ICHNEUMON-FLIES — gelinae: mesostenini 409 



punctures on second tergite coarse, separated by about 0.6 ± their 

 diameter; ovipositor tip as in figure 329,i. 



This species is transcontinental in the Canadian, Transition, and 

 Upper Austral zones. It is divisible into three subspecies that are 

 distinguishable on color, as keyed and described below. 



1. Mesoscutum entirely black; hind femur ferruginous with its apex usually 



black; range: United States and Canada except for California and Arizona. 



la. paludata paludata (Cresson) 



Mesoscutum largely or entirely ferruginous; hind femur entirely ferruginous, 



its apex not black 2 



2. Temple ferruginous to fuscous, not marked with ivory; range: California. 



lb. paludata californica, new subspecies 

 Temple ferruginous, ivory next to eye; range: southern Arizona. 



Ic. paludata ocularis, new subspecies 



la. Listrognathus (Fenestula) paludata paludata (Cresson)

Male: Black, the thorax and abdomen often more or less fulvous. 

 Face, frontal orbit, more or less of frontal horn, clypeus, cheek, mouth 

 parts, under half of scape, more or less of propleurum, stripe on lower 

 edge of pronotum, wider stripe on upper edge of pronotum, tegula, 

 subtegular ridge, spot of variable size on lower part of mesopleurum, 

 spot on scutellum, sometimes mesosternum next to stcrnaulus, broad 

 vertical stripe of variable size beneath propodeal apophysis, front and 

 middle coxae and trochanters, sometimes apical ventral mark on hind 

 coxa, and second through fourth segments of hind tarsus, ivory white, 

 the bases of front and middle coxae and their second trochanters 

 often tinged with fulvous; flagellum fulvous beneath; front and middle 

 tibiae and tarsi pale fulvous, their tarsi white with the fifth segments 

 brown; hind coxa, trochanters, and femur fulvous, the apex of femur 

 black; hind tibia fulvous, its basal 0.1 ± and apical 0.4it fuscous; 

 first and last segments of hind tarsus black, the rest white; ground 

 color of thorax and abdomen varying from entirely black to largely 

 fulvous, the ground color of pronotum, mesonotum, and tergites 

 beyond the fourth being always black. 



Female: Black, the thorax and abdomen often more or less fulvous. 

 Stripe on frontal orbit, sometimes facial orbit, rarely short stripe on 

 hind orbit ventrally, often the apex of frontal horn, rarely most of 

 clypeus, rarely most of mouth parts, band occupying about 4.5 seg- 

 ments of flagellum (but incomplete below), stripe on upper edge of 

 pronotum, tegula, usually subtegular ridge, usually a spot on scutel- 

 lum, sometimes a blotch on lower part of mesopleurum, often a stripe
