brown spot below base of each; face and mouth-parts dull 

 testaceous 



T h o r a x : prothorax long and narrow, slightly wider behind, 

 dull brown with paler, longitudinal markings. Pterothorax 

 broader, similarly coloured and marked; underside pale testa- 

 ceous. Leys very long and slender; forelegs black, basal and 

 apical fourths of tibia testaceous;* middle and hindlegs testa- 

 ceous, the femora strongly tipped with black, the tibi« slightly 

 so; tarsal joints mostly black. 



Abdomen slender, dull grey-brown; 1 and base of 2 testa- 

 ceous, 3-8 with a basal, testaceous mark projecting apically into 

 a sharp point. 



Wings: venation brown, Sc and R speckled with whitish. 

 Forewiny with a narrow, black mark on pterostigma, several 

 blackish specks along posterior margin, and veinlets towards 

 apex mostly clouded with brown. Hindiviny with a diffuse 

 patch of dark brown just above posterior margin, two-thirds of 

 the distance along the wing from base, a touch of browti proxiraad

 Veinlets of pterostiyma in both wings whitish. In forewing, 

 only three cross-veins in radial space, the third being whitish. 

 Origin of lis about two cells' width proximad from level of 

 cubital fork: the oblique vein placed far beyond the fork (3-4 

 cells distant). 



//a6.— Linville, Q. (Brisbane River Valley). A single speci- 

 men, apparently a male, taken on February 22ndj 1915, by Mr. 

 E. J. Dumigan, to whom I dedicate the species 

 Type in Coll. Tillyard. 



Easily distinguished from D. lonyipennis Esb.-Pet.,(New South 

 Wales), by its larger, broader, and less pointed wings, less marked 

 with black or brown. In D. lonyipennis, also, the difference in 

 level between the origin of Rs and the cubital fork is greater. 



* I have used this word throughout as indicating a dull, pale yellowish- 

 brown, I.e., earthenware-colour (Lat. te><taceu><}. It has sometimes been 

 used to indicate a dull brick -red, i.e.., tile-colour. The Latin word admits 

 of both meanings.
