Genus Pyrgotes. 



Bates, Entom. Monthly Mag. iv. 27 (1867). 



Corpus elongatum, angustum, capite thoraceque valde 

 angustatiSjlaevibuSj nitidis. Antennae articulis 3- 11 valde 

 explanatisj a basi abrupte dilatatis^ apice utroque angulo 

 seque producto. Thorax angustus, cylindricus, postice 

 constrictus, post medium tuberculo laterali. Pedes validi, 

 tibige mox pone basin compresso-dilatatge. Reliqua 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 bivittata, Serv. The description of the antenna 

 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 cenetis and 

 Piezocera bivittata there is no resemblance of form, and 

 but little of sculpture or colour.

 neus, elytris (marginibus angustis exceptis) laete viridi- 

 aeneis; thorace nitido, impunctato, nigro-setoso, medio 

 nigricanti sericeo ; elytris sparsim punctulatis, apice 

 oblique truncatis, angulis rotundatis.
