names X. Vesparum and Vespe would lead to confusion ; and, be- 
sides, a species should not be named from a habitat which is

and the other Xenos Peckii, in honour of the two discoverers. 
Xenos Rossıı*. 
X. ater, antennis: ramis compressis, tarsis fuscis. 
. A Habitat in Vespa Gallica. 
DESCR. CORPUS atrum, fuliginosum. - 
Capvr parvum. Palpi articulo primo brevi rotundo, altero 
elongato compresso. Antenne breves vix capite longiores : 
ramis compressis et quasi ensiformibus. 
Truncvs. Tarsi (quatuor?) fusci; subtus albidi. 
XrNos PEcKII. 
X. nigro-fuscus, antennis: ramis semiteretibus dilutioribus albo 
punctatis, ano pallido, pedibus luridis : tarsis fuscis. 
Long. Corp. 14 lin. 
Hab. Larva et Pupa in Poliste fuscata Fabr. Keine 
DESCR. CORPUS nigro-fuscum, ex pube brevissima et nisi sub 
lente forti omnino inconspicua opacum et quasi velutinum. 
Capur inter antennas longitudinaliter elevatum et fere cari- 
natum. Palpi articulo primo secundo longiorit. Antenne 
capite longiores: ramis magis dilute fuscis, subdiaphanis, 
punctis minutissimis albis, et, uti suspicor, hexagonis, nisi 
sub lente forti vix conspicuis irroratis$. 
* Rossi, uli supra. 
T Professor Peck sent the measures taken by an accurate micrometer from recent spe- 
cimens, as follows: Length of the body „2, inch. Breadth of the head at the eyes 
vs inch. Length of one antenna i inch.
