. Annals of natural history. Natural history; Botany; Zoology; Geology. 4-8 MODERN CLASSIFICATION OF INSECTS. The first family, Cicindelid^ Leach, is distinguished by the terminal hook of the maxillae being articulated at its base (^fig> 1. 3.): the head is large and broader than the thorax {fig. 1. l. Cicindela. campestris, the common green tiger-beetle): the eyes are very large and prominent: the mandibles 1.2.) very large, acute, and armed with several strong teeth: the palpi are not longer than the man- dibles : the lower lip is concealed by the broad mentum (^fig. 1. 4.); and the labial palpi (which are three-jointed, appearing to arise from a moveable base, and are densely clothed with white hairs), as well as the legs, tarsi, and antennae, are long and slender: the anterior tibiae are not notched on their inner side, and the penultimate segment of the abdomen is often notched in the males : the anterior tarsi of the males are often broader than in the females {^fig. 1. 5., anterior tarsus Cicindela $—1. 6. ditto ? ). Of these characters, that afforded by the slight development of the labium is, perhaps, the most valuable, although that of the articulated terminal maxillary hook has been chiefly relied upon; but M. Audouin has recently observed, not only that in the genus Ctenostoma the hook is entirely wanting—as, indeed, I had previously noticed by dissection (^fig. I. lo.)—but also that, in the Carabideous genus Trigonodactyla, the hook is distinctly articu- lated. In the genus Stenocera Bridle, (Pogonostoma Klug, ) the hook is also wanting. The Cicindelidae generally frequent hot sandy districts; where they may be observed flying in the sunshine with great velocity; whence Messrs. Kirby and Spence have termed them Eupterina. Their flight is, however, of short duration; but they immediately take wing again on approaching them. From the brilliancy of their colours they have been termed sparklers, whilst the name of tiger-beetles has also been conferr
