from which a pair of yellowish " scythe-like" processes run 

 forwards and meet. Immediately above this there is a com- 

 plicated but rather weak mass of chitinised tissue (Fig. 12).' 



Female. — The female differs from the male in the follow- 

 ing characters : — Front equal to width of eyes. Lateral ventral 

 bristles almost as large as verticals. Eight frontal bristles 

 beside frontal stripe ; three others converging upon these 

 beside the eye. Lowest humeral bristle does not extend to 

 mesonotum. Femora not markedly hairy ; no " comb "^ 

 developed on second femur ; posterior tibia hairless. Abdomen 

 a little shorter but broader than thorax ; oval in shape, and 

 with the usual black and grey markings. 



A male of this fly was submitted to Dr. Aldrich, who 

 determined it, by an_ examination of the male genitalia, as 

 S. knabi Parker 1917. ' Mr. G. F. Hill of the Tropical Institute, 

 Townsville, kindly sent us some specimens which he found 

 to be co-specific with Taylor's type in the Institute Collection. 

 A comparison of the male genitalia of these forms, with the 

 specimen which Dr. Aldrich determined as S. knabi, shows 

 the two to be specifically identical, and to agree entirely, also, 

 with S. knabi as described by Parker. S. froggatti Taylor and 

 S. knabi Parker are therefore synonymous, the former having 

 a few months' priority. Townsend (1917, p. 191) created a 

 genus Glaucosarcophaga with S. knabi as type. If the genus 

 be accepted then the correct name of the type is G. froggatti. 



This fly has a very wide range. Taylor's material came 

 from Winton (Central Queensland) ; our own is from Brisbane ; 

 Dr. Parker's specimens were collected in the Philippine 

 Islands.
