ICHNEUMON-FLIES — GELINAE : MESOSTENINI 221 



Wings weakly infuscate; hind femur ferruginous; first segment of female 

 flagellum about 4.8 as long as wide; range: northern half of North America.

18a. Trachysphyrus luctuosus subquadratus (Thomson), new status 



Cryptus subquadratus Thomson, 1873, Opuscula entomologica, fasc. 5, p. 478; 



? . Type: ? , Esperod, SkSne, Sweden (?Lund). Type not seen. 

 Cryptus holalpinus Heinrich, 1951, Bonner Zool. Beitr., vol. 3-4, p. 281; d', ?. 



New synonymy. Type: ? , Kalbling near Admont, 1,700 m., Steiermark, 



Austria (Townes). 



Lower 0.3 of frons with more or less distinct transverse wrinlding; 

 first segment of female flagellum about 3.8 as long as wide; apical 

 carina of propodeum of male rather weak to quite strong. 



Coloration as described for the subspecies luctuosus except that 

 front and middle femora of male are often more or less blacldsh, 

 front and middle tibiae of male are sometimes somewhat infuscate, 

 pale coloration on femora and tibiae of both sexes is nearer to fulvous 

 than ferruginous, tegula and subtegular ridge of female are black 

 in the specimens at hand, segment 2 of male hind tarsus is entirely 

 white, and wings are subhyaline. 



Thomson's description of subquadratus calls for a white spot in 

 the middle of the clypeus of the female. This character seems not 

 to occur or to be abnormal for the present form, but all the rest of 

 his description agrees perfcctl3^ 



Specimens : 6 cf , 39 (all of them types of holalpinus) from Germany, 

 (Berchtesgaden) and Austria (Steiermark).
