Neunzig Department of Entomology, North Carolina State University, Raleigh, North Carolina 27695-7613. Abstract.— Two new genera of phycitine moths from Mexico are described. They are Nevacolima, n. gen. with N. jaliscoensis, n. sp. and A', zodia, n. sp., and Megacerdresa, n. gen. with M. cordobensis, n. sp. Also described from the Republic is Homoeographa mexicana, n. sp. Key Words: Moths, phycitines, Mexico Seventy-nine species of phycitines have been previously reported from Mexico (Ci-brian-Tovar et al. 1986, Hedlin et al. 1981, Heinrich 1956, McGufhn 1967, Mutuura and Neunzig 1986, Neunzig 1983, 1986, 1990). Based on the size of the Republic, the diversity of habitats found in the coun-try, and the abundance of phycitine species elsewhere in North America, this number obviously represents only a small fraction of the Mexican fauna of Phycitinae. While identifying phycitines on loan from the San Diego Natural History' Museum (SDNHM), and the University of California at Davis (UCD), 1 found four additional Mexican species belonging to the subfamily. All are new species, one is a Homoeographa. and the others are of particular interest be-cause they belong to previously undescribed genera. Nevacolima Neunzig, New Genus Gender. — Feminine. Type sptcifi.— Nevacolima jaliscoensis Neunzig. Antenna of male simple (Fig. 9) or with sinus at base of shaft (Fig. 8). Front convex, roughly scaled. Labial palpus oblique (Fig. 13). Maxillary palpus simple. Haustellum well developed. Ocellus present. Basal half of costa of forewing of male (Figs. 6, 7) slightly convex or slightly concave; under-side of wing of male simple, without costal fold or sex-scaling. Forewing without raised scales; with eleven veins, R: at base close to, but separate from R^j and R^; R, .4 and R5 stalked for over Vi their lengths; M, slightly curved to straight; M, and M, sep-arate, but close at base; CuA, from lower outer angle of cell; CuA, from well before lower outer angle of cell. Hindwing (Figs. 6, 7) with eight veins (lA, 2A and 3 A consid-ered together to be one vein); Sc + R, and Rs fused for about Vi their lengths beyond cell; M| from upper outer angle of cell; M, and M, stalked for about '/s their lengths; CuA, from lower outer angle of cell; CuA, from well before angle of cell; cell less than '/2 length of wing. Male abdominal segment 8 with ventral scale tufts (Figs. 1 6, 1 9); scales forming tufts pale to black, short to long, mainly straight and slender; sclerotized bar associated with tufts with rather large, swol-len, distally-rounded, medial projection or slender medial projection. Male genitalia (Figs. 14, 15, 17, 18) with uncus absent; gnathos with distal part consisting of two
