Aegialia (Aegialia) carri

DESCRIPTION—Holotype: Male, length 40 mm, greatest width 20 mm Form elongate, widest behind middle Color black, leg reddish brown Head granulate, lacking punctations; clypeal apex distinctly emarginate, gena slightly produced Pronotal surface alutaceous, punctations moderately coarse, separated by a diameter or less on disc, becoming sparse on lateral third; base with marginal line Elytron with interval convex, impunctate; stria distinctly impressed, strial punctations separated by a diameter Metasternum smooth, impunctate medially, alutaceous and impunctate laterally Functional wings present Middle tibia short, strongly expanded at apex, without complete transverse carina, apical spurs long, slender, outer spur as long as first 2½ tarsal segments, inner spur as long as first 2½ tarsal segments Genitalia as in Figure 46

Allotype: Similar to male except length 460 mm, greatest width 220 mm; base of pronotum with short, longitudinal furrow medially; genital plate as in Figure 47

Variation: Length ranges from 380 to 470 mm, greatest width from 190 to 225 mm The short, median basal furrow on the pronotum is present in most specimens but absent or very feeble in some

TYPE MATERIAL—Holotype: Alberta, Calgary, 14 May 1965, BG and JL Carr, Lot 1 (USNM) Allotype: same data as holotype (JC) Paratypes: 31, same data as holotype; 54, Alberta, Calgary, 9 Apr 56, 19 Apr 56, 21 Sep 1958, 10 Apr 1960, 10 May 1960, 9 May 1962, 10 May 1962, 15 May 1963, 4 Apr 1964, 8 Apr 1964, 9 May 1964, 2 May 1965, 8 Jul 1974, BF and JL Carr; Alberta, Ghost Dam, 11 Jul 1982, 15 May 1985, BF and JL Carr; Alberta, Pincher 5 May 73, Carr; Alberta, “Tp 24 Rge 24, W 4 Mer,” 3 May 1973, BF and JL Carr (CNC, HH, JC, USNM)

REMARKS—Aegialia carri is similar to A blanchardi but differs in having the pronotal surface alutaceous and the pronotal punctations separated by a diameter or less; body more slender and average size smaller; elytral intervals more convex; apex of the middle tibia much more abruptly expanded; and the apical spurs of the hindtibia shorter

ETYMOLOGY—We name this species for John Carr who collected all of the specimens of the type series described here
