160 THE DIPTERA-BRACHYCERA OF TASMANIA, 



little white pubescence at sides, especially posteriorly ; 

 scutellum red-brown without either bristles or pubescence. 

 Abdomen with the three first segments red, remaining seg- 

 ments reddish-black. Legs yellowish-red, the posterior 

 pair slightly the darkest; posterior tibiae with white 

 bristles. Wings yellow-brown, with all the posterior cells 

 and anal cell open, though the fourth posterior is 

 slightly, and the anal considerably, contracted on the 

 wing margin. 



Female resembles the ma^e very closely, but the thorax 

 is slightly browner, and the fourth abdominal segment 

 bears a white tonientose spot on each side. 



Variation. A male bred by Mr. Spry from material 

 obtained at Fern Tree Gully, Victoria, is only 11 mm. in 

 length, and ha.s the wings with basal two- thirds bright 

 golden yellow, apical third hyaline. 



E. iclineumonif ormis is widely distributed in the Tas- 

 manian bush, where it may be found resting on low vege- 

 tation, but it is by no means a common species. My dates 

 range from February 9 to March 3. 



31. Bathypogon, Loew. (Fig. 27.) 



Abdomen longer than the wings, not constricted at the 

 base ; wings very short, the fourth posterior cell closed at 

 some distance above the wing margin, the vein closing it 

 almost in a line with that closing the discal cell. 



Face with a large centre tubercle, which is covered with 

 a large bushy moustache, reaching almost to the antennae. 

 Antennae a little longer than the head, the first joint about 

 twice the length of the second, the third about twice the 

 length of the first and second together, and terminated by a 

 distinct pointed style. Thorax rather long, very bristly 

 posteriorly ; scutellum with marginal bristles. Abdomen 

 long and fairly stout, not in the least club-shaped or in. 

 any way constricted at the base, the sides either bare or 

 with short bristly hairs; genitalia of male large and pro- 

 minent. Legs stout and bearing long bristles. Wings 

 remarkabl}^ short ; the fourth posterior cell closed at some 

 distance above the wing margin, the vein closing it almost 

 in a line with that closing the discal cell ; the other pos- 

 terior cells open ; anal cell closed. 



The species belonging to this genus occur settled on the 

 ground in dry situations. I have noticed a specimen of 

 li. hracJiy pterins having as its prey a moth as long as itself. 

 In Tasmania two species are known to occur.
