Heterogyna and Fossorial Hiimenoptera. 275 



thick fringe of bristles on each side near the eye, clypeus 

 in the ? rounded in front ; metathorax rugose in both 

 sexes, its basal area longitudinally striate ; abdomen 

 strongly punctured, basal segment covered with long 

 hairs ; all the segments in the ^ more or less hairy ; 

 apical segment flattened above, and largely punctured in 

 the S , transversely rugose in the ? , carinated on each 

 side, and somewhat rounded at the apex, with a slight 

 projection on each side ; under side of all the segments 

 in the S' with an apical fringe, and a few scattered hairs 

 on the disk, in the ? almost naked. 

 Length 12 — 16 mill.

Very like arenaria, but smaller, the puncturation of the 

 thorax larger and more remote, and the pubescence less 

 dense in the (? ; the clypeus in the ^ simply truncate at 

 the apex, and not obsoletely tridentate as in arenaria, 

 that of the ? slightly raised (but not free), deeply and 

 semicircularly emarginate in front ; basal segment of the 

 abdomen in the ? less hairy, and with only a very small 

 reddish yellow spot on each side ; apical segment rather 

 narrower at the apex, the fringe of hairs on its lateral 

 carinse longer ; penultimate segment of the J with a 

 small tuft of rigid pale setje on each side at the apex ; 

 legs in the ? fulvous, those of the 3' dark at the base of 

 the femora of the two front pairs, and with a dark ring 

 near the apex of the posterior pair. 



Length 9 — 11 mill.

Almost exactly like the preceding in colour and size ; 

 the 1st segment of the body of the ? however has larger 

 and paler yellow spots, and the posterior femora of the 

 (? have a wider black apical band ; the <? may be however 

 separated at once by the 3-dentate clypeus, and the 

 longer hairs of the abdomen beneath, and the ? by the
