Odontomerns strangaliae Rohwer, 1917, Proc. U. S. Nat. Mus., vol. 53, p. 158, ? . 

 Type: 9, Ballston, Va. (Washington). 



Male: Front wing 3.5 to 7.2 mm. long; first flagellar segment about 

 1.12 as long as second; punctures on mesoscutum small, weak, sepa- 

 rated by about 2.5 their diameter; propodeal teeth about 1.0 as long 

 as their basal width, punctures on hind femur moderately strong, less 

 dense than usual, much sparser below the middle, near lower edge 

 of femur separated by about five times their diameter; hairs on hind 

 femur unusually long; second segment of middle tarsus about 3.4 as 

 long as deep; fifth segment of hind tarsus about 1.16 as long as second 

 segment; nervellus broken near its lower 0.38; second tergite sub- 

 polished, its basal 0.15± with rather weak wrinkling, its punctures 

 very small and weak, evenly distributed, separated by about 0.7 the 

 length of the hairs. 



Coloration as in the female except that abdomen is entirely black, 

 or sometimes with weak fulvous tinges. 



Female: Front wing 5.3 to 9.8 mm. long; flagellum with about 

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

 0.99 as wide across temples as across eyes; punctures on temple mod- 

 erately coarse, separated by about 2.5 their diameter; thorax about 2.23 

 as long as high; upper 0.3 ± of pronotum with small punctures that 

 are separated by about 3 times their diameter; trough of pronotum 

 smooth; epomia rather strong; mesoscutal punctures small, separated 

 by about 4 times their diameter; mesepimeron with hairs all over, 

 but these a little sparser below; metapleurum smooth or with more 

 or less distinct irregular wrinkling, its punctures moderate sized, sharp, 

 separated by about 1.5 their diameter; petiolar area about 0.57 as 

 long as combined areola and basal area; propodeal teeth about 0.9 

 as long as their basal width; hairs in first lateral area sparse, their 

 sockets separated by about 1.2 the length of the hairs; hind femur 

 about 2.05 as long as deep, the punctures on its upper 0.26 ± moder- 

 ately large and strong, separated by about 1.5 their diameter, the 

 lower 0.75 ± with sparse punctures that are separated by about 

 5 times their diameter; hairs on hind femur longer and averaging 

 sparser than in an}? - other species of the genus; second segment of 

 middle tarsus about 1.6 as long as deep; fifth segment of hind tarsus 

 about 1.60 as long as second segment; second tergite polished, a little 

 wrinkled at extreme base, with almost no punctures or hairs.
