of the eyes, terminating a little above the insertion of the antennae, 

 and an ovate spot at the anterior margin of the clypens cream- 

 coloured ; the head closely punctured. Thorax with a line on the 

 collar attenuated in the middle, the tubercles, and a spot on the 

 tegulae in front cream-coloured, and the basal half of the tibia? 

 of the same colour outside ; a similar coloured spot at the extreme 

 base of the posterior tarsi ; wings hyaline and iridescent ; the 

 niesothorax and scutellum shining and closely punctured ; the 

 metathorax truncate, the enclosed semicircular space at its base 

 rugose. Abdomen shining and finely punctured, pilose towards 

 the apex, rounded at the base and gradually narrowing to the 

 apex, which is pointed. 



Hah. Makassar. 



11. Prosopis blackburni. 



Female. Length 3 lines. — Black ; and closely resembling the female 

 of P. facilis, but has the flagellum of the antennae fulvous beneath. 

 The metathorax with a few short striae at the base ; wings sub- 

 hyaline and iridescent, the recurrent nervures uniting with the 

 transverse nervures of the second submarginal cell, as in P.facilis. 

 The abdomen smooth, shining, and impunctate. 



Male. The size of the female ; the front of the head, as high as the 

 antennae, yellow, the scape with a yellow line in front, the flagellum 

 fulvous beneath. The tibiae and tarsi yellow, with a small black 

 spot on the tibiae behind, and the apical joint of the intermediate 

 and posterior tarsi fusco-ferruginous ; wings and abdomen as in 

 the female. 



Hab. Sandwich Islands, island of Maui. 



It will be seen that the male of this species differs greatly in 

 colouring from the same sex of P. facilis, although the females have 

 little specific distinction. 



12. Prosopis fuscipennis. 



Male. Leugth 4\ lines. — Black. The head and thorax semiopaque; 

 the abdomen smooth, very finely punctured, sparsely so at the 

 base, bright and shining ; wings fuscous, inclining to fulvous, and 

 brightly iridescent. The head closely and finely punctured ; the 

 clypeus somewhat produced, and truncate anteriorly ; the scape of 

 the antennae compressed, its lower margin narrowly whito. The 

 margin of the prothorax white ; the mesothorax and scutellum 

 closely punctured ; the metathorax rugose ; the anterior tibiae and 

 tips of the femora fulvous within, the four apical joints of the 

 tarsi rufo-testaceous.
