2. collaris, Thorns. 



I.eptoaypius (o/laris, Thonis. O. E. xxi. 2388, 9 • 



Head strongly iiitidulous and black, with the centrally impressed, broad 

 and glabrous clypeus red ; vertex hardly narrowed behind the eyes ; face 

 sparsely pubescent, palpi stramineous. l''lagelluni brunneous, with the 

 scape paler beneath. Thorax black, with the prothorax and elongate 

 callosities before the whitish radix red ; mesonotuin nitidulous and convex, 

 with distinct and discally coalesced notauli ; metathorax sparsely pubes- 

 cent, with complete upper areae, of which the areola is elongate and 

 apicaliy acuminate ; petiolar area not discreted, apophyses minute. 

 Scutellum convex and black. Abdomen elongate-ovate, ferrugineous with 

 the first and base of segments two to four piceous, remainder black ; basal 

 segment linear and scabrous-striolate with distinct tubercles, the three 

 following deeply incised and, except apicaliy, coriaceous with the second 

 aciculate ; terebra as long as the petiole and strongly reflexed. Legs pale 

 and slender ; the anterior testaceous, basally paler ; hind ones red with 

 the trochanters, tarsi and base of tibiae hardly darker. \Vings normal 

 with the areolet sub-entire, nervellus opposite and not intercepted. 

 Length, 4I mm. 



There can be no doubt that a female taken by Bignell at Plym bridge 

 on 7th August, 1884, and labelled "Genus query," is referable to this 

 species, which has not before been noticed outside Sweden ; I am also of 

 opinion that Dr. Capron took a single female at Shere in Surrey. It is 

 strange, however, that Thomson makes no mention of the peculiarly dis- 

 tinctive sculpture of the abdomen ; and at first I had thought it the 

 unknown $ of P. fetierrwuis, on account of its aciculate second segment. 

 It may still be so, for Thomson's $ bears many features in common with 

 that species.
