Scutigera LAM. Cermatia ILLIG. Feet elongate, especially tlie 

 last. Body behind the head covered with scutes above, the fourth 

 longer than the rest. Eyes two, compound. 



Sp. Scutigera araneoldes auctor. (Scolopendra coleoptrata L.?) DUMER. Cons. 

 gn. PI. 58, fig. 6 ; GUERIN Iconogr., Insect. PI. I. 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. LEON 

 DUFOUR has communicated some anatomical details regarding it in Ann. 

 des Sc. not. II. 1824, pp. 92 98. The compound eyes of Scutigera may 

 be looked on as a special anomaly in this order ; the cornea presents 

 hexangular faettes, as already figured by SAVIGNY, Descr. de VEgypte, 

 Myriapodes, PI. i. 1 



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 PALLAS (July* araneoldes in his Spicilegia Zool. ix. Tab. iv. fig. 

 1 6), ordinarily considered as synonymous with Scutigera araneoldes, is cer- 

 tainly a different species. The figure of PANZER, Deutschl. Insect. Heft 

 50, No. 11, under the name of Scolopendra coleoptrata, however it be still 

 referred to by later writers, has no relation to Scutigera, but appears to 

 represent Lithobius forficatus. 



B. Tarsi short, uniarticulate. Antennae shorter than the body. 



Lithobius LEACH. Superior scutes imbricate, unequal. Fifteen 

 pairs of feet behind the cheliform feet. Antennae with numerous 

 joints, in adults above 40. Two groups of eyes in the external 

 margin of the head behind the antennae, the hindmost eye larger 

 than the rest. 



Sp. Lithobius forficatus, Scolopendra forficata L., GUERIN Icon., Ins. PI. L, 

 fig. 6; PANZER Deutschl. Ins. Heft 50, No. 13, Heft 190, No, 20; com- 

 mon in dunghills, under flower-pots, &c. ; 10 lines long, i^ lines broad. 

 See on its anatomy TREVIRANUS, Verm. Schrift. II. 1817, s. 18 33. Taf. 

 iv vii., LEON DUFOUR, Ann. des Sc. not. n. 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. Serie, Tom. vn. Zool. pp.

Sub-genus Henicops NEWP. 



1 In 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 J^- millim. in diameter.
