As the females of this species are the most numerous, and are most likely to be met 
with, I have regarded this sex as affording good generic characters, although those of the 
male are the most extraordinary. The name I propose for the species is 
ANTHOPHORABIA RETUSA; Fem. (Tas. VIII. fig. 2.) Æneo-viridis, capite magno, oculis 
compositis nigris, abdomine nitido ovali, alis magnis rotundatis, pedibus flavescenti- 
bus. Mas. (fig. 1.) Flavus vel saturate ferrugineus, capite magno rotundato ocello 
utrinque unico tribusque in vertice instructo nigrescente, pedibus robustis.— Long.

In the month of August 1831, while examining the dry clay bank beneath the ruins of 
the Roman castle at Richborough, near Sandwich in Kent, in search of the larvæ of Meloe 
in the cells of Anthophora retusa, with which the bank was thickly perforated, I found 
many cells filled with an abundance of minute parasitic larvee, about one line in length, 
and apparently full-grown; but scarcely a cell contained any vestige of its original inha- 
bitant, the larva of Anthophora. During that autumn and the following spring I met 
with these parasites so frequently in the cells, in diffepent stages of development, that 
although I regarded them at that time as a new species of Chaicidide, I took little heed 
of them, as my chief object then was to obtain the Meloés, and as I expected to find them 
on future occasions in equal abundance. Indeed they were so common as to occasion me 
considerable annoyance in finding the cells filled with these intruders instead of the larvee 
of Anthophora or Meloé. I took care, however, to make very precise drawings of both 
sexes, in the perfect state, and of the larva, and also entered some notes of description. 
In the following years, 1832 and 1834, I again met with them, more especially on the 
21st of August in the latter year, but not in such profusion as at first; but I have not 
been able to procure them since that period. 
The larva (fig. 3) is completely apodal, of a sub ; 
extremity, and composed of fourteen segments. The head is small, like that of the wasp, 
or hornet, and the mandibles are short and acute. It occurred in the bee-cells to the num- 
ber of thirty or fifty in each. I found it not only in the autumn, but also in the winter 
and early spring, in this state, but in some cells the larvæ had changed to nymphs before 
the month of September. :
