364 Mr. Hugh Scott on certain JVyderibiidse, 



situated dorsally and posteriorly (Fig. 6) : one pair, only 

 separated from one another by a distance = 1 to 2 diameters 

 of the spiracle, quite close to the posterior extremity of 

 the body ; the other pair, separated from one another by 

 a considerable distance, and about ^ 'the length of the 

 body from its hind end. The ventral surface of the larva 

 shows the peculiar configuration mentioned by Speiser 

 (op. cit., p. 27). There is a median area sunk slightly 

 below the level of the surrounding body-surface, with its 

 cuticle much wrinkled and creased longitudinally, the 

 creases continuing in front along the ventral surface of 

 the constricted part of the larva's body. The cuticle of 

 the surrounding body-surface, where it edges on and 

 slightly overhangs the median area, has a different appear- 

 ance, being marked with fine creases radiating from the 

 edge of that area.

Head bare, except for a few short bristles in the middle in front, 

 and along the cheek-margins. Maxillary palpi with very long 

 terminal bristles. Thorax dorsally with a curved row of bristles on 

 either side. Thorax ventrally a little longer than broad, rounded in 

 front, with a brownish middle line somewhat impressed at the ends ; 

 surface of the thorax bearing the usual short bristles, and on its 

 hind margin 4 long ones, of which the two outer are very long. 

 Femora and tibia; (Fig. 13) flattened, each about 2J times as long as 

 its greatest breadth. The femora bare on one surface and bristle-
