setosus of e. L. Koch. The little creature had shrunk, but as I 

 did it swell up, the relative length of the trailing hairs diminished 

 considerably. Yet, with low annplifications the hairs were longer 

 than with high powers (indeed a curious optical illusion). I am 

 sure having drawn -the dragging hairs in my figure not too long, 

 for my drawings are always made with the camera lucida. (N. 

 B. ! Koch draws these hairs three times longer than the body !) 



Male (Fig. 51 and 53). Length 280 ^. — Colour pale straw- 

 coloured. — Shape oval; greatest width behind legs II. — Texture 

 finely granulate like Gl. cadaverum (Schrank). 



Dorsal side (Fig.51). The inner pair of the first transverse row of 4 

 hairs close together, so that their basal chitinous rings touch each 

 other ; the outer pair at a level between legs I and II. — The second 

 transverse row a little behind legs II, straight. — The third row 

 about the middle of the body, well curved forward; the inner pair 

 between median line and edge; the outer pair on the edge. — 

 The fourth row has the shortest hairs; they are shorter than the 

 front-hairs, stiff; the row is well curved forward; the inner 

 pair near the median line; the outer pair close to the edge. — 

 The fifth row considerably curved forward; the inner pair between 

 median line and edge is very long, certainly two times longer 

 than the body ; the outer pair close to the edge, scarcely longer 

 than the body and curved ontward. — The sixth pair slightly curved 

 forward (not backwai'd like in the other species of Gl.^, quite 

 posteriorly ; the outer pair close to the edge about \ \ times longei', 

 the inner pair close to the outer paii', about 2 times longer than 

 the body. — Quite on the posterior edge again a pair of hairs, 

 about 2 tirries longer than the body. 



Ventral side (Fig. 53). Lateral hairs between coxal plates II 

 and III short, about ^ width of body. Five pair of postanal hairs, 

 of which the ist, counted from the anus, minute; the 2d as long 

 as the anus; both pairs smooth; the 3d slightly longer than width 

 of body; the 4th about | width of body; and the 5th about 2 

 times the length of body. — Epiniera I touching each other; no 

 true sternum; epimera II slichtly shorter than I ; epimera III very
