The flagellum is black, with the tip of the apical segment reddish, 

 the segments increasing in diameter outward to the tenth, thence 

 slightly decreasing to the apex. The wings are hyaline. The 

 pubescence is short and inconspicuous. The apical tergite bears a 

 median carina and is closely and finely punctate, the punctures be- 

 coming coarser toward the apex, where a slight tendency to rugosity 

 becomes evident. The sixth sternite is finely punctulate with widely 

 separated coarser punctures scattered over the surface. 



Described from a single female from Santa Isabel, Rio Negro, 

 Uruguay, collected by J. D. Haseman.

SELMAN, new genus 



Figures 17, 18 



Genotype. — Selman angmtus. new species. 



The characters that distinguish this genus from the genus Stictia^ 

 to which it is closely related, are the following: ocelli functional (at 

 least not reduced to cicatrices) ; middle of vertex elevated instead of 

 being depressed; body slender instead of stout and robust. 



Head wide as thorax ; eyes naked ; ocelli provided with true lenses 

 (not reduced to cicatrices) ; anterior ocellus circular in shape, but 

 only slightly greater than a semicircle in extent ; middle of vertex on 

 a level with the top of the eyes; inner eye-margins parallel; slight 

 but evident carina on lower part of frons and base of clypeus; 

 middle part of the clypeus to near the base slightly flattened ; maxil- 

 lary palpus composed of six segments, labial of four; wings narrow 

 and relatively short, about double the width of the thorax ; venation 

 of wings similar to that in the genus Stietia: body slender; male 

 generic characters, if any. unknown.

 spots; labrum; mandibles, except tips; lower part of frons; scape; 

 basal segments of flagellum below; broad anterior orbits shortened 

 above ; narrow posterior orbits broad below ; tubercles continuous 

 with broad spot on sides of prothorax and with broad fascia on pos- 

 terior border of pronotum ; lateral lines and pair of large, longitudi- 

 nal, pear-shaped spots on scutum ; fascia on anterior border of scutel- 

 lum; narrow fascia on metanotum; arcuate fascia on propodeum 

 extended in a pair of points on its posterior surface; posterior lat-
