Miscellaneous. 235 



M. Eimer has proved a tendency to the appearance in the variety 

 ccerulea of characters of the squamation, which manifest themselves 

 in the region where the dorsal granules abut against the ventral 

 plates. Another difference, which is not, however, quite constant, 

 shows itself in the number of femoral pores, which vary from 21 to 

 25, while in the typical L. mural is we rarely count more than 20. 



Lastly a very curious peculiarit} 7 of the individuals of this variety 

 is their want of fear of man, which is above all interesting if one 

 compares it with the extreme shyness of their cousins in Capri. 



When kept in captivity the representatives of the two varieties 

 show affinity towards those of the same form as themselves and hos- 

 tile dispositions towards those of the other form. 



It appears from these physical and moral characters that the form 

 discovered by M. Eimer would be distinct enough to merit, in the 

 eyes of certain zoologists, the title of a species, while on the other 

 hand its affinities and its habits clearly show from what root it has 

 sprung. It furnishes a striking example of what has been called 

 an "incipient species." — Bibl. Univ. April 15, 1875, Arch, des Sci.

New Tertiary Pleurotomaria. 



To the Editors of the Annals and Magazine of Natural History. 



Gentlemen, — I greatly regret that, in sending you a notice lately 

 of a new Tertiary Pleurotomaria, I lost sight of the fact that Gold- 

 fuss and Deshayes had also each found a species of the same age 

 many years ago. Your most obedient Servant, 



Melbourne, Frederick M'Cot.

Note on the Larva of a Lonc/icorn Beetle (Clytus quadripunctatus, 

 Fabr.). By Charles O. Waterhotjse. 



The larva of this insect was brought to me about two years ago. 

 It had been found feeding upon ebony, and appeared nearly full- 

 grown, measuring two thirds of an inch in length. Understanding 

 that this larva would also eat sycamore, I bored a small hole in a 

 piece of an old stand made of that wood and placed the larva in it, 

 on October 7th, 1873. The perfect insect, a female, emerged from 

 the wood on the 14th of August, 1875. The length of time that this 

 example remained in the larval state may have been increased by the 

 great dryness of the wood in which I placed it, the stand having been 

 in use in the British Museum thirty years ago. As I have not met 

 with any description of this larva, I subjoin the following note, made 

 at the time the larva was received : — 



" Mandibles black ; clypeus transverse, rounded in front, pitchy ; 

 labrum white, rounded in front, narrowed towards the base ; basal 

 joint of maxillary palpi twice as broad as long, second joint nearly 

 globular, apical joint very small and acuminate ; antennae very short, 

 with only three visible joints, the basal one elongate slightly nar- 

 rower at the base, second joint a little longer than broad, third joint
