Male. — Color blackish red, with half the breadth of e^ch 

 segment towards belly reddish ; feet red ; lasi segment with a 

 strong recurved mucrone, which, and the anal flaps, are brown- 

 ish red. In some the whole anterior cd^e of segments, are 

 reddish. 



Female. — Color greenish with some reddish brown rariega- 

 tions on bick and sides; mucrone yellowish. In some the back 

 is du*sky green, with the exception of two rows of reddish biown. 

 spots. 



Note.— Juius dorsatis is readily distinguished from the other species 

 by its black dorsal line and by the partial row of minute-circular de- 

 pressions on each side. — Juius crylhronolu* by its great lungi'b when. 

 compared with its thickness, by its very short and delicate feet, and? 

 by the anal flaps being terminated, each, by a small mucrone. —Julus 

 titiatut is characterised by the colors being disposed in .somewhat cir- 

 cular rings, and by the striae on the lower and hinder parts of each 

 segment. This species rolls itself up very slowly, and never continues 

 long in that stale. — Juius Cuhaa is distinguished from the last, to which 

 ■It \i most closely allied, by its not having the colors of the feet disposed 

 in alternate rings.— Juius erythromelas by its strong mjcrunc. and by 

 its being thicker in proportion to its length than any of th; yet known 

 South African species.
