SPIDERS FROM SOUTH ANNAM. 307" 



Menemerus crassus, sp. n. 



Female. Cephalothorax black- brown ; a rather large yellow- 

 brown spot surrounds the fovea just behind the line of the rear 

 eyes, and is continued as a narrow streak to the rear slope. Down- 

 lying lanceolate red and white hairs cover tlie upper part of the 

 cephalothoi-ax ; a white fillet round the margin and only red 

 hairs round the front ej^es and on the clypeus ; above the front 

 row of eyes is a row of long brown bristles, and a thick bush of 

 long yellow-grey bristles protrudes from the lower part of the 

 clypeus and base of the mandibles, the latter being dark red- 

 brown. The lip and maxillfe are yellow-brown with yellowish 

 grey fringes. The sternum is brighter, with long upstanding 

 bristles round the ma,rgin. It is twice as long as broad, and 

 does not extend between the rear coxse. 



The legs are bright yellow-brown on the under side, neai-ly 

 black-brown on the upper, with the exception of the tarsi which 

 are yellow- brown. The claw-tufts are grey. Both they and the 

 palpi are closely covered with short red and white lanceolate 

 hairs, and on the tibial and distal joints of the latter are long 

 outstanding yellow-grey bristles. 



The abdomen above is pale yellow-brown, with similar hair to 

 that on the cephalotlioiax but white only round the base, where 

 there is also a band of long white bristles. 



The under side is similarly coloured, but the hair-covering is 

 yellowish grey intermixed with brown bristles on roots. The 

 epigyne is brown, and the spinnerets on the upper side aie 

 covered with red and white hair.

There is one female from the same locality as M. felix, but it 

 is a good deal larger, the abdomen is more elliptical, and the 

 long bunches of bristles on the palpi and fore part of the cephalo- 

 thorax form a special feature.

Male. Cephalothorax black-brown in front and at the sides of 

 the cephalic part, red-brown in the middle and on the thoracic.
