mandibles, except at tlie apex, an irregulär mark ou the 

 sides of the middle lobe of the mesouotuui, tegulae, 2 marks 

 wider thau loug ou the sides of the scutellum, 2 oblique 

 oues, louger thau broad ou the sides of the post-scutellum, 

 a trausverse oue, rouuded in front, ou the base of the meta- 

 uotum, a larger mark, about 4 times louger thau broad, ou 

 the ceutre of the propleurae, au irregulär mark, broadest 

 behiud, on the base of the metapleurae and au irregularly 

 rouuded one ou its apex, almost ou the metauotum, and 2 

 marks, broailer thau loug, and rouuded at the sides, on the 

 basai abdomiual segmeuts, yellow. Legs and autennae 

 rufous-fulvous. VViugs hyaline, the stigma and nervures black. 

 -- Leugth 12 mm, terebra 5 mm. 



Head smooth, shiuiug, bare; the ocelli in a curve, the 

 hiuder separated from each other by the same distauce they 

 are from the eyes; o^'^^ joint of autennae sligiitly longer thau 

 the scape and slightly shorter thau the 4tli. Mesouotum 

 coarsely trausversely striated, the basai half of the middle 

 lobe widely, deeply fnrrowed down the middle. Scutellum 

 coarsely irregularly striated ; the base of the metauotum ob- 

 liquely, stoutly striated; the rest smooth, with a fsw irre- 

 gulär transverse keels. The base and apex of propleurae, 

 the lower pavL. of the meso-, irregularly in the centre and 

 the greater part of the metapleurae, longitudiually striated. 

 Claws with 3 teeth ; the apical louger and thiuuer, the basai 

 shorter and thicker thau the middle tooth. First transverse 

 cubital nervure rouudly curved, obliquely sloped above; the 

 2i<i is straighter and more oblique, the l*^t récurrent nervure 

 is received about the leugth of the l^t transverse cubital 

 nervure behiud it. Malar space longer thau the scape of 

 anteuuae. 



This species has the 1^^ récurrent uervure as in Pamme- 

 gisclda, not interstitial, or received near the tip of the l'^^t 

 cubital cell as iu the typical species of Fristaulacns. I am 

 not sure but that this species may be identical with Aulacus 

 flavognttaUis West. The latter (or what he supposed to be 

 the latter) is described iu fnll by Scltletterer iu his Mouograph 

 (Ann. K. K. Hof. Mus. 1880) but no mention is made of the 

 claws being pectinated.
