Ichnea digna Wolcott, 1927: 93 . Holotype. Gender not known. San Carlos , Costa Rica, Schild and Burgdorf (USNM). (Specimen pin mounted, no other information available.) Blackwelder 1945: 389; Corporaal 1950: 270.

Diagnosis. Specimens of this species have a narrow, essentially planar frons (although in some specimens, including the holotype, there is a faint, longitudinal impression). In these characteristics, beetles of I. digna differ from superficially similar specimens of I. gremia in that the elytral disc does not show a pale transverse fascia.

Description. Size: Length 7.7 mm; width 2.6 mm. Form ( Fig. 143 View Figs ): Oblong subovoid. Integ- umental color ( Figs. 57, 58): Cranium mostly yellow, dark markings behind eye; pronotum roseate; elytra mostly dark brown, with yellow lines along sutural and epipleural margins; profemora with anterior facies yellow, remainder brown, mesofemora and metafemora mostly yellow, with dorsal brown line. Head: HW/PW 1.0; frons minutely indented; EW/VW 3.9; antenna as in Fig. 160 View Figs , funicle not compressed. Thorax: PL/PW 1.0; elytra broad subovoid, EL/PL 5.6; EL/EW 2.2; anterior margin of protibia with 12 spines. Male genitalia: Aedeagus as in Fig. 178 View Figs . Male mesodermal internal reproductive organs ( Fig. 200 View Figs ): Medial accessory gland about as long as lateral gland; testes comprised of 22 follicles.

Variation. Size: length 5.5–6.1 mm; width 1.7– 2.5 mm. The pronotum may be entirely roseate, but with anteromedial and posteromedial dark spots, or yellow at the sides and a variously expressed dark vertical vitta on the disc.

Natural History. Specimens have been collected from December through June; some in a Malaise trap in primary and secondary rainforest and some on a fallen log of P. macroloba . The known altitudes from which these beetles have been captured range from 150 to 610 m.

Distribution. The known range of this species extends from Nicaragua to western Colombia ( Map 5 View Map 5 ).
