posteriorly, and does not quite touch the sutural vitta, while in the other specimen the 

 first of the spots placed near the lateral margin is absent. The shape of the thorax, as 

 well as its punctuation, also varies : in both specimens the thorax is slightly narrower at 

 the base than the elytra ; but in one the punctuation is less close, and a small fovea is 

 placed at each side, the thorax being at the same time less long and the anterior angles 

 more acute, which probably is attributable to sexual difference.

The only specimen which I have seen is the type in Mr. Baly's collection. I am 

 inclined to believe that the species is but an extreme variety of C. ancoralis. In the 

 present insect nearly all the elytral markings are confluent.

Guerin's type, in the collection of M. Salle, and another specimen (named by Stal), in 

 Mr. Baly's collection, which is now figured, agree well with several specimens obtained by 

 Mr. Champion. The usual spot at the shoulder is in this species short and subquadrate ; 

 and the rest of the spots are extremely small and surrounded by a pale margin, this 

 latter being also visible round the sutural design.

I have no doubt that the above two species described by Stal are in reality identical, 

 as the very numerous specimens and the type before me prove. The species is a rather 

 variable one in regard to the colour and number of the elytral spots, some specimens 

 having the latter of a rufous, others (and they are the majority) of a greenish colour. 



Stal's C. famularis is founded on a specimen in which the spots are larger and 

 more closelv placed in consequence ; but the insect does not differ sufficiently from his 

 C. argus to justify its being considered a distinct one. It is even doubtful to me whether
