basally more broadly red, llic a[)()i)hyscs more prominent ; die o is a 

 more slender insect with the abdomen paler and less claviform than that 

 of P. dnmetorum. 



An abundant species, both here and abroad, often flying in woods on 

 hot days, from May to September ; sometimes on Scabiosa and Ant^elka 

 flowers. I have records from the London district, New Forest, Shrop- 

 shire, Scotland, Maldon in Essex, Norfolk, l^xminster, I^and's ICnd, York- 

 shire, Huddersfield, Lyndhurst, Abinger Hammer, Shere, CIreenings and 

 Chobham. I'^Uiott has sent it me from Haybmii W'yke ; and I have found 

 it in Suffolk, at Shrubland Park, Barton Mills, Henstead, I'inborough 

 Park, Pentley Woods and Tuddenham Fen. It has also been taken 

 at Rossbeigh, in Co. Kerry, by Donisthorpe, and Kingsdown, in Kent, 

 by Sladen. Thomson says it has been bred from di[)terous (probably 

 Tachinid) pupae. The brachypterous form is not common and I have 

 not seen its male ; Piffard has twice taken it at Felden in Herts. ; late in 

 August, 1900, Butler sent it to me from Abinger Hammer in Surrey ; and 

 I have recently examined a specimen which Rev. O. Pickard-Cambridge 

 bred from the eggs of some Epeirid spider in Dorsetshire.

Head black and palpi red ; antennae immaculate, half as long again as 

 the body. Metathorax irregularly rugose ; areola small, sub-c[uadrate, 

 with the basal costa obsolete ; centre of the petiolar area coarsely and 

 transversely rugose, not discreted. Scutellum black. Abdomen narrower 

 than thorax, oblong-ovate ; black with segments two, three and more or 

 less of the fourth, red ; basal segment canaliculate, with weak carmae and 

 tubercles ; post-petiole foveolate and gradually dilated towards the apex. 

 Legs normal, black ; trochanters entirely, tibiae exce[)t apices of the hind 

 ones, tarsi except apices of the hind ones and all the onyches, red ; a[)ices 

 of the anterior femora ferrugineous. Wings often slightly clouded ; radix 

 flavous, tcgulae black. Length, 7-8 mm. 



This cj,- which appears to have only been shortly described by Clraven- 

 horst and Taschenberg, is said to resemble P. fu/iia/or, but is more 

 elongate, with the antennae longer and the legs differently coloured. It 

 is impossible to conjecture its true position from the above meagre 

 description, and it would, i)erhaps, be better to omit it from the British 

 list, if such a course were permissible. I do not fmd that it has been 

 noticed on the Continent since 1829. 



(iravenhorst then took it in dermany, on the flowers of Pastinaica 

 sativa, in June and August ; Stephens says it was not common in June, 

 about London, and Marshall records it (I'^nlom. 1872-3, p. 432) as having 

 been taken by Francis Walker, in the Isle of Man, in 1869.
