388 MODERN CLASSIFICATION OF INSECTS. 



whence they have obtained the name of bloody-nose beetles. The 

 larvas (^fig- 48. 2., 48. 3. antenna), which I have found amongst moss 

 and low herbage, are very thick, fleshy, and wrinkled, of a greenish- 

 black colour, with the extremity of the body and under side dark brown 

 or blood-coloured; the legs are of moderate size ; four or five of the 

 terminal abdominal segments are furnished beneath with small raised 

 tubercles, capable of retraction, serving as prolegs, as well as one at 

 the anal extremity. When alarmed, they roll themselves up, some- 

 what in the manner of a woodlouse. They feed upon various low- 

 growing herbs; and in their general appearance and sluggish motions 

 present a striking resemblance to the imago. They undergo the pupa 

 state in the ground. SchiifFer has given a very complete account of 

 the transformations of the above-named species [Abhandl. von his. 

 vol. iii. art. 3.), under the name of the Flugellose Blattkafer. The 

 larva is described as feeding upon Galium Mollugo Linn. This au- 

 thor has also figured the larva and pupa of a Dipterous insect, which 

 was found in the pupa of this beetle. 



The species of the genus Chrysomela, and others separated there- 

 from, are distinguished by the possession of wings, and an oval or 

 rounded body. Amongst these the Chrysomela (gen. Lina Meg.^ 

 Populi (Jtg. 4^8. 4., 48. 5. labrum, 48. 6. mandible, 48. 7. maxilla, 48. 

 8. labium of this species) is one of the most common species.* It is 

 of a blue-black colour, with red elytra, tipped with black. It is found 

 upon the willow and poplar, upon which I have found its larva, which 

 is occasionally met with in society. This larva (Jig. 48. 9., 48. lO. 

 bead, 48. ll. labrum, 48. 12. mandible, 48. 13. maxilla, 48. 14. labium, 

 and 48. 15. antenna of this larva) is of an oblong-ovate form, of a 

 dirty greenish-white colour, with numerous black scaly spots ; its 

 meso- and metathoracic segments are furnished with two large lateral 

 conical tubercles, and the abdominal segments have also two rows of 

 smaller dorsal and lateral tubercles, from which, as well as from the 

 joints of the legs and mouth, drops of a fetid fluid (jf%'.48. 16.) are 

 emitted when the larva is alarmed. The eggs are deposited upon the 

 leaves in clusters. The pupa (Jtg. 48. 17.) is ovate, having the exuviae 

 of the larva? collected in a mass at the extremity of the body. 



* Dr. Hirsch of Vienna states, that this and several other beetles, which emit a 

 similar fluid when alarmed, are serviceable in the toothach, by bruising them with 

 the finger, and then rubbing the latter against the teeth and gums ; the efficacy of 

 the remedy continuing for several days upon the finger.
