376 HYMENOPTERA. 



with a rounded slope, and covered with long white hair. The abdomen longer than 

 the head and thorax united ; the petiole twice as long as broad, dilated towards the 

 apex, closely punctured, and covered with long soft white hair, which is darker in 

 tint on the upper than on the lower side, ferruginous in colour like the thorax ; the 

 rest of the abdomen deep black, covered, especially at the apex of the segments, with 

 long soft white hair ; the second segment above and beneath is indistinctly punctured. 

 The legs are of a darker ferruginous tint than the thorax, the four hinder femora and 

 the tibiae more or less blackish, and are covered with long white soft hair. The wings 

 are hyaline, very slightly suffused with a smoky tint below the stigma ; the stigma and 

 the costa immediately beyond the radial cellule deep black. The apex of the radial 

 cellule is rounded, and extends beyond the apex of the third cubital cellule ; the first 

 and second transverse cubital nervures are distinctly traced and are curved, the third is 

 rather faint, but still visible ; the recurrent nervure is received in the basal third of 

 the cellule. 



132. Sphaerophthalma gamelia. 



Long. 11 millim. c? . 



Hab. Guatemala, Capetillo (Champion). 



Similar in coloration to S. ceax, except that the antennae at the base are coloured 

 like the flagellum ; the legs bear much more black on the femora and tibiae ; the 

 petiole is longer, and is not so much dilated towards the apex, the apical half also 

 being black ; the wings are darker in tint ; and the radial cellule is larger compared 

 with the cubitals. 



The head is nearly as wide as the mesothorax ; the vertex indistinctly punctured ; 

 the front almost impunctate, depressed in the centre ; the whole head covered with 

 long pale fuscous hair. The antennae are nearly as long as the head and thorax united ; 

 black, the extreme base only being rufous ; underneath, the flagellum is duller in tint 

 and it bears an indistinct pile ; the pile on the scape is longer and paler ; the third 

 and fourth joints are subequal. The thorax is rufous, covered with long pale fuscous 

 hair ; the pronotum finely, the mesonotum much more strongly punctured, and with 

 the parapsidal furrows distinct and deep ; the mesopleurae not very strongly punctured ; 

 the metapleurae and the median segment reticulated. The abdomen is distinctly longer 

 than the head and thorax united, deep black, except the petiole, which is rufous at 

 the basal half; the petiole is more than twice as long as broad, and not much dilated 

 towards the apex ; the petiole and the second segment covered, but not thickly, with long 

 fuscous hair ; the edges of the other segments fringed with long white hair ; the basal 

 segment indistinctly punctured, the others impunctate ; the ventral segments are 

 fringed with long white hair. The legs are black and covered with long soft white 

 hair ; the tarsi with the hair closer and shorter ; the calcaria are fuscous. The wings
