INSECTA. 295 



Scolopendra L. (exclusive of several species). Superior scutes 

 >lane, in some subequal, the posterior gradually larger in others 

 (unequal, with larger and smaller almost alternate. More than 15 

 pairs of feet (almost always 21), behind the cheliform feet. An- 

 tennas with 17 20 joints. Eyes four on both sides, at the margin 

 of the head behind the base of the antennas. 



To this genus belong the largest species of this division. In these 

 Myriapoda there are g pairs of air-slits present, in the membraneous part 

 between the dorsal and ventral scutes (in the 3, 5, 8, 10, 12, 14, 16, 18, 

 and 20 ring), above and behind the insertion of the feet, (see my observa- 

 tions in the Tidschr. voor nat. Gesch. en Physiol. v. bl. 332 337. PI. vi.)

 Petropoli, 1834, 4to. The species investigated by this writer is Scolopendra 

 cingularis LATR., which occurs in the south of Europe, in the Crimea and 

 in Egypt. In north and central Europe no species of this genus occur. 

 Formerly many species from different regions were confounded under the 

 name of Scol. morsitans L. ; the species figured by KOLLAR under this 

 name (Brasttieris lastige Insecten, Reise iin innern v. Brasilien von DR 

 POHL, Wien, 1832, 4to, fig. 4) ought apparently to be referred to Scolopen- 

 dra subspinipes GERV. 



Cryptops LEACH. Twenty-one pairs of feet behind the cheliform 

 feet. Eyes none. Antennas with 17 moniliform joints.

 are distinguished, besides the absence of eyes, also by their much smaller 

 size from those of the former 1 . 



GeopJiilus LEACH. Pairs of feet numerous, 40 and more. Body 

 linear. Eyes none, antennas with 14 joints.

1 Here also belongs the genus Scolopendropsis BRANDT, that appears to differ from 

 Cryptopt only by having two segments more.
