THE MYRIAPODA OF NORTH AMERICA. 



The color of this species is a very dark, almost black brown ; but the anterior portion 

 of the body, and especially the head, is lighter. The antennae are very pilose, and quite 

 strongly clavate. The eyes are connected tog-ether by a black band. The anterior scuta 

 have their lateral surfaces closely and deeply canaliculate, but are almost smooth on their 

 upper surface. The posterior are everywhere deeply channelled, although more so below 

 than above. There are a few hairs on the anal scales. The anal scutum is not mucro- 

 nate. It affords me pleasure to dedicate this species to Professor Miles, who is laboring 

 so assiduously and successfully to develop the zoology of Michigan.

The color of this species is brown, with a dark, sometimes obsolete ring of blue to each 

 segment, except the most anterior. The lower portion of the anterior surface of the bead 

 is light brown. The labial margin is scarcely emarginate, but is rounded and fringed 

 with rigid hairs. Tin; eyes are arranged in subtriangular patches, with their transverse 

 diameter much the greater. They are connected by a black band, which is much broader 

 in the middle than at the ends. The first scutum is large, with very small lateral pro- 

 cesses even in the female. There is on its anterior edge a very obscure light border, and 

 a little posterior to this a black, more or less obsolete, band. The scuta arc; regularly, 

 although rather lightly and distantly canaliculate over their whole surface. The last 

 scutum is distinctly but minutely punctate, has its edge whitish, and is not at all mucro- 

 nate. The anal scales are not at all pilose. The specimens from which this description 

 is taken are in so bad a condition that I have hesitated to notice them. But probably 

 the description will be found to be sufficiently accurate for the identification of the spe- 

 cies. Length of body about Ik inches.
