 Asilus centho, S , Walker. 

 Asilus i^lanus, § , Walker. 



The types of amycla and centho are from New S. Wales; 

 the type o( planus from Australia. 



There is a long series of specimens in the Brit. Mus. Coll. 

 from Burpengary, Queensland. The identification of this 

 apparently common species with Asilus inglurius, Mackay, 

 is given on the authority of Schiner, who confidently asserts 

 it, but the original description consists of merely a few lines. 

 Schiner suggested that A. planus and probably A. amycla were 

 synonyms of it, and was correct. The species is easily dis- 

 tinguished by the bushy bright yellow hairs on the three 

 basal segments of abdomen and by the red legs with tarsi 

 black. 



Length, S ~^, ? 24 mm. 



A series of this species is labelled in the Paris Museum as 

 Asilus sericeivent7is, eYidenily a MS. name only of Macquart's.
