68 MODERN CLASSIFICATION OF INSECTS, 



Dr. Heer states, that the larva of Cychrus rostratus {Jig. 3. 3.), " 3 

 Caraborum larvis capite parvulo, palporum articulis exteriorlbus eras- 

 sioribus, mandibulis erectiusculis, et corporis forma breviori latiorique 

 facile distinguitur ; " in addition to which the prothorax is conical, 

 and the anal segment very short, with the hinder angles prominent, 

 and armed in the middle with two very short and simple spines. 



De Geer has figured a larva {Memoires, vol. v. pi. 12. f. 1 — 3.) closely 

 resembling that of Calosoma, which was found in the ground, and 

 which he presumes to be the larva of one of the species of this 

 family. He was not, however, able to rear it. 



In the first edition of the Coleopteres dEurojiC, M.Latreille announced 

 a memoir upon a larva sent to him by M. Westermann from Bengal, 

 supposed to be that of Anthia Q-guttata. This larva, since the death 

 of Latreille, has been described and figured by M. Lequien in his Mo- 

 nograph upon Anthia, published in M. Guerin's Magasin de Zoologie, 

 Insecfes, pi. ^l., and by Messrs. Audouin and Brulle, in their Histoire 

 naturelle dcs Insectes. It is nearly three inches and half long {Jig. 2. 8-) 

 with a subcylindric scaly body, consisting of twelve segments, exclu- 

 sive of the head {Jg. 2. 9. under side of head), which is armed with 

 strong acute mandibles, very short three-jointed antennae, and a 

 single pair of eyes ; the upper side of the head is rugose with several 

 tubercles in front ; the terminal segment is scabrose, serrated at the 

 sides, with a deep notch at its extremity ; this segment is furnished 

 beneath with a single fleshy anal proleg. The second ? and nine fol- 

 lowing segments are respectively furnished with a pair of lateral 

 spiracles ; the mentum and maxillae are long and extend almost to the 

 base of the head. The legs are short. This larva is of a black colour, 

 with the posterior margins of the segments obscure red. It has not been 

 stated upon what grounds this larva was considered as that o^ Anthia 

 6-guttata, and indeed upon comparing the details of its structure, 

 and especially its trophi, with that of the known Carabideous larvee, 

 I have no doubt that it does not even belong to any of this family; 

 since, in its general appearance and organisation, it approaches much 

 nearer to the larvae of the ElateridcB.^ 



* Since the above was written, I liave received the following communication from 

 M. Westermann himself, relating to this larva, in answer to the inquiries which I 

 was induced to make concerning it : " With the greatest pleasure I shall give you 

 all the information in my power of the circumstances which led me to believe that 

 the larva I brought from India, and sent to the late M. Latreille, was that of Anthia 

 6-guttata. M. De Ilaan of Leyden made a similar inquiry last year, and I informed
