separated by intervals filled with two series of elongate, linear 

 tubercles ; the alternate rows consist of small, closely set tubercles, 

 the other rows are formed by stouter tubercles, which arc much more 

 raised, each bearing a short fascicle of flavescent hairs and set at 

 some distance from one another ; prosternum sharply aculeate ; 

 anterior tibiae strongly sinuate at tip and with the second tooth 

 sharp, the basal tooth is sul)-median and sharp, and above it are 

 two sharp teeth and a strong serration near the elbow ; the 

 intermediate and posterior- tibite have numerous sharp teeth out- 

 wardly. 



This species is very numerous in the south-western part of the 

 Cape Colony. It does not seem to extend far eastward. Kolbe 

 records it from N'Goro and Victoria Nyanza, but it seems to me 

 that it is T. sulcatus and not T. luridus which has this extended 

 range. 



Length 12-15 mm. ; width 7-7i mm.

Shape and sculpture of the preceding species, and differs from it 

 merely in the rows of tubercles on the elytra being more costate, and 

 bearing usually longer and thicker pencils of hairs, these tubercles 

 are also more closely set, while those in the intermediate rows are 

 not as closely set as in T. luridus, and the interrupted bi-seriate raised 

 lines in the intervals are less deeply interrupted ; the anterior tibiae 

 are a little less sharply serrate. On examining plate xxxix. 

 it will be seen that the shape of the genital armature is slightly 

 different, the forcipate outer process is more slender and more 

 sinuate outwardly than in T. luridus, and the inner hamate process 

 is also more slender and a little more projecting ; I have noticed, 

 however, a slight variation in the length of this inner process. 



Length 12-14 mm. ; width 7-7 J mm.
