apex (albomaculata, G. and P. nee. Herbst. = tristis, Sch.) ; the ocular 

 canthus is horizontal and spiny at apex; the pedicel of antennae is 

 also very long, and the antennal club longer and laminate, both the 

 clypeus and head are covered with contiguous, elongated, cicatricose 

 punctures ; prothorax having a slight, median longitudinal impression 

 in the posterior part, covered with closely set but not contiguous 

 punctures bearing each a minute black setulose hair becoming more 

 bristly towards the sides ; scutellum very closely punctate and setu- 

 lose ; elytra plane, with the suture raised behind, and without any 

 traces of costules in the majority of cases, but occasionally also 

 slightly bi- or tri-costulate, faintly punctate, each puncture bearing 

 a setulose black hair ; pygidium impunctate, pectus and legs briefly 

 pubescent ; the four fore tibiae are almost glabrous underneath, but 

 the hind ones are very hirtose. 



Female : Unknown to me ; McLeay has figured the female of 

 this species under the name of I. spatulipes. It certainly closely 

 resembles that of I. rostrata ; the clypeus is much shorter and 

 quadrate, deeply incised in front. 



The three developments of the $ were taken together and at the 

 same time at Port Elizabeth (Cape Colony) ; at no great distance 

 from that locality I obtained the typical albomarginata, G. and P., in 

 which the part of the clypeus following the lateral incision is slightly 

 shorter and less attenuate towards the apex, and in which the elytra 

 have narrow white lines in the shallow striae. 



Length 15-J-20 mm. ; width 9-10 mm.

Male : Black, opaque on the upper side ; margins of prothorax 

 and elytra with a white band, clypeus not incised laterally, very 

 long, slightly ampliated laterally, truncate at about two-thirds of its 

 length, with the outer angles of the truncate part prolonged as a long, 

 horizontal spine, thence the clypeus is produced as a strongly com- 

 pressed carinate very narrow lamina expanding at apex into two 

 narrow mucronate processes somewhat in the shape of an anchor, 

 both the head and the clypeus are rugose and bear even in the 

 narrowed part of the latter long, black, setulose hairs ; the antennal 

 club, although very long, is not longer than the pedicel ; the ocular 

 canthus is as in the preceding species ; the very singular shape of 

 the clypeus varies also a little, and in the smaller development the 

 narrow compressed median process is longer in proportion, and the
