TAXONOMY OF MUSCOIDEAN FLIFS — TOW XSFXD 49 



forms which are here referred to the latter, and upon which there 

 has in the past been any question as to position, are: 



AXTHOMYIOIDEA 



Myiospila meditabunda et spp. — No hypopleural nor pteropleural bristles or 

 hairs. Sternopleural bristles 1. 0. 2. A weaker sternopleural bristle below first 

 one, so as to appear 2. 0. 2. Venation like Stomoxys. 



Muscina stabulans et spp. — No hypopleural nor pteropleural bristles or hairs. 

 Sternopleural bristles 1. 0. 2. Venation like Stomoxys. 



Muscina ccesia (det. Coquillett).— No hypopleural nor pteropleural bristles 

 or hairs. Sternopleural bristles 1. 0. 2. Venation typical anthomyiid. 



Cyrtoneura podagrica, gluta, et spp. 



Pararicia pascuorum et spp. 



Clinopera frontina et spp. — No hypopleural nor pteropleural bristles or hairs. 

 Sternopleural bristles 1. o. 2. 



These forms have heretofore been classed in the old Muscidse s. str. by 

 Williston, van der Wulp, and Brauer. It is believed they should be excluded 

 from the Muscoidea on the general averages of their characters. 



MUSCOIDEA 



The following forms here included in the Muscoidea were referred 

 "by Girschner to his Antinomy iden : 



Musca domestic®, corvina, et spp. — No hypopleural hairs. Distinct ptero- 

 pleural hairs. Sternopleural bristles 1. o. 2, but in some the last two bristles 

 are separated so as to appear almost like 1. 1. 1. Typical Muscoidean venation. 



Stomoxys calcitrans et spp. — Hypopleural hairs, also pteropleural hairs. 

 Sternopleural bristles 0. o. 1. Fourth vein bent, arcuate, partly continuous with 

 hind border. Proboscis adapted for bloodsucking. 



Lyperosia irritans et spp. — No hypopleural bristles. Pteropleural hairs pres- 

 ent. Sternopleural bristles none, o. 0. 0. Aberrant venation ; fourth vein 

 hardly bent, yet apical cell narrowly open at wing-tip; third vein bulged up- 

 ward, convex in front or above. Proboscis adapted for bloodsucking. 



HcEinatobia stimulans et spp. — -No specimens for study. 



Graphomyia maculata, americana (det. Coquillett), et spp. — Hypopleural 

 hairs present. No pteropleural bristles or hairs. Sternopleural bristles o. o. 2. 

 Fourth vein arcuate at bend. 



Synthesiomyia brasiliana et spp. — Hypopleural hairs strong, quite bristly 

 No pteropleural hairs. Sternopleural bristles I. 0. 2. Fourth vein arcuate at 

 "bend. 



Glossina longipalpis et spp. — No hypopleural hairs or bristles. Distinct black 

 pteropleural bristles, with yellowish hairs also. Sternopleural bristles r. o. 2. 

 Venation aberrant, in CEstrid direction ; apical crossvein continuous with pos- 

 terior crossvein, fourth vein deeply arcuate before small crossvein so that 

 latter appears continuous with the section of fourth vein following it. 



Morellia violacea (det. Coquillett, Brazil), micans Macquart (det. Coquillett, 

 Maine), et spp. — No hypopleural hairs. Pteropleural hairs present, bristly 

 hairs in micans. Sternopleural bristles I. 0. 2. Fourth vein arcuate at bend.
