or any other of its near allies. The prosternum is black and has 

 the process deeply impressed (as in the allied species) ; the meta- 

 sternum is black and shining ; and the abdomen is black, with the 

 fifth and apical segments rufous, and the three segments preceding 

 these with a yellow spot at the side of each. 

 One specimen obtained by Mr. Bonny. 



27. Cassida strigosa, n. sp. 



Elliptico-ovata, nitida ; ehjtris marginibus subexplanatis, subviri- 

 dibus, irreyulariter jjunctatis, disco concinne punctato-striatis ; 

 corpore nigra ; capite, antennis (articulis duobus ultimis prce- 

 termissis), femoruni apicibus, tibiis, tarsis, margineque toto 

 flavis. Long. 9, lat. 7 millim. 

 Not very nearly allied to any species known to me. The outline 

 is very evenly elliptical, with the whole (both thoracic and elytral) 

 margin rather widely but evenly flattened. The green colour has 

 apparently extended over the whole but faded to brown ; the suture 

 is narrowly reddish, and is hardly more distinctly marked beneath 

 than above. The striae are rather deep, with closely packed 

 punctures and convex interstices ; a row of larger punctures entirely 

 surrounds the disk, separating it from the expanded margin. 

 Two examples. 



28. Cassida fuscopunctata, n. sp. 



Breviter ovata, lutea, nitida; antennarum articulo ultimo toto, penul- 

 timo partim nigra ; elytris nitidis, disco seriatim fusco-punctatis, 

 marginibus subreticulatis,protharacis angulis externis rotundatis. 

 Lang. 6-7, lat. 5-6 millim.

I propose this name for a very plain-looking Cassida, which I 

 obtained from the collection of the late Mr. A. Murray, standing 

 as "C. pallidula, Bohem.," but the species so named by that author 

 is referred to Mexico. The same insect as Murray's is in my 

 collection from other sources named " C. pallidula." It therefore 

 appears that Boheman had suggested this name for the African 

 insect when he examined Mr. Murray's collection, but that he sub- 

 sequently described another species under that name. 



C. fuscopunctata is very shining and even, nearly as broad as 

 long ; in life it would seem to be greenish, from the tint on the disk 

 and on the thorax in the fresher examples. The reticulation of 

 the thorax and of the sides in the elytra is very distinct, and there 

 is a submarginal row of larger cell-like punctures at the edge of the 

 disk. The disk of both elytra and thorax is evenly and moderately 

 convex ; the underside and antennae except the apex are wholly 

 luteous. 



One example from Central Africa {Bonny) ; many in Murray's 

 collection from Old Calabar, now in my own collection.
