Euglenes pygmeus. 59 
calycinus of Panzer is decidedly incorrect, that species being (according 
to Schonherr, and confirmed by Panzer’s figure) merely a variety of An- 
thicus floralis, which is a true Anthicus, and congenerous with Anth. an- 
therinus, which I take to be the type of that group. The Aderus Boleti 
may perhaps be the Wotoxus melanocephalus of Panzer,* notwithstanding 
Gyllenhal gives that insect as the female of Anthicus (Euglenes mihi) 
pygmeus as after mentioned, considering also the Anthicus ferrugineus 
of Paykull to be synonymous with the Wot. melanocephalus. It is certainly 
not the Anthicus ( Xylophilus) populneus (with which it agrees in colour), 
that species differing essentially from the Aderus Boleti in its generic 
characters, especially in those of the antenne and hind legs. 
Marsham says of his Lytta Boleti, ‘* Habitat in Boleto velutino. Larva 
** et Imago simul semper adsunt.’’ 
I beat two specimens of this interesting insect in the month: of 
September, 1826, from the oak near Ensham, in Oxfordshire; they 
ran about quickly, although not with the vivacity of the Anthici, having, 
indeed, somewhat the appearance of an Anobium. Mr. Stephens has 
since met with several specimens at Ripley, all agreeing in colour and 
geueral appearance, although I noticed that the legs and antenne of one 
of the smallest specimens were longer than in the others ; the basal joints 
of the latter organs were however similarly shaped, and I think it there- 
fore not improbable that this might be the male, and the others females.

* This is very doubtful, since, I think, that if it were the case, Gyllenhal 
would not have omitted all notice of the peculiar formation of the basal joints 
of the antennz in his description of that insect, and which he states to agree 
with the ferale of oculatus.
