III. Descriptions of some Species OjT CassididaB 7iew to 

 science. By J. S. Baly, F.L.S. 



[Bead 4tli March, 1872.] 



The insects described in the present paper have been 

 (with only two exceptions) collected by Mr. Buckley, 

 during his recent expeditions to Ecuador ; many of the 

 species, although diflering sufficiently in structural 

 characters, and in several instances, belonging to dis- 

 tinct genera, show a remarkable similai-ity in their 

 markings and coloration, being another instance of the 

 well-known fact, that insects coming from the same 

 locality often follow, to a certain extent, a common 

 pattern in the arrangement of the colour on the surface 

 of the bodies. 



There are yet some other species collected by Mr. 

 Buckley, not here described, remaining in my collection ; 

 these I hope to make the subject of a future paper.
