. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology; Zoology. 490 bulletin: museum of comparative zoology. ANTHICIDAE. Lithomacratria, gen. nov. Form similar to Corphyra. Antennae, in general, of the type seen in the modern genus Macratria but more highly differentiated, the distal three joints much longer than all of the remainder, slightly in- crassate. Prothorax short, transverse, not elongate as in Macratria. Type.— L. mirabilis, sp. nov. Lithomacratria mirabilis, sp. nov. Plate 16, fig. 1-2. Form moderately stout. Head not enlarged, tempora rounded, surface nearly smooth but with a visible alutaceous sculpture. Pal- pus, probably maxillary, enlarged apically. Antennae moderately long, reaching, in life, about to the base of the elytra, joints two to eight short, subequal, not serrate, ninth and tenth each about equal to the sixth, seventh, and eighth united, eleventh more than four fifths as long as the combined ninth and tenth, these distal three joints only a little broader than the others. Prothorax about as long as the head, sculpture minute. Elytra about three and one half times as long as the prothorax, finely punctulate and moderately closely clothed with brownish hairs which do not at all conceal the surface. Abdomen alutaceous. Legs not very well preserved, fairly slender. Length, as preserved, mm.; of elytron, mm. Described from one specimen with counterpart. Type.— No. 2,694, 2,695 M. C. Z. Florissant, Col. (No. 11,257 and 13,655 S. H. Scudder Coll.). My idea is that this fossil should belong near Macratria, but the basis for this opinion rests mostly upon the type of antennal structure. The aspect is decidedly more that of Corphyra and the size also corre- sponds better with the latter genus. It seems, by description, to differ from M. giganiea in being smaller and having a different protho- rax and antennae, but the type of M. gigantea is not now at hand for Please note that these images are extrac
