﻿Sept. 1895] Banks. Acarians from a Sphagnum Swamp. 129 



opening ; coxal plate with two transverse lines ; legs very short, anterior tibia barely 

 longer than the patella, posterior femora very broad and margined below, a curved 

 plate just behind the anterior coxce ; legs most hairy at tips. Differs from O. ar- 

 borea, to which it is allied, by the shape of the wings, in having no superior bristles, 

 the longer setce, small tectal plate, shorter legs, and broad, margined hind femora. 



Many specimens from wet sphagnum, near Roslyn, N. Y. 



Oribata emarginata Bks. 



Several specimens of this species were shaken from the sphagnum; 

 the setje are a little longer than in typical specimens. 



Oribatella setosa, sp. nov. 



Length .48 mm. Red-brown, legs paler, a pale spot at base of abdomen. Body 

 longer than broad, only moderately high ; tectal plate short, the anterior corners 

 free and projecting spine-like, each with a bristle at tip; superior bristles extremely 

 long, erect and prominent, nearly as long as the anterior legs ; sette nearly two-thirds 

 as long as the superior bristles, weakly clavate. Abdomen smooth, broad, evenly 

 convex ; wings quite large, somewhat triangular, the tip broadly rounded, posterior 

 margin very oblique, anterior faintly concave, distinctly longer than deep, hyaline ; 

 venter finely granulate ; genital opening small, about its length in front of the larger 

 anal opening; coxae with the outlines distinct ; legs short, hairy as usual. 



I place this species in Oribatella as the extreme tip of the tectal 

 plate is free and each corner prolonged into a spine ; but the tectal 

 plate is more united to the cephalothorax than in the other species of 

 the genus ; still in Oribata it is wholly united and the corners never ex- 

 tend into spines. It is readily recognized by its long bristles and setae.

Carabodes granulatus, sp. nov. 



Length .4 mm. Black. Cephalothorax granulate, broad, tapering to the trun- 

 cate front, where there are a few simple hairs, a plate-like elevated ridge each side, 

 a median pair of short clavate hairs ; setse a little longer than the hairs and capi- 

 tate. Abdomen roughly granulate, distinctly longer than broad, sides nearly paral- 

 lel, base truncate, tip broadly rounded, with four short capitate hairs on each pos' 

 terior side and four rows above, the submedian with four and the lateral with three 

 hairs ; venter granulate like dorsum ; genital opening about once and a-half its 

 length in front of the slightly larger anal opening ; coxae separate, legs short, femora 

 thickened. 



Related to C. oblonga and to a new species by having the ventral 

 apertures widely separate, and with them should probably form a new 

 genus. It differs from C. oblonga in the shorter body, more coarsely 

 granulate abdomen, and in the clavate hairs. Two specimens shaken 

 from wet sphagnum; Roslyn, N. Y.
