This spider may be roadily known from Misumena vatia, Clk. 

 (p. 290), by its larger size and darker colours. The tubercle, 

 behind which the hind lateral oyo is placed, is larger, of a 

 rather difforont shape, and gives a more angular form to the 

 fore part of the caput. The abdomen is broader than long ; the 

 hinder part, on the upper side, is at least double the width of the 

 fore extremity ; it is also more prominent and conical at the outer 

 corners of the hinder part than in Misumena vatia. The hinder 

 slope is long, and extremely abrupt ; it is of a dull yollowish- 

 brown hue, more or less spotted with whitish, and with several 

 broad, irregular, transverse, whitish, slightly angular, or curved 

 bands. The cephalo-thorax is dark, yellow-brown, mottled with 

 pale brownish-yellow, forming a broad, but not well defined , 

 band along the middle, and with a yellowish-whito margin 

 The legs of the two first pairs are dark yellowish-brown, spotted 

 with dull yellowish ; the tibise and metatarsi being banded with 

 yellow-white. The third pair are of a uniform yellowish hue ; 

 the fourth pair are similar, with the genual joints and fore 

 extremities of the tibice dark reddish yellow-brown.
