The following description of a new genus of Chalcidide found in 
the cells of Anthophora was then given :— 
Genus Antuornorasia, Newp. 
Fem. Caput thorace latius; antenne 6-articulate, pilose, articulis 2% 
3te 4to 5teque subzequalibus, 6° clavam elongato-ovalem efformante. 
Thorax abdomenque longitudine zquales. Ale vend mediana bifida. 
Tarsi 5-articulati. Mas: Antenne 4-articulate, articulo basali ar- 
cuato, magnoperé dilatate, inferné excavato, 24° cylindrico, 3° magno 
globoso, 4'° elongato-ovali, Oculi stemmatosi. _ Ale abbreviate. 
ANTHOPHORABIA RETUSA (/em.). Aineo-viridis, capite magno, oculis 
compositis nigris, abdomine nitido ovali, alis magnis rotundatis, pedibus 
flavescentibus. (Jas) flavus vel saturate ferrugineus, capite magno ro- 
tundato ocello utrinque unico tribusque in vertice instructo nigrescente, 
pedibus robustis.—Long. lin. 1. 
Mr. Newport found this species in abundance in the nests of An- 
thophora at Richborough in Kent, while searching for the larve of 
Meloé in August 1831, 1832 and 1834. The larva is apodal, sub- 
cylindrical and slightly attenuated at each extremity, and formed of 
fourteen segments, with a small head and short acute mandibles, and 
there were usually from thirty to fifty specimens in each bee-cell. In 
some instances they changed to nymphs and imagos at the end of 
summer, but in others the change did not take place until the 
spring, at which time the perfect insect comes forth. 
The author states that he was unable to find any description of 
this curious parasite in the works of entomologists; the only writer 
who makes reference to an insect which, possibly, may have some 
affinity with this, being Mr. Westwood, who refers to a species, 
found by M. Audouin in France, under the name of Melittobia Au- 
douinti, but without describing it; so that if the two insects should 
prove to be identical, which Mr. Newport considers doubtful, this 
name cannot beadopted. Reaumur and Degeer both found parasites 
in the cells of Mason-bees, but their species have not been clearly 
made out. 
The author deduced conclusions with regard to the habits of 
Anthophorabia from peculiarities in the anatomy of the sexes, and 
expressed an opinion, from the absence of an ovipositor in the female, 
from both sexes being found in activity in the closed bee-cell, and 
more especially from the male possessing only stemmata, instead of 
the usual compound eyes of winged insects, that impregnation is 
effected before the female first quits the cell, and that she deposits 
her eggs in new cells while these remain open and are being pro- 
visioned. The difference of structure and function between compound 
eyes and ocelliwas explained in support of these opinions, and thesexes 
of Anthophorabia were contrasted with those of Stylops, as described 
by the author in bis ‘‘ Memoir on Meloé,” read to the Society on the 
19th of January 1847. These differences of structure in similar or- 
gans were regarded as always indicatory of peculiarities in economy. 
A second species of Chalcidide had also been found by the author, 
in the larva state, in the nests of Anthophora, on the 12th of Sep-
