SARCOPHAGID FLIES FROM SOUTH-EASTERN QUEENSLAND. 79 



pointed and bare ; the remainder strongly hairy. Accessory 

 plates very large, dark brown and hairy. Claspers shiny 

 black. First segment of penis brown ; second more heavily 

 chitinised, black, in parts brown, the outer portions yellowish 

 or whitish. It is a relatively simple organ with a pair of short 

 forwardly directed ventral processes, and a large irregular 

 chitinous mass above and anterior to these (Fig. 5). 



Female. — This differs from the male in the following 

 characters : — Front about as wide as eyes. Lateral verticals 

 well developed. A row of eight frontals beside frontal stripe, 

 and three larger ones beside eye. Scutellum slightly more 

 abbreviated than in male. Thoracic chsetotaxy as in male, 

 except that the apical scutellars are absent. Thorax mode- 

 rately hairy beneath. First leg not hairy ; the second femur 

 is remarkable in that it has a well-developed " comb'* of 

 eight bristles, such a structure being here confined to the 

 female, whereas normally it occurs only in the male. Third 

 tibia not hairy. Abdomen a little more rounded than in male. 

 Dorsal longitudinal line extends definitely on to last segment. 



Described from a number of males and females bred from 

 decaying meat in Brisbane in September 1920.
