Genus Pyrgotes. 
Bates, Entom. Montlily Mag. iv. 27 (1867). 
Corpus elongatum, angustum^ capite tlioraceque valde 
angustatis, Igevibus, nitidis. Antennae articulis 8-11 valde 
explanatis, a basi abrupte dilatatis, apice utroque angulo 
aeque producto. Thorax angustus, cylindricus, postice 
constrictus, post medium tuberculo laterali. Pedes validi, 
tibiae mox pone basin compresso-dilatatae. Peliqua ut in 
Piezocera (Serv., Lacord.) . 
Lacordaire, judging from the description alone, con- 
cluded that the present genus was identical with Piezo- 
cera, and even that the species might be the same as 
Piezocera hivittata, Serv. The description of the antennae 
of Pyrgotes ought to have prevented him from falling 
into this error. In fact, the form of the antennal joints 
is entirely different; both the apical angles of the third 
to the tenth being equally produced and pointed. The 
genus, in fact, is much more distinct from Piezocera than 
are Haruspex and Goryhia. Between Pyrgotes ceneus and 
Piezocera hivittata there is no resemblance of form, and 
but little of sculpture or colour.
