STUDIES IN THE FOSSORIAL WASPS. 099 



1 have little doubt that links will be discovered connectino' both 

 sexes of this genus with Myzine through the short- winged Pseudo- 

 meria section in the females, and through species with somewhat 

 more extended neuration in the males. But the apterous con- 

 dition of the female and the diiierences of neuration pointed out 

 in the description of the male seem to me to be suificient reason 

 for founding a new genus. The female shows a strong resem- 

 blance to female Thynnidaj of the gexius Mrone, also to the 

 Bethylid genus Apenesia. I have not been able to examine the 

 mouth-parts, but it is likely that they wqukj show atrophy of 

 some parts. The entire eyes of the male are also noticeable as 

 contrasted with the shallowly emarginate eyes of Myzine. 



Braunsomeria atriceps, sp, n. 



5 . Nigra ; onandihulis basi, clypeo, antennis, thorace, segmento 

 mediano, pedihus pygid>ioqi(,e apice ferrugineis, 

 Long. 5 Qiim. 



2 . Mandibles acute, with a very small ill-defined tooth on the 

 inner margin near the apex, He£),d rectangular, a little broader 

 than long, very slightly convex, shining, wjth a few scattered 

 punctures. Thorax shining, with a few scattered punctures on 

 the pronotum, the median segment more glosely punctured. 

 Pi-onotum longer tbaq. broad, slightly nari'owed anteriorly, 

 narrower than the he^id by abgut one-third ; mesonotum very 

 short, the tegulas rp,ther better defined than in qtuulraticeps ; 

 scutellum rounded posteriorly, broader than long. Median seg- 

 ment a little shorter than the pronotuni, slightly broadened from 

 the base, a little bro£i,der than long and obliqiiely sipped poster- 

 iorly ; sides of the thorax and median segment sparsely clothed 

 with long yellowish hairs, Abdomen shining, finely aciculate, 

 the basal segment truncate anteriorly, with a short petiqle not 

 more than half as long as the posterior coxge ; the third segment 

 the broadest ; a semicircular small raised mark on each bide of 

 dorsal segments 2-5 ; sixth segmgnt smqoth, pointed at the apex. 

 The constriction between the two basal ventral segments is well 

 marked. The eyes are smaller than in quadratica'ps antl are 

 separated from the posterior angle of the head by a distance 

 equal to about three times their own length.
