 WITH NOTES. 



BY G. H. VEREALL, F.E.S. 



{Continued from vol. xxiv, page 112). 



Dolichopeza sylvicola, Curt. : I believe this curious and elegant 

 insect occurs all over Great Britain, in suitable spots ; I have met 

 with it as far north, as Tongue, and also in "Wales, the Lake District, 

 Hampshire, and Sussex. It occurs on damp overhanging banks when 

 in shade, or on the tops of water tunnels, where it may often be seen 

 hanging by two legs only. It is an interesting study as to what the 

 " protection " is, that is afforded by the pure white feet, a character 

 which in some modification seems to occur in most (if not all) the 

 allied species. The only suggestion I can make is that the insect 

 having smoke-coloured wings and body, is practically invisible in the 

 gloomy spots in which it flies, while the widely outstretched white 

 feet leave six evident streaks, at which any insect-eating bird might 

 snap, and then the legs being most wonderfully fragile, the insect 

 itself would escape with the loss of a foot ; against this I must admit 

 that I have never seen a mutilated specimen. The adhesion of the 

 legs is so slight that the insect requires pinning within a minute of 

 death, if any legs are to remain on it. 



Nepkrotoma dorsalis, Mg. : I know only from specimens in the 

 British Museum. Osten-Sacken would sink the genus in Pachyrrhina, 

 from which it differs only in having more joints to the antennae.
