arch appear to rest on tlie apices of the cardines, and therefore 

 the apparatus approaches more nearly in its arrangement to the 

 lora of the higlier Apidas.

 Labrum transverse ; epipharynx triangular. Scales of the 

 maxillffi dark and suboval, deeply foveated, set with a few bristly 

 hairs : sclerites of the hypopharynx \'isible ou each side of the 

 labrum. Maxillary palpi 6-jointed ; blades of the maxillae rather 

 short, wide at the base, gradually narrowing into a sharply-poiuted 

 apex, their surface punctured. Paraglossse with a broad basal 

 sheath, and an apical process fringed with long hairs. Lingua 

 wide at the base, produced into a sharply-pointed apex, its sides 

 slightly concave, clothed with hairs at the base, pointing towards 

 the apex ; at the apex with some of the hairs erect, giving it some- 

 what the appearance of a bottle-brush ; each of these hairs has 

 at the apex two or three branches. Mentum beneath three times 

 as long as wide ; labial palpi 4-jointed, first joint as long as the 

 second and third together, apical joint narrower than the others, 

 longer than the third. Submentum elongate, its apex hyaline; lora 

 very strongly developed and thick. Cardines wide and straight.

Labrum transverse, slightly rounded in front, densely fringed 

 with long hairs intermixed with thicker spine-like bristles ; epi- 

 pharynx sharply angular in front. Scales at the base of the 

 maxillae curved inwards, subreniform. Maxillae with the blades 

 sinuate exteriorly, fringed with long hairs at their apex, which 

 is rounded ; internal membranous margin very narrow ; maxillary 

 palpi 6-joiuted. Paraglossae with their basal portions slightly 

 longer than wide, rounded on its external margin, somewhat 

 angular on its internal, its extreme base bearing a few bristly 

 hairs springing from deep holes ; its apical portion elongate, 

 pointed, towards the extremity clothed with bristly hairs. Lingua 

 elongate, subtriangular ; its sides slightly rounded, its apex 

 narrowly produced and clothed with long projecting hairs — its 

 base clear and hyaline, the rest finely ridged transversely and 

 set with short hairs. Mentum beneath gradually widening to 

 the apex, about 3| times as long as wide ; labial palpi 4-joiiited,
