INSECTA. 295 
Scolopendra L. (exclusive of several species). Superior scutes 
plane, 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- 
tenne with 17—20 joimts. Eyes four on both sides, at the margin 
of the head behind the base of the antenne. 
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 Z%dschr. voor nat. Gesch. en Physiol. v. bl. 332—327. Pl. vt.)

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 Koruar under this 
name (Brasilien’s ldstige Insecten, Reise im innern v. Brasilien von DR 
Pout, Wien, 1832, 4to, fig. 4) ought apparently to be referred to Scolopen- 
dra subspinipes GERY. 
Cryptops LrAcH. ‘Twenty-one pairs of feet behind the cheliform 
feet. Eyes none. Antenne with 17 moniliform joints. 
Sp. Cryptops Savignii Lracu, Scol. germanica Panzer u. HERRICH 
ScH#FFER, Deutschl. Ins. Heft 142, No. 2, &c. The species of this genus 
are distinguished, besides the absence of eyes, also by their much smaller 
size from those of the former}. 
Geophilus Leacu. Pairs of feet numerous, 40 and more. Body 
linear. Eyes none, antenne with 14 joints.
