-red, almost blood-red ; the elytra each with a long but ill-defined 

 pitchy cloud, leaving the margins (widely at the base) and the suture red ; the thorax is 

 wide, much contracted in front, the margin flat and wide, a little narrowed behind, the 

 sides rather strongly but evenly rounded ; six joints at the base of the antennae are red. 



3. Stenotarsus obtusus. 



Stenotarsus obtusus, Gerst. Monogr. Endom. p. 310 \ 



Stenotarsus brevicollis, Erichs. in Schomb. Reisen in Brit. -Guiana, iii. p. 579 2 (nee Perty). 



Edb. Guatemala, Sinanja in Vera Paz {Champion) ; Panama, Bugaba (Champion). — 

 Guiana 1 2 , Cayenne. 



The identification of this species is a little uncertain : I have not seen the type. Our 

 specimen from Sinanja is slightly oblong, and has four joints at the apex of the 

 antennae black. 



4. Stenotarsus nigricans. 



Oblongo-ovatus, nigro-fuscus, nitidus, fulvo-pubeseens ; antennis rufis, artieulis quatuor ultimis nigris ; pro- 

 thoracis margine laterali deplanato et paullo elevato, postice subangustato. Long. 5|-6 millim. 



Hab. Guatemala, Teleman in Vera Paz (Champion). 



The almost uniform dark fuscous colour separates this species from any other, except 

 the Colombian 8. sericatus, Gerst., in which the antennae are wholly black. In 

 8. nigricans the antennae are dark red as far as the eighth joint; and the thorax is 

 very finely, the elytra more distinctly and deeply, punctured. In an example from 

 San Juan, which is apparently not specifically distinct, the head and thorax are rufo- 

 piceous, as well as the legs. 8. nigricans is also allied to 8. rubicundus, Gerst. ; but 

 the terminal joint of the antennae is wholly black. It is a more oblong species than 

 either 8. rubicundus or 8. sericatus. 



5. Stenotarsus pilatei. 



Stenotarsus Pilatei, Gorh. Endom. Recit. p. 53 \ 



" Oblongus, rufus, cinereo-pubescens, antennis artieulis quinque ultimis nigris, elytris confeitim irregulariter 

 punctatis diseo infuscatis." Long. 5-6| millim. 



Hab. Mexico, Yucatan x ; Beitish Honduras, Belize (Blancaneaux) ; Guatemala, 

 Panzos, Teleman, and Chacoj in Vera Paz (Champion) ; Nicaragua, Chontales (Janson). 



Specimens of an oblong, unicolorous species before me from several localities appear 

 to present no important difference from the type of 8. pilatei, with which I now 

 compare them : four joints only at the apex of the antennae are black ; the size varies 

 — the type of 8. pilatei being of the smallest dimension ; and the punctuation is strong. 

 The faint cloud on the elytra of the type is hardly a character to be depended on, but 

 is present in at least one of the Chontales and in some of the Guatemalan examples.
