428 Phoridae. 



13. Gymnopliora Macqu. 



Species of medium size. Head a little longer than in tlie other 

 genera, with the posterior side a little arched and the frons flat ; it is 

 somewhat triangular in profile. Frons aboiit as high as broad, it is 

 a little narrowed anteriorly, the front margin is triangularly produced 

 and has above a small, elongated impressed pit, but there is no longi- 

 tudinal middle furrow; of frontal bristles there are only four in a row 

 on vertex, and they are small; in some species also the outer bristles 

 of the next row are present, they are quite small and placed near the 

 upper outer bristles, they may be individually absent or present, 

 and, likewise individually, there may be four bristles developed in 

 this row; for the rest the frons has short hairs. Eyes hairy. Antennæ 

 small, third joint globular with a long, pubescent, dorsal arista with 

 the two basal joints short. Palpi somewhat small, club-shaped, with 

 short bristles. Clypeus somewhat protruding, most in the female. 

 The postocular bristles are only small hairs and the lower are not 

 larger; there are no postvertical bristles. The jowls are a little descend- 

 ing below the eyes; the oral aperture large; there are no oral nor 

 genal bristles, only small hairs along the oral margin. Thorax has 

 behind, in front of scutellum a flattened area, from which two more 

 or less impressed lines stretch forwards to the anterior end; also the 

 transverse furrow is a little indicated ; thorax has short hairs and two 

 small dorsocentral bristles, placed far towards the sides. Scutellum 

 has four small bristles, likewise towards the sides, individually six 

 bristles may occur. Mesopleura with some few hairs above. Abdomen 

 has in the male the sixth segment elongated. Hypopygium is generally 

 hidden in the sixth segment, only rarely exposed; as far as I have 

 been able to see (mainly in arcuata) the tergite is symmetricai or 

 nearly so, shining, between the side parts the anal tube as usual 

 projects, it is short or a little longer, depressed and hairy; there is the 

 curious faet that the hypopygium is always turned to the left so 

 that the anal tube is seen on the left side; below, that is opposite the 

 anal tube, on the right side, a curious, flat and pointed long process 

 is seen, I think answering to the ventral plate; there is moreover a 

 large and complicated subanal body. In the female abdomen is some- 

 what curious; it has generally not tergal piates on all six segments, 

 but, according to the species, the fourth, the fourth and fifth, or the 

 third, fourth and fifth segments are without tergites; only in one 

 species {integralis Schmitz, non-Danish) there are tergites on all
