related to its blue congeners and mimicry of white models (see JOHNSON 1986) should be investigated. Etymology - An arbitrary euphonious combination referring to the "Calico"-like grey patterns of the venter. "gamma" new species group Hitherto, Ministrymon gamma (H. H. DRUCE, 1909), new combination, a central Argentine species, has been an "isolated taxon" (sensu DRAUDT 1919) of uncertain intrageneric affinity. Its venter shows a white, grey, and tan "smear" pattern reminscent of bird droppings. SALAZAR & JOHNSON (1997) have recently documented ventral protective colouration patterns resembling bird droppings on certain Eumaeini which, along with pronophiline Satyrini (Nymphalidae), perch of bird excrement. The new species described below resembles M. gamma both in the character of its DFW brand and the VHW white, tan and brown ruptive pattern (the shades of which are, among Ministrymon, reminiscent only of M. gamma). In the genitalia the two species are also similar, males showing a greatly distended valval base with widely sclerotized lateral rims. Ministrymon cryptus n. sp. (Figs 16, 25) Diagnosis - Wings. Dorsum completely brown, FW outer angle sharp. VHW with readily recognized cryptic pattern of brown, white and black patches in which a large medial brown patch (framed by dark brown and black remnants of the postbasal and medial bands typical of Ministrymon) vividly contrasts a white basal patch and distal white and tan suffusions. Morphology. Male genitalia with extremely prominent, asymmetrical saccus, length just slightly less than valvae; valvae with elongate, narrowly tapering caudal extensions terminating bilobes distended greatly along the base with prominent lateral rims; aedeagus extremely elongate and undulate. Description - Male (Fig. 16). Tails missing on known specimen but likely tailed as typical of genus. Dorsum completely brown, discal area covered with extensive suffusive blue-hued black, FW brand apparent beneath this patch when rubbed, FW with outer angle very sharp with outer margin very straight. VFW ground smoky tan from base to well-marked blackish brown postmedial band extending from costa to cell CuA2, distad of this band ground lighter whitish tan toward costa, darker smoky tan beneath. VHW with prominent suffusive brown patch extending across entire wing between postbasal and medial area framed by variously obsolescent postbasal and medial bands; postbasal band blackish, narrow and undulate, outstanding only because of a bright whitish tan ground colour patch immediately basad, medial band comprised of blackish brown elements, obsolescent costad, more bandlike toward anal angle, latter elements blackish brown centrad, white distad and black basad and angled in a slight "W" near anal angle. Base of wing with prominent whitish tan patch, rather triangulate in shape; distad of banded central brown patch ground colour light tan to whitish tan closer to costa, darker suffusive tan toward toward anal angle, latter with
