THE MYRIAPODA OF NORTH AMERICA. 



individuals which have recently cast off their exuviae 1 The eye-patches arc somewhat 

 parabolic. The joints of the antennae are obconical, dark colored, and tipped with white. 

 The lateral processes are small. The grooving of the scuta is in some specimens some- 

 what obsolete on the dorsum. The posterior scutum is light colored. I have never 

 identified a male. Length, h to i of an inch.

I. STIOMATOSUS. 



" Body brownish, with an impressed dorsal line, impressed white dots and spots ; ulti- 

 mate segments unarmed. 



" Body cylindrical, emarginate, above dark brown, glabrous, an obsolete, dorsal, whitish, 

 slightly impressed, acute line ; segments each with a white dot on either side above, and 

 a larger transversely oblong lateral one, which is gradually more completely bisected on 

 the posterior segments into two distinct dots, which on the terminal segments resemble the 

 dorsal ones ; ultimate one abruptly narrower than the preceding and truncated ; anterior 

 segments attenuated to the head, which is wider than the anterior one ; anterior segment 

 as long as the second and third ones conjointly ; spiracles somewhat prominent ; eyes very 

 distinctly granulated, subtriangular, black ; head dark brown ; labrum white."

I. MINUTUS. 



" Body with a lateral scries of black dots, terminal segments unarmed." 

 " Body cylindrical, emarginate, above pale, obsoletely reticulate, and varied with red- 

 dish ; a lateral series of large black spots, numerous longitudinal impressed acute lines 

 beneath the stigmata becoming gradually shorter to the origin of the feet, beneath whitish ; 

 head white beneath the antennae ; antennae two joints preceding the last, somewhat dilated, 

 not attenuated at their bases, nor separated by a contraction; eyes black, longitudinally 

 sublimate ; ultimate segments unarmed longer than the penultimate one, rounded at tip 

 and blackish. Length nearly half an inch. Common on the Lastern Shore of Virginia."
