of the mesonotal lobes. On the lateral lobes of the mesonotum, the punctures are small, more evenly spread and separated from each other 15 (16) Smaller species (6.5-8.0 mm) with entirely hyaline wings. Abdomen with shining areas on the tergites between the patches of the fine surface sculpture and without definite punctures on the 1st and 2nd tergites. Sawsheath with lateral setae finer and definitely curved, and in lateral view the sheath is acutely angled apically (Fig. 94). 4th-6th serrulae in Fig. 32. - Sporadic. N. Europe, Siberia, Mongolia and N. America yukonensis Norton 16(15) Larger species (9.0-12.5 mm) with wings slightly infuscate apically. Abdomen densely and transversely striate with definite coarse punctures on the 1st and 2nd tergites. Sawsheath with lateral setae stiff and almost straight 17 (18) Larger (10.5-12.5 mm). Very variable in colour, normally red-girdled, but if the abdomen is entirely black then the legs are also. Setae on sides of sawsheath straight, and set more outwards so that those on one side form almost a right angle with those on the other (Fig. 95). 4th-6th serrulae in Fig. 34. - Sporadic. Europe, Siberia and also found in the mountains of E. Africa pratensis (Linné) 18 (17) Smaller (9.0-10.0 mm). Normally entirely black except for the red front and middle knees. In some specimens, however, the abdomen is more or less girdled with red. Setae on sides of sawsheath very slightly curved and set more backwards, so that the longer ones on one side form an acute angle with those of the other (as in Fig. 94). 4th-6th serrulae in Fig. 33. - Sporadic. Europe, Siberia, Mongolia and N. America gessneri Ed. André Table E 1 (8) Body mainly black, occasionally the tegulae and the legs coloured with red or yellowish brown. Abdomen entirely black, or the middle segments with reddish-brown shadow, rarely the second abdominal segment red 2 (3) Larger species, 9.5-11.0 mm. Whole body black. Tibiae and apical fifth of femora red. Head black, the apical part of mandibles reddish-brown. Head behind the eyes parallel, densely and coarsely punctured. Clypeus slightly emarginated. Mesonotum densely punctured, shining. Wings hyaline, nervures and stigma black. Sawsheath in Fig. 98, 4th-6th serrulae in Fig. 36. - Sporadic. Temperate and boreal regions of E. Asia and N. America subfasciatus Smith 3 (2) Smaller species, 7.0-8.5 mm 4(5) Body and legs entirely black. Sawsheath in Fig. 103. - Rare. Austria, Switzerland laevigatus Hellén 5 (4) At least, the legs are coloured with yellowish brown or red 6 (7) Body entirely black but labrum, tegulae and apex of sawsheath brownish. Legs black with four anterior knees and anterior tibiae yellovish-brown. Head behind the eyes parallel. Clypeus deeply emarginated. Mesonotum poorly shining and reticulate, the punctures on middle of fore and of lateral lobes sparser
