SPHEGWJE. 93 



nervures ; the head and thorax in both sexes are more shin- 

 ing and the puncturation sparser, large and shallow, post- 

 scutellum shining, largely punctured ; in the ? the disc of 

 the mesothorax is very remotely punctured ; the clypeus in 

 the ? is produced in the centre, and slightly elevated at 

 the apex, the labrum produced beyond it and widely chan- 

 nelled, the elevated apes of the clypeus can be easily seen 

 from the side ; the lunulate raised area of the propodeum 

 is narrow, well defined on both edges, subparallel-sided, 

 shining and pohshed, the legs also are less hairy ; the 

 posterior tibiae in the ? have outwardly a few short 

 irregular spines. 



L. 6-10 mm. 



Common everywhere ; usually seen basking on currant, 

 raspberry or bramble leaves. 



P. "Wesmaeli, Moraw. {lethifer, Tliovis., unicolor pars 

 S!inck., Smith, Saimd.). — Exceedingly like Shuckardi, hnt 

 slightly larger and more robust. Head and mesonotum 

 much more largely, closely, and deeply punctured, post- 

 scutellum dull, closely and rugosely punctured, clypeus in 

 the ? not raised, or produced, but with its apical margin 

 deeply emarginate, vertex of the head not narrowed behind. 



L. 7-11 mm. 



Under unicolor in Shuckard's collection both this species 

 and the preceding ai"e mixed, and they will probably be 

 found mixed in most collections. 



L. 7-11 mm. 



P. lethifer, Shuck. — Distinguished from any of tho pre- 

 ceding, by the form of the polished lunulate area of the pro- 

 podeum; this is widened in the centre posteriorly, and less 

 distinctly margined ; that is to say the punctures along the 

 posterior margin are not so crowded as in the other species, 

 and the polished area seems to bo less raised above its 

 punctured surroundings ; the clypeus in the ? is very 

 slightly produced in the centre but not i-aised, aud the 

 posterior tibia; are almost devoid of spines.
