In M. kirsuta $ the legs of the l:st pair are 3 times as long as 

 the cephalothorax, which is brownish yellow, marbled with white; 

 its back is not carinated; the pars cephalica is large and well de- 

 fined, with slightly rounded sides, strongly depressed across the 

 middle, and has above some longitudinal whitish stripes alternating 

 with brownish yellow stripes. The cf of M. kirsuta is unknown to me. 

 The anterior lateral eyes are not inconsiderably larger than the an- 

 terior centre eyes, and both this peculiarity and the strong spines 

 on the under side of the tibiae and metatarsi of the anterior legs 

 mark this species as standing on the limit of transition to the genus 

 Xystieus. As in M. villosa, the posterior centre eyes are of equal 

 size with the posterior lateral eyes, and the area of the four centre 

 eyes rectangular, or at least not narrower before than behind.
