long, and the eyes prominent. The hitesthie terminates in 

 a large cloaca, with two vesicles secreting an acrid humour. 



1. Cicindeladce. — The maxillae are furnished with an ar- 

 ticulated claw. Mandibulae prominent, straight, and den- 

 ticulated ; eyes large and full ; labium short ; tlie tibiae of 

 the fore legs destitute of a notch on the inner side. In the 

 genera Manticora, Cicindela, Megacephala, and Therates, 

 the breadth and length of the thorax are nearly equal, and 

 all the joints of the tarsus are entire. In the genus Colly- 

 ris of Fabricius, changed by Latreille into Colliuris, 

 the thorax is narrow, and produced, and the penult joint of 

 the tarsus is bilobated. 



1. CarabidcB. — The maxillae destitute of the articulated 

 claw. In general, the head is narrower than the thorax, 

 and the mandibulae are destitute of teeth. This very nu- 

 merous family has been divided by Latreille into seven 

 sections. 



1. The external maxillary and labial palpi, with the last 

 joint equal or larger than the preceding. The tibiae of the 

 fore legs have a deep notch on the inner side ; elytra trun- 

 cated or obtuse ; labium entire and oval, or nearly square ; 

 the head contracted behind, and, with the thorax, is 

 narrower than the abdomen ; the thorax is heart-shaped 

 and truncated behind, and its length never exceeds, but 

 frequently falls short of, its breadth. The section includes 

 the following genera: Anthia, Graphipterus, Brachinus, 

 and Lebia. This last genus has been subdivided into the 

 following genera by Bonelli, viz. Hellus, Cymindus, 

 Lamprias, Dromius, and Demetrias. 



2. The genera of this section exhibit the same form of 

 palpi and elytra. The head is deeply divided from the 

 thorax, to which it is joined by a socket ; the labium is 

 furnished on each side with a lobe ; the thorax rs length- 

 ened ; the penultimate joint of the tarsi frequently bilobate.
