MTOPIIATXUS. POLYSPHINCIA. 205 



formation of the basal segment, which is but vaguely described. 

 In Ashmead's arrangement (Proc. TJ. S. Nat. Mus. 1900), this 

 genus is said by its author to come in near Trevoria, in fact 

 there is nothing in Cameron's description, given above, to exclude 

 it therefrom, except that he places it in the PIMPLINI, and Trevoria 

 is considered by Ashmead to belong to the LISSONOTINI. It' one 

 admits ICHNEUMONID^; with the areolet pentagonal into the 

 PIMPLINJE, it becomes in a very great many instances extremely 

 difficult to draw the line between that subfamily and the CRYPTIN.E, 

 since the only remaining character of value must be sought in the 

 sessility of the abdomen, a feature of such infinitely minute and 

 numerous modifications in various genera as to be simply be- 

 wildering. I allow Miopliatnus to remain here, however, since 

 the basal segment appears to be unusually sessile and, in its case, 

 no doubt seems possible respecting its location.

Miophatnus nigromaculatus, Cameron, Tijcls. Ent. 1907, p. 105 (d"). 



A pale sulphur-yellow species, with black markings. Head 

 with the apices of the basally distinctly punctate mandibles, centre 

 of frons and occiput broadly and continuously, black ; face dis- 

 tinctly punctate. Antennae, except the underside of scape, black. 

 Thorax with the closely and somewhat strongly punctate mesonotum 

 basally and laterally, and an irregular band on the centre of meta- 

 notum, broadly black ; the latter with elongate and infuscate 

 pilosity, the striations stout, centrally sinuate and becoming 

 laterally reticulate ; propleura? smooth, mesopleurae irregularly 

 punctate below and obsoletely aciculate centrally, metapleurae 

 strongly but not closely punctate. Scutellum somewhat sparsely 

 punctate, apically with the postscutellum entirely black. Abdomen 

 with the base of all the segments, more than the basal half of the 

 three first, black ; second and third segments closely but not 

 strongly punctate. Legs fulvous and paler basally, with the apices 

 of the hind coxae broadly and irregularly black, as are also the 

 posterior tarsi. Winc/s hyaline, with the stigma and nervures 

 blackish. 



Length 13 millim.
