66 STUDIES IN AUSTRALIAN NEUROPTERA, ii., 



covering only the lower portions of four veinlets. Before origin 

 of Rs, in radial space, seven cross-veins in fore, five in hindwing. 

 In both wings, five branches of Rs before radial brace. 



//rt6.— Broken Hill, N.S.W., collected by Mr. O. Lower, to 

 whom I dedicate the species. Jiourke, N.S.W., collected by the 

 late Mr. Helms. Fairly common 



Type in Coll. Tillyard (Broken Hill, undated, O. Lower). 



A very distinct and striking species. 



Genus A c a n t h a c L i s i s Ramb. 



18. ACANTHACLISIS PETERSEN!, n.sp. (PI. i., fig. 2). 



Total length 45, abdomen 31, forewing 66'5, hindwing 62'5nim. 



Head: eyes brown; occiput greyish black; mttennce. 10 mm, 

 black, very slightly clubbed; epicraninm and face dark grey, 

 Iiairy; labrum and mouth-parts rich brown, labium fulvous. 



T bora X : prothorax short, tapering towards head, grey-black 

 above, brown on sides. Fterothorax brownish, with grey shading, 

 and long, soft, grey hairs; underside covered with thick, pale 

 grey hairs. Legs short; femora brown: those of forelegs very 

 hairy; tibife brown, those of fore and middle-legs touched with 

 black on ba.sal half: tarsi very short, 1-4 blackish, 5 pale, with 

 deep apex and claws. 



Abdomen cylindrical, with close-set, small, black hairs, 1-2 

 and apex with longer hairs; colour black, with irregular, brown 

 patcties on either side of middle line on segment 3 (very slight) 

 and segments 4-7. 



VV i II gs wide, fairly well jjointed; i^enatioti, in general. Ijrown, 

 C, 8c, and R tinged with orange; Cu, -|- M.^ in forewing strongly 

 marked with black A pale ochreous area on pferostiyma of all 

 four wings. Forewings strongly speckled all over, due to all the 

 veins being irregularly marked with black. Jn radial space, 

 before origin of Rs, eight cross-veins in fore, six in hindwing. 

 In forewing, Cu.^ diverges very strongly from Cui-f-Mo; the 

 oblique vein is black, 3-4 cells' length distad from the cubital 

 fork. Cubital space in forewing wide, triangular, with four, 

 single cells, then two together, then three at widest part, and, 

 finally, three single cells at distal end.
