long, cordiform, smooth ; head deeply grooved laterally and having 

 a median impression at the base ; elytra ovate, convex, and with six 

 distinct, although shallow, striae on each side ; these striae reach 

 nearly to the apex, except the sixth, which reaches only as far as 

 the posterior bend of the fifth, and the third one has a moderately 

 deep puncture at about one-third of the length. Length 4J mm. ; 

 width 2 mm. 



Closely allied to T. scitulus, Catal., p. 611, which it should 

 follow. The elytra are much more ovate, there are six striae instead 

 of five on each side, and there is only one puncture on the third 

 interval instead of two ; in T. scitulus the first puncture is also 

 nearer the base than in T. tabulce.

Testaceous, shining ; head normal, antennae fiavous, the antennae 

 are not filiform, the five penultimate joints are nearly moniliform, 

 the ninth and tenth are a little longer than the preceding, and the 

 last one is a little longer and slightly broader than the tenth and 

 acuminate at tip only; prothorax broader than long, rounded 

 laterally from the apical angle to nearly the median part, and if any- 

 thing, broadest behind the apical angle, diagonal from about the 

 middle to the base, where it is not much narrowed, being about one- 

 fifth less broad than the apex, outer angles acute ; elytra truncate at 

 base and very little broader there than the prothorax at its widest 

 part, rather oblong than elongato-ovate, and having on each side five 

 striae filled with closely set and moderately deep punctures, and 

 reaching to the top of the posterior declivity ; there is also a rudi- 

 mentary series of punctures along the supra-marginal stria. Length 

 2 mm. ; width -| mm. 



The shape of the prothorax is similar to that of T. caffer, 

 Catal., p. 595, but the elytra are more oblong ; the number of 

 punctured striae is also greater, but the most distinct characteristic 

 distinction is in the shape of the antennae, which in T. caffer are fili- 

 form, with the articles elongate and the ultimate one very slender and 

 sharply acuminate, and thus very different from those of T. emeritus.
