broadly laterad and in the majority of species with transverse sulci 

 deep, while the number of outer spines of the caudal tibiae, though 

 individually variable, average in some of the species less than eight. 

 All of the forms are variously brilliantly colored, but have a distinct 

 general appearance of consanguinity.^^ Until much additional 

 material is secured we feel that notes on the Mexican material of 

 these genera would not be sufficiently complete to warrant pu])lication. 



The species of Melanopli which have been correctly recorded from 

 Mexico. 



(Material of the names marked with an asterisk is in the Philadel- 

 phia collections, two asterisks indicating that the type is in these 

 collections and a dagger that the type has been at hand for examina- 

 tion during the preparation of the present paper.)

'^ The genus Philocleon stands off by itself and shows this feature least. 

 ^^ We have been unable to examine the type of M. reflexus Scudder, of which 

 meridionalis may possibly be a synonym.
