1896.] of the Goleoiitera of South Africa. 595 



Tachys peecarius. 



Light testaceous, hardly iridescent ; head a little darker than the 

 rest of the body ; palpi, antennae, and legs fiavescent ; shape of 

 palpi and head similar to that of T. crassiusculus ; prothorax broader 

 than long, ampliate laterally in the middle, and deeply sinuate 

 behind with the outer angle sharp, base and apex nearly equally 

 wide, disk smooth or nearly so ; elytra oblong, convex, with the 

 humeral angle gradually rounded, and having on each side six striae 

 reaching the posterior declivity with the exception of the sutural one, 

 but the sixth is almost obliterated, the seventh is absent, and there 

 is only a faint apical trace of the eighth left, but it is replaced by two 

 punctures, a basal and a post-median one ; the median and posterior 

 punctures on the third interval are distinct ; the posterior declivity 

 of the elytra is fiavescent. Length 3 mm. ; width IJ mm. 



Hah. Bechuanaland (Eamoutsa). 



Tachys caffer. 



Shape, size, and sculpturing of T. precarius, but the colour is 

 ferruginous red and subiridescent ; the elytra have four dorsal striae 

 only instead of six, and the eighth stria is obliterated in the same 

 manner. Length 3-3J mm. ; width IJ mm. 



Hah. Cape Colony (Grahamstown, King William's Towii). 



Tachys migrator, Fauv., 

 Eev. d'Entom. 



Brick-red, very iridescent; head black; elytra with a broad, 

 median transverse black band ; palpi and legs fiavescent ; the three 

 basal joints of antennae and the two apical ones are also fiavescent, 

 the intermediate slightly infuscate ; the palpi, head, and prothorax 

 are similar in shape to those of T. caffer ; the elytra are straighter at 

 the base owing to the humeral angle being but slightly rounded, and 

 have six dorsal striae on each side ; the striae are punctured with the 

 exception of the sixth which is not very well defined ; the two adjoining 

 the sutural one reach further back than the other three, which are 

 not produced beyond the apical margin of the transverse black band, 

 the seventh is wanting, and the eighth is as in the two preceding 

 species. Length 2|- mm. ; width 1 mm. 



Hah. Cape Colony (Cape Town). 



Tachys capicola. 

 Black, shining ; the three basal joints of antennae and the legs are 

 fiavescent, the other joints of the antennae black ; penultimate joint 

 of palpi subpyriform ; prothorax ampliated laterally in the middle,
