PARASPINIPHORA MULTISERIATA Aldrich. 



Plate 35, fig. 5. 



This very distinct species is represented in the collection by three 

 specimens — one (the type) from Lawrence, Kansas, one from Rox- 

 borough, Pennsylvania, and one from Atherton, Missouri. The 

 peculiar transverse rows of short bristles on the hind tibia, which also 

 occur on the basal half of the mid tibia, separates this species from 

 its congeners; besides this feature it has only two scutellar bristles; 

 the hind tibia has one spine at the basal third and one at apex on 

 antero-dorsal surface; and the hind metatarsi have 4-5 setulae longer 

 than the fringe of bristles similar to those that occur in erythronota 

 Strobl. This last feature not in original description. I have seen a 

 male of this species from Fremont, Nebraska (O. A. Johannsen), 

 July 27, 1909. 



PARASPINIPHORA ERYTHRONOTA Strobl. 



This is a species that in all probability will occur in America. The 

 hind tibia has one spine at the basal third and one at near the apex 

 on the antero-dorsal surface, and three end spurs on the posterior 

 surface. It differs from multiseriata in having four scutellar bristles, 

 and in being darker, especially in the color of the abdomen. The 

 neuration is very similar to that of multiseriata, but there is no peculiar 

 bristling of the hind and mid tibiae as in that species. 



PARASPINIPHORA SLOSSON^E, new species. 



Plate 35, fig. 1. 



Male and Female. — Yellow, shining; frons yellow, theocellar triangle 

 brown, bristles strong, the center pair of bristles in first row low down 

 close to post-antennals, the outer pair almost in transverse line with the 

 center pair in second row, which are ver}'- much lower on frons than the 

 outer pair in same row, antennae of moderate size, clear yellow, arista 

 dark, pubescent, palpi small, yellow, weakly bristled; thorax with 

 one, or two, pairs of dorso-central bristles, numerous short hairs, and 

 sometimes three indistinct reddish stripes, scutellum with four equal 

 bristles ; abdomen with the anterior mai^ns of segments 2-5 more or 

 less black, sometimes broadly so, second segment in male distended 

 laterally and very bristly in both sexes, sixth segment with long 

 preapical bristles, hypopygium shining, yellow, anal protuberance 

 short, blunt, yellow haired, fore and mid tibiae with the usual spines, 

 hind tibiae with one spine at basal third, and one at near tip on 

 antero-ventral surface, one at just above middle on nearly the dorsal 

 surface, one at above middle on nearly the ventral surface, and one 

 at near apex on anterior surface, as well as two strong and one Aveak 

 apical spurs; costa to middle of wing, first division twice as long as
