and separated by about 2.5 their diameter; clypeus very weakly con- 

 vex, the impression near its apical margin not as strong as in most other 

 members of the genus; upper end of prepectal carina curved forward 

 almost to reach front edge of mesopleurum, its upper end near mid- 

 height of hind margin of pronotum; median longitudinal carinae of 

 propodeum represented by rather strong, blunt ridges which extend 

 about 0.6 the length of propodeum and are almost parallel except near 

 their apex, where they diverge more strongly; propodeal punctures 

 rather weak and rather large, separated by about 0.7 their diameter; 

 hind femur about 4.6 as long as deep, its front face with numerous 

 small, weak punctures that are separated by about twice their di- 

 ameter; bristlelike hairs on middle tibia small and weak; first tergite 

 about 1.6 as long as wide; second tergite about 1.2 as long as wide; 

 third tergite with moderately strong tubercles, the area surrounding 

 the tubercles with rather strong fine wrinkles, on the tubercles and 

 subapically with moderate-sized, rather weak punctures; ovipositor 

 sheath about 2.7 as long as front wing; lower valve of ovipositor finely 

 roughened laterally and with a row of small, irregularly spaced 

 tubercles the average distance between which is equal to about 2.5 

 the depth of the ovipositor (lower valve of ovipositor smooth in all 

 other species of the genus). 



Black. Clypeus dusky ferruginous; maxillary palpus, tegula, and 

 hind corner of pronotum white; labial palpus dark brown; front and 

 middle legs fulvous, the second trochanters, apex of first trochanters, 

 extreme apex of femora, and upper side of tibiae pale fulvous or 

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

 infuscate; hind tibia and tarsus fuscous, the basal 0.1 ± light brown; 

 wings with a faint brownish tinge. 



This is the only species of Dolickomitus in which the lower valve 

 of the ovipositor is roughened and tuberculate. Other distinctive 

 features are the long ovipositor sheath (2.7 ± as long as front wing), 

 largely fulvous hind femur, and rather strongly aciculate tergites. 

 The male is described from one of the series reared and described and 

 figured by Noskiewicz and Chuboda (1951, Polskie Pismo Ento- 

 mologiczne, vol. 21, p. 43).

This is a scarce species of the Canadian zone. It occurs in Europe, 

 where it is also scarce. The only host record is from a cerambycid 

 in Larix.
