Pycnocryptus exactly agrees in the areolet, and the hind wing agrees, but the b. n. is straight. Coleocentrus gurnetensis, sp. n. (Fig. 3.) Thorax black. Anterior wing about 10*5 mm., marginal cell 4 mm. long; wing hyaline, with broad pale ferruginous clouds along veins and in apical part of marginal cell (as preserved) ; stigma and nervures piceous ; areolet very small, triangular, petfolate above ; stigma long and narrow; b. n. straight, going basad of the oblique Fig. Coleocentrus gurnetensis, sp. n. , In. 17079 (A'"C. Sm.). The venation agrees very well with that of the much larger C. exdtator, Poda; the size of the fossil nearly agrees with C. caligatus, Grav. At first I thought this might be a Campoplex, but the marginal cell aiid small areolet agree better with Coleoceiitms. There is some resemblance to Rhyssa, but that has r. 2 con- spicuously arched. Lithapechtis {gen. nov.) fumosus, sp. n. (Fig. 4.) Anterior wing slightly over 6*5 mm. long, fuliginous, with fuscous nervures and ferruginous stigma. Stigma well developed ; marginal cell deep, trigonal, the lower sides straight, with a strong angle at ; areolet oblique, elon- gate, the apical side smallest; b. n. arched, going basad of ; disc. 3 with upper and lower sides practically parallel except basally. H. 506, collected in 1891. Apechtis (, A. conguisitor,.
