eyes are white hairs growing with their tips toward the 
middle of the clypeus. The abdomen is of a medium brown 
color, much lighter than the cephalo thorax, and shows a few 
white and red hairs. The falses are iridescent green and very 
rugose. The legs and palpi are light brown, the legs having 
the femoral joints darkened. The first leg is darker than the 
others, which show alternate light and dark bands. They all 
have a good many long and short white hairs. 
While this species does not entirely agree with Simon 7 s de¬ 
scription of the genus Margaromma, it closely resembles Key- 
serling’si type, M. funesta. We have one male, from Sarawak.

The cephalothorax is rather high, with the cephalic plate 
nearly level. The thoracic part falls steeply in the female, but 
in the male rounds off in a longer, more gradual slope. It is 
a little wider in the thoracic than in the cephalic part and is 
slightly narrower above than below. The quadrangle of the 
eyes occupies nearly half of the cephalo thorax, is one-third 
wider than long, and is a little wider behind than in front. The 
front eyes are close together in a straight row, the middle be¬ 
ing twice as large as the lateral. The second row is halfway 
between the others. The dorsal eyes stand out prominently 
and form a row about as wide as the cephalothorax. The ster¬ 
num is rounded behind, truncated in front. The first coxae 
are separated by the width of the labium, which is a little 
longer than wide. The clypeus is narrow. The falces are 
vertical and rather long. The lower margin has one tooth, and 
the upper two, one large and one small. The legs are slender. 
The first and second, besides lateral spines, have 3-3 under 
the tibia and 2-2 under the metatarsus.. The spines on the 
posterior legs are very weak. In the male the abdomen is 
strongly constricted behind the middle and is wider behind 
this point than in front of it. The spinnerets are long. 
The coloring is very brilliant. In the male there is a wide
