WARBURTON— THE ACARINA OF THE SEYCHELLES 357 



29. Neoleodes striatus, n. sp. (PI. 19, fig. 23). 



Smaller and more elongate than N. rugosus. 



Length about "9 mm. 



Cephalothorax long, the transverse line very anterior, the anterior portion not half 

 the length of the posterior. Both regions pitted, the posterior more coarsely. Pseudo- 

 stigmata large, far apart, white rimmed ; pseudostlgmatic organs short black rods with 

 oval white head (fig. 23 a). Abdomen elongate, widest near the posterior end, with 

 a short, blunt, caudal process arising from a raised pitted oval area. The anterior median 

 field Is deeply pitted and exhibits a few longitudinal striae, while the posterior lateral 

 fields have strong transverse or radiating strise. Legs much like those of N. rugosus. 



Four specimens, Praslin, Cotes d'Or Estate. 



30. Neoleodes femoralis (PI. 19, fig. 24). 

 Small, with pronounced caudal process. 

 Length about '5 mm. 



Cephalothorax broad and blunt, the transverse line anterior. Anterior (rostral) 

 region pitted, as Is also the posterior region except on triangular white areas in front of 

 the pseudostigmata. Pseudostigmata near together ; pseudostlgmatic organs stout white 

 spikes with black points. Femur of leg I broadened distally and produced Into an 

 iufero-external spur. 



One specimen (mounted on card) bearing two cast skins, Cascade Estate, Mahe. 



31. Nothrus seychellensis, n. sp. (PL 18, fig. 18). 

 Length about "75 mm. 



Cephalothorax long, punctate, with rather blunt rostrum. Rostral hairs thick, 

 white, clavate. Pseudostigmata far apart ; pseudostlgmatic organs long, stralo-ht, rio-ld. 

 Abdomen elongate, rounded posteriorly, punctate, the dorsum concave immediately within 

 the periphery but raised again In a median longitudinal convex area ; about five pairs of 

 short clavate hairs in two longitudinal rows on the convex median region, and four on 

 either side of the body. The rounded posterior end with four terminal and two sub- 

 terminal (more dorsal) clavate hairs. Legs moderately long and strong, tridactyle. 



Apparently a common species In moss, Mt Alphonse, Mt Sebert, and under stones. 



32. Nothrus tectorum var longipes, n. var. 



In size and appearance much like N. tectorum but on close examination its texture Is 

 seen to be coarser and Its legs somewhat longer. The pseudostigmata are farther apart, 

 and the pseudostlgmatic organs are long, very slender stems with slightly thickened, 

 black tip. The dark lateral patches on the abdomen are present, and there are some 

 clavate hairs at the posterior end, though (at all events in the mounted specunens) the 

 dorsal hairs are not visible. 



Fairly common In moss from Palm Valley, Praslin.
