Insects. 1995 



sen has recently verified the statement of the old author, and observed the circum- 

 stances of this association more particularly. From a nest of Bombus Scrimshiranus, 

 which he had brought into the house that he might make his observations on the bees 

 more easily, he obtained but two bees (both workers), while as many as seventy-six 

 of the Mutillae, forty-four males and thirty-two females, came out of it. Their grubs 

 were found alone in cells closed with the usual web, and as the grub of the bee only 

 can produce this, it appears that the Mutilla is carnivorous, devouring not the provi- 

 sion laid up, but the full-grown grub of the bee. The female Mutillae pass the win- 

 ter torpid and rolled up in burrows under ground, while the males die off immediately 

 after pairing. — Journal of Ent. Soc. of Stettin, 1847, p. 210.

Capture of Pytho depressus, Cetonia cenea, fyc, in Scotland, and of Rare Insects 

 elsewhere. — Although the addition of a new species to our Fauna, amongst the Verte- 

 brata, is an event of sufficient importance to record in the pages of the ' Zoologist,' I 

 doubt whether such be the case in regard to the countless numbers amongst the Inver- 

 tebrata ; nevertheless exceptions, as in the present instance, may occur. As exam- 

 ples of the extent of unrecorded indigenous insects, I shall mention two, viz. — in two 

 limited groups of Diptera — the Sarcophagiens, and a portion of the Muscies of Mac- 

 quart, forty-seven species only are recorded, whereas, ten years since, when I re- 

 arranged that portion of my collection, I possessed eighty-three described ones, there- 

 by adding thirty-six, which, with additions, remain to this moment unrecorded ; while 

 the insects themselves are generally of large size, Musca domestica being about the 

 smallest, and most of them are found, moreover, within or about the metropolis.
