riiunded ; the secoud is vorv small, and stands nuderneath the shoulder ; the third is

 similar in shajie to tlie third, and connected witli tlie first liasal spot ; the fifth is 

 largest, anteapical, and almost ol' the shape of the letter (_', but broader in front and 

 jjointed posteriori)-. 



Hah. Old Calabar. 



This species may be easily distinguished from other forms with a somewhat 

 similar style of marking by the antennae being very long in both sexes.

The large patcli wliich occupies nearly the wliole of the posterior hall' of the 

 elytra is nearer the midille on the .suture tluin on the sides, and is cmarginate 

 anteriorly. In one specimen the postscutellar elongate mark and the apical patch 

 are connected with each other. The two black markings near the ape.\ are variable 

 in form, and being confluent in one specimen, have almost the siiai>e of the musical 

 letter c).

Its nearest allied sjiecies is Ch. {Lamia) amoena (Dalra.j, the jjrothora.x of which 

 has also four brownish vittae. The latter species wants the small frontal spot, and 

 bears on the base of the elytra a small greenish yellow marking, not occurring in 

 Gh. quaclririltata ; the scutellnm is also dift'erent in colour, being entirely covered with 

 a sulpiuu- or ju'imrose yellow pnbescence in Ch. qiuulrwittata.
