ICHNEUMON-FLIES, PART 2 : XORIDINAE 471 



Black. Clypeus, mandible, and basal part of antenna often stained 

 with ferruginous; labrum, legs, and abdomen ferruginous; palpi light 

 brown; tegula ferruginous to blackish; wings tinted with brown. 

 Often the propodeum is partly ferruginous. 



The female is recognizable by its red abdomen, sparsely punctate 

 mesoscutum and lower part of hiDd femur, and short flagellum.

14. Odontocolon sierrae, new species 



Male: Front wing 3.5 to 5.7 mm. long; first segment of flagellum 

 about 1.1 as long as second segment; punctures on mesoscutum of 

 moderate size, rather weak, separated by about 2.5 times their diam- 

 eter; propodeal teeth low, about 0.4 as high as basal width; punctures 

 on hind femur rather weak, on upper half separated by about their 

 diameter, sparser below the middle, near lower edge separated by 

 about 3 to 4 times their diameter, second segment of middle tarsus 

 about 3.3 as long as deep; fifth segment of hind tarsus about 0.85 as 

 long as second segment; second tergite polished but with fine weak 

 rugulosity basally, its punctures fine, separated by about 0.65 the 

 length of the hairs. 



Coloration as in the female. 



Female: Front wing 4.4 to 7.4 mm. long; flagellum with about 33 

 segments, its first segment about 1.35 as long as second; head about 

 1.005 as wide across temples as across eyes; punctures on temple 

 small, separated by about 3 times their diameter; thorax about 2.10 

 as long as high; upper 0.25 ± of pronotum with very fine punctures 

 that are separated by about 4 times their diameter; trough of prono- 

 tum with irregular transverse ridges in its anterior 0.6 ± , the postero- 

 ventral 0.4 ± of its length with long horizontal wrinkles; punctures 

 on mesoscutum fine, rather sharp, separated by about 3 times their 

 diameter; mesepimeron with hairs on its upper 0.7 ±; metapleurum 

 with strong, irregularly longitudinal wrinkles, not distinctly punctate; 

 petiolar area about 0.47 as long as combined areola and basal area; 

 propodeal teeth about 0.5 as long as their basal width; hairs on first 

 lateral area moderately dense, their sockets separated by about 0.9 

 the length of the hairs; hind femur about 2.17 as long as deep, with 

 fine, rather weak, close punctures all over, the punctures a little sparser
