N &0 RECORDS OF THE AUSTRALIAN MUSEUM. 



The second form, 31. convergens, God. and Frogg., which I 

 propose to reduce to varietal rank, loses the black colouration of 

 the thorax and head, which carry a number of black markings 

 upon a background of greenish-fuscous. This variety is found 

 in the damp ground near creeks and lagoons on the east coast 

 of New South Wales. It is generally smaller than the typical 

 form. It may be found on the edge of a lagoon, while, one 

 hundred feet up one of the enclosing hills the typical form is found. 

 The abdomen is of a paler yellow than that of the original species. 

 A faded Q of this variety is Goding and Froggatt's M. telxiope, 

 Walk., in the Macleay Museum. The size of the species varies 

 from 15 mm. to 25 mm. in length, and the wing-expansion from 

 38 mm. to 62 mm.

Obs. — The two species, though somewhat similar, cannot be 

 mistaken by any Held collector. The resemblance is stronger in 

 the £ forms than the £. Distant has been probably misled 

 either by examination of the $ or else by an error of the authors 

 in sending to him specimens of P. encaustica labelled /\ anuulata. 

 ,P. encaustica is a very old species of Germar's.
