Length 12.3-14.3 mm. Width 4.7-5.3 mm. Holotype, cf: Kuban district, Nakhar pass, 23.VII. 1911, leg. N. BRYANSKIJ (ZIL). Paratypes: the same locality, 14 ex.; slope of Bu-ulgen Mt., 8.IX. 1909, 1 ex.; Cauc. centr. bor., Kluchor pass, 8000 ft, leg. A. ZOLOTAREW, 2 ex.; southern slope of Klukhor pass, 2 ex.; road to the Klukhor pass, 1 ex.; Klukhor pass, 3.VIII. 1909, 1 ex.; Tersk district, vicinity of Elbrus, Begasyn Mt., 14.VIII. 1911, leg. N. BRYANSKIJ, 1 ex.; southern slope of Dongus-orun pass, 19.VIII.

1911, leg. N. BRYANSKIJ, 4 ex.; eastern slope of Elbrus Mt.

, glacier Azaj, 6. VIII. 1911, leg. N. BRYANSKIJ, 1 ex.; glacier in the source of Kuban river, Ulukam-Karas und Ulu-ozen, 1 ex.; Swanetia, Bassa pass, Chebukhevi, 2 ex.; Swanetia, valley of Yusenga river, northern slope of Bego pass, 14.VII. 1948, leg. V. KURNAKOV, 8 ex. (all paratypes in ZIL, some paratipes in ISU, HNHM). Outwardly closely related to N. commixta Chaud., but larger and narrower, pronotum 1.251.35 times as wide as long (in N. commixta 1.37-1, 58), basal area and lateral sides of pronotum punctate evidently fainter, segment 4 of hind tarsi much more extending from below. But the main difference is in the chetotaxy of mentum, which bears 4-6 setae on the base. It is the unique sign around the Caucasian Nebria

, all of them have only constant 2 setae on the base of mentum. Nebria (Alpaeus) patruelis Chaud. Nebria patruelis Chaudoir, 1846: 111 (type locality: "montagne qui domine Glola, en Imérétie") Nebria patruelis

, Kirshenblat, 1932: 94 Black, shiny, head with two oblique red frontal spots, which often confluent with each other, legs and antennae black or legs entirely red, antennae somewhat paler from segment 5. Pronotum (fig. 117) at sides rather strongly sinuated before rectangular or acute hind angles. First antennái segment (fig. 107) smaller than in N. motschulskyi Chaud., aedeagus (Figs 135-138, 145, 146) thinner, with shorter apical lamella, paramerae (Figs 147, 148, 151, 152) narrower. Base of hind coxae unisetose, sternits 3-5 with proportion of setae 2+2, 2+3, 3+3, rare 1+2, 1+1. Anal sternit in male with 2, in female with 4 setae on hind margin. Length 11.0-13.3 mm. Width 3.9-4.9 mm. Material.

(ZIL). "Kaukasus, Swanetien, LEDER, REITTER" (HNHM, MB). "Swanetia, 1889, C. ROST"; "Elbrus, 1890, C. ROST" (MB). The relationship between N. patruelis Chaud, and N. motschulskyi Chaud, has for long time been unclear. BANNINGER (1925) had not known N. motschulskyi and supposed that it was closely related to N. patruelis

. Then CSIKI (1927) considered N. motschulskyi as a variation of N. patruelis

. KIRSHENBLAT (1932) rehabilitated N. motschulskyi to specific rank, but his identification of this species was doubtful. I have received types of both species from the collection of CHAUDOIR (MP), moreover new material of N. motschulskyi was found, which allows more precise definition of its distribution.
