This is a variable species ; a single female from New South 

 Wales, Sydney (Jan.) seems to agree with Signoret's description 

 and figures, except that the eyes in Signoret's figure of the insect, 

 are represented as not very decumbent on the pronotum and far 

 from contiguous with the base of the tegmina. Beside this there 

 are 4 males (not females, as wrongly stated in the description) 

 of the var. syrtidis, a series of males and females very like the 

 type, but differing in the colouring of pronotum, &c., (i. e., the 

 j^resence of 5 or 6 brown spots along the anterior margin) and in 

 the colour and pattern of the frons ; it is unnecessary to bestow 

 ori them a varietal name. The figure of the face (1. c, Pl. 24, 

 f. 9) of var. syrtidis gives a false impression (and refers rather 

 t( the type) as the whole of the face is black except narrow lines 

 on the frons, and the antennae. The venation varies very little, 

 sometimes there are 2 or 3 crossveins in the sutural area, some- 

 times these are absent. Subcostal cell divided by a somewhat 

 ol clique transverse vein about the middle, a little variable, of the 

 first subapical (sometimes by 2 clqse together.) The 3 subapical 

 cells extend apically about equally far.

var. syrtidis, Bundaberg (type, Oct.) Cairns (July) and Syd-

The genitalia appear identical in these forms, nevertheless I 

 should have retained syrtidis as a good species, had not Dr. Per- 

 kins taken a male with a female of the second variety and a male
