Mr. C. O. Waterhouse on Madagascar Cetoniida?. 79 



fourth stride pitchy yellow, pale greenish yellow, or tinted 

 with lilac. Body below green, the abdomen frequently blue. 

 Pygidiura evenly convex, not very thickly punctured. Ster- 

 nal process almost none. The anterior tibia? have three 

 sharp teeth in the female, and two, with an indication of a 

 third, in the male. 



Pantolia rufobasalis. 



Nigra, nitida, laevis ; elytris basi rufa vel rufo-flava, regione scutel- 



lari nigra. 3 $ . 

 Long. 5^-7 lin. 



Almost identical in form and colour with P. scapha, but is 

 at once distinguished by the absence of the lines of strong 

 punctures on the elytra, which are only represented by a few 

 punctures in a slight transverse impression a little behind the 

 middle. The clypeus is delicately punctured in the middle ; 

 and the lateral longitudinal impressions are not strigose as in 

 scapha. The apex of the elytra is almost destitute of punc- 

 tures ; the pygidium is finely and densely strigose. The tibia? 

 and tarsi are sometimes pitchy. 



Variety. — Thorax and elytra brownish red, with the dis- 

 coidal impressions of the elytra and the scutellar region black. 

 Pygidium pale brownish red. 



Pantolia polita, Waterh. 



I described this species from a single example. We have 

 now received several specimens of both sexes. Some of the 

 examples measure as much as 8i lines in length. Among 

 them were two or three examples which, instead of being en- 

 tirely black above, have the sides of the thorax broadly 

 margined with pitchy red; the margins of the elytra and a 

 fascia across the middle (slightly interrupted at the suture) 

 are also bright pitchy red. The tibia? are pitchy. Some of 

 the smaller specimens have the lines of punctures on the 

 elytra more extended, especially towards the shoulders and 

 along the suture towards the apex ; these specimens have the 

 clypeus more punctured, and the thorax is sparingly and ex- 

 cessively finely punctured instead of being smooth : three of 

 these smaller examples have the sides of the thorax and the 

 entire elytra obscure pitchy. 



Coptomia elegans. 



Viridis, nitidissima ; elytris flavis, striis octo imprcssis, linea sub- 

 marginali, sutura ad apiccm guttisque duabus post medium viri- 

 dibus ; pygidio parce punctate 2 .
