 OF THE BOMBAY PRESIDENCY.

P. Camekon. 

 (Continued from page 311 of this Volume.) 



Tetralonia ovatula, sp. nov. 



Black, the flagellum ferruginous, the basal joists black above, the pubescence 

 on the mesonotum and scutellum dark ferruginous, on the occiput, cheeks and 

 metanotum pale fulvous ; the base of the abdomen covered with white hair ; the 

 base of the 2nd segment with white pile, narrowly in the middle, widely on the 

 sides, the 3rd with a much broader band, only slightly narrowed in the middle, 

 the 4th is entirely covered with similar pubescence ; the pubescence on the apical 

 2 stiff, black ; on the ventral segments it is dark soot coloured. Wings hyaline, 

 the nervures, costa and stigma black ; the 2nd abscissa of radius longer than the 

 3rd —about one-fourth longer. The trochanters and femora are pale fuscous, the 

 4 apical joints of the hind tarsi are dark testaceous. 9 • 



Length 10 mm. 



Deesa. Angust. (Nurse.) 



A broad ovate species. Clypens punctured in the middle, the punctures clearly 

 separated, distinct ; it is almost square ; the pubescence on it and on the labrum 

 blackish. Mandibles yellowish at the base, Mesonotum and metanotum covered 

 closely with round shallow punctures. The hair on the legs is whitish, except 

 on the innerside of the hind tibiae and tarsi on which it is black. 



This does not appear to me to be the $ either of duvancellii or glabricornis ; 

 it is a broader insect than the latter, has the alar nervures black, not testaceous, 

 the 2nd abscissa of the radius is longer than the 3rd, the opposite being the case 

 with glabricornis, the clypeus is square and the apical tarsal joints much darker. 



Tetralonia glabricornis, sp. nov. 



Black, the flagellum of antennae smooth, bare, shining; bright rufous, the 

 clypeus, sides of cheeks broadly below, the lateral dilated part rounded on the 

 outerside, labrum, base of mandibles to near the middle, and tegulae yellow, the 

 pubescence on the pro and mesothorax and scutellum, rufo-fulvous (probably 

 faded) the pubescence on the sides and back of the head, pleurae and sternum 

 pale, almost white ; the pubescence on the base of abdomen pale fulvous ; there 

 is a band of white depressed pile on the base of the 2nd segment, much narrow- 

 ed in the middle, on the sides reaching to the middle of the segment, a much 

 broader band on the 3rd, not narrowed in the middle, the whole of the 4th and 

 5th covered with similar pubescence ; the pygidium black, bare, the sides of the 

 segment covered with long black pubescence. Pubescence on the legs white, on 

 the underside of the metatarsus rufous ; the apical 4 tarsal joints pale testaceous. 

 Wings hyaline, a little tinged with fulvous, the costa, stigma and nervures 

 testaceous. £ .
