Dorsal side (Fig. 6): Clypeal hairs originating along a common transverse line, inner pair of hairs slightly longer than outer one. Hairs d^, e^, and f^ of segments D-F about equalin length, hair e

2 slightly longer than hair f

, but also the latter one only half as long as inner ones. Hairs o£ segment H very characteristic: h^ and h^ very long, thin, densely ciliate, h^ minute, smooth. "Ventral side (Fig. 7): Anterior sternal plate considerably narrower than posterior one. Apodemes of both plates weakly developed. Hairs la, lb, and 2a densely ciliate, nearly peniciUate, hair 2b incrassate, spiniform. Majority of hairs originating on posterior sternal plate short, hairs 3a and 3c arising on a common line, 3b behind these. Hairs 4a originating far anterior to hairs 4b; these latter not approaching posterior margin of body. Legs: All legs strikingly thickened, wide, short, hence legs rather stout. Tibiotarsus of leg I (Fig. 8) with short hairs d and dT, the latter ones being longer than former ones. No essential difference in length between solenidia cp p cJ ^ and CJ

2

. Hairs of legs II and III (Fig. 10) also short, hair Idj' of tarsus heavily incrassate, ciliate. Tarsus of leg IV (Fig. 9) with 6 hairs, setae dT and ld-^' approximately equal in length. Material examined: Holotype (123-HT-76): Missouri, St. Charles Co., Orchard Farm. 28 June, 1973. On Geomys bursarius. Leg. E.J. SPICKA. Deposieted in the HNHM. Remarks The new species is closely related to Scutacarus longisetus Berlese, 1903. However, in the known congeners, haris 4a - 4b arise along a common line, and hairs d^, e^, and f^ are of divers lengths. Scutacarus geomyi sp. n. Measurements: Length 235 ju, width 225 p. Habitus: Wide, nearly circular in shape, clypeus hardly wider than other body segments. Dorsal side (Fig, 11): Inner clypeal hairs thicker than outer ones, obtuse, aciculiform, outer ones filiform, attenuate, arising anterior to inner ones. Inner hairs of segments D-F straight, rigid, also relatively obtuse, hair e-^ longer than d^ and f^, hairs e

2

and f

2 hardly shorter than e^, their form similar to that of hair c

2

. Hairs h^ and h

2 of segment H originating nearly adjacent, equal in length, hair 113 similar in shape though slightly thinner and more removed. Ventral side (Fig. 12): Both anterior and posterior sternal plates heavily sclerotized. Anterior angles of posterior plate projecting, quadrangular. Also apodemes well developed, even ap. sec. thick. Except for hair 2^, all hairs of anterior sternal plate densely and penicillately ciliate, especially nair la. Hairs 4b of posterior sternal plate originating anterior to hairs 4a, their basal half sparsely, their distal half gradually more densely ciliate. Legs: Tibiotarsus of leg I (Fig. 13) with long hairs d, dT, and solenidia; " CJ ^ and es 2 about equal in length, u ^ considerably thicker. Tarsus of legs II and III (Fig. 14) with hair ldj incrassate, spiniform, and also ciliate. Tibiotarsus of leg IV (Fig. 15) much elongated, about thrice longer than wide; distal end of inner side of femur projecting into a robust, triangular apex. Material examined: Holotype (124-HT-76): Illinois, Woodford Co. , Minouk 10 May, 1973. On Geomys bursarius. Leg. E.J. SPICKA. Deposited in the HNHM. Remarks The new species belongs to the alliance of Scutacarus sphaeroideus Karafiat, 1959. Of this group of species only S. wranoskyi Mahunka, 1970 has been known from the USA. From this
