COLEOPTERA. — HELOPIDiE. 311 



Bouclie has given figures of the larva and pupa of this insect, evi- 

 dently taken from specimens in spirits, and consequently greatly atten- 

 uated; the pupa is distinguished by having the lateral margin of the 

 abdominal segments furnished with a small flattened and spinose 

 lobe. Kyber has also given an account with figures of the last named 

 species in its different states in Germar's Magazin der Entomologies 

 vol. ii. tab. 1./^. 8— 11. 



The larva and pupa of Mycetocharus axillaris, foiiiid in rotten apple 

 trees, have been figured by Bouche (^Naturg. pi. 10. f 1 — 11.); but 

 do not offer any apparent variation from those of Eryx niger. The 

 larva of Myct. scapularis, from rotten oak, is figured by Mr. G. R. 

 Waterhouse {Ent. Trans, i. pi. 5. f. 3.), and also equally resembles 

 the former. These larvce are furnished with two anal prolegs. 



Solier divides this family into two sections, Cistelites (with bifid 

 mandibles, and securiform maxillary palpi) and Cteniopites, with 

 entire mandibles and maxillary palpi scarcely securiform. 



The second family Helopid/e * Stephens {fig. 36. 13. Helops cara- 

 boldes), consisting, however, of exotic species, is very extensive, chiefly 

 distinguished from the preceding family by having the tarsal ungues 

 not serrated, and from the following by the structure of the antennae, 

 which are filiform, and the elytra not soldered together ; the head 

 is short, and immersed as far as the eyes in the thoracic cavity 

 {fig- 36. 14.) ; the antenna^ are concealed at the base b}' the lateral 

 margins of the head, with cylindrical or reversed conical joints, the 

 third being the longest ; the mandibles {fig. 36. 16.) are short,
