AHT. 5 GENEKIC REVISION OF THE FOSSOEIAL WASPS PAEKER 145 



is black above, but of a light shade of ferruginous below. The inner 

 eye-margins are a trifle wider apart at the clypeus than at the vertex. 

 The frons is broad and between the antennae strongly carinate. The 

 basal half of the clypeus on the midline is also strongly carinate, 

 while the median apical portion is somewhat flattened. Except the 

 ridge of the carina and the apical flattened part, the clypeus is cov- 

 ered with fine, silvery pubescence. The anterior metatarsus bears seven 

 spines. The disk of the second sternite is shining and on either side 

 the midline are scattered coarse punctures, among which are numer- 

 ous fine punctures. Only a small, median anterior area is free from 

 punctures. The sixth sternite is slightly carinate on midline and is 

 closely covered with punctures, in which coarse and fine are inter- 

 mingled. The sixth tergite is broadly rounded at the apex. The 

 wings are clear and the second abscissa of both radiella and cubitella 

 is present, although the latter is much reduced. The pubescence on 

 thorax, propodeum, and abdomen is of normal character. The dorsal 

 surface of the abdomen, when light strikes it at the proper angle, 

 shows a beautiful, bluish iridescence, a character not commong among 

 species of this genus.

BEMBIX HEXASPILA, new species 



Type (female). — Black: labrum; mandibles, except tips; space 

 between antennae continued broadly upward to join, below anterior 

 ocellus, a transverse band that unites with the anterior orbits ; broad 

 anterior orbits almost interrupted below junction with transverse 

 band, but above it deflected inward to join the posterior orbits on 

 the vertex; scape, except black line above; posterior orbits broad 

 below; pronotum; broad lateral lines and broad U-shaped discal 

 mark on scutum ; broad continuous fascia on scutellum ; metanotum ; 

 broad, curved facia on propodeum covering most of its dorsal and 

 posterior surfaces; lateral angles and sides of propodeum; meta- 

 pleura ; mesopleura ; mesosternum, except pair of black spots anterior 

 to each middle coxa; very broad, continuous fasciae on tergites 1-5, 

 all acutely emarginate at midline on posterior border, the first with 

 a pair of rounded dorsal spots, of which one is not completely in- 

 closed, second and third each with a pair of elliptical dorsal spots, 

 and fourth and fifth bisinuate on anterior dorsal border; first ster- 

 nite; second sternite, except large central black spot and pair of 

 small anterior lateral black spots; third sternite, except large median 

 and pair of anterior lateral black spots; fascia on fourth resembling
