with descriptions of new species. SDL 
Sent by the Rev. Thos. Blackburn from the Sandwich 
Islands (No. 94). Mr. Blackburn tells me that the 
Species 18 rare; and that the only differences between 
what he takes to be the male and female are that the 
former has the abdomen somewhat blunter at the apex. 
~ Psilloma caudata, n. s. 
Reddish testaceous, middle of mesonotum and apical 
half of abdomen obscured slightly with fuscous ; smooth, 
shining, impunctate; prothorax and petiole with a 
fringe of white hair; sides of thorax and abdomen with 
scattered hairs. Antenne as long as the head, thorax, 
and second abdominal segment; scape as long as the 
four succeeding joints; first joint of flagellum thicker 
and a fourth shorter than the second, which is 
cylindrical and double the length of the third; the 
remaining joints to the penultimate broader than long, 
and becoming gradually thicker; last joint bluntly 
conical, and double the length of preceding. Petiole 
slightly broader than long, shorter than the coxe, and 
bulging out in the middle. Abdomen bulging out in the 
middle, sharply conical and acuminated at the apex. 
Ovipositor nearly as long as the abdomen. Wings 
shorter than the body, hyaline, ciliated; nervures 
obscure testaceous. Female. Length (exclusive of 
ovipositor) 13 lin. Expanse of wings, 14 lin. 
Sierra Nevada, Spain. Dr. Sharp. 
Forster, so far as I know, never described the type of 
his genus Psilloma; and the only described species are 
ciliata, Thoms. and incrassata, Thoms., from both of 
which the present species is very distinct. Psilloma 
forms section C of Belyta of Thomson. 
Megaspilus punctulatus, n. 8. 
Black; basal half of scape and legs with coxe reddish 
testaceous. Antenne as long as the thorax and abdo- 
men; scape longer than the three succeeding joints; 
the second joint of the flagellum a half longer than the 
first and fourth; the rest subequal, and becoming 
gradually thicker; the last as long as the two pre- 
ceding, but not thicker than them. Head pilose, 
longer than broad, somewhat broader than the thorax, 
depressed, deeply and coarsely punctured, and without
