INSECTS INJURIOUS TO THE VINE. 139 



numerous. Concerning the land species, 3 he remarks that, if 

 cut into many pieces, each has a forward motion. 



Pliny , b translating this passage of Aristotle on the marine sco- 

 lopendra, says that it resembles the centipede ; and in another 

 part of his work he thus defines the centipede : — " The milli- 

 pede, which is called also centipede, or multipede, is a kind of 

 earth-worm, which uses all its feet, and describes the arc of a 

 circle in walking, and which rolls itself up at the least touch. 

 The Greeks name it oniscon, and sometimes tylon." Farther 

 on, he says, that kind of centipede, which some Greek 

 writers give the name seps, and others scolopendra, is very 

 poisonous: — " Millipeda, ab aliis centipeda aut multipeda 

 dicta, animal e vermibus terrae pilosum, multis pedibus arcuatim 

 repens, tactuque contrahens : se oniscon Grasci vocant, alii 

 tylon. . . . Illam (centipedem) autem quas non arcuatur sepa 

 Graeci vocant, alii scolopendrem minorem perniciosumque." 

 I may remark here, that Pliny, in this place, confounds the 

 julios with another species of millipede, which Aristotle d 

 has mentioned by the name of the polypede of the ass, 

 o?ios a polupos. Pliny appears afterwards to give the name 

 of seps and scolopendra to the onisci, and says they are 

 smaller than the centipede, and that they do not describe 

 curves in walking. But errors of this kind are common in 

 this author. 



Numenius, quoted by Atheneus, calls the julios the entrails 

 of the earth. 



Eustathius, in commenting on this passage, and Theon, a 

 very old author, give different reasons for the expression. 



Hesychius says, the joulos is like the polypede ; that it in- 

 habits moist earth, and differs from the onus, or asellus. 



Lycophron applies the epithet juliopezos to a many-oared 

 ship. 



From all these passages, we may infer, that the jtdos, or 

 julus, was an apterous or wingless insect, with a great number 

 of legs, which rolled up at the touch ; which described curves 

 or sinuosities in walking ; concealed itself in the ground ; is
