108 Mr. P. Cameron on New S'pecies 



yellow central line on the metanotum, an apical mark slightly 

 thicker than it, curved at the base and not reaching to the edges, 

 the ajjices of the abdominal segments narrowly and the ventral 

 surface, yellow. The four front legs pallid fulvous, their coxsb pallid 

 yellow ; the hinder coxa? black, broadly white at the base above, the 

 trochanters black, the femora dark rufous, tibiae yellow with a 

 fulvous tint, the extreme base and the apex more broadly black, the 

 tarsi pallid yellow, their base narrowly and the apex of the last 

 joint with the claws, black ; the metatarsus is shorter than the 2nd 

 and 3rd joints united. Wings iridescent, hyaline, the stigma and 

 nervures black. ^ . 



Length 14 mm. 



Antennas longer than the body, thickly covered with short black 

 hair ; beyond the middle is a broad white band. Face strongly 

 punctured, the clypeus smooth, roundly convex, its apex black, 

 oblique. Front bearing stout, irregular, slightly oblique keels and 

 with a stout one in the middle. Thorax sparsely covered with long 

 fuscous hair ; smooth, except for a depressed, irregularly stoutly 

 reticulated space at the apex of the middle lobe. Scutellums smooth 

 and sj)arsely haired. The base of the metanotum smooth, the rest 

 of it with stout, transverse, clearly separated stria?. Propleura? 

 stoutly striated except at the base ; the meso- similarly striated 

 except in the middle behind ; the meta- stoutly striated, the stria? 

 at the base intermixed with deep punctures ; the strias are mostly 

 curved. The central furrow on the mesosternum deep, crenulated. 

 Abdomen narrow, smooth and shining. 



This is the largest of the known Indian species. It 

 may be known from F. frontella by the darker-coloured 

 legs, by the weaker more widely separated, strise on the 

 front and vertex, by the hair on the thorax being denser 

 and longer and by the metatarsus being shorter compared 

 with the 2nd joint. F. curvicarinata may be known from 

 it by the curved keels on the front, by the smaller areolet 

 and by the yellow mark on the metanotum being widely 

 dilated at the apex. 



Friona frontella, sp. nov. 



Black ; the face, clypeus, mandibles, palpi, the inner orbits and 

 the outer above and below, the edge of the pronotum, tegulse, scutel- 

 lums, a narrow line down the middle of the metanotum from the 

 transverse keel to the base of the oblique apex, which is surrounded 

 by a broader band of similar colour and the apices of all the abdo- 

 minal segments, the yellow on the penultimate extending broadly
