band of skin between the anterior and posterior shields. 

 Posterior incision almost triangulär with rounded top. 

 So called h o r n s or abdominal pieces almost triangulär with 

 somewhat convex edges. Hairs: No vertical hairs. The 

 two anterior hairs are planted on the wing-like widenings of the 

 anterior shield, behind trochanteres II, and are about as long as 

 legs II. The posterior abdominal hairs were wanting , but the 

 species is sufficiently c ha r a c t er i s e d by the 

 wing-like widenings of the anterior shield be- 

 hindlegsll. 



Ventral side (fig. 27). E p i m e r a I joined to a sternum 

 reaching a line which goes through the proximal ends of 

 trochanteres IL Epimera II slightly longer than epimera I nearly 

 reaching the epigynium. Epimera III more or less L-shaped, 

 Short, and touching with the angle of the L the lateral edge of 

 the body. Epimera IV nearly accolade - shaped , long. Between 

 legs II and III an L-shaped chitinous bar , which apparently is 

 a ventral continuation of the anterior lateral shield. Between 

 this chitinization and epimera III there is a very narrow triangle 

 of unprotected skin on which a distinct scar of a hair fallen 

 out ; probably this is the accompanying hair or little pin ; the 

 longer one, which is very short in this species is planted on the 

 angle of the L-shaped epimera III. A pair of minute hairs inside 

 of epimera II, a pair of dito inside of epimera III , on the edge 

 of coxal plate III. Shields: Outside of epimera I and II the 

 narrow triangulär coxal plates ; inside of epimera III and IV the 

 coxal plates III and IV. Moreover a distinct almost oval or 

 elliptical anal plate surrounding the anus and the abdominal 

 incision. Epigynium somewhat crescent - shaped but with 

 -distinctly widened horns. 



Mandibles usual, small (fig. 26). 



Maxillae usual (fig. 27), small (the head is compara- 

 tively small). 



Legs Short (fig. 26) with only 4 free joints. The trochanteres 

 I and II Short , triangulär ; the trochanteres III and IV distinct 

 on the ventral side (fig. 27), triangulär. Femorigenu I and II 

 Wide and dorsally provided with ä comparatively enormous dorsal 

 and inward elbow. Tibia and tarsi long. 



H a b i t a t : Gambetta flavipes and Totanus calidris. 



Patria: Probably the geographical distribution of the 

 species is the same as those of the birds.
