infuscatis; abdomine supra sub-olivaceo - fusco, vitta longitudinali 

 albicanti primum ex /\ angustiore, turn /\ latiore, denique ex vitta 

 angusta geminata, quse ex linealis parvis sub-parallelis formatur, com- 

 posita; ventre macula media oblonga flavescenti notata ; procursu in 

 latere exteriore bulbi genitalis apice compresso, rotundato, denticulate 

 — 6 ad. Long. corp. 5 mm. 



Male.— Cephalothorax as long as the tibia and patella of the fourth 

 pair of legs, its breadth greater than the length of tibia of the same 

 pair ; very strongly rounded in the sides of the anterior part of the 

 pars thoracica, less strongly rounded and gradually narrowed back- 

 wards, very suddenly and strongly narrowed anteriorly, with the 

 pars cephalica narrow, not one-third as broad as the pars thoracica; 

 yellowish brown, covered with longish white hair. The tubercle bear- 

 ing the four central eyes very prominent, sloping. Sternum blackish. 

 The line formed by the posterior eyes rather strongly curved back- 

 wards ; the area occupied by the four central eyes broader in front, 

 the fore central eyes separated by an interval at least double as 

 great as their diameter, the interval between the hind central eyes, 

 which are somewhat larger, rather greater than their diameter ; 

 the interval between the central and the lateral eyes about double 

 as great as that between the centrals of the same row. Mandibles 

 straight, brownish, about as thick as the tibise of the first pair. 

 Maxillae brownish, with the interior side of the apex paler. Labium 

 brownish, pale at the apex. Palpi brownish, with the greater part 

 of the genital bulb brownish black. The clava is at least double as 

 broad as the anterior thighs ; the femoral part, when raised, reaches 

 a little higher than the tubercle of the lateral eyes ; the patellar joint 

 is nearly as long as broad, with two long bristles above, at the apex; 

 the tibial joint is about as long as the patellar, gradually broader 

 towards the apex: its outer side is produced into a broad lamellar 

 process gradually dilated towards the broadly truncated extremity, 

 the posterior angle of the extremity being right, the anterior pro- 

 duced and sub-acute; the inner side of the apex of the tibial joint 

 forms a rather prominent angle. The tarsal joint or lamina bulbi 

 turns its convex side inwards, and bears at the base, on the outer 

 side, a blackish brown process curved forwards, which is thick at the 

 base, narrowed towards the apex, which is again somewhat thick- 

 ened, rounded and knob-like. When the palpus is seen from above, 

 the genital bulb exhibits on the outer side a long process, which is at 

 first almost straight and linear, and at the apex compressed into a
