Fam. Attid^. 

 Gen. Makpissa, C. K. 

 Marpissa armifera, sp. nov. 



Mas. — Ceph.-th., long, 2; broad, 1-2. Abd., long, 2; 

 broad, 1-2. Legs, 1, 4, 2, 3 ; 1st and 4th about 3-5 mm. 



Cephalothorax mahogany-colour, fuscous clouds, bluish 

 reflections ; moderately clothed with whitish and orange-red 

 hairs ; clypeus fringe thick, projects well over falces ; cephalic 

 part aplanate, limited by an oval fovea, sensibly compressed 

 forwards, lateral margins retreating ; height of clypeiis equal 

 to diameter of a lateral eye ; thoracic part very slightly 

 dilated, barely one-third longer than cephalic ; profile-line 

 ascends from thoracic junction at an angle of 60°, somewhat 

 level over occiput, inclined across eye-region. 



Anterior row of eyes perceptibly recurved, median pair 

 subtouching, laterals removed from them by an interval 

 visibly shorter than their own radius ; dorsal eyes scarcely 

 surpass laterals in size, interval separating them slightly 

 exceeds space dividing the latter pair ; posterior eyes about 

 one-third further from each other than they are from lateral 

 border ; eyes of second row nearly intermediate between fore- 

 and hind-eyes. 



Falces red-mahogany, clouded ; perceptibly shorter, and 

 less stout, than the pars patellaris of first leg, retreating. 



MaxillcB yellowish-mahogany ; elliptic-spathulate, inclined 

 towards labium, which is oval, base dark. 



Stermim brownish ; haired ; oval. 



Legs, thighs suffused with black-brown ; patellaB of first 

 and second yellow-mahogany ; tibige fuscous ; metatarsi and 

 tarsi yellowish ; second half of former article dark-brown ; 

 patellary and tibial joints of third and fourth legs brownish- 

 yellow, broad distal fuscous annuli ; metatarsi and tarsi yel- 

 lowish, fore-half of penultimate joint fuscous ; spine armature 

 does not differ materially from female's. 



Palpi yellowish-mahogany ; pars humeralis subcylindrical, 

 scarcely surpasses clava in length ; cubital joint yellowish, of 

 somewhat even breadth, nearly one-third longer than radial; 

 latter article projects from outer side a strong process, curving 

 forwards and inwards ; lamina ovate, apex abscinded ; 

 sparingly haired ; genital bulb greenish tone ; viewed from 

 beneath, subcordate, depressed, base incised prominently, 

 especially on outer side ; projecting between bulb and lamina, 

 inner side, is a plainly visible membranous process, sharply 

 compressed into a dark spine-like apex. 



Abdomen ovate ; hairs white and orange-red, somewhat 

 sparse ; specific pattern resembles that of the more obscurely- 

 marked female.
