Mr. J. R, Mallocli on Exotic Muscaridfe. 415 



Eyes almost bare ; froiis one- third of the head-width ; 

 each orbit with one backwardly directed supraorbital ; para- 

 facial at base of antenna nearly as wide as third antennal 

 segment, becoming linear at middle of face, the latter concave 

 in profile ; longest hairs on arista shorter than width of 

 third antennal segment. Thorax with two or three pairs 

 of stout presutural acrostichals, three pairs of postsutural 

 dorso-centrals, and no prealar ; hypopleura bare. Fore 

 tibia without a median posterior bristle ; fore tarsus longer 

 than fore tibia, without outstanding sensory hairs on posterior 

 side of basal segment ; mid-tibia with two posterior bristles ; 

 hind femur with four or five long bristles on apical half of 

 antero-ventral surface, and a few setulose hairs on basal half 

 of postero-ventral surface ; hind tibia with two antero-dorsal 

 and two or three antero-ventral bristles, calcar long. Wings 

 normal.

Tyi^e and paratype, Burpengary, Queensland, 5. xii. 1899 

 {T. L. Bancroft). 



* I desire to state that the poor condition of the paratype is 

 due to an accident. When I had the specimen under the 

 microscope, holding it by the long pin through the mount 

 with my left hand, the electric lighting system suddenly 

 failed owing to a, violent thunderstorm that was raging that 

 night and I was left in pitch darkness. In attempting to 

 take hold of the head of the pin with my right hand to place 

 the specimen back in the box I accidentally laid hold of the 

 wrong pin, that upon which the specimen was mounted, in 

 the dark, with the result that the specimen is now rather 

 badly crushed, though recognizable.

 Jacial at base of antennse as wide as third antennal segment, 

 widened below, the vibrissal angle much produced ; cheek

 arista with its longest hairs equal in length to width of third 

 antennal segment. Thorax with three pairs of postsutural
