COLEOPTERA SCYDMiENID.^. 279 



the subject of interesting memoirs by M. Bertrand (^Metn. d'Hist. 

 Nat. vol. ii.), in which its ravages upon the oHve trees of the south of 

 France are described; and by M. Tripaldi, in the Atti del Reallnstit. 

 di JVapoli, vol. iii. p. 139. 



The G. Cis (Jiff- 31. il. Cisbolcti) is also placed in the family Ptinidas 

 by Mr. Stephens ; but from its characters as detailed in the sy- 

 nopsis, it will be seen that it materially differs from the typical 

 Bostrichidae as well as from Anobium, with which the species are 

 often confounded [Jiff, 31. 12. represents the labrum, 13. mandible, 

 14. maxilla ; 15, antenna; and 16. tarsus of Cis boleti). The species are 

 of small size, and are found in fungi and boleti, growing upon the trunks 

 of trees, upon which the larvae subsist. I have reared Cis boleti 

 from the larvae, which nearly resemble those of the Ptinidge, and are 

 of a fleshy white colour, and of a cylindric but curved form, (Jiff. 31. 

 17. larva of Cis boleti) ; the head is scaly, as well as the mandibles 

 and six legs, but the antennae are distinct (^ff. 31. 18. front of the 

 head) ; the extremity of the body is armed on the upper side with 

 two recurved hooks, the terminal segment not being larger than the 

 preceding (^ff. 31. 19.). I have often found these insects in all their 

 states in the same fungus. The tail of the pupa is also armed with 

 a pair of minute spines * (Jiff- 31. 20.). 



The tenth family, Scydm;enid.^ f , is of small extent, and the in- 

 sects of which it is composed are of a very minute size (Jiff. 31. 21. 



* M. Bouche (Naturr/esck. der Ins. vol. i. ) has published a description and 

 figures of the larva and pupa of the same species ; but the latter scarcely convey a 

 correct idea of the insect in these states, being too much elongated, having pro- 

 bably been drawn from specimens preserved in spirits, whereby the natural propor- 

 tions of the body are lost.
