Family Scoliid^. 



Subfamily Eliding. 



Braunsomeria, gen. nov. 



5 . Apterous ; mandibles acute at the apex, with a rather in- 

 distinct tooth on the inner mai-gin near the apex ; antennas twelve- 

 jointed, the first joint of the flagellum very small and almost con- 

 cealed by the apex of the scape. Head almost rectangular, the 

 posterior angles slightly z^ounded ; eyes oval, touching the base of 

 the mandibles, rather small, separated by a distance at lea^t as 

 great as their Qwn length from the posterior angles of the head ; 

 ocelli absent, their pqsition indicated l^y large punctures. Thorax 

 much narrower than the head ; prpnotum rather longer than its 

 greatest breadth ; m^SQnotum very short, almost covered by the 

 pronotum, the tegulse more or less developed ; scutellum narrower 

 than the pronotum, broader than long ; median segment nearly as 

 long as the pronotum, flattened on the idorsal su^-face, broadened 

 from the b.ise to the ^.pex. Sides of the head and thorax and base 

 of the abdomen thinly covered with long hairs. Abdomen longer 

 than the head and ibhprax combined, shining, the apical segment 

 long and more or less acute at the apex, stricture between the first 

 and second ventral segments well devploppd. Intermediate coxte 

 rather widely separated, posterior coxje contiguous, intermediate 

 and posterior tibise spinose, tarsp,l ungues simple. 



cS . Winged ; stigma rathef large, situat^d at about three-fifths 

 from the base of t|ie wing ; radial cell shorter than the stigma ; 

 three cubital cells, the second and third small, not reaching the 

 apex of the radial cell, each receiving a recurrent nervure ; cubital 

 and discoidal nerviares not continued beyond the cells. Medial 

 cell of the hind wing not emitting veins from the apex. Antennte 

 in the typical species long and slender, thirteen-jointed, the first 

 joint of the flagellum almost concealed in the apex of the scape, 

 the antennae much longer than thp abdomen ; antennal tubei'cles 

 well developed. Head strongly convex ; ocelli present. First 

 abdominal segment with a short petiole, the segment, including 

 the petiole, a little longer than the se.cond segment, suddenly 

 widened at thp apex of the petiole. Apical segment with a re- 

 curved spine, the apical emargination of the dorsal segment 

 shallow. Eyes entire, not emarginate. 



The characters given here for the male will doubtless be found 

 not to apply ]bo all species of the genus ; but the important 

 characters in the neuiution separajbing the males from Myzine 

 are the larger stigma, the blunter apex of the radial cell, the fact 

 that the cjibital and discoidal nervures are not continued beyond 

 the cells as in ^lyzine, and that no v.eins are emitted from the 

 median cell pf the hind wing, there being two veins in Myzine.
