intentifditite shorter than the anterior, with the trochanters small, trigonal ; 

 femora very robust, short and simple ; tibiie much dilated near the middle ; 

 tarsi with the two hasal joints niiit-h dilated and deeply hilobed, furnished witli 

 long setje ; ;} and 1 like tlie anterior. 

 postirior longer than the Lntermediate ; trochanters small, claviform ; femora 

 long and simple ; tibiae strongly dilated towards the middle, and serrated on the 

 inner side near the apex ; tarsi like the intermediate. 

 Coxa anterior oblong, elongate, prominent, and nearly contingent. 

 intermedidtr rather distant, rounded. 

 posterior large, subtriangular, very remote, extending to the episterna. 



Although the organs of the mouth in this curious genus bear a collective 

 resemblance to all the other tribes e.xcept the Saciina, I have preferred placing it 

 in the present tribe on account of its similarity to Cori/lophtis in outward form, and 

 in its smooth and highly-polished surface. The elongate and acuminate shape of 

 the anterior portion of its head and the form of the mandibles and labrum are of 

 themselves sufficient to separate Catopti/.r from any other genus, but the short 

 dilated tarsi and tlie broad compressed shape of the four posterior tibia; also form 

 very distinctive characters.
