ENTOMOLOGICAL SOCIETY OF LONDON. IX 



Society's Transactions, Vol. II. PI. X. fig. 7, is exactly like it in 

 shape and size, shown as usual by the right hand line ; but the 

 species in all he had found was of a lighter hue, but this is not 

 enough he should think to allow it to be considered a different 

 species : it is more like Paussus rube}-. Six specimens of this 

 insect have now been found, and all within the last four years, of 

 which he and the younger members of his family had found five. 

 The remaining one was in the possession of Mr. Hall. All were 

 found under dry cow-dung, and in the spring. All his specimens 

 having been taken in October except the last, the fifth, which he 

 had just discovered (SOtii June) below the North Adelaide Hills 

 under cow-dung as before, he was much surprised to discover 

 it at this time in the middle of the present winter, the severest 

 and wettest they had yet had. It was softer, and the elytra more 

 pliable than the others were, perhaps from the dampness of its 

 retreat or its late assumption of the imago state. All the species 

 of this family appear to be very small. He had not seen the 

 account of the others described by Mr. Westwood, but of those 

 figured in the Transactions, the Australian one seems to be the 

 largest. He had found there one other species of this singular 

 family, much more rare, as only two had been discovered ; the 

 first by a friend about September last (1845), and the other 

 he discovered in the following month under decayed and damp 

 weeds on the ground. It is precisely of the same figure and 

 colour as the other species, but cannot be the same, unless it is of 

 a different sex, and the sexes, as in some other insects, are extrava- 

 gantly disproportionate. It is about S lines long, the other being 

 5 lines. If the other Paussidce known are no bigger than those 

 in the Transactions this species must stand at the head of them 

 with regard to size, and might be named, if not before known, 

 Cerajitcnis major or maximus. The other specimen of this fine 

 insect he had lately purchased. Of the smaller kind he gave one 

 to Mr. Fortnum when he left the colony for England, who said 

 he should give it to Mr. Hope. 



Extracts from a letter received by Mr. Spence from Mr. 

 Thwaites, stating that he had been informed by Mr. Broome, 

 M. E. S., that the truffle hunters in the neighbourhood of Salis- 

 bury assure him that the beetles which feed on the truffle (Lciodes, 

 sj}.) emit a piiosphorescent light like a glow-worm. Mr. Thwaites 

 had however suggested that the light was produced by a species 

 of Scolopendra, which always occurs where truffles abound. Mr. 

 Newport stated that the luminosity of the Scolopendra electrica 

 only occurs in the autumn during pairing time.
