part form transverse, somewhat irregular folds not unlike the supra- 

 basal ones, which in this case are partly obliterated, and the 

 punctures along the base are very broad ; the penultimate abdominal 

 segment is only slightly broader than the one following, the deeply 

 and closely punctate metasternum is quite glabrous. 



Length 10 mm. ; width 5^ mm. 



Hob. Ovampoland. 



Atys fallax, n. spec. 



Testaceous, slightly testaceous-red on the head and prothorax; 

 antennae reddish-brown ; clypeus blunt and slightly sinuated at 

 apex, the clypeal keel is sub-transverse, and the suture triangular, 

 the frontal part is somewhat depressed, the occipital keel is fairly 

 plain and the surface is deeply and irregularly punctate ; prothorax 

 narrowed from about the median part to the apex, but nearly 

 straight from the middle to the basal angles which are sharp, the 

 outer margin is somewhat obsoletely serrulate, and the punctures 

 are not rugose and are moderately closely set even along the sides ; 

 the punctures on the elytra are indistinctly setigerous ; those on the 

 pygidium are somewhat scattered, and the second abdominal segment 

 is nearly as wide as the one preceding. The nearest approach to 

 the shape of the genital ciaspers is perhaps that of Schizonycha 

 mediocris, but in A. fallax the open space is wider and more ovate, 

 and the apices more slender, more constricted at a certain distance 

 from the tip and quite parallel. 



Female unknown. 



Length ll-J-12 mm. ; width 6-6 j- mm. 



Hab. Southern Rhodesia (Salisbury). 



Atys hypocrita, n. spec. 



Closely allied in general appearance and colour to A. fallax ; the 

 clypeus is also blunt and slightly sinuate in front, but the clypeal 

 keel is very plainly triangular, and the frontal suture quite straight, 

 the occipital is very sharply carinate and slightly triangular in the 

 centre in the male only, the frontal suture is hardly distinct in the 

 female the antennal club of which is plainly 10-jointed ; the 

 prothorax is more narrowed from the post-median ampliated part 

 to the sharp basal angle, and the punctation is even more remote, 

 but in both sexes the basal part is smooth and impunctate ; the 

 punctures on the elongated elytra bear a very short hair ; the 

 pygidium is very deeply and somewhat closely punctate, and the 

 second abdominal segment is very plainly wider than the preceding
