COLEOPTERA. M YCETOPH AGIDTE. 1 55 



Lond. i. p. Iv.) have published some observations upon the supposed 

 attacks of this insect upon the corks of wine-bottles in cellars. 



The transformations of Latridius * lardarius have been described and 

 figured by De Geer (^Memoires, vol. v. pi. 2. f. 25 — 31.), who found the 

 larvtje in a dried pig's bladder ; they arc white, with a dark line down the 

 back {Jig. 13.22.), having the body moderately long, narrowed towards 

 the posterior part, the articulations being deeply incised, and covered 

 with moderately long hairs ; the head is small, and the terminal seg- 

 ment is small, entire, rounded, and provided beneath with an anal 

 proleg. These larvae underwent their changes in a glass bottle, 

 against the sides of which they attached themselves by the extremity 

 of the body, where they became small pupae, clothed with rather 

 long hairs, having a small knob at the extremity of each. 



Kyber has also given a long account of the transformations of La- 

 tridius porcatus in the second volume of Germar's Magazin der En- 

 tomologie, in which the larva is represented with a much larger 

 head, and the segments of the body more contracted than in De 

 Geer's figure. These larvae fed upon the mucor found upon vegetable 

 and animal substances, and were particularly fond of the radish (lla- 

 phanus sativus) ; they were also found upon the corks of bottles, 

 which they probably also fed upon. The larvas lived from March to 

 the middle of May, at which time they changed to pupae, fastening 

 themselves to the sides of the glass, in which they were confined, by 

 their tails, with their heads uppermost, in which state they remained 

 fourteen days. 



The seventh family DERMEsxiDiEf Leach, having for its types the 

 chief species of the Linnaean genus Dermestes {Jig. H-^ i. Derm, lar- 



* My figure 13. 20. i-eprcscnts a new species of this genus, which may be tlius 

 named and characterised Latridius, nodifer, j)iceo-niger, thorace angusto bicostato 

 pone medium constricto ; elytris striato-punctatis, pone medium bituberculatis. 

 Long. Corp. 1 lin. Found at Chiswick and Coombe, at the bottom of whitethorn 

 hedges in the autumn.
