APIDJE. 



Head transverse, nearly as wide as the thorax; ocelH three, in a tri- 

 angle on the vertex; antenna* tiliform, 

 geniculate, flagellum thickening to- 

 wards the apex ; tongue long ; labial 

 palpi 4-jointed, basal two joints 

 elongate, the apical two minute ; 

 maxillary palpi (j-joiuted, basal joint 

 thick, about as long as the following 

 two, apical three minute, subequal ; 

 labrum not notably longer than 

 broad ; mandibles narrow, acute. 

 Thorax ovate ; legs slender, short ; 

 wings moderately broad, fore wing 

 with the radial cell constricted to- 

 wards the apex and appendiculate ; 

 two cubital cells, the 1st longer than 

 the 2ud, the 2nd narrowed towards 

 the marginal and receiving both 

 recurrent nervures. Abdomen cylin- 

 drical, of moderate size. 



Nothing is known of the nesting 

 habits of the species belonging to this 

 genus. In general appearance they 

 are Aery like the species of Prosopis, 

 but can be distiuguished at once by 

 their elongate tongues. A. cupuli- 

 fera occurs in company with P. fece, 

 Bwarming on the wet sands on the banks of streams in Tenasserim.
