IVI a 1 e (Fig. 33). Length 380 (x without mandibles and 

 abdominal lobes, 504 !^ with these organs. Colour brown. 

 Shape like PterolicJms totani^ etc., but abdominal incision quite 

 otherwisse. This excavation (Fig. 35) is longer than wide ; its 

 anterior third part is an oval »couchant« ; its posterior third 

 a bee-hive without top; its membrane is not so thin and trans- 

 parent, but a distinct thinning of the abdomen itself; this 

 membrane is equal of width everywhere, and lengthens in the 

 postcornal threelobed pieces ; the three lobes are triangles. 

 Texture smooth on the shields ; wrinkled in the soft parts. 



Dorsal side (Fig. 33). The margin of the pro- 

 soma is well chitinized and dark-coloured. The space within 

 this margin is occupied by the anterior dorsal shield, except 

 behind the trochanteres 11. Behind these trochanteres and the 

 anterior shield there is a wide band of unprotected skin. Then 

 follow the posterior dorsal shield and the two lateral shields 

 which are separate by a rather narrow band of unprotected 

 skin. Also behind the lateral shields there is a long triangle 

 of soft skin. The nephridial openings are on a line 

 with the femora IV. Hairs. On the anterior dorsal shield 

 near the trochanteres II a pair of long hairs, nearly as long 

 as the width of the shield. Inside of these long hairs a pair 

 of minute ones. On the lateral shields a pair of minute hairs 

 near the anterior edges, and quite laterally (therefore I have 

 delineated this hair also on the drawing representing the ven- 

 tral side of the creature) the long lateral hair, as long as the 

 shields themselves. On the posterior dorsal shield a pair of 

 minute hairs near the anterior edge ; a second pah" more 

 backward and more outward, on a line with trochanteres III;
