1899.] NEW EXOTIO AIIA.1!TBIDBA. 625 



Phrykarachite fatalis, sp. n. (Plate XXX. fig. 7.) 



Pemale (not quite adult), length 2j lines. 



Ceplmlotliorax short, broad, nearly if not quite as broad as long, 

 slightly roundly -truncate before ; lateral marginal impressions 

 at caput tolerably strong. Height of clypeus less than half that of 

 the facial space. From the ocular area to the beginning of the 

 hinder slope is a tolerably well-defined quadrate, somewhat elevated 

 platform, which terminates at each corner in a strong conical pro- 

 minence. There is also a strong tubercular eminence in the middle 

 of each of the areas formed by the two groups of eyes (the two 

 laterals and the fore and hind central eyes on each side). The sides 

 of the cephalothorax are also covered with lesser tubercles of 

 different sizes. The colour of the cephalothorax is yellow-bi'own, 

 mixed on the clypeus, the sides, aud hinder slope with deep 

 brown. 



The eyes do not differ greatly in size ; they form a wider area 

 than in the typical species. They are in two transverse curved 

 lines whose convexity is directed forwards ; the anterior line is 

 much the shorter, and its curve a little stronger. The central 

 quadrangle is broader than long, aud its anterior side shorter 

 than the posterior. The hind-central pair are smallest, and the fore- 

 laterals largest of the eight. The hind-centrals are slightly farther 

 apart than from the hind-laterals. The fore-centrals are about 

 double as far apart as the fore-laterals. 



Legs very robust, short, 2-1-4-3 ; 2 & 1 and 4 & 3 respectively 

 not very different in length, the former longer and stronger ; 

 tuberculous, especially the fore part of the basal half of the femora ; 

 geuuse strongly angular ; armed with spines, those of the meta- 

 tarsi and tibife of the iirst two pairs much the stronger. Colour 

 pale dull brownish yellow, blotched in parts with wliite and suffused 

 with whitish ; the anterior half of the first aud second pairs black 

 brown. Tarsi end with a small thin claw-tuft. A strong spur in 

 front of each of the femora, used probably, as in P. (Ornithoscaioides) 

 decipiens Porbes-Cambr., for adhering (when on its back) to a leaf 

 for capturing its prey. 



Falces powerful, conical, bx'oad and rather flattened in front ; 

 colour yellowish brown mottled with white. 



Maxillce and labium normal, deep brown in colour ; the former 

 pale at the extremities. 



Sternum oval, broadly hollow-truncate before, and similar in 

 colour to the maxillae and labium. 



Abdomen short, broad, roundly truncate at both ends, but much 

 broader behind, rather flattened above ; covered thickly above and 

 along the sides with tubercles and conical prominences of various 

 sizes ; four of the largest of these latter, of a mottled yellowish- 

 brown colour, form a large central quadrangle whose posterior side 

 is shorter than the rest, the two foremost of the prominences being 

 much the larger ; both before and behind this quadrangle is another 

 pair, nearer together, of much smaller, similarly coloured promi- 

 nences ; on each outer margin towards the hinder part is a con-
