220 Prof. J. Wood-Mason on two new 



Subgenus 2. Pakadanuria, nov. 



Eyes armed with a conical spine entirely surrounded by the 

 faceted corneal membrane. Legs : the anterior ones long and 

 slender, femora furnished with spines along their apical three 

 fourths ; tibife long and very slender, spincd on the apical 

 half of their length (5 spines on the outer, 11 on the inner 

 edge) ; the four posterior ones very short, their femora strongly 

 trifurcate at the apex, prismatic, their crested angles spinulose 

 and furnished (the inner and lower ones) with triangular 

 foliaceous lobes. Sup raanal plate broader than long, triangu- 

 lar or short shield-shaped. Cerci foliaceous. Organs of 

 flight'} Otherwise as in Danuria [q. g. D anuria Thunhergi), 

 all the known species of which are African. 



Paradanuria orientaUs, sp. nov. 



$ (nymph). Stone-coloured. Body greatly elongated, 

 linear. Head horizontal, higher, or rather longer than broad; 

 forehead and face in the same plane, the former with a large 

 tubercle in the middle and with anotlier minute one between 

 this and the ocelli ; ocular lobes of the vertex armed each with 

 an obtuse tubercle representing the well-developed auricles of 

 D. Thunhergi^ the line of the vertex between these tubercles 

 slightly concave ; facial shield with its upper or posterior 

 margin more produced in the middle than in the species men- 

 tioned. Eyes each with a conical spine, directed outwards and 

 slightly backwards, at their upper and outer angles. 



Organs of flight not yet developed, but probably much 

 abbreviated in the perfect insect. 



Prothorax apparently much as in D. Thmibergi^ both in 

 shape and ornamentation, but longitudinally deeply grooved 

 on each side next to the lateral margins, and proportionally 

 longer in the neck. Mesonotum and metanotum also longitu- 

 dinally carinate. Abdomen linear, longitudinally carinate 

 above, the keel and the sharp projecting points into which it 

 is produced at the middle of the hinder border of each segment 

 (including the supraanal plate) increasing in strength and 

 size towards the apex ; supraanal plate triangular or short 

 shield-shaped, its lateral margins being arcuate. Cerci folia- 

 ceous, as long as the four terminal dorsal abdominal segments 

 taken together, spatulate in outline as seen from the side, 

 granulose, divided at the extremity into two rounded points 

 by a broad but shallow notch, their upper edge thin, sharp, 

 and exarticulate, their lowxr edge thick, transversely convex, 

 and obscurely segmented. 



Anterior legs long and slender j coxee as in B. Thunhergi-j
