[Continued from p. 160.] 



Dasypogon, Macquart. 



Illiger's Magazine f. Ins. ii. p. 70 (1803). 



The species from Australia and Tasmania not yet assigned 

 to other genera from Dasypojon in sensii lato are the 

 following : — 



Dasypogon australis, Macq., Dipt. Exot.i. (2) p. 45 (18.38). 

 Dasypogon albonotatus, Macq., I. c Suppl. ii. p. 49 (1846). 

 Dasypogon nigripennis, Macq., 1. c. Suppl. iii. p. 180, pi. i. fig. 10 



(1847), 

 Dasypogon nigrinus, Macq., 1. c. Suppl. iy. p. 66, pi. vi. fig. 9 (1849). 

 Dasypogon carbo, Walker, Dipt. Saund. i. p. 87 (1851). 



The type of this last is probably destroyed, not being in 

 the Brit. Mus. Coll. 



Dasypoc/on australis, Macq. 



Type a female seen by me in the Paris Museum^ 12. 4. II. 



Tlie head is gone, and Macquart makes no mention of it 

 in his description ; it is therefore impossible to assign it to 

 any genus^ apparently it will belong to the D'asypoydn genus 

 in sensu stricto. It should be easily recognized by the 

 winys, which are brown on the fore border, by the absence 

 of spines on fore tibicC, and by the black abdomen, with 

 broad reddish-yellow segmentations, the apex has spines ; 

 no ovipositor visible. Legs yellowish. Thorax black, 

 shoulders reddish. Scuteltum reddish, with long yellow 

 bristles. The brown colouring on the ivings extends along 

 the fore border to the apex, as far as the posterior branch of 

 fork of third vein^ fills the first basal cell, the extreme base 

 of the first posterior, and only touches the discal cell on its 

 border ; the fourth posterior cell is wide open^ anal not 

 quite closed. 



Macqunrt gives the length as 6 lines. 

 From New S. Wales. 



Dasypogon albonotatus, Macquart. 



From Tasmania. 



Described as having a long, slender, black abdomen^ with 

 white spots at sides of second to filth segments. Face and 

 forehead golden yellow. Beard and the plain moustache 

 white. Legs red, the anteiior tibiie with a curved spiue.
