Hormioinae. 



Pegarthriim gen. uov. 



Maxillary palpi with the 2"*^ joint swollen, moderately 

 thick at the base, becoming gradually widened towards the 

 apex, where it is twice the width of the 3''^, which is also 

 swollen, straight on the outer, rounded on the inner side ; 

 the 4"^ is also swollen, but not so much as the S''^, the 5^^^ 

 of normal thickness and not half the length of the penultimate ; 

 the 2"*^ ioint is longer than the S""*^ , which again is lonorer 

 than the 4^^\ Mandibles broad, bidentate, the teeth not very 

 clearly separated, the lower one small. Temples and occiput 

 not margined. Wings with 3 cubital cellules, the radial cellule 

 long, reaching to the apex of the wings ; the radius issues 

 from near the basal fourth of the stigma. The transverse 

 median nervure is received distinctly beyond the transverse 

 basal ; the recurrent in the apex of the 1'''^ cubital cellule. 

 Parapsidal furrows distinct, the mesonotum being distinctly 

 trilobate ; there is a clearly defined furrow on the lower part 

 of the mesopleura. Abdomen longish ovate, with 8 segments; 

 there is no area on the base of the 2"'^ segment. Anal nervure 

 interstitial. Head not cubital, distinctly contracted behind the 

 eyes. Sutariform articulation distinct. Antennae at least 26- 

 jointed (the apical joints are broken off), sides of metathorax 

 rounded. 



This genus cannot well be confounded with any of the 

 described genera of Hormiini. The abnormally dilated palpi 

 afford a ready means of distinguishing it.
