Head and thorax with silvery pubescence 43 (44) Sawsheath extraordinarily dilated apically, the width here being about the same as the apical width of the hind tibia; each side of apex of sawsheath with long curved setae (Fig. 82). 4th-6th serrulae in Fig. 27. 8.0-9.0 mm. - Frequent European species picipes Klug 44 (43) Sawsheath in dorsal aspect not extremely or only slightly dilated apically, the width here being less than three-quarters of the hind tibia (Figs 83-84, 86). 45 (46) Sawsheath with the long setae almost straight (Fig. 83), 4th-6th serrulae in Fig. 28. 9.0-10.5 mm. - Common European species. Insect pest on cereal and grass cultures nigratus (O. F. Müller) 46 (45) Apical setae of sawsheath slightly curved apically (Figs 84-86). 47 (48) Longer setae of sawsheath sligthly curved (Fig. 84). 4th-6th serrulae in Fig. 29. 9.0-10.5 mm. - Sporadic species. Korea and Kamchatka novograblenovi Malaise 48 (47) Sawsheath with the long setae on each side longer and more curved apically (Fig. 86). 4th—6th serrulae in Fig. 30. 8.0-9.0 mm varispinus Hartig Table D 1 (6) Body entirely black, or dominantly black with brownish yellow spots 2 (3) Robust black species. Mouthparts, mesonotum, mesopleuron, pronotum more or less coloured with brownish yellow spots. Labrum, basis of mandibel, clypeus, all tibiae, lower two-thirds of the first two femora, the lower third of hind femur, tegulae, sawsheath dorsally yellowish-brown. Sometimes the mouthparts almost entirely black. The other parts of the body black. Clypeus deeply emarginated. Third antennái joint much longer than the fourth. Head behind eyes slightly converging, densely and deeply punctured as is the mesonotum. Mesopleuron roughly and densely punctured. Pubescence short and whitish. Wings hyaline. Sawsheath in Fig. 88. 10.0-12.0 mm. - Sporadic. Known only from Kamchatka, Russia variator Enslin 3 (2) Entirely black insects, only legs may be coloured with red. 4 (5) Entirely black species, including legs, with the middle of the fore and lateral lobes of the mesonotum as well as the middle of the scutellum covered with a large shining area being impunctate or feebly punctate. Sawsheath in Fig. 96. 8.0-9.5 mm. - Rare European species pachycerus Hartig 5 (4) Larger (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. (Dolerus yukonensis Norton may also has black colour variation, check couplet 15 (16).) 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.
