No. 12.— Descriptions of new Neuropteroid Insects. By Nathan Banks. The continued study of the Hagen collection, together with recent accessions, particularly from Mr. C. F. Baker from the Philippines and from Mr. H. O. Parish from South America, has resulted in the recognition of various new species. This article contains the descrip-tions of many of these forms. EMBIIDAE. Oligotoma califorxica (Banks). This was described from an immature male in the genus Embia, mature examples show it to belong to Oligotoma. Recently Mr. S. B. Freeborn and others have collected numerous specimens of female Embias from California; these are much spotted as is the case with females of certain old-world species. These forms (Plate 1, fig. 11) are doubtless the previously unknown females of 0. calif ornica. Oligotoma inaequalis, sp. no v. Type.— M. C. Z. 14,878. St. Croix. (C. E. Wilson). Brown, head in front of eyes more yfellowish, femora and tibiae, except at joints, nearly black. Head hardly narrowed behind, as long behind eyes as width of head at antennae; pronotum plainly longer than broad, barely wider behind. Wings grey-brown, with five pale lines, one, broken, between radius and radial sector, several cross-veins between radius and radial sector, the first at fork of radial sector, none behind. The genitaha are similar to 0. insularis, but the second joint of the left cercus is much longer than this joint in the right cercus. Length of body 7.5 mm. ; fore wing 6 mm. Larger and darker than 0. cubcnia, and with an extra pale line in wing. Oligotoma venosa, sp. nov. Type.— M. C. Z. 14,879. Cuba: Santa Clara. (C. F. Baker). Black, head back of eyes rather yellowish, wings brown, with four white lines. Head back of eyes about as long as width of head at antennae, but
