574 Mr. Cameron’ s@@tcs on Hymenoptera, 
are shorter and stouter, the abdomen has only four of 
the segments red, the wings are fuscous, and the saw 
is different. Otherwise the coloration is the same as 
with ornatus. 
Dr. Sharp found 7’. dorsatus in Spain. 
Dolerus tinctipennis, n. 8. 
Deep black, shining, covered on head and thorax with 
a close white longish pubescence ; head roughly punc- 
tured; the scutellum and middle lobe of mesonotum 
clearly but not deeply, nor closely, the lateral lobes on 
inner sides faintly, and on outer scarcely, punctured. 
Sutures on vertex scarcely visible. Antenne not much 
longer than the abdomen, the third jomt not much 
thinner than the following, and one-fourth longer than the 
fourth, which is a very little longer than the fifth ; the 
joints from the fourth distinctly thickened, the two apical 
a very little thinner than the preceding, but still thicker 
than the third. Cenchri large, greyish white. Base of 
abdomen smooth, impunctate. Wings with deep black 
nervures and stigma; apical half in both wings fuscous, 
inner half hyaline; accessory nervure in hind wings 
shortly appendiculated. Spurs longish; four anterior 
fuscous, posterior deep black. Length 33 lin. 
The nearest ally of this species is D. Gesneri, André ; 
but that species is much larger, has the antenne longer 
and more filiform, the mesonotum more deeply and 
uniformly punctured all over, and the wings not so 
deeply fuscous in colour. The saw of tinctipennis and 
Gesnert agrees with that of D. dubius, Kl., in having 
the surface indented with cross-bars bearing teeth. See 
Hartig, Blattw., pl. v., fig. 4a. 
D. Gesneri, André, I found at Loch Awe last June. 
The front legs are sometimes entirely black. 
Dolerus megapterus, Ni. 8. 
Black ; head and thorax opaque, densely covered all 
over with a close longish grey pile, which gives these 
parts a greyish appearance; closely punctured all over. 
Antenne not much longer than the head and thorax, 
short, thick, the last joint distinctly thinner than the 
eighth, the third much longer than the fourth. Cenchri
