development of which I propose to myself, some time or other, 

 to say a few words, and to establish certain diagnoses,, as^be- 

 tween Ilybius guttiger and angustior. In the present case, 

 in I. fenestratus, we have a mere triangular notch on the 

 under surface of the last abdominal segment, and a ridge ex- 

 tending from this ; whereas in H. subaeneus we have a notch, 

 hut with the niargins of it Jlattened in the most remarkable 

 manner, and no distinct ridge connected with it. Of British 

 subaeneus we have as yet but one specimen, a female, and 

 therefore the comparison is not decidedly satisfactory. I 

 trust that more specimens will be obtained by our friend 

 Mr. Newman and his neighbours. 



At Lee I have also myself found a species of Pachyrhinus 

 (Phytobius) not yet described as British. We have in our 

 catalogues Pachyrhinus 4-nodosus. Now 1 found at Lee 

 some six specimens of a species living only in marsh-ground, 

 lai'ger, more coarsely tuberculated, and with shorter thorax 

 than one which I hnd at Mickleham, Reigate, &c., on dry 

 and chalky places. The latter is no doubt the Pachyrhinus 

 4-nodosus of Waterhouse's ' Catalogue.' Mr. Crotch, at my 

 request, took both species over to Paris, and M. Brisout de 

 Barneville returned the Lee specimens as Phytobius 4-nodo- 

 sus, and the Reigate and Mickleham specimens as Phytobius 

 denticoUis. We have therefore, at any rate, a netf species, 

 which, as far as I can judge, must take the name already 

 existing in our catalogues ; whilst the old one must take a 

 new name, viz., P. denticollis.

Description of the Larva of Chelonia Plantaginis. — The 

 egg is laid in June, on the under side of the leaf of Plantago 

 major (broadleaved plantain), on which plant the larva feeds : 

 by the end of August it has attained a length of from half to 

 three-quarters of an inch, and may then be found on the 

 under side of the leaf, its presence being indicated by a 

 nearly circular hole in the disk, or a notch on the margin of 

 the leaf: when touched it falls from its food-plant, feigns
