instead of fauna. It is well that Mr. Babington has called 

 fig. 49. a Scolytus ae^neus, otherwise tyroes might have thought 

 he intended it for the true rtificoWis ; as Mr. Babington, in 

 V. 330., describes the red part of the elytra as exceeding one 

 half, which is not the case in his figure of rz^c611is d, Mr. 

 Babington also describes bipunctatus Bab. as having, near the 

 apex of each elytron (V. 329.), " an impressed slightly lunate 

 black spot; " but, Mr. Westwood (VII. 379.) says, " of the 

 extremity of the elytra, which thus appear to be appendix 

 culated in both sexes of this species," as in bituberculatus. 

 I have taken four individuals of a species nearer to rw^collis 

 Pz, than the others, at different times, near the Meres ; one 

 last year, near Ugg Mere. They all appear to be ? : but the 

 red part of the elytra is scarcely so much [large] as in Panzer's 

 figure ; and at the extremity of one of them is a dusky spot, 

 which approaches so near Mr. Babington's description, except 

 the impression, that I had thought [VII. 178.] it was the 

 same ; but I now find it to be distinct. I have taken three 

 of M. bituberculatus in the New Forest : one in May last. —

Helbbia Mars/iallkna. — Specimens of this species were 

 found under stones, on the summit of Skiddaw, in great 

 abundance, on Aug. 27. 1832, by our correspondent E. Wil- 

 son, jun. For the state of the weather at the time, see p. 539. 

 Scolytus destructor Olivier (Jig. 63. a, natural size ; d, mag- 

 nified) is not a Destroyer of healthy Trees. The Trees into 



whose Bark the parent Scolytus per^ 

 forates to deposit her Eggs, that the 

 Larvce hatched from those Eggs may 

 feed upon that Bark, are diseased 

 dying Trees. — The grounds of this 

 opinion are detailed in IV. 153. 

 (Letter B.) — 156. An opportunity 

 for testing it now offers itself to any 

 entomologist of London, in a case 

 to which the following circumstances 

 appertain. On the north side of 

 Hyde Park, a belt of trees is situate 

 alongside the boundary fence in the 

 Park, and of the length of it. This 

 northern boundary fence was, so 

 lately as 1832, constituted in a cer- 

 tain part by an old brick wall, now 

 removed. The point atwhich the old wall commenced may 

 be stated at about 300 yards west of Park Lane, and it
