424 STUDIES IN AUSTRALIAN NEUROPTERA, viii., 



Head blackish-brown above, tbe eyes grey-black; antennae 

 dark brown, with two conspicuous creamy areas at their bases, 

 forming a kind of inverted V-mark between them on the frons; 

 below this a conspicuous, black, transverse band from eye to eye; 

 clypeus and mouth-parts a medium brown. 



Thorax hairy above, brownish, paler on sides; legs brown. 



Wings: — Forewiugs fuscous, semi transparent ; hindwings 

 somewhat paler. Costal space of forewing not very much broad- 

 ened; its veinlets set close together, and very few of them branched; 

 humeral recurrent vein short, usually with only a single anterior 

 branch to it. The single radial sector of the forewing may be 

 either completely pectinately branched, or R.4 + 5 may retain its 

 original dichotomic branching; these two formations are figured 

 in Text-fig. 1, a and b. An analysis of nearly two hundred speci- 

 mens of both sexes shows that about 40 per cent, of the speci- 

 mens have the dichotomic branching of R.t + 5 in both forewings, 

 only 20 per cent, the complete pectinate branching in both, and 

 about 40 per cent, have one forewing with one condition and the 

 other with the other condition. Thus 60 per cent, of the total 

 number of forewings have the dichotomic condition present, and 

 only 40 per cent, the pectinate. The total number of branches 

 descending from lis before the region of the pterostigma varies 

 from three to six. 



Abdomen fuscous above, brown beneath; segs. 1-2 hairy; 

 seg. 1 paler above. Each segment has a pair of oblique pale 

 marks dorsally, placed well apart on either side of the middle 

 line, and laterally a pale curved band. 



Appendages pale brownish; the superior in the form of a 

 pair of strong forceps about 2 - 4mm. long, of moderate width 

 viewed dorsally or ventrally, but much wider when viewed later- 

 ally (see Text-fig. 2, so); the inferior a single, broad, valve-like 

 hypandrium (Text fig. 2, hy) lying beneath the penis, whose hard, 

 brown, chitinous hooks or penunci (Text-fig. 2, d, pu) can be seen 

 above its base. The anus lies on the reduced tenth segment or 

 proctiger, midway between the two superior appendages (Text-fig. 

 2, d, an) (See also Crampton, 3, fig. 14).
