This common species is the largest aiul most brightly colored of the 

 genus. It is 2-5'"'" long. The abdomen is bluish black, the cephalo- 

 thorax, femara and palpi, bright orange, and the rest of the legs nearly 

 black. The male has the head very high and slightly bilobed at the 

 top of the hump. The hind middle eyes are nearly at the top and 

 widely sepai-ated. The holes are just above and behind the lateral 

 eyes. Fig. 3a. The male palpi are very large. The tibia has a long, 

 flat hook, pointed at the tip. Figs. 3c?, 3e. The tarsus has a hump on 

 the upper side on which are a few stifi" bristles. The tube is large 

 and stiff and long enough to turn once around the palpal organ. It 

 is supported at the end by a hard, twisted process. Fig. 3e. The 

 head of the female is only slightly elevated gt the back. The epigy- 

 num is large and open in the middle. Fig, 3/! The female is likely 

 to be mistaken for Cornicidaria cmranticeps^ but when full grown is 

 larger and has the abdomen larger and thorax Mdder than the 

 Cornicularia. 



This is a very common spider in Eastern Massachusetts, on bushes 

 in summer, but I have only found the adult male once, in June. 

 Adult females are common through the summer. I have specimens 

 from the White Mountains ; Mt. Tom, Mass. ; Albany, N. Y, ; and 

 New Haven, Conn.

 This resembles florens^ but is smaller and lighter colored. The 

 cephalothorax and legs are yellow, the legs long, as in the male of 

 florens, the abdomen dark gray. The hump of the male is as high as 

 in florens, but the hind middle eyes are lower and closer than in 

 that species and project forward as far as the lower middle pair. 

 The holes in the humj) are turned forward just above the side eyes, 

 and look like an extra })air of eyes. Below the eyes there is a 

 rounded for\vard projection of the head. The ])alpi of the male have 

 a short truncated hook on the tibiic. The tube is long enough to turn 

 once around the palpal organ and is sui)ported by a large twisted 

 appendage, corresponding to the twisted spine of florens. This spe- 

 cies is very near Walckemira hifroiis iilkw., but the patella of the 

 male palpus is longer, and the tibia smaller. The black tooth on the
