SUPPLEMENT. 



Tachys castaneicolor (p. 139). 



To the localities given add : — Panama, Bugaba (Champion). 



4(b). Tachys limbatellus. 



T. corusco magis elongatus, subdepressus, fulvo-testaceus ; capite elytrorumque sutura et marginibus fuligineo- 

 fuscis ; palpis, labro et pedibus pallide testaceis, antennis plus minusve infuscatis ; thorace parum trans- 

 verso, postice sat angnstato, angulis posticis valde obtusis nullo modo prominentibus ; elytris (stria suturali 

 excepta) vage 2- vel 3-striatis (striis exterioribus curvatis). 



Long. 1| lin. 



Hdb. Panama, Bugaba (Champion). 



More elongated and parallel-sided and flatter than T. coruscus, T. monostictus, 

 T. chiriquinus, and allies, approaching in these respects T. scutellaris. The colour is 

 rather dingy pale testaceous, with the greater part of the head, the suture, and external 

 borders of the elytra sooty brown, and the dusky colour being ill-defined. The elytra 

 have an opalescent silky gloss, not so strong as in T. coruscus ; and the shallow striae, 

 two to three or four on each side of the sharp sutural striae, have an appearance as 

 though converging inwards towards the base. 



4(c). Tachys diminutus. 



Tachys diminutus, Bates, Entom. Month! . Mag. viii. p. 11 (1871) \ 



Hah. Panama, Bugaba (Champion). — South Ameeica, Amazons 1 . 



Much smaller than T. coruscus, and further distinguished by the hind angles of the 

 thorax being salient. In my original description I mentioned only one, the sutural, 

 stria as being distinct ; this does not reach the base, and there are faint indications of 



two or more other much abbreviated 

 Panama than in the Amazons exam pi 



4 (d). Tachys vorax. 



Tachys vorax, Leconte, Ann. Lyceum N. York, v. p. 194 \ 



Hah. North America, Rivers Gila and Colorado l . — Mexico, Northern Sonora (Mor- 

 rison) . 





19(a). Tachys insularum. 



T. amplicolli affinis ; paullo minor, sat convexus, rufo-testaceus ; antennis, basi pedibusque pallidioribus ; thorace 

 valde transverso, antice rotundato-ampliato, postice sat angustato, sinuato, angulis rectis; elytris ovatis 

 stria suturali basin attingenti, 2 a profunde impressa, 3 a minus distincta et multo abbreviata ; punctis 

 setiferis utrinque duobus discoidalibus, striola recurva, curta. 



Long. § lin. 



Hab. Panama, San Miguel, Pearl Islands (Champion).
