British Oribaiidee. By A. D. Michael. 191 



ceplaalothorax, but tins is entirely hidden, in the dorsal view, by 

 thin chitinous plates proceeding from the anterior angles of the 

 notogaster, and which remind one a little of the wing-like expan- 

 sions in Orihafa, but are far less developed than in that genus ; 

 these plates end laterally in obtuse points projecting (on the dorsal 

 level) between the second and third pair of legs. By transmitted 

 light the real sliape of the body is seen very clearly through these 

 expansions. 



This species lives in moss ; Mr. George has found it at Kirton 

 Lindsey, and I have met with it wherever I have searched.

The nymph is pale grey, and is a beautiful object when seen 

 alive under a sufficient amplification. 



The skin is slightly granular; the abdomen appears at first, 

 from the dorsal view, to occupy nearly four-fifths of the entire 

 length, but closer examination shows that the hinder portion of 

 the cephalothorax is included in this measurement. The anterior 

 part of the cephalothorax is narrow and truncated ; it bears a ridge 

 along each side, two lesser ones nearer the median line, and some 

 small transverse wrinkles on the vertex. The stigmata are large and 

 open, but not raised, the stigmatic hairs long, rough, gradually 

 thickened towards the end, which is rounded. 



Legs short and of equal thickness throughout ; fourth joints of 

 first pair overhanging the tarsi as in Eremeus. Trochanters longer 

 than other joints, coxa3 set near the edge of the body. 



The abdomen almost coalesces with the hinder part of the 

 cephalothorax, and the two together form an ellipse nearly twice 

 as long as its greatest breadth ; along the median line runs a raised 

 band which widens where it touches the anterior and posterior 

 margins and where it is crossed by the lateral bands; these 

 are usually four in number, each composed of three or four 

 parallel wrinkles ; they are doubly curved, the most anterior curves 

 forward and outward from the median line to near the lateral 

 margin, the three posterior curve backward and outward. 



Found in same places as the adult. 



I believe the species to be unrecorded, and if so I propose to 

 call it Tegeocranus velatus, from the spotted membrane which 

 covers it.

I have found three or four specimens of this singular s]>ccios on 

 moss at Epping Forest ; Nicolet only found about the samo 

 number in the woods of Satory,
