C3aO PHILOSOPHICAL TRANSACTIONS. [aNNOISQS. 



post, and made the noise like a watcli, by beating its head on the subject that 

 it finds fit for sound. This was answered by another in the same room, and 

 after a minute's distinct beating, would forbear for the other to answer. The 

 part it beats with is the extreme edge of the face, which I may call the upper 

 lip, the mouth being protected by this bony part, and lying underneath, out of 

 view. 



It was -rV of ^" '"ch long; the colour a dark brown, with spots somewhat 

 lighter, irregularly placed, which would not rub off readily. They seemed to 

 lie rather athwart the back, and direct on the head, as in the small figure, 

 (fig. 8, pi. 5) which is much of the same size with it, and the maculae are 

 designed for the greyish spots. Under the vaginae are pellucid wings, and the 

 body is of a dark colour. The head appeared large, by reason of a large cap or 

 helmet which covered it round, only turned up a little at the ear ; from under 

 this appeared the head, which was fiat and thin ; the eyes forwards : the lip hard 

 and shining ; the bars of the helmet greyish. Two antennae proceeded from 

 under the eyes, which, by their meeting on the breast, I conjectured to assist 

 their feeding, and to be rather probosces ; and the helmet to be turned up for 

 the sake of hearing, and the belly plicated as other beetles. The other beetle 

 that answered it was less, and the marks on the back not so distinct. 



By the microscope I discovered the marks to be thickest spots of hair of a 

 castor colour : the head all hairy, and face full of curled hair. On the belly was 

 some hair thinly set. The eyes appeared large, as in fig, g, drawn from the 

 microscope. The superficies consisting of many small squares furrowed deep 

 between, and these lay in lines transversely descending towards the nose ; these 

 eyes were not moveable, but contiguous to the face, without any cavity to re- 

 ceive them, and they were very opaque. The antennas preceeded from under 

 the eyes, the first large joint having a cavity, out of which it proceeds at the 

 sides of the lip. Between the eyes the face rises in a little ridge, which is tile 

 nose, and is signified by the light part of the face; and just below, the nostrils 

 are covered by straight pendulous hair proceeding from the lower ridge of the 

 nose ; under this hair the cavity is dark, below the nose the lip shades show the 

 more depressed places; under this lip are forcipes, to lay hold on its food, 

 two on each side. 



On an Eruption of Fire out of a Spot in the Eartk near Fierenzola in Italy. 



By Dr. Rob. St. Clair. N° 245, p. 378. 



I lately received an account from my brother, that on the side of one of the 



Appenine mountains, half way between Bologna and Florence, near a place 



called Petra Mala, about 5 miles from Fierenzola, there is a spot of ground,
