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

 moderately small, separated by about 2.0 their diameter; thorax 

 about 2.22 as long as high; upper 0.3 ± of pronotum with moderate- 

 sized, rather weak punctures that are separated by about 2.0 their 

 diameter; trough of pronotum with some irregularly transverse strong 

 wrinkles anteriorly, elsewhere smooth; punctures on mesoscutum 

 small, weak, separated by about 4 times their diameter; hairs on 

 mesepimeron usually on its entire length but sparser below, some- 

 times absent from its lower 0.2 ± ; metapleurum with moderate-sized, 

 very weak punctures that are obscured by weak, irregular wrinkling; 

 petiolar area about 0.75 as long as combined areola and basal area; 

 propodeal teeth about 0.9 as long as their basal width; hairs in first 

 lateral area moderately dense to rather sparse; hind femur about 

 1.97 as long as deep, the punctures on its upper half fine, rather dense, 

 those on its lower half a little coarser and much sparser, separated 

 usually by about 4.0 their diameter but their density unusually 

 variable; hairs on hind femur longer than usual; second segment of 

 middle tarsus about 1.2 as long as deep; fifth segment of hind tarsus 

 about 1.9 as long as second segment; second tergite subpolished, 

 smooth except that basal 0.15± is somewhat rugulose and striate, its 

 punctures very small and scattered, separated by about 3 times the 

 length of the hairs; ovipositor sheath about 1.38 as long as front wing. 



Black. Palpi and legs pale fulvous, the tarsi somewhat brownish; 

 tegula light brown; wings subhyaline. 



This species is distinguished by its black abdomen, pale fulvous 

 legs, short flagellar segments and middle tarsus, and long fifth seg- 

 ment of hind tarsus. The temples are somewhat flaring. 



Say's type of Anomalon mellipes is destroyed and his descriptions 

 will fit the present species, ochropus, albotibiale, and vicinum about 

 equally well. Cushman (1930, Proc. U. S. Nat. Mus., vol. 77, art. 

 3, p. 10) has restricted the name to the present species, and we follow 

 his lead as first reviser.
