D. rudh^ is a common species in the early springtime. 

 It occurs settled on stones and in similar situations. My 

 dates range from September 13 to November 9. It also 

 occurs in Victoria and New South Wales.

 (Itamus, Loeiv.) 



Ovipositor very long and laterally compressed; bristly 

 hail's of thorax short anteriorly, long posteriorly. 



Head somewhat projecting; moustache bushy, but not 

 nearly reaching to the antennae. Antennae slender, a little 

 longer than the head, the first joint two or three times 

 the length of the second, the third about equal to, or a 

 little longer than, the first two together, cylindrical, and 

 provided with a thin style. Thorax with short bristles 

 anteriorly, long posteriorly ; scutellum with two or four 

 marginal bristles. Abdomen long and narrow, with or 

 without weak side-bristles ; genitalia, of male large, and 

 differing in shape in almost every species; ovipositor of 

 female very long and laterally compressed, and apparently 

 including the sixth and seventh abdominal segments. Legs 

 of medium length, all joints bearing bristles. (In the 

 Palcearctic species of this genus the tibiee are extensively 

 bright orange, but this is rarely the case with the Aus- 

 tralian species.) Wings with the normal venation of 

 Asilus, frequently rilled, but never inflated. 



Neoitaimi.s is one of the most difficult of the Australian 

 genera. It contains a large number of closely-allied 

 species, w4iich can only be distinguished with difficulty, 

 the difficulty being increased hy the fact that the same 

 species is liable to vary considerably according to the part 

 of Australia in which it occurs. Of the seven known Tas- 

 manian species two apjDear to be peculiar to the island, 

 whilst the other live occur also on the Australian main- 

 land.
