ORDER COLEOPTERA. 179 



prey with their mandibles, even shoot upon it, and precipi- 

 tate it to the bottom of the hole, inclining their head down- 

 wards abruptly. They also descend there very quickly at 

 the slightest appearance of danger. If they find themselves 

 confined, or if the natui'e of the ground be unfavourable to 

 their operations, they immediately proceed to form a new 

 habitation. Their voi'acity extends even to other larvae of 

 their own species, which are established in their neighbour- 

 hood. They open the aperture of their dwelling, when they 

 are about to change their skin, or be metamorphosed into the 

 nymph-state. A part of these observations have been com- 

 municated to me by the late M. Miger, who has studied with 

 much attention a great number of the larvae of coleoptera, 

 and has discovered many which have escaped the researches 

 of former naturalists.

 iii. In length, about six lines, of a meadow-green above, 

 with the labrum, white, feebly indentated in the middle. 

 Five white points on each of the elytra. Very common in 

 Europe in the spring. 



C. Uybrida, Lin. Panz. ibid. iv. Which has on each 

 elytrum two spots of a crescent form, and a white band ; one 

 of these spots situated at the external base, and the other at 

 the end. The suture is coppery. Found in sand-pits, and 

 never mixes with the preceding species.* 



Another species of our own country, C Germanica, Lin., 

 and some others, have a form more narrow, and more elon-
