The following two species have been described by Mr. F. 
Smith in his Cat. of Hymen. Ins. pt. i., p. 23, from the 
Sandwich Islands. It is more than probable that they are 
identical with some of the species described above, but, as 
the descriptions are not very clear, and as I have not speci- 
mens of all the species for comparison, I have not been able 
to satisfy myself as to this. To make the descriptions of 
Prosopis complete I give a copy from Smith’s work of those 
of anthracina and flavipes. (P.C.) 
11. — Prosopis anthracina. 
“Female. — Length 2J lines. — Entirely black, head and 
thorax very finely punctured, the apical joints of the 
antennae testaceous beneath. Thorax, the tegulse 
testaceous, the wings hyaline, the nervures dark 
testaceous; the enclosed portion of the metathorax 
longitudinally irregularly sulcate at its base. Abdo- 
men very smooth and shining, beneath it is dark 
fusco-ferruginous, as well as the legs ; the claws 
ferruginous. 
Male. — -The clypeus and a space on each side not touching 
the eyes, forming together an oval, bright yellow; 
the scape dilated, triangular ; the flagellum testaceous 
beneath. Thorax, the anterior tibiae in front and the 
claws testaceous; otherwise as in the other sex. 
Hab. Sandwich Islands.” 
12.— Prosopis flavipes. 
“ Male. — Length 2 J lines.— Black ; the face yellow, the 
colouring is continued upwards on each side nearly 
to the vertex of the eye; the scape cylindrical, black, 
the rest of the antennae orange — yellow beneath. 
Thorax, the metathorax has no distinctly enclosed 
space and is subrugose; the wings hyaline, the 
nervures dark fuscous, all the tibiae and tarsi bright 
yellow, the former have a ferruginous stain behind. 
Abdomen smooth and shining, the margins of the 
segments narrowly rufo-testaceous, 
Hab. Sandwich Islands.”
