210 The Barao do Castello de Paiva on two new Species 



Male. About an inch long. Cephalic horns large, two-jointed ; 

 basal joint stout, of considerable length, and (as seen by a power 

 of f rds of an inch) roughened all over with very short sharp 

 prickles ; terminal joint shorter, and bent in form of a hook. 

 Antennae rather long, terminated by two or three short setae. 

 Sessile eye small, somewhat lunate-shaped; compound eyes 

 rather large and pedicelled. Mandibles largely developed. Cau- 

 dal portion of body formed of seven segments. Male organ 

 largely developed, composed of two portions : the basal portion 

 having a strong tooth on its inner edge; the terminal portion 

 straighter, and terminating in a flattened point with some toothed 

 appendages attached to it. 



Female. Cephalic horns much shorter than in the male, and 

 consisting of only one joint. The basal portion is broad and 

 flat; the terminal portion suddenly becoming narrow, and ending 

 in a sharp point. Antennae rather shorter than in the male. 



In other respects the two sexes are nearly alike, except that 

 the female is about a fifth smaller. Ovarian sac cylindrical and 

 of considerable length. Eggs of an orange colour. 



Hab. Pool of Gihon, Jerusalem.
