igiQ-] F- C. Fraser : Odonate larvae and exuviae. 465 



5 long setae on the inner surface, a robust, moveable hook and a 

 shorter, robust, terminal spine (pi. xxxvii, fig. 6). 



Head large, eyes globular, projecting laterally, prothorax 

 small, thorax angular, its shoulders projecting, its dorsum triangu- 

 lar, wing sheaths flat and elongated. 



Abdomen short, each segment spined laterally. 



Caudal appendages highly differentiated, 3 in number, all 

 lying in the vertical plane, petiolated and nodate, the petioles 

 spined laterally, terminal part expanding like a leaf, its edges 

 deeply dentate. Peppered with brownish pigment. 



tegs long and slim, barred with pigment, minutely spined. 



Hah. — Found in shallow brooks, in dense, darkened jungle, 

 clinging to pieces of dead twig or tree roots. When not dis- 

 turbed, they stand well out from the resting place, with the abdo- 

 men curled well over the back and the large, caudal appendages 

 waving freely in the current. When disturbed they swiftly crouch 

 flush with the root or twig on which they happen to be. The 

 abdomen and caudal appendages are lowered and if the insect be 

 approached, it will continually manoeuvre so as to place the root 

 or twig between itself and the point of danger.

 Kemp, 3 larvae, 1316/H2. 



Length 17 mm. 



Mask typically Agrionine in shape, somewhat similar to the 

 last but the base not tapering so markedly and there are only 9 

 spines on the outer border. On the inner surface, a row of setae 

 4 in number, placed rather far back on each side of the middle 

 line ; mid lobe similar to the last ; lateral lobe with 7 setae no 

 spines on the outer surface, moveable hook robust. Biting edges 

 of lobes finely crenulate (pi. xxxvii, fig. 5). 



Legs long and slim, bearing 4 rows of fine spines. 



Abdomen cylindrical, strongly spined laterally. 



Caudal appendages 3 in number, broadly sagittate, subnodate, 

 the position of node only indicated by extent of a row of spines 

 bordering the outer side of the petiole, tracheae branching root- 

 like from the main stem. 



Appendages banded with 4 rows of pigment. 



Hah. — Running streams. 



Subfamily PROTON EURINAE.
