Abdomen with transversely alutaceous surface sculpture obsolescent on the 1st and middle of the 2nd tergites. Pubescence silvery all over and on the head and thorax, about 2 times longer than the diameter of the fore ocellus. Wings subhyaline with black venation. 9.0-10.0 mm. - Rare montaneous species. Known only from Turkey montivagus Benson 7 (4) One- or two-thirds of hind femur and base of hind tibia reddish-yellow. Head parallel-sided or swollen behind in dorsal aspect. Occipital furrow poorly developed 8(13) Sawsheath in dorsal aspect parallel, rounded apically, or slightly dilated. Wings well developed and only slightly infuscate (Figs 55-57) 9 (10) Apical setae of sawsheath strongly curved apically. Clypeus slightly and triangularly emarginated. Head behind the eyes parallel and roughly punctured. Pubescence greyish-white as long as the diameter of front ocellus. Mesonotum with shining interspaces. Wings hyaline slightly opalescent. Sawsheath in Fig. 57. 9.0-11.0 mm. - Very rare. Known only from the Caucasus albertii Muche 10 (9) Apical setae of sawsheath not so strongly curved apically. 11 (12) Lateral lobes of mesonotum closely and conspicuously punctured laterally. Longer lateral setae near the apex of the sawsheath (Fig. 55) are directed more outwards in dorsal aspect, so that they form with the corresponding setae on the other side of the sawsheath an obtuse angle. 4th—6th serrulae in Fig. 2. 8.0-9.0 mm. - Common species. Insect pest in Central Europe puncticollis C. G. Thomson 12 (11) Lateral lobes of mesonotum very shining laterally, with sparse and very superficial punctures. Longer lateral setae near the apex of the sawsheath directed more backwards so that they form with the corresponding setae on the other side of the sawsheath an acute angle (Fig. 56). 4th-6th serrulae in Fig. 3. 8.0-9.0 mm. - All Europe and the Caucasus. Common species. Insect pest in Central Europe gonager (Fabricius) 13 (8) Sawsheath in dorsal aspect strongly dilated (Figs 58, 89) 14 (15) Wings hyaline with black venation. Head slightly contracted behind eyes. Clypeus broadly emarginated in front to a depth of about one-third of its total length. Antenna with 8th segment about 4 times longer than its basal breadth. Punctuation coarse. Occipital furrows clearly marked. Front lobes of mesonotum punctured laterally but with the middle half shining with shallow sparse punctures; middle lobes shining with sparse shallow punctures on the front half. Pubescence silvery; on head and thorax up to about twice the diameter of ocellus. Sawsheath in Fig. 89. 8.0-9.0 mm. - Very rare. Known only from Turkey hyrcanus Benson 15 (14) Wings dark infuscate, occasionally undeveloped 16(17) Clypeus broadly and triangularly excised to a depth of one-third of its total length. Wings dark infuscate and normally developed. Head densely punctured.
