Basis capituii width greater than length. Cornua short and apically rounded. Por- ose areas bean-shaped. Scutum: Large punctatioiis predominate in numbers over small punctations. Punctations extend beyond the posterior margin of the scu- tum. Scutum extends half the distance of the idiosoma. Cervical gr(M)ves narrow and pit-like anteriorly. Posterior margin of scutum sharply arcuate. Coxae: Coxa I witii opposing margins of in- ternal and external s|>urs parallel. External spurs present on c-oxae II, III, and 1\\ with width. Fig. 30. Dorsal and ventral views, female Dcrmacentor variabilis. equal to length. Internal spurs present, margin- al, blunt, and apically rounded on coxae II and III, absent on coxa I\'. Spiracular plate: Large and sub-circular. Coblet cells numerous, minute and uniform size. Macula oval and large. Dorsal prolonga- tion distinct and elongate. Nymph (Figure 31) Body: Idiosoma ovulate posterior, anteriorlv elongate and tapering. Length: Maximum, ; minimum, ; mean, Width: , ; minimum, ; mean 0,94. Capitulum: Width equal to length. Palps Icmg and slender. Anterolateral margin of basis capituii straight to weakly concave. Lateral points of basis long and slender, extending well.
