specimens are broader and shorter, with the antennal club not quite so strony, and 
with its second joint shorter and more transverse; the three joints preceding the 
club more transverse ; and the punctures of the striz of the elytra, and the larger 
interstitial punctures, stronger. The fourth stria, also, appears to be slightly 
sinuous about the lower third. The hinder femora, moreover, differ from those of 
the of my supposed A. grandis in being rounded off beneath, whereas in that 
insect they are distinctly angulated.—E..C. Ryr, 10, Lower Park Fields, Putney,

On a variety of Philonthus vantholoma.—Some time ago, while examining 
series of Philonthus wantholoma and P. fucicola, I was surprised to find specimens 
which appeared at first sight to be intermediate between the two species. A 
slight comparison, however, showed them to be quite different from fucicola, by 
their possessing a variegated hind-body,* and a pale margin to the elytra. These 
specimens differ from xantholoma by being larger, by possessing a very large and 
very variosely punctured head, by the thorax being narrowed behind, and the 
under-face of the hind-body sparingly and coarsely punctured. This last character 
is so striking that I supposed the specimens possessing it to be a distinct species 
from zantholoma, till a letter from Mr. Rye induced me to look at my examples 
again, when, on un-mounting all of them for examination, I found all to be males. 
These males differ strikingly from ordinary males of xantholoma, by the characters 
mentioned above. Though the size and development of the head varies considerably 
in these individuals, the punctuation of the under-face of the hind-body remains 
constantly quite different from that of ordinary g wantholoma. Inthe absence of any 
females, however, these cannot be looked on as a distinct species; and it would 
appear that P. zantholoma is a species possessing two distinct forms of the male 
Sex, one resembling the female in all points, and distinguished therefrom only by 
the emargination of the sixth and seventh segments, and the other differing by 
the characters mentioned above. Should it be thought well to give a distinct 
name to this remarkable variety, it may be called P. variolosus. This form is, 
according to my experience, much rarer than ordinary zantholoma, though I have 
found it at various places on the coast in England and Scotland. The large headed 
males from Berwick, alluded to by Kraatz in the Ins. Deutsch., ii, p. 596, are no 
doubt to be referred to it; as is also the figure of P. zantholoma in Du Val’s 
Genera.—D. Swarr, Eccles, Thornhill, Dumfries, December, 1870. 
Note on Trogophleus bilineatus, Steph.—There is a confusion existing as to this 
species which requires correction. In his Illustrations, Stephens describes and figures, 
under the name Carpalimus bilineatus, an insect beyond question the 7’. riparius of 
Lacordaire and Erichson; and this name, haying priority, must be adopted. 
Hrichson, misled by a specimen of another species sent by Spence as bilineatus, 
described under that name another species, and it becomes necessary, therefore, 
* Although it is customary, when speaking of this part in the Brachelytra, to call it the abdomen, 
this is clearly a mistake. Though there may be some reason for speaking of the under-surface of the 
hind portion of the body among the Coleoptera as the abdomen, there can be none for calling by that 
name the exposed dorsal portion of the hinder segments. The Germans use the word ‘ Hinterleib” 
for the part we speak of as abdomen; and it would perhaps be an improvement if we were to use the 
equivalent ‘‘ hind-body,’’ or some such word. If any one can suggest a better name than this, I shall 
_ be much obliged to him.—D. 8.
