294. CLASS VIII. 
Scutigera Lam. Cermatia Iuuic. Feet elongate, especially the 
last. Body behind the head covered with scutes above, the fourth 
longer than the rest. Eyes two, compound. 
Sp. Seutigera arancoides auctor. (Scolopendra coleoptrata L.?) Dumér. Cons. 
gén. Pl. 58, fig. 6; Guerin Iconogr., Insect. Pl. 1. fig. 7: this animal has 
15 pairs of long feet, which readily fall off as in gnats and harvest-spiders 
(Phalangia) ; it is found in France and other parts of Europe. Léon 
Durour has communicated some anatomical details regarding it in Ann. 
des Se. nat. 11. 1824, pp. 92—98. The compound eyes of Seutigera may 
be looked on as a special anomaly in this order; the cornea presents 
hexangular fagettes, as already figured by Savieny, Descr. de ’Lyypte, 
Myriapodes, Pl. 1.3 
There are still some other species in the warm regions of the old and 
new world, but they appear to me to be not sufficiently determined. The 
figure of Pauuas (Julus araneoides in his Spicilegia Zool. 1x. Tab. Iv. fig. 
16), ordinarily considered as synonymous with Seutigera araneoides, is cer- 
tainly a ditferent species. The figure of PanzrR, Deutschl. Insect. Heit 
50, No. 12, under the name of Seolopendra coleoptrata, however it be still 
referred to by later writers, has no relation to Scutigera, but appears to 
represent Lithobius foryficatus. 
B. Tarsi short, wniarticulate. Antenne shorter than the body. 
Lithobius LEACH. Superior scutes imbricate, unequal. Fifteen 
pairs of feet behind the cheliform feet. Antenne with numerous 
joints, in adults above 40. ‘Two groups of eyes m the external 
margin of the head behind the antenne, the hindmost eye larger 
than the rest. 
Sp. Lithobius forficatus, Scolopendra forjicata L., GuiRIN Icon., Ins. Pl. 1, 
fig. 6; Panzer Deutschl. Ins. Heft 50, No. 13, Heft 190, No. 20; com- 
mon in dunghills, under flower-pots, &c.; 10 lines long, 13 lines broad. 
See on its anatomy TReviranus, Verm. Schrift. 11. 1817, s. 18—33. Taf. 
1v—vil., Lion Durour, Ann. des Se. nat. 11. pp. 81—91. It has seven 
pairs of stigmata. Here also in young animals the number of rings of the 
body and of the feet is smaller ; the augmentation, as the animal grows, 
appears to occur in a manner different from that in Julus, so that new 
segments and new feet appear not behind, but between those already 
formed ; and thus it is explained that the smaller dorsal shields are between 
the larger, GERVAIS, Ann. des Sc. nat., sec. Série, Tom. vil. Zool. pp.

Sub-genus Henicops Nrwpr. 
1 Tn a species still unnamed from Japan in the Leyden Museum, two Paris inches 
in length, (the European species attains a length of only 8 or 10 lines), I found these 
fagettes 1. millim. in diameter.
