COSMEMA CITEEO-GUTTATA, Chaud., 



Catal., p. 85. 

 I have received from Escourt and the Tugela Eiver (Natal) several 

 examples of this species, in both sexes of which the humeral broad 

 yellow patch is reduced to a mere dot, but similar in other respects 

 to De Chaudoir's types. 



CoSMEMA ELEGANTULA, Bohem., 



Catal., p. 87. 



Having received lately several examples of C. elegantula, and from 

 the same locality where the original types were first captured, I find 

 that the humeral spot is missing in the female, and occasionally very 

 small in the male. My C. hreviijennis proves to be a female of ele- 

 gantula without any humeral white spot, and C. intermedia of Horn, 

 identical with my C. hrevipennis ; of this I have no doubt. Dr. Horn 

 has sent me his type for comparison, and the synonymy of this 

 species is thus :

 G. intermedia, Horn, Deuts. Ent. Zeit., 1892, p. 68. 

 0. hrevipennis, P6r., Catal., p. 87. 



CoSMEMA COARCTATA, Dej., 



Catal., p. 91. 



In the example which I compared to Dejean's type, and which 

 was absolutely similar, according to my notes, the , lateral yellowish 

 band of the elytra was not interrupted and emitted a short spur 

 directed inwardly at about two-thirds of the length, but I have seen 

 since several examples in which this band is interrupted, agreeing in 

 this respect with the original figure (Iconogr. Coleop. d'Europe, pi. 

 i., fig. 5), and the inner spur is longer and more curved, whether 

 the band is interrupted or not. 



C. coarctata is closely allied to C. vittata, Dej., and differs from 

 it merely by the lateral band, which is narrower and reaches nearer 

 to the margin than in C. coarctata, but it is as closely allied to C. 

 hamata, which is, however, smaller, the elytra are more ovate, and 

 the lateral band, which is also uninterrupted occasionally, is much 

 narrower than in C. coarctata.
