XLYII. — A Revision of the Asilitlae of Australasia. 

 By Gertrude Ricardo. 



[Coutimied from p, 160.] 



Dasypogon, Macquart. 



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



The species from Australia and Tasmania not yet assigned 

 to other genera from Dasypogon in sensu lato are the 

 following : — 



Dasypogon australis, Macq., Dipt. Exot. i. (2) p. 45 (1838). 

 Dasypogon albonotatus, Macq., 1. 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. iv. p. 06, pi. yi. fig. 9 (1849). 

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



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

 the Brit. Mus. Coll. 



Dasyjjogon australis, Macq. 



Type a female seen by me in the Paris Museum, 12. 4. 11. 



The 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 Dasypogon genus 

 in sensu stricto. It should be easily recognized by the 

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

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

 broad reddish-yellow segmentations, the apex has spines ; 

 no ovipositor visible. Legs yellowish. Thorax black, 

 shoulders reddish. Scutellum reddish, with long yellow 

 bristles. The brown colouring on the wings 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. 



Macqujirt 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 fifth segments. Face and 

 forehead golden yellow. Beard and the plain moustache 

 white. Legs reil, the anterior tibiie with a curved spine.
