six-jointed ; the labial palpi four-jointed. Thorax ovate, the wings 

 having two submarginal cells. Abdomen sub-ovate. The males have 

 the face always either entirely white or yellow, or spotted with those 

 colours. 



Sp. 1. Hyl^us variegatus. 

 Prosopis variegata, Fab., Jurine. Prosopis colorata, Panz. 



Female. — (Length 2 — 3 lines). Black; a cream-coloured line 

 along the inner orbits of the eyes, reaching nearly to the vertex ; also 

 a spot or line of the same colour on the apical margin of the clypeus ; 

 the antennae rufous beneath ; the scape, and one or two following 

 joints, black. Thorax rather deeply and closely punctured ; the col- 

 lar, the tegulae in front, the tubercles, and a spot on each side of the 

 scutellum at its base, cream-coloured ; all the tibiae at their base, the 

 anterior pair in front, and the femora at their extreme apex, cream- 

 coloured ; the apical joints of the tarsi ferruginous. Abdomen, the 

 two basal segments ferruginous, and the margins of the rest rufo-pi- 

 ceous; sometimes only the base of the second segment ferruginous. 



Male. — (Length 2 — 3 lines). Black ; the face and base of the 

 mandibles, and also the scape in front, white ; the basal segment of 

 the abdomen red ; all the tibiae and basal joints of the tarsi white.

 I have also a single specimen, which I purchased of the late Mr.

 list. I suspect it is an extremely local, and perhaps not an abundant 

 species in this country. 



Sp. 2. Hyi^eus annulatus. 

 Melitia annulata, Kirby. Apis annulata, Linn. Prosopis annulata. 



Fab. Syst. Piezat. 



Female. — (Length 2j — 3 lines). Black; head closely and finely 

 punctured ; the face has an oblong angulated yellow macula on the 

 inner orbits of the eyes, below the base of the antennae. Thorax 

 closely and finely punctured ; a spot on the tegulap in front, the tuber- 

 cles, and sometimes the collar laterally, pale yellow ; the wings sub-
