1905. May. 1. Ingrassia veligera Oudemans in Entomologi- 
sche Berichten, n°. 23, p. 224. 
Nympha (I1?). (Fig. 46—47). Length 330 2. Colour 
pale yellow. Shape elongate; almost equal wide between 
legs II and II, then diminishing in width till behind legs 
IV. Abdomen bilobate with shallow triangular incision. Tex- 
ture smooth in the shields; finely wrinkled in the soft skin. 
Dorsal side (Fig. 46). Anterior dorsal shield as 
narrow as the tibia I, gradually becoming slightly wider poster- 
iorly, where it is pointed. No posterior dorsal shield. Anterior 
lateral shield (behind legs II) with posterior edge running 
obliquely forward and inward, even somewhat concave. Middle 
lateral shield narrow, simulating dorsal coxal plate III. Pos- 
terior lateral shield ditto. Hairs. To the sides of the pos- 
terior end of the anterior shield the pair of long hairs, longer 
than the width of the body. Inside of these the pair of short 
and thin accompanying hairs. On a line with the posterior ends 
of anterior lateral shields, much more outward, but not near 
the edge of the body, a second pair of long hairs, as long as 
the width of the body. On a line with trochanteres III, more 
inward, a third pair of hairs, shorter than the width of the body. 
On a line with the posterior ends of genu IV a pair of still 
shorter hairs a little more outward ; finally on the lateral side 
of the abdominal lobes a pair of hairs as long as the width 
of the abdomen and outside of them a minute hair. 
Ventral side (Fig. 47). Epimera I united to form 
a sternum; the trunk of the Y is as long as its branches. 
Epimera II slightly longer than the trunk of the Y. Epimera 
III only represented by a very short chitinous bar quite on 
the edge of the abdomen. Epimera IV very short, partly on 
the edge of the abdomen, partly springing inward. Shields 
absent. Anus terminal. Hairs: a pair of short and thin 
hairs between epimera I and Il; a pair of ditto before the 
proximal ends of epimera IV ; a pair of long hairs, as long
