no. 1812. NEW ICHNEUMON FLIES— VIERECK. 193 



side; hind tibiae whitish, brownish at base and apex; first tergal 

 segment with gradually converging sides to the beginning of the 

 apical two-thirds, beyond this point gradually widening so that it is 

 at least twice as wide at apex as at base, smooth and polished; 

 setting of the spiracles virtually not at all elevated to a higher plane 

 than the rest of the segment, postpetiole with a shallow almost tear- 

 shaped fossa down the middle, second tergal segment with a deeply, 

 triangularly emarginate black band immediately beyond the thyridia. 



Type.— Cat. No. 13509, U.S.N.M. 



Type-locality. — Grand River, Iowa. 



Presumably parasitic on Microplitis melianse Viereck. *From 

 Meliana albilinea, Experiment 500, July, 1910." R. L. Webster. 



PHYGADEUON (BATHYMETIS) PATULUS, new species. 



Male. — Length, 7.5 mm. Compared with the description of 

 Phygadeuon (Mastrus) neodiprioni Viereck as given below this 

 species differs as follows: Face shining, with rather clearly defined 

 punctures, clypeus with a testaceous mark on each side, antennas 

 30-jointed, flagel brownish throughout, darker above on basal half 

 and throughout beyond the middle than above at base; tegulae 

 yellow, coxae and trochanters of fore legs and trochanters of middle 

 legs mostly yellow, fore tibiae and tarsi virtually stramineous, middle 

 lateral area ribbed with rather prominent rugae; tergum smooth, 

 polished, almost sculptureless throughout. 



Type.— Cat. No. 13506, U.S.N.M. 



Type-locality. — Crawford , Nebraska.

Genus DAICTES Foerster (= ISOTIMA Foerster.) 



The following species is regarded by the writer as an Isotima with 

 an areolet, as is found in Ilemiteles Gravenhorst, strictly speaking. 

 As it agrees with the diagnosis of Daictes Foerster except in having 

 an incomplete areolet and the latter name has page precedence, it is 

 proposed to regard it as a Daictes Foerster and assign it as a sub- 

 genus of Phygadeuon at present, it being apparently a Phygadeuo- 

 nine in spite of the conformation of the areolet. Compared with the 

 genotype of Stiboscopus (Foerster) Ashmead, Stiboscopus thoracicus 

 Ashmead, the description of Daictes will read as follows: 



Antennae thickened so that the first flagellar joint is hardly more 

 than three times as long as thick at base, greatest width of head 

 back of the eyes, as seen in profile as great as the corresponding width 

 of the eyes seen from the same point of view, distance from the 

 antennal line to the apex of clypeus about as great as the distance 

 from middle of face to eye margin; apical transverse carina
