" Clavns granulate, its apex sometimes subacute and closed, 

 sometimes very obtuse and broadly opeu, with two veins separated 

 througbout the entire length, or united in one near apex ; costa 

 dilated, costal membrane transversely veined ; claval suture dis- 

 tinct ; anal area of wings not reticulated ; posterior tibia) without 

 ;i mobile spur." {Stal.) 



The granulated clavus is an unfailing structural test as to the 

 position of the beautiful insects which iind a place iu this sub- 

 family. Dr. Melichar has recently {su2ira) written a monograph 

 on the Flatince, and though Homopterists must be grateful to him 

 for the referential character of his work, he has unfortunatel}' 

 surcharged his pages Mith an incorrect synonymy, which greath^ 

 detracts from their permanent value. 



In enumerating and describing the not inconsiderable number of 

 genera found in British India I have found certain characters 

 which can be used in divisional separation, and though no morpho- 

 logical value can be, or is, claimed for them, it is thought they 

 will enable those into whose hands this Look may fall, especiallv 

 residents in British India, to more readily understand the generic 

 classification. 



Division PHltOMNIAlUA . 



In this division the tegmina have their apical margins (including 

 the apical and posterior angles) more or less convexly rounded, 

 and are as broad or a little broader than the winsrs.
