Tillus elongatus. 

 Opilus mollis. Oak. 

 Tlianasimus foiTaicarius. Bark of fir. 

 Corynetes violaceus. 



Xyletinus ater. In oak decayed to dust. 

 Ptilinus pectinicoruis. 



Trypodendron domesticum. Flying, and on bark of hirch. 

 Tomicus, three species. 

 August, 1840. Prionus coriarius. Flying in tlie evening; I have also taken the 

 larva and pupa out of birch in June, 1841. 

 Pogonochebus pilosus, hispidus and nebulosus. Dead twigs, oak 

 and birch. 

 May 24th. Saperda scalaris. One specimen on birch, a new locality for this 



insect. 



ferrea. On beech. 



Leptura scutellata and apicalis. Birch. 



elongata. I insert this in my list chiefly from the very ex- 

 traordinary varieties which appear peculiar to this forest, some 

 being nearly all black. The larva feeds on small dead (but not 

 decayed) oak boughs. The typical insect is very rare in this locality. 

 Endomychus coccineus. Under bark of birch. 

 Hypophlseus castaneus. Ditto, and in Fungi. 

 Bolitophagus Agricola, Boleti, rare. 

 Eryx niger and Mycetocharus scapularis. Old oak trees. 

 Phloiotrya rufipes. Out of oak boughs and under bark of birch. 



This insect is very active ; I met with it the end of May. 

 Ischnomera flavicollis. Whitethorn. 



Conopalpus testaceus and Vigorsii. The latter insect is said to ap- 

 pear on hedges in August, but I met with it in the beginning of 

 June. It is found in oak boughs. I have taken the larva, pupa 

 and perfect insect out of the same piece of wood ; and have beaten 

 it off oak the middle of June. 

 I am not aware whether C. flavicollis, Gyll. is identical with C. ru- 

 ficollis, Steph. but from the specimens I have taken I most cer- 

 tainly believe my insect to be the flavicollis, as all have a very 

 pale yellow thorax, especially when recently captured. I have 

 not Gyllenhall's work, therefore this is only a supposition. 

 Hylecsetus dermestoides. I first discovered this insect to be indige- 

 nous to this country on the 1st of May, 1836; between the 20th 

 and 31st of the same month this year, I was fortunate enough to 

 meet with it again. It is very variable in size; I have males and 

 females only 3 lines in length ; one female is 8J lines, but the 

 males never exceed 6 lines. It is most probable that the larvae 

 feed in birch, as Mr. Trueman of Edwinstowe assures me he took 

 a specimen just coming out from a hole in birch ; in 1836 I took 

 seven specimens on a birch stump, and this year I took it flying 

 among birches. It is only to be taken when the weather is very 

 waim and showery, with occasional gleams of sunshine ; at all
