A. Scutellum white soliiaria, Scop. 



B. Scutellum black. 



a. The 5th joint white. 



1. Eyes and pronotum marked with wliite ; abdomen bronzy, often reddish. 



No spot over hind coxae. 



Tegulae white, pleurae more or less rufous rufiventris, Fab. 



Tegulae and pleurae black hctUeata, Kl. 



2. Eyes and pronotum not marked with wliite ; abdomen black ; a single 



spot over hind coxse velox, Fab. 



I. The 5th joint black. 



1. Stigma distinctly white at the base livida,'Li. 



2. Stigma not distinctly white at the base ; apex of abdomen red (rarely 



black), tegulae red colon, Kl. 



Middle of abdomen red ; tegulee black coryli, 'Kl. 



Except velooe, these species have been recorded from almost all 

 the European countries ; velox I can only find recorded from Germany 

 (Halle), Silesia, Holland, and Italy. In Scotland it is common, and 

 extends to Sutherlandshire ; and yet, curiously enough, it does not 

 appear to occur in Scandinavia : nor does it seem to be a common 

 English species. 



Erom the great variation in coloration which T. livida exhibits, it 

 is often a puzzling form to beginners ; yet the half white, half fuscous 

 stigma forms a slight but constant mark of distinction. The form 

 with entirely black abdomen and legs is, I believe, the T. bipunctata 

 of Klug and Hartig. 



On re-examining my specimens of Dolerus of the gonager section, 

 I found among them two species new to our Eauna, viz., D. puncticoUis, 

 Thoms. (Hymen. Scand., i, 286, 14), and D. Uogaster, Thorns. (/. c, 

 286, 15). The former is distinguished from gonager by its shorter 

 antennae, by the mesonotum being strongly punctured all over, the 

 puncturing on the head, too, being much stronger ; gonager, on the 

 other hand, having the sides of the mesonotum almost smooth. D. 

 liogaster differs from both in having the femora red, except at extreme 

 base, and the cerci all red. D. vestigialis agrees with liogaster in the 

 coloration of the femora, but the tibiae are almost entirely red, the 

 cerci black ; while the ? has, on the 2nd and 3rd abdominal segments, 

 a white puncture, and the ^ on almost all the segments ; and the eyes 

 are oblong and emarginated on the inner side. Thomson says that 

 liogaster has the thorax in front marked red, but I can discover no 

 trace of this in my specimens. Of liogaster, I have taken several spe- 

 cimens in Clydesdale by sweeping grass at the end of May and 

 beginning of June ; oi puncticoUis, I have one Scotch example without 

 a note of the precise locality ; and another specimen has been taken 

 by Mr. Bignell near Plymouth.
