STUDIES IN THE FOSSORIAt WASPS. G99 



1 have little doubt that links will be discovered connecting both 

 sexes of this genus with Myzlne 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 difierences of neui-ation pointed out 

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

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

 blance to female Thynnidse of the genus Eirone, also to the 

 Bethylid genus Aj)enesia. I have not been able to examine the 

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

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

 contrasted with the shallowly emarginate eyes of Myzine. 



Braunsomebia atriceps, sp. n. 



$ . Nigra ; "mmulihtdls hasi, clypeo, antennis, thorace, segmento 

 7nediano, 2'>6dihus pyyidiocji^ue apice ferrihgineis. 

 Long. 5 mm. 



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

 inner margin near the apex, Head rectangular, a little broader 

 than long, very slightly convex, shining, with a few scatteied 

 punctures. Thorax shining, with a few scattered punctures on 

 the pronotum, the median segment more closely punctured. 

 Pronotum longer than broad, slightly naiTowed anteriorly, 

 narrower than the head by about one-third ; mesonotum very 

 short, the tegul?e rather better defined than in (luadraiicepjs ; 

 scutellum rounded posteriorly, broader than long. Median seg- 

 ment a little shorter than the pronotvnn, slightly broadened from 

 the base, a little broader than long and obliquely sloped 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 petiole not 

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

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

 dorsal segments 2-5 ; sixth segment smooth, pointed at the apex. 

 The constriction between the two basal ventral segments is well 

 marked. The eyes are smaller than in quadraticeps and are 

 separated from the posterior angle of the head by a distance 

 equal to about three times their own length.
