to the apex ; wings smokj, paler at the base ; face to^\■al■ds the 

 middle keel with two more very shallow folds which simulate keels, 

 but they are shortened above and below and are only perceptible by 

 a side light." (JlelicJiar.)

" Body yellow ; tegmina pale green ; face longer than broad, 

 narrowed towards clypeus, keeled in middle, yellow ; pronotum 

 almost straightly truncate in front, without keels ; mesonotum 

 slightly arched, without distinct keels ; tegmina more than twice as 

 long as broad, narrow, posteriorly truncately straight, angles slightly 

 rounded off, sutural part of apical margin slightly angulate at apex 

 of clavns, subapical line longly remote from apical margin, the space 

 between them more than the breadth of costal membrane ; tegmina 

 pale green, apical and sutural margins brownish ; abdomen and legs 

 yellowish, apices of spines of posterior tibiae brown." {31elichar.) 



" Length 9 millim."

Division FLATOIDESARIA. 



The principal character for the separation of this division 

 is found in the great breadth of the costal membrane to the 

 tegmina ; this is three or four times broader (sometimes more) 

 than the radial area ; the tegmina and wings when at rest are also 

 held in a more or less horizontal, or only slightly vertical, position. 

 This is one of the best-marked and most easily recognized divisions 

 of the Flatince, and is found in all the warmer regions of the 

 world. We probably know at present only a moiety of those 

 found in British India, and my collection now contains an un- 

 described species from Ceylon and another from Tenasserim, 

 both of which are in too imperfect a condition for proper diagnosis. 

 A thorough search for these insects by one who had acquired a 

 knowledge of their habits would probably result in the present 

 enumeration being at least doubled ; and this remark applies to 

 several other divisions of this subfamily. 



Synopsis of Genera. 



A. Vertex of head distinctly longer than broad. 



a. Tegmina little more than twice as long as broad ; 



about as broad as wings Atkacis, p. 450. 



B. Vertex of head as long as, or slightly longer, than 



broad, 

 a. Tegmina nearly three times as long as broad, 



distinctly narrower than wings Gaja, p. 460. 



C. Vertex of head broader than long Bochara, p. 463. 



The genus Flatoides is enumerated, but not included in this 

 synopsis for the reasons stated at p. 459.
