pronotum ; tegmiua narrowly opaque and punctate at base ; lateral 

 pronotal processes as seen in front apparently nnich narrower and 

 less recurved.

Melichar adds one of the following species, L. leucaspis. Walk., as 

 a synonym of this species, but he places terminalis Walk. = vicaritis, 

 Walk, in the genus Centrotus ; he had, however, probably not seen 

 these forms. Walker himself (List Hom. Suppl. p. 158) admitted 

 that his terminalis was a variet}^ of taurus. 



Bucktou gives to the speciuien he identified as L. fjazella the 

 habitat Ceylon, but I cannot corroborate it.

Closely allied to L. taurus, Fabr., but smaller ; posterior 

 pronotal process less arched at base and more obliquely straight, 

 the lateral transverse posterior processes less prominently recurved 

 and their apices less acute. These characters appear to be 

 constant, and I have seen a very long series of specimens from 

 Ceylon.

The unique type of Walker's fiexicorae is in a mutilated 

 condition, but I have no doubt as to its identity. 



" Frequents and breeds upon a thorny Capparis. Its larvae 

 mimic the thorns most effectively, as do also the adult insects.
