the Asilida? of Australasia. 447 



The following species not known to me must remain in 

 Asilus in sensu lato for the pi-^sent : — _ - .jTf^ //."V '/L 



Asiliis acutangulatus, armafuP. australis. T copnahisJ 'fe3:PH^7'"'' '' 

 gmeivsniHe, filifera, fulvipubescens^ longiventris, nigrinuSj 

 rujicoxatus, rufometatarsus, fsetifemo raiu s'] vittipes, Macq. ; 

 helzehul, Wied. (v. d. Wulp could not find this type in the 

 Leyden Museum ; Wiedemann described it from unknown 

 locality, but later Macquart recorded a male he thought was 

 a specimen of this species from New South Wales) ; regius, 

 Jaennicke ; smiihii, Hutton. 



Asilus crabroniformis, L.^ in Kertesz's Cat., has Tasmania 

 given with a query as one of the localities in which it occurs ; 

 but this is probably an error on the part of Walker (see 

 Verrall, 'British Flies/ vol. v. p. 649, 1909). 



The following Walker types from Australia and Van 

 Diemen's Land are not to be found in the Brit. Mus. Coll., 

 and should be expunged from any future list : — 



Asilus elicitus. „ , 



Asilus alicis. • r^^— ^ / :^i^A -^ ^--^ 

 Asilus luctijicus. p ■ i - I, fhu^A 



Asilus aWgans. - .^t^e^-^»^ '^^^^ '^*^ "^^^ 



The following types from unknown localities are also not 

 to be found : — Asilus eanes, habnus, and inumbratus. 



Asilus antiorus and corythus are species of the genus 

 Fruct acanthus. 



The following types of Walker cannot be placed in their 

 correct genus, owing to their imperfect condition ; all, with 

 the exception of Asilus alcetus, are small species which will 

 not belong to Asilus in sensu stricto. 



Asilus obumbratus, Walker. 

 Dipt. Saimd. p. 145 (1851), et List Dipt. vii. Suppl. 3, p. 735 (1855). 



Type (female) from New South Wales (Saunders Coll.) 

 seems allied to the genus Cerdistus, but the ovipositor ends 

 in a fork. It is a small black species with apparently dull 

 yellow legs. 



Asilus alcetus, Walker. 



List Dipt. ii. p. 425 (1849), et vii. Suppl. 3, p. 736 (1855). 



? Asilus traehalus, Walker, Dipt. Saund. i. p. 143 (1851), et I.e. p. 738. 



This type is from Van Diemen's Land {R. Buller), in bad 

 preservation. A medium-sized greyish-black species.
