made in Dr. Gistl's Systema Insectorum that one 

 of the species feeds on vegetation. Is this a pecu- 

 liarity of the genus or not ? 



8. Plochiocera, Hope. 



I have separated the Cic. nodicornis D. J. from 

 Odontocheila of Laporte, and have formed it into a 

 subgenus, attaching the name of Plochiocera, derived 

 from ttXoklos twisted, and Kepas. In habits it 

 resembles the former genus, it differs chiefly in 

 having the first article of the antennae of the male 

 dilated, or knotted, and in the truncation of the 

 front of the short upper lip. In other respects it 

 accords with Odontocheila, which has the upper lip 

 as long and acute at the tip, as in Oxycheila. 



9. Cicindela, Ziinneus. 



After detaching Odontocheila from Cicindela 

 more than 200 species remain huddled together 

 under that term. The Baron De Jean has attempted 

 sundry sections ; they are not however characterised, 

 and still remain in great confusion. Cic. analis Fab. 

 affords from its form and 7-toothcd labium sufficient 

 marks for forming a sub-genus, and might appropri- 

 ately be named Heptodonta.
