the egg, and that in which he has found it, immediately before it 

 changes to a nymph. He did not however describe them as actually 

 the young of Meloe, and he now finds that they belong to another 

 family, the Engidts. 



The author then describes these larvae more minutely, and states 

 that having kept them in a glass vessel partly filled with dry clay 

 and a cell of Anthophora retusa which contained a nymph, he found 

 that the larvae constantly sheltered themselves beneath it, although 

 they did not attempt to prey on it, but fed on the rejectamenta 

 voided before it underwent its change. The larvae continued in this 

 state till the beginning of January, when each specimen quitted the 

 cell of the bee, and excavated for itself a burrow in the clay in which 

 it assumed the nymph state. The nymph closely resembled that of 

 Diaperis Boleti in its general appearance. 



At the end of February each specimen assumed the imago state, 

 but continued feeble, and remained in its burrow until the eighth of 

 March, when it came forth and proved to be Cryptophagus cellaris, 

 Payk.

Lores, space beneath the eye and the chin deep black ; head, neck 



and upper part of the back brownish grey ; lower part of the back 



and the wings dark grey, becoming gradually deeper towards the tips 



of the feathers ; primaries and secondaries narrowly edged with white

and abdomen pale grey, passing into white on the under tail-coverts ; 



upper tail-coverts and tail black ; the apical third of all but the two 



middle feathers white ; irides dark brown ; bill yellowish horn-colour, 



becoming black at the tip ; feet blackish brown.

 Remark. — This species differs from the A. cinereus, to which it is 

 most nearly allied, in the white colouring of the abdomen and under 

 tail-coverts. Two specimens have come under my notice, both of 

 which were killed by Mr. Gilbert, one on the Darling Downs, in New 

 South Wales, and the other at Peak- range Camp, one of the stations 

 so named by Dr. Leichardt during his expedition from Moreton Bay 

 to Port Essington.
