LIX. — Descriptions of two new' Coleoptera from Mada- 

 gascar. By Charles O. Waterhouse. 



Among some Coleoptera recently received from Madagascar, 

 forwarded to the British Museum by Mrs. Toy, I find the 

 two following species, which appear to be undescribed. 



Cetoniidse. 

 Coptomia celata, n. sp. 



Flavo-viridis, nitida ; elytris flavescentibus, ad apicem maculis dua- 



bus olivaceis ; pygidio piceo, crebre transversim striolato. 

 Long. 9 lin. 



Somewhat resembles C. quadrtmaculata, Waterh., in colour, 

 but is more elliptical in form, with less-projecting shoulders 

 to the elytra. It is closely allied to C. prasina, Burm. ; but, 

 besides the difference of coloration, it differs in having the 

 pygidium more strongly striolated. The sternal process is 

 similar in form ; but the portion which is formed by the meso- 

 sternum is not much longer than its greatest width ; whereas 

 in prasina it is at least twice as long as wide; the apex is 

 rounded, shining brown. The elytra are sordid yellow, with 

 an olivaceous spot just before the apex; the six dorsal striae 

 are very deep, the second and fourth interstices being much 

 broader than the third and fifth. 



Hob. Antananarivo. 



Lamiidae. 



Rhapliidopsis pulchra, n. sp. 



Nigra, dense furfurosa ; capite thoraceque lsete fulvo-ochraceis, hoc 

 tuberculo lateral! punctisque duobus posticis nigris, elytris pallide 

 flavo-albidis nigro maculatis. 



Long;. 10 lin.
