ICHNEUMON-FLIES — GELINAE : MESOSTENINI 209 



Calescens group also have pits on the frons, but in these the axillus 

 vein is divergent from the wing margin, rather than convergent. 



13. Trachysphyrus laborator (Thiinberg) 



Front wing 6.0 to 12.5 mm. long; body rather slender; lower half 

 of frons with rather fine wrinkling, in the female the wrinlding usually 

 with a vertical bias; pits on frons moderately deep; first segment of 

 female flagellum about 8 times as long as wide ; temple weakly to rather 

 strongl^^ convex; mesopleurum with dense reticulate wrinkling which 

 appears to have resulted from the crowding of punctures ; hind femur 

 of male about 6.0 as long as deep, of female about 5.8 as long as deep. 



There are five subspecies, differing mostly in color and in the male 

 clasper as keyed and described below: 



1. Coxae fulvous; range: most of Washington, Oregon, and California and part of 



Idaho, and Southern British Columbia . 13d. laborator perplexus (Cresson) 

 Coxae black 2 



2. Hind femur fuscous; range: Korea. . . 13b. laborator satoi, new subspecies 

 Hind femur fulvous 3 



3. Temple about 1.0 as long as eye; sculpture of pleura and propodeum very fine 



and dense; range: Greenland 13e. laborator fabricii (Schi0dte) 



Temple about 0.75 to 0.95 as long as eye; sculpture of pleura and propodeum 

 moderately fine and dense 4 



4. Apex of male clasper rounded; upper edge of male clasper without a ridgelike 



thickening; range: Europe 13a. laborator laborator (Thunberg) 



Apex of male clasper obliquely truncate; upper edge of male clasper with a 

 polished thickened ridge on its outer side; range: northern North America 

 except Greenland and the Pacific Coast area. 



13c. laborator altonii (Dalla Torre) 



13a. Trachysphyrus laborator laborator (Thunberg) 



Ichneumon laborator Thunberg, 1822, Mem. Acad. Imp. Sci. St. Petersbourg, 

 vol. 8, p. 273; 1824, vol. 9, p. 344; [cf]. Type: cf, Sweden (Uppsala). 

 Type not seen. 



Similar to the Nearctic subspecies altonii except that the temple 

 averages a little more convex, clypeus lacks the central yellow area, 

 hind tibia and tarsus are a trifle darker with the hind tarsus less 

 extensively pale in the middle, wings are subhyaline in both sexes, 

 apex of male clasper is rather narrow and obliquely rounded, and 

 dorsal edge of clasper is without a distinct ridge on the upper side. 



Specimens: 15 0^, 189, from Sweden, Netherlands, Germany, and 

 Italy. 



13b. Trachysphyrus laborator satoi, new subspecies 



Male: Unknown. 



Female type: Front wing 12.5 mm. long. Structure as in the 

 subspecies laborator and altonii.
