The blotch commences, in both sexes, near the base of the femur, 

 extends through the ungual groove nearly to the middle of the joint, and 

 is there succeeded by a marginal row of black points in contact with the 

 bases of alternate spines.

3. CnOEEADODIS SERTILLEI, n. sp. 



? . Closely allied to the preceding, from which it differs in having 

 the marginal field of the tegmina proportionately narrower, and in the smaller 

 size, as well as in the different shape, of the femoral blotch, which is 

 small and oval, commences just beyond the ungual groove, and is follow- 

 ed by a marginal row of small black points.

In the females of the next two species, and in all probability in those 

 of Gh. rlioiiboidea also, the posterior angles of the pronotal lamella are 

 rounded-angulate and produced backwards so that the hinder end of the 

 primitive pronotum projects in the bottom of an angular emargination.

The blotch is situated, in both sexes, just beyond the ungual groove, 

 is oblong-rhomboidal in shape, and is followed by two black points on the 

 bases of alternate spines ; there is a fuscous speck at the end of the stig- 

 matal spot of the tegmina ; and the antero-lateral margins of the pronotal 

 lamellae are arcuate or convex, especially in the female.

5. Choebadodis stalii, n. sp. 



Differs from the preceding in the shape of the blotch (which is 

 pointed at both ends and commences in the ungual groove, and on either 

 side of which the femur is pale luteous-yellow instead of being clouded with
