first flagellar joint unusually short, its shorter side being little longer 

 than second joint. Thorax shining; mesoscutum shining, minutely 

 punctate, notauli distinct only to summit of anterior slope; scu- 

 tellum sculptured like mesoscutum, ridged laterally but distinctly 

 carinate only at extreme base, broad; mesopleurum subpolished 

 rather densely finely punctate; metapleurum strongly convex, striato- 

 punctate; propodeum rounded, transversely finely striate, apophyses 

 weak, spiracles broadly oval; areolet triangular, petiolate; second 

 recurrent interstitial, nearly evenly curved througout; nervulus 

 postfurcal by nearly its length; postnervulus broken at about its 

 upper third; nervellus broken at about its upper fourth; legs 

 stout; hind femur barely two-thirds as long as tibia; hind tarsi 

 (broken) ; joints of middle tarsus relatively short and stout, apical 

 joint about as long as third, which is barely three times as long as 

 thick, claws small with about eight large teeth. Abdomen rather 

 stout; first tergite only a little more than three times as long as 

 broad at apex, spiracle at basal two-fifths; second tergite only one 

 and one-half times as long as broad at base. 



Rather pale testaceous; face, orbits, vertex, subalar tubercles, and 

 sides and apex of scutellum yellow and faint indications of this color 

 on margins of mesoscutum and in notauli; tarsi paler than rest of 

 legs; antennae concolorous, blackish apically; wings hyaline, venation 

 brown, stigma and costa pale. 



Male. — Length 12 mm.; antennae 12 mm. 



Essentially like female, but yellow markings of thorax more dis- 

 tinct and scutellum entirely yellow; tarsal claws not densely pectinate. 



Type-locality. — Illinois. 



Allotype-locality. — Near mouth of Four Mile Run, Virginia. 



Type.—Cat. No. 25987, U.S.N.M. 



Described from two females, the paratype from Ardmore, South 

 Dakota (E. G. Holt, September 25, 1915), and one male (W. L. McAtee, 

 September 17, 1916). 



The paratype is badly stained about the head but is otherwise 

 much like the type. In this specimen the hind tarsus is barely longer 

 then the tibia. It and the allotype were received from the Bureau 

 of Biological Survey, and the type from the C. F. Baker collection. 



PANISCUS TEMPORALIS, new species. 



Female. — Length 13 mm.; antennae 10 mm. 



Temples strongly buccate, fully as wide as eyes, weakly punctate; 

 face very broad, a third wider than frons, weakly elevated medially, 

 rather densely punctate and faintly shagreened; clypeus very broad 

 and short, nearly flat, very broadly arcuately truncate at apex, 

 sparsely punctate; frons flat, weakly transversely striate; ocelli
