492 Insecta Myriajwda found in Berwickshire. 



multiarticulate, long, setaceous, covered with short patent 

 hairs, the two basal joints stout and longer than the third, 

 the following subequal, moniliform : mandibles very strong, 

 5-jointed, the basal one large, the three next short, the claw 

 long, curved, acute, blackish brown : palpi filiform, yellowish 

 brown, hispid, 4-jointed, the joints subequal, the terminal 

 pointed with a minute claw : under lip a broad plate, divided 

 longitudinally into two equal pieces, emarginate, the margin 

 finely denticulated, either smooth or sparingly hispid, with 

 scattered indistinct punctures anteriorly, yellowish brown, 

 with a raised dark rim in front : larger segments of the body 

 chestnut- brown, quadrangular, smooth, margined, the poste- 

 rior margin slightly sinuated, the terminal one narrow and 

 truncate: smaller segments transverse, a shade lighter in 

 colour, produced at the posterior angles : legs 15 pairs, insens- 

 ibly but gradually increasing in length as we count back- 

 wards, the posterior pair disproportionally elongate, tapered, 

 of a uniform yellowish brown, sometimes very pale, hispid, 

 more especially the outer articulations, and armed at the 

 joints with a few spines, the claws acute, dark brown : joints 

 7, the two basal short, third and fourth longer, subequal, 

 fifth and sixth elongate, the seventh not half the length of the 

 penultimate : coxae of the four hinder pairs of legs grooved 

 on the inner aspect, and crossed with raised lines : ventral 

 plates quadrangular, narrowest behind, the margin straight, 

 smooth, yellowish brown, almost naked, the last rounded and 

 more pilose than the others. The antennae are about half the 

 length of the body, but in the male sometimes only one third 

 its length, and in the female they often considerably exceed 

 the half. There are a pair of tooth-like claws, and two 

 spines on each side beneath the caudal segment of the male, 

 but neither the claws nor spines are observable on the 

 female, the segment being merely margined with a few hairs. 

 The animal is subject to great variety in size, and also in the 

 intensity of its colour. The young are milk-white.
