Type.—Csit. No. 14827, U.S.N.M. 



Very similar in some respects to hergenstammi, but a bright yellow 

 colored species. 



PARASPINIPHORA DORSALIS Becker. 



This species has not yet been recorded from America, It resem- 

 bles slossonx, but has two pairs of dorso-central thoracic bristles; 

 the hypopygium is ''mattgeld" not shining; the bristle-like hairs on 

 the second and sixth segments of the abdomen are more noticeable 

 in this species (those are present in nearly all cases where these 

 segments are elongated) ; the hind tibia has two spines on the antero- 

 dorsal surface one at the basal third and one at near apex and one 

 on the antero-ventral surface at middle, and two end spurs on the 

 posterior side. The neuration is much as in slossonse. The female 

 has also four to five additional spines on hind tibia. In slossonae the 

 female has hind tibia as in male.
