Although Drypta is related to Odacantha (Plate 227.) it is 
easily distinguished from it by very important differences in 
the trophi, as well as by the bilobed penultimate joints of the 
tarsi, and the great length of the basal joint of the antennae is 
a character not to be met with in any of our Carabidse. A 
considerable similarity is observable in the Jabrum and max- 
illae of our genus and Cicindela, but the mentum and labium 
as well as the apical joint of the antennae, are totally different 
to any which have come under my observation, and the sin- 
gular structure of the latter has never been noticed by any 
other author ; it seems to be formed for fastening itself by its 
horns to an object, but whether it be sexual or not I am unable 
to determine. 
There are only 8 or 10 species of this pretty genus known, 
and it is remarkable that they should be distributed to the 
remotest parts of the Old World, from Europe to Africa and 
the East Indies, and even New Holland. The only species 
inhabiting Great Britain is 
D. emarginata Fab. — Curt. Brit. Ent. pi. 454. 
Bright greenish blue, trophi and antennae rufous, the latter 
with the apex of the 1st and 3rd joints, sometimes the middle 
only of the latter, black ; eyes blackish : head and thorax co- 
vered with large and deep punctures, the latter with a strong 
channel down the back; elytra pubescent and minutely punc- 
tured, with 10 firmly punctured striae on each, that next the 
scutellum abbreviated, but longer than usual; abdomen black 
above ; legs ferruginous-ochre, tarsi slightly fuscous. 
Specimens of this rare and handsome Insect have been taken 
in May and June near Hastings, and at Feversham in Kent; 
it is stated also by Mr. Hope to have been taken under marine 
rejectamenta on Leith sands near Edinburgh. It is found in 
moist woods and marshy places at the roots of Sallows and 
under stones ; it is very rare in the neighbourhood of Paris, 
but abundant near Bordeaux and Castelnaudary in the South 
of France. 
The Plant is Hippophae rhamnoides (Sea Buckthorn), 
communicated by James Paget, Esq., of Yarmouth, Norfolk.
