NO. 2181. NEW TERTIARY INSECTS— COCKERELL. 383 



Emphytus); end of subcostal cell (media of MacGillivray) produced, 

 its face on radial longer than that on discoidal, that on cubital very- 

 short (style of Macwpkya); cubital very long, receiving second re- 

 current nervure well before its middle (approach to condition of 

 MacropTiya) . 



In the tables by MacGilUvray, Eohwer, etc., this runs positively to 

 Selandriinae, and on account of the form of the body falls in the divi- 

 sion Strongylogasterini (Strongylogasterinae of Ashmead). On the 

 other hand, many details of the venation are Hke those of MacropTiya, 

 to which the insect runs in Cresson's table, except as to the character 

 of the hind legs. The genus, therefore, seems to combine the charac- 

 ters of the Selandriinae and Tenthredininae, and to lend support to 

 Ashmead's opinion that the Strongylogasterinae should be associated 

 with the latter rather than with the true Selandi'iines. 



Type of the genus. — Taeniuntes fortis, new species. 



TAENIURITES FORTIS. new spedes. 



Plate 31, fig. 14. 



Length, 14 mm,; anterior wing, 11 mm.; antennae, about 6 mm.; 

 width of abdomen, 3.7 mm.; head and thorax black; abdomen ap- 

 parently reddish, infuscated apically; wings hyahne. The follow- 

 ing measurements are in microns: Anterior wings: First marginal 

 cell on third submarginal, 1,056; second marginal on third submar- 

 ginal, 336; basal nervure on first discoidal, 864; end of basal to 

 beginning of cubital, 849; first submarginal on first discoidal, 800; 

 second submarginal on first discoidal, 704; second submarginal on 

 third discoidal, 1 ,040 ; third submarginal on third discoidal, 544 ; lower 

 side of third submarginal beyond second recurrent nervure, 1,136; 

 second discoidal on first, 1,616, and on third, 800. Hind wing : Cubital 

 cell on discoidal, 880; lower side of cubital beyond discoidal, 1,170. 



Florissant, Miocene shales. 



Type.— Csit. No. 62542, U.S.N.M. 



Among all the fossil sawflies from Florissant, this closely resembles 

 only Macropliya pervetusta Brues, from which it is distinguished by 

 the parallel-sided (not at all oval) abdomen and the form of the lanceo- 

 late cell. 



HERIADES PRISCUS, new species (MegachUidae). 



Female. — Robust, hairy, black, about 11.5 mm. long; anterior 

 wing, 6 mm. or a Httle over; wings, hyaUne; scape rather short, 

 probably about 850 microns; flagellum thick, 240 microns broad near 

 middle. Stigma well developed; two submarginal cells; second 

 (morphologically third) transversocubital nervure with a double 

 curve, its lower part strongly bulging outward; distance from end of 

 second recurrent nervure to lower end of second transversocubital
