DiNOPIS ASPECTANS, Sp. D. 



5 . Colour. Carapace yellowish brown, covered with whitish hairs, 

 reddish hairs around the eyes ; mandibles pale yellow, sparsely 

 speckled with black, scantily clothed with yellow hairs : mouth - 

 parts yellow ; sternum yellow, blackish at the sides, mottled with 

 yellow and white hairs ; palpi yellowish brown, mottled with black : 

 iegs brownish, femora infuscate distally, the anterior pairs also 

 infuscate beneath and spotted with black at the base of the spines 

 above, patellje fuscous, tibiae distally ijifuscate, 3rd and 4th pairs 

 with superior distal spot, protarsi yellowish indistinctly speckled 

 with black ; abdomen clothed laterally and below with whitish 

 hairs, with four white spots and two parallel lines on the area 

 between the epigastric fold and the cribellum ; the upper surface 

 covered with darker hairs, with a low crest of hairs passing trans- 

 versely in front of the prominences and curving backward on the 

 sides. 



Carapace nearly twice as long as wide, its length equal to that 

 of tibia of 3rd leg, a little more than one third that of the 1st 

 protarsus, less than half (about two fifths) the length of the 1st 

 femur; cephaHc area a little wider in front than behind ; super- 

 ciliary ridges evenly rounded, not prominent or produced into horn 

 or tooth ; the posterior median eyes close together, their radius 

 exceeding the height of the clypeus, anterior medians about two 

 diameters apart. 



Palpi very slightly longer than carapace. 



Legs 1, 2, 3, 4 ; 1st twice as long as 3rd, 1st exceeding the 2nd by 

 half its protarsus and its tarsus ; 3rd reaching to apex of tibia of 2nd 

 when both are extended; on the femora of the 1st and 3rd the 

 anterior spines are supported on tubercles which also support 

 small tufts of hair. 



Abdomen rather more than twice as long as wide, posteriorly 

 pointed and compressed, widest just in front of the middle, where 

 it rises into a pair of prominences, from which it narrows anteriorly 

 and posteriorly. 



Measurements in millimetres. — Total length 19 ; length of cara- 

 pace 7, width 4; length of abdomen 12, width 5; length of 1st 

 leg 58, of 2nd 45, of 3rd 29, of 4th 28. 



Loc. Benito Kiver {G. L. Bates) ; a single 2 example. 



This new species may be at once recognized from D. anchietce 

 (Dinopis anchietce, Brit. Cap. loc. cit. p. 15, pi. ii. figs. 2-2 c), from 

 Eio Quilo, Angola, by the absence of triangular superciliary crests, 

 the greater length of legs, flatter and longer carapace, proximity 

 between posterior median eyes, &c. In D. anchietoi the eyes are 

 concealed by the crests Mhen viewed from above and are nearly a 

 radius apart ; the thoracic portion of the carapace is as wide as 

 long, and although the length of the trunk is about the same as in 

 D. aspectans, the anterior leg measures only 41 mm. instead of 58.
