Nymph of Didyophorodelpha.x mirabilis Swezey. 

 December 5, 1907, I obtained an adult and 2 nymphs of this 

 species from the same ridge of Konahnanui on which I first 

 collected 4 adult specimens in February, 1906. (Proc. Haw. 

 Ent. Soc, I, p. 104, 1907). I was unable to determine its food- 

 plant, however, whether it was fern, grass, or sedge, or some- 

 thing else. These being mixed together where I had swept with 

 the net each time when a specimen was obtained. 



Nymph — whitish with pale brown marRIngs on tegminal-pads, 

 sides of thorax and abdomen. A fuscous streak on side of head pro- 

 longation. Legs white, with 2 black spots on dorsal side of tibiae 

 the one nearer base small, the one nearer apex larger, those on pos- 

 terior tibiae smaller than those on the other tibiae; tips of tarsi black, 

 a black spot at apex of basal joint of hind tarsi. Prolongation of 

 head about as long as head and thorax together. 



Two short black-tipped spines on outer side of hind tibiae, one 

 near base, the other a little beyond middle. Calcar of hind tibiae 

 with 6-7 tiny black teeth.
