 near Hastings.

Closely allied to the last-described species. Head somewhat narrowed 

 behind the eyes, black ; mandibles bidentate, slender ; $ with palpi, sides 

 of face, and sometimes the ang'es of the truncate clypeus, white. An- 

 tennae setaceous, black ; of 9 white-banded with the eighth flagellar joint 

 quadrate ; scape of $ white beneath. Thorax black with white lines 

 before and beneath the radix ; areola semi-elliptic, a little longer than 

 broad ; costulae obsolete. Scutellum white. Abdomen closely and finely 

 punctate, of ? elliptic, of $ sub-linear, black ; segments two and three 

 clear red or, of $ , flavescent ; five to seven and sometimes the fourth 

 broadly white-margined ; the third of $ transverse, black-marked ; post- 

 petiole aciculate ; gastrocaeli small ; fourth ventral segment of $ plicate. 

 Legs normal, black ; tibiae and tarsi, except apices of the posterior, and 

 part of the front femora, red ; hind tibiae of $ sometimes fiavous. Wings 

 flavescent, stigma fulvous. Length, 12-15 mm. 



Extremely similar to the preceding ; Thomson says the sculpture, size, 

 colour, etc., are nearly identical, but that the front femora beneath, and 

 the intermediate at the base, are more broadly black, the fifth segment has 

 an apical line, the sixth a dorsal mark, and the seventh is a little more 

 broadly, white. 



This species occurs in France and Germany, in June. Stephens says it 

 is very rare, near London, and no subsequent observers appear to have 

 noted it.

Head usually somewhat small ; mandibles bi- or uni-dentate ; clypeus 

 apically truncate. Antennal flagellum of $ not crenulate. Pronotum 

 often anteriorly pale, generally inferiorly striolate ; mesosternal epicnemia 

 interrupted above. Gastrocaeli and thyridii usually small, not broader 

 than the never strongly sculptured but usually smoothly punctate inter- 

 vening space ; second, third and often the fourth ventral segments plicate. 

 Tarsi setose beneath.
