received close to the basal third of the cellule, the second shortly before the middle ; 

 the transverse basal nervure is not interstitial. 



144. SphaBrophthalma severa. 



Long. 9 millim. <5 • 



Hab. Mexico, Northern Sonora (Morrison). 



Very near to S. laerma, but with the hair on the head and thorax longer and thicker ; 

 the furrows on the median segment much less distinct, almost obsolete ; the radial 

 cellule shorter and broader ; the apical and basal abscissae of the cubitus curved, not 

 sharply oblique ; the second cubital cellule at the bottom shorter, not being much 

 longer than the space bounded by the second recurrent and the third transverse cubital 

 nervures ; and the stigma black, not piceous. 



The head is not, or very little, narrower than the mesothorax, shining, sparsely 

 haired ; black, behind the eyes with a piceous tinge, impunctate ; the ocelli large, 

 raised ; the head behind the eyes rounded, being there not half the length of the eyes ; 

 a shallow furrow connects the hinder ocelli, and there is an indistinct one in front of 

 the anterior ocellus. The labrum and clypeus are piceous, shining, almost bare ; the 

 clypeus in the centre roundly dilated ; the space between the antennas almost bare. 

 The mandibles are deep piceous, the tips black ; shining, sparsely covered with white 

 and golden hairs; towards the base, on the outer side, there is an elongated depression. 

 The antennas are stout, nearly as long as the head, thorax, and basal two segments of 

 the abdomen united, not tapering much towards the apex ; the third and fourth joints 

 subequal, the third a little curved; the scape with some moderately long white hair; 

 the flagellum almost bare, The thorax shining, sparsely covered with long white 

 hair ; the mesonotum and median segment covered, but not thickly, with long, soft, 

 white hair; the mesonotum impunctate, the lateral furrows narrow but distinct, and 

 commencing not far from the base ; the scutellum very shining, not narrowed towards 

 the apex, being of nearly equal width throughout. The median segment short, shining, 

 impunctate, rather thickly covered with soft white hair ; at the base in the middle 

 there is an area twice as long as broad, and sharply pointed at the apex, the two keels 

 uniting there; there are no keels outside these. The pleurae are shining, sparsely 

 covered with long, soft, white hair; the propleurse almost impunctate; the mesopleurse 

 have distinctly separated round shallow punctures, but are impunctate at the base and 

 the apex ; the metapleurae are indistinctly punctured at the base and apex only. The 

 petiole is narrowed at the base, at the apex as wide as the base of the second segment, 

 impunctate, sparsely covered with long pale hair; beneath it is flat, impunctate, 

 obscurely shagreened and sparsely covered with pale hair, the centre with a straight 

 furrow, the sides keeled. The other abdominal segments are shining, impunctate, and 

 sparsely covered with long fuscous hair. The legs are of a paler colour than the body,
