,'„,.. a.— Smaller in size, the opercula reacliing the apex of the abdomen.

Var. b.-Opercula not reaching the apex of abdomen, but with their apices much less angularly 



produced.

As previously stated {antra, p. 52), Stal erroneously placed this species as a synonym of 

 C flavida Guer. Walker, however, had previously created the greatest confusion in the 

 identification of his own species, having firstly identified it as the C. ohteda, Fabr.,-a species 

 to which it has no similarity,-and subsequently described another specimen as a new species 

 under the name of saturata, which is necessarily adopted here. _ 



This is a most variable species, not only as regards the tinting of the tegmina, which are 

 usually clear and not shaded on the basal half, but, what is much more unusual, and even 

 unique in the genus,-as far as the knowledge of the writer at present extends,-the opercula 

 varvinc. in length and in the amount of the angular attenuation of their apices. The species 

 however, cannot easily be mistaken, as beyond the variations just enumerated, the general 

 characters are of the most uniform and consistent nature.* 



aaa. Opoxida not constricted at base, their apices obtusely angulated. 

 d. Ti'(imina unspotted. '' 9^

 remarkably from that species by the size and shape of the opercula, which have then- apices somewhat 

 acutely pointed and reaching the penultimate abdominal segment, their lateral mai-gins bemg concave 

 near base, convex about centre, and somewhat profoundly concave towards the apices; their colour is also 

 pale olivaceous-green.
