One young nympha in alcohol from Yeddo, Japan, by Prof. E. Morse. 

 Length 15 mm. ; breadth 7 mm. 



Body flat, elongate, very hairy ; head large, flat, broader than long, about ob- 

 long, between the antennse a short, broad projection, nearly straight on tip; eyes 

 small, round in the middle of sides ; front angle before eyes conical ; occiput large, 

 straight behind, angles rounded, sides scarcely elevated; antennse short, the two 

 basal joints small, globular, third a little more than twice as long, flattened, bent 

 up, a little dilated externally in middle, more than twice as long as broad ; fourth 

 short, black, conical; jnask large, longer than broad, sides sloping to base, which 

 has half the breadth of the front; middle third a short rounded lobe with a short 

 comb of flat scales and four black short teeth on tip, palpus a flat broad lobe, 

 rounded on tip, inside finely dentate; movable hook long, sharp, arcuate: pro- 

 thorax smaller than head, transverse-oval, side angles rounded ; wing cases reach- 

 ing nearly apex of third segment; abdomen very little elevated above, half as 

 long as broad, oblong, the 9th segment tapering suddenly; segments of equal 

 length, 9th a little shorter in middle; 10th very short, inserted entirely in a broad 

 deep rounded notch of 9th ; lateral spines sharp on segments 7 to 9, the last one 

 as long as segment 10; no dorsal hooks; venter flat, the two sutures as in H. 

 ir-ews^y/ MS, the middle space a little smaller than the laterals; anal appendages 

 short, twice as long as 10th segment, pyramidal strongly pointed, the laterals less 

 than half as long as the inferiors; legs short, fit for burrowing; middle legs very 

 little more distant than forelegs; the four anteriors with thick, strong, curvate, 

 femora and tibiae, the last ones with a strong external hook on tip; hind legs flat, 

 reaching nearly Sth segment, third joint of tarsi as long as the two basal; legs 

 very hairy, hairs very long. 



This remarkable nympha is young, and some allowance will have to be 

 made for this fact. Nevertheless I have compared it with nymphae of 

 H. hrevistylus of the same size. The legs of H. hrevistylus are running- 

 legs, tip of tibiae without hook, middle legs equally more separated as the 

 forelegs, than the hind legs compared with middle legs ; the hind legs of 

 the youngest nymphae longer than the body. The abdomen of H. 

 nanus? is more oblong; the third joint of antennae less flat, elongate, 

 the fourth conical ; the mask has four black teeth ; the head is somewhat 

 similar, but the sculptures wanting or less finished ; the nympha is very 

 hairy. I do not know H. nanus described after one female ; perhaps the 

 nympha belongs to this species — if it is not a young nympha of Chloro- 

 gomphus.
