ABT. 6 NOTES ON ORIENTAL SAPROMYZID FLIES MALLOCH 47 



57. Ocellar bristles reduced to microscopic hairs, tlie orbital bristles very long 



and strong, tlie upper one longer than height of head, the anterior pair 

 a little wider apart than upper pair, no distinction between orbital 

 stripes and remainder of frons. all shining; a glossy fulvous yellow 

 speces with five black marks on dorsum of thorax, the one on each side 

 at middle filling all of length between humeral callosity and base of 

 wing, and quadrate in shape, the posterior pair covering basal angles of 

 scutellum as well as a small portion of posterior lateral angles on mesono- 

 tum ; sides of abdomen broadly black vittate ; wings immaculate, 



maculifera (de Meijere). 



Ocellar bristles well developed, extending to at least middle of frons ; species 



not colored as above 58. 



58. Mid tibia abnormally haired ; preapical dorsal bristle on fore tibia abnor- 



mally long and slender, extending to, or almost to, apex of basal segment 



of tarsus (males) 59. 



Mid tibia without abnormal hairing; preapical dorsal bristle on fore tibia 

 very much shorter than basal segment of fore tarsus, and usually 

 rather stout 60. 



59. Mid tibia with very fine curled hairs on apical third of posteroventral sur- 



face which are no longer than tibial diameter; hind femur without 



outstanding anteroventral bristles crinita, new species. 



Mid tibia with dense straight bristly hairs on entire length of posterior 

 surface, which are much longer than the tibial diameter, and dense short 

 fine hairs on ventral surfaces ; hind femur with a series of fine bristles 

 from base to middle on anteroventral surface, longest apically. 



hirtitibia, new species. 



60. Wings without conspicuous markings, rarely with the extreme bases infus- 



cated, or the outer, or both cross veins, slightly clouded 61. 



Wings with a faint, but evident, pale yellowish clouding along the longi- 

 tudinal veins and on outer cross vein ; head entirely black ; thorax and 

 abdomen brownish testaceous, dorsum of former, and basal four tergites 

 of latter, black ; knobs of halteres dark brown ; hypopygium as Figure 61. 



strigipennis (de Meijere). 



Wings with quite evident dark markings in addition to any at extreme bases 

 or over the cross veins 107. 



61. Extreme bases of wings infuscated; black species, with the knobs of 



halteres black; thorax with a trace of white dusting round anterior 



spiracle, and on anterior margin of mesonotum 62. 



Bases of wings not infuscated 65. 



62. Superior claspers of male hypopygium with three or more short teeth or 



points projecting at right angles (fig. 62) dentifera, new species. 



Superior claspers of male hyiwpygium with at most two processes, which 

 both project downward 63. 



63. Hypopygium with two pairs of large black equal-sized processes, one di- 



rected forward, the other backward (fig. 63) opposita Malloch. 



Hypopygium with the forwardly directed pair of processes much smaller 

 than the other 64. 



64. Inner process of superior clasper slender, with a rounded apex (fig. 64). 



maquilingensis, new species. 

 Inner process of superior clasper stouter, acute at apex (fig. 65). 



trispina Malloch. 

 Inner process of superior clasper leaflike (fig. 66) folifera Malloch.
