348 HYMENOPTEBA. 



Wings : the radial cellule extends beyond the apex of the third cubital cellule ; the 

 first abscissa of the radius is oblique, the apical abscissa curved ; the first transverse 

 cubital nervure is roundly elbowed at the middle, the second curved ; the third cubital 

 cellule is complete and is much narrowed at the bottom ; the first recurrent nervure is 

 received nearly in the middle of the cellule, the second almost interstitial. The tegulae 

 are moderately large, shining, and have some glistening depressed hairs. 



J 63. Sphaerophthalma intrepida. 



Long. 7 millim. <$ . 



Hah. Mexico, Teapa in Tabasco (H. H. Smith). 



Very nearly related to 8. volatilis, but smaller ; the abdomen from the basal segment 

 entirely rufous above and beneath ; the second cubital cellule wider at the top, where 

 it is nearly as long as the space bounded by the first transverse cubital and the first 

 recurrent nervures, the latter being distinctly received before the middle ; the third 

 cubital cellule wider at the bottom and receiving the recurrent nervure in the middle ; 

 the entire thorax covered with long silvery hair. 



Head as wide as the thorax, finely punctured, covered with long white hair ; a 

 broad shallow furrow on the front ; roundly narrowed behind the eyes, almost trans- 

 verse in front, rounded posteriorly. The antennae are stout ; the scape shining and 

 sparsely covered with white hair ; the third and fourth joints subequal. The pronotum 

 rounded at the base, semicircular at the apex, rather strongly punctured ; covered with 

 long fuscous hair, the apex with a fringe of shorter hair; the mesonotum shining, 

 bearing large clearly separated punctures; the scutellum with long pale hair; the 

 median segment reticulated ; the mesopleuree covered with long white hair. The 

 basal segment of the abdomen black, shining, punctured, bearing some long white hairs, 

 the other segments rufous ; the second segment punctured ; the apical segments fringed 

 densely with long rufous hair. The keel on the first ventral segment distinct, but 

 blunt, obliquely truncated at the base. The other ventral segments are rufous, except 

 the base of the second. The legs are black and are covered with white hair. Wings 

 pale fuscous ; the radial cellule projecting considerably beyond the apex of the third 

 cubital cellule ; the basal and apical abscissae of the radius curved ; the second cubital 

 cellule at the top as long as the part bounded by the first transverse cubital and the 

 first recurrent nervure, the latter being recurved before the middle of the cellule.
