ends (sides) shortened, bounded by a sbarp ridge, except in 

 the middle line posteriorly ; this area is shining and is 

 divided into three subequal ])arts by two longitudinal carinas, 

 the lateral spaces being rather obscurely obliquely ridged. 

 Legs piceous brown and yellowish white ; femora dark except 

 the anterior knees ; tibiae light, the anterior ones Avholly so, 

 the middle ones with a dark spot behind, the hind ones with 

 a very broad, dark, subapical ring; tarsi yellowish white, 

 with the last two joints of the middle and the last three of 

 the hind tarsi pale brown ; tegulffi with a white spot in 

 front ; abdomen rather narrow, the hardly noticeable fine 

 pilosity white as far as the third segment, after that black,

Prosopis disjuncta, sp. n.

Strongly punctured, but not so closely as in -P. albonitens, 

 the punctures of the mesothorax in particular being much 

 larger, more irregular, and less dense ; dark blue, the head 

 and thorax inclining to steel-blue, the abdomen to deep rich 

 purple ; light markings cream-colour or a very pale primrose ; 

 wings hyaline, nervures dark. Clypeus light, with a dark 

 margin, this margin varying in breadth, so that the light 

 triangle may be very large or rather small ; lateral face- 

 marks broad, bow-shaped, notched above by the antennal 

 sockets ; mandibles and scape wholly dark ; flagellum 

 brown, yellowish ferruginous beneath; middle of front 

 elevated and rugose, the elevation bounded on each side by 

 a sharp ridge; at each side of this elevation is a smooth 

 shining area ; hind border of prothorax and large spot on 

 tubercles light, but the two light areas are not nearly 

 continuous; basal area of metathorax somewhat dumbbell- 

 shaped, broader at the sides than in the middle ; tegulse with 

 a small liglit spot. Legs dark, slightly metallic ; the anterior 

 tibia and metatarsus in front, a small spot at base of middle 

 and hind tibiae, a very small spot at apex of middle tibia,
