head very rugose, labrum and epistoma smooth, eyes very large and 

 bulging ; prothorax roughly and closely punctured, short, twice as 

 broad as long, narrowly grooved in the centre, outer margins recurved 

 from the median part to the posterior angle ; elytra twice as broad 

 as the base of the prothorax, and one-third more than the prothorax 

 at its widest part, straight at base with the humeral angles mode- 

 rately rounded, parallel, truncate but not sinuate behind, plane, 

 striate with the striae filled with closely set punctures, intervals 

 nearly plane, the third one has the two customary punctures, and 

 the sixth stria is curving strongly outward near the humeral part. 

 Length 13 mm. ; width 5 mm. 



The general facies of A. grandis is slightly different from that of 

 the other South African species, owing to the eyes being larger and 

 the thorax broader and shorter ; the sub-humeral curve of the sixth 

 stria is also very peculiar. The shape of the ligula differs also a 

 little from that of Arsinoe ; the paraglossae are produced round the 

 lateral part of the upper edge of the ligula, but edge it round instead 

 of projecting beyond it, and bear laterally several setae ; they are so 

 closely united laterally with the ligula that one cannot be distin- 

 guished from the other; the median tooth of the mentum is also 

 sharper than in the other Arsinoe.

Bronze-black, sub-opaque, antennae and legs black, first joint of 

 the former faintly rufescent at tip ; head and prothorax quite similar 

 to those of T. bi-guttatus, Catal., p. 286; elytra also similar in shape 

 and having the two impressions on the third interval, but without 

 the silky sheen, and also without any trace of flavescent patches. 

 Length 5 mm. ; width 2-| mm. 



I believe that T. immaculatus, Boh., will prove to be identical 

 with this species, and not with T. immaculatus, Lafert. This last- 

 named species stands in regard to T. sericatus, Dej., in the same 

 position as T. unicolor does to T. bi-guttatus ; they differ only in the 

 absence of flavescent patches on the elytra. 



So far T. immaculatus, Lafert., has only been recorded in South
