copulating organ (fig. 5), which has a dilated extremity of 
the shape of an arrow-head, with a duct running through its

The legs are thick and short, the femora very thick and 
rounded ; the first pair are shorter than the other two, and 
have two spines at the distal extremity of their ¢ibie ; on the 
under margins of the ¢ibie of the intermediate and posterior 
pair of legs are seven or eight tufts of sete, bent backwards. 
Genus Docornorvs, Nitzsch,* Denny. 
Body broad. Head very large, temples rounded; two movable 
trabecule in front of the antennz, which are alike in both sexes. 
The last segment of the abdomen is entire and rounded in the 
male They live on all birds except Galline and Columbe. 
Docophorus mandarinus, Giglioli, sp. nov. (Pl. 13, fig. 9).— 
This small and curious species inhabits the Chinese blackbird, 
Merula mandarina. Its length is about ;,th of an inch; 
its body has the shape of a flask, the head being the 
stopper; it is of a light-brown colour. 
The head is enormous, triangular, produced anteriorly into 
a broad truncated snout, with a large space divided off by a 
narrow white line. Trabecule large and rather obtuse. 
Antenne straight, composed of five cylindroid joints, the 
basal one being the largest. Posterior angles of the head 
large and rounded, with a few divergent hairs on the edge; 
occipital line sinuous. Mandibules thick and bifid. 
Thorax about half as long as the head; it widens gradually 
downwards, but is always narrower than the head. The 
prothoraz is very narrow, the metathorax is wider, but both 
are very short, and, were it not for the legs, would be con- 
founded with the abdominal segments; the metathorax, as 
these, has a transverse line of long setz on its inferior 
margin. 
The abdomen is divided into eight segments, the last being 
cleft in the female. I possess no male. 
Legs short and thick, especially the first pair, which are- 
evidently scansorial; the femora are broad and convex 
externally; the ¢idie are short and thick, with spines at their 
distal extremities; the tarsi are rudimentary, and terminate 
in two claws. 
Genus Nirmvs, Nitzsch.t
