longifnrca {similarly to the European D. sylvicola, Curtis, and the 

 Algerian D. fuscipes, Berg.) it is long. The discal cell wanting, 

 being opened posteriorly (into the fourth posterior cell), conse- 

 quently the anterior branch of the fourth longitudinal vein appears 

 as twice branched. The great cross- vein is situated much before its 

 usual place, sometimes its length distant before the inner end of the 

 fourth posterior cell (corresponding to the inner end of discal cell 

 in most other genera). The anal angle is not very prominent in 

 any of the species, but in some it is so reduced that the seventh 

 longitudinal vein runs very close to the margin. The stigma, 

 which is always distinct, is of a more or less oblong shape, and 

 fills up the space between the costa and second longitudinal vein 

 from opposite origin of praefurca to tip of first longitudinal ; at 

 each end of the stigma a more or less distinct white spot or light 

 reflection seems always present. 



I quite agree with Bergroth (Wien. Ent. Zeit. VITI. 1889, p. 

 114), that Ajyeilesis cannot be maintained as a genus distinct from 

 Dolichopeza. The only diff'erence pointed out by Osten-Sacken is 

 the length of the digitiform appendages which ai-e very conspicuous 

 in D. cinerea, Macq., and some other species, while they appear to 

 be very inconspicuous in the hitherto known examples of Doli- 

 choj)eza ; but I do not consider this character of more than sub- 

 generic importance, even if it is that : at any rate it does not appear 

 to be supported by any other peculiarities. 



Only about half a dozen species of Dolichopeza appear to have 

 been yet described ; two or three from Europe (V. z.-b. G. Wien, 

 XIX. pi. IV. 1869, figs, of wings by Mik), one from Algeria, 

 another from Madagascar, and one from N. America. Eight are 

 now characterized from Australia, seven of which are new. 

 Doubtless numerous other species will be readily discovered. 



All the following described species are found in damp shady 

 situations. They may be at once recognized by their peculiar 

 dancing flight ; and on account of their extremely delicate and 

 slender structure are extremely diflicult to see when flying.
