This species is unknown to me. It is a darker-coloured species 

 than S. flavipes. The type was described from Adelaide, S.A. 



Nymphes myrmelionides, Leach.

This handsome insect has a wide range over New South Wales. 

 I have specimens found in the neighbourhood of Sydney, New- 

 castle and Armidale; also in Southern Queensland. The type 

 was in Mr. Alexander Macleay's Collection, and was recorded 

 from Australia, Mr. McLachlan says there is a fine series in the 

 British Museum. 



Length of body 1 ; expanse of wings 3-J inches. 



General colour reddish-brown, abdomen darker; eyes grey; 

 antennas black, reddish at apex, composed of 72 short rounded 

 joints covered with fine hairs. Wings large, with the extremity 

 of each blotched with an elongate white mark enclosed with 

 brown. 



Larvae were obtained at Armidale about the end of November, 

 hiding among rubbish or clinging to overturned logs, so well 

 €oated with bits of dirt that only the front of the head and 

 mandibles were exposed; until disturbed they remained jDerfectly 

 motionless, but moved quickly when touched. In captivity they 

 took no food, and after remaining for three weeks in a jar three 

 of them pupated, forming typical, rounded, parchment-like, pupal 

 cases. From the situation in which they were found they would 

 probably feed upon wood ants. 



Larva. — Length 8 lines; general colour brown, marked with 

 darker parallel lines on the dorsal surface of the thorax. Head 

 a,rcuate in front, rounded on the sides, with the hind margin 

 forming two rounded lobes attached to the thorax b}^ a slender 

 neck. Jaws longer than head, shaped like a pair of calipers, 

 with slender points and a sharp pointed thorn in the centre of
