projections at the base and jointly rounded at the apex, with 

 rows of prominent tubercles on the disk ; along the suture 

 a row of five or six very small ones, a large conical one at 

 the top of the declivity (uniting at its base with its fellow 

 on the other elytron), and two small ones on the declivity ; 

 the next row with six or seven tubercles, ceasing before the 

 declivity, the basal three small, the others large and conical ; 

 the third row with nine or ten tubercles, all large and 

 conical, especially the basal one ; the fourth with a very 

 large composite humeral tubercle, a medium-sized one just 

 behind, followed by three or four very small ones; finally, 

 a prominence between the humeral tubercle and the lateral 

 margin ; all these tubercles clothed with erect matted 

 scales ; between the rows there are very shallow irregular 

 paired rows of large quadrate reticulate fovea? ; the inflexed 

 sides with three complete rows of similar foveas and an 

 incomplete external row. Legs densely squamose ; the 

 femora with scattered larger fluted scales, and with sparse 

 long setae on the lower surface only ; the tibiae with long 

 suberect setae above and below. 



Length 6-8 mm., breadth 3-4 mm. 



Cape Province : Cape Flats (type) ; Stellenbosch (Dr. L. 



Peringuey). 



Described from four specimens. 



This aberrant species may be readily distinguished from 



all the previously described South African forms by the 



very remarkable structure of the prothorax and the 



numerous conical tubercles on the elytra. 



The surface of the body appears to be capable of exuding 



a glutinous substance which causes small pebbles to adhere 



to it. 



Subfamily Eeirbhijvjnjs. 



Bagons fragosus, sp. n. 



Colour black, with dense earth-brown scaling, sometimes 

 with indefinite darker patches. 



Head regularly convex, the forehead scarcely flattened, 

 and with a shalloAV central impression that is more or less 

 filled in with the scaly indumentum. Rostrum shorter thai 

 the prothorax, moderately curved, shallowly and reticu- 

 lately punctate, and without any longitudinal furrows or 

 impressions, the lower margin of the side forming a sharp 

 edge. Antenna inserted at the middle of the rostrum. 

 Prothorax as long as broad, very deeply constricted and
