are flavescent, as are also the legs ; prothorax as long as broad, 

 sensibly narrbWed laterally near the base and with the posterior 

 angles sharp ; elytra elongato-ovate with the shoulders moderately 

 rounded, and having on each side two dorsal striae very shghtly 

 punctured and two moderately deep punctures alongside the second 

 stria, the other striae have disappeared, but the eighth one is well 

 defined. 



It differs from the preceding species in the slightly less cordiform 

 shape of the prothorax ; the elytra are much less convex, and the 

 striae are not so deep nor so deeply punctured, and the two dorsal 

 punctures alongside the second stria are not so conspicuous. Length 

 3|^-3|- mm. ; width IJ mm.

Tachys exiguus, Bohem., 

 Insect. Caffr., i., p. 230. 



Black, shining, and with an apical yellowish round dot on each 

 side of the elytra and occasionally an indistinct basal one. Closely 

 allied to the preceding species, but smaller ; the prothorax is less 

 cordiform ; the striae on the elytra are quite smooth and the punc- 

 tures alongside the second one less distinct, the colour of the elytra 

 is black, shining, but with a faint trace occasionally of a round apical 

 reddish or yellowish spot on each side, and seldom of a basal one, in 

 which case it is smaller and almost evanescent. Length 2-2J mm. ; 

 width 1^ mm.

Tachys crassescexs. 



Piceous red, very shining, and with a posterior subevanescent 

 redder round patch on each side of the elytra ; palpi, legs, and 

 antennae flavescent, the third, fourth, and fifth joints of the latter a 

 little less flavescent than the others ; head normal ; prothorax sub- 

 cordiform, but as broad as long ; elytra short, broader than the 

 prothorax, and with the humeral angles not much rounded, on each 

 side there are two dorsal striae and an eighth one well defined, the 

 second stria begins at some distance from the suture and reaches a 

 little beyond the top of the declivity, outside the second stria are two 

 very shallow punctures. 



The disposition of the striae is the same as in T. exiguus, but the 

 general facies is more massive ; the prothorax is broader and the 

 elytra are less elongato-ovate. Length 2J mm. ; width 1 mm.
