INJUKtOUS TO fHB TURNIP CHOP. 335' 



All these are members of the family Staphylinida. 18. Helophoru* grandit. 

 \y N. mibilus. 20. Tho blackish larvo) of a species of Teiephorus. 21. 

 Larva of another species of Telephorua, of a pale brown colour, with a 

 line of darker spots along each side of its body, of which tho six anterior 

 are somewhat elliptical. 22. Larvae of a gnat, perhaps of Trichocera 

 regelationis, of which I foand perfect insects issaing from under turnipb. 

 23. Spiny-coated larva of a two- winged fly, similar to that from which 

 Anthomyia eanicularis has been bred, and to another figured by Curiif* 

 in tlie Oardeners* Chronicle, Dec. 6., 1845, p. 817, under the name ot 

 Antfiomt/ia tuberoga. 24. Smooth larvw of another dipterous insect ; appar- 

 ently an Anthomyia. 26. Qamasus coleoptratorum, a kind of mite. 26. 

 Two or three species of Poduro? or spring-tails. 27. A small Annelide, of 

 fretjuent occurrence, under decaying substances, and in rich soils. It 

 evidently belongs to the Lumbrici (earth-worms), and may have been 

 described by Muller, to whose work on Vermes, I have not access. At 

 ri»k of creating a synonyme, I will designate it as 



LuMBRicus PUTBED1N18 .* CuAK. — Filiform, minutely and closely annulate, 

 translucent, whitish, shining ; clitellum (genital-band or ** knot") whitest, 

 placed at one-fifth the length of the body; if absent, tho part where it 

 is situated likewise whitest; the centre of the body, behmd it dusky, 

 occasioned by earth in the intestinal canal ; narrowest towards the tad, 

 which is somewhat blunted; anterior end slightly tapered. Length, about 

 an inch; breadth, half a lino or more. 



When taken out of the soil it wriggles like a Gordius; but while there, 

 its motions are those of the earth-worm, but it is destitute of its agility. 

 It is easily killed, and readily dries up.

 Linear, narrowest towards the head, increasing in breadth posteriorly ; 

 ♦ lie anal segment abruptly smaller ; white, shining. Head moderate, ovate, 

 corneous, with two deepish bent depressions converging behind and in 

 front, and enclosing an ovate elevation ; honey-yellow. Antenna; 5-jointed,

 oblong, its base rather broadest; 2d cylindric, rather narrower than the 

 1st, and about its length, with a narrow elliptical process projecting from its 

 tip internally; 3d one-half narrower, and a little longer than the 2d, 

 subcylindric ; 4th considerably narrower, and a little longer than the 3d, 

 cylindric ; 6th a little narrower than the 4th, elliptical, subacuminate ; 

 the bases of the several joints pale, the tips of a light brown. Mandibles 

 shortish, minutely dentate, leaving a free space at the point. Maxillie 

 rather broad, deeply notched at tlie top, so as to appear strongly bidentate,

 siiierably narrower, cylindric; 3d not longer than the 2d, sub-acum-

 dorsal line passes through the segments, and appears on the 2d and 3<1 

 as a dvepish, often colourless, channel; 2d segment (prothorax) broatier 

 than the head, sub- quadrate, widest behind, dirty whitish in the middle, 

 posterior and anterior margins with an olivaceous or brownish green band, 

 broadest on the latter ; 3d (mesothorax) transverse, a ht tie wider than the
