 t.lie tarsal spines nifous. Wings fiiscous-violaceoas, paler at 

 the base; the stigfiia and nervures black; there is an oblique 

 hyaline cloud in the l^t cubital cellule. Abdomen black; the 

 apex of the pétiole and the whole of the 2i>'l and 3'"'1 se»"- 

 meuts ferrui'inous; the l'^t setruieut is coarsely panctnred 

 except at the apex; the ventral keel is slinjhtly dilated at 

 the base; the 2i"l sej^nient, ou the basai half, is oblicpiely 

 depressed and is there closely, but not stronrvly, punctored; 

 the apex is sniooth, The middle seû^meuts ai'e friui^ed with. white

 bare; the rest covered witli long black hair; at the base of 

 the smootli part are 2 rouuded tnbercjes. 



Characteristic of this species is the incised bidentate cly- 

 peus. The inaudibles end in one, distiuctly separated, tooth. 

 The only Tndian species of JSfatilla with a bidentate clypens 

 is M. hhhm.^ Cnm. (Ann. and Mag. of Nat. Hist. July 1899) 

 but that species is smaller, the mesonotum is not furrowed, 

 the scutellum furrowed and. the last ventral segment bears 

 two keels.
