antennae, the others opposite the members of the several pairs of 

 legs, the first few however smaller and not so well-defined as the 

 others. As regards details the specimens may be distinguished as 

 follows : — (a) the median line dark ferruginous red, the papillae 

 for a little space on each side of it a lighter and less intense red, 

 most noticeable at the knot-like enlargements where there is a 

 distinct somewhat triangular patch on each side extending out- 

 wards a little way and tapering slightly ; on the sides of the 

 body extending some little way dorsad of the attachment of the 

 legs is a broad lateral light red or ferruginous stripe, separated 

 from the median nodose line by an intervening broad band on 

 each side in which to the unassisted eye a dark tint — dark brown 

 or black— is predominant, though there is a good deal of incon- 

 spicuous red, examination under a low objective showing that some 

 of the papillae ai'e red, or have red bases and black apices, on a dark 

 back ground ; the lateral red stripes pass into the still paler red 

 of the undersurface which just ventrad of the bases of the legs 

 shows small irregular blackish patches, the inner su.rface of the 

 legs also streaked longitudinally with black, and a few small 

 black patches at intervals in the median line ; the head beneath 

 all round the oral aperture, the colour extending upwards to 

 between the bases of the antennae, black : (b) the median nodose 

 line black, the rest of the body to the naked eye of a fairly uniform 

 dark tint (black with a tinge of purplish\ but with a lens one 

 sees that there is a good deal of inconspicuous' dull red as there 

 are not only isolated red papillae but the transverse rows of them 

 alternate pretty regularly with rows of dai'k ones ; lateral stripes 

 are not defined, but the papillse on the flanks ai-e paler in colour, 

 some of them almost whitish ; the undersurface is paler in colour, 

 with a blackish longitudinal streak on the inner surface of each 

 leg : (c) somewhat intermediate in character ; the median nodose 

 line black, each of the enlargements in a patch of lighter colour of 

 the same shape as in (a) but of a light and rusty tint ; lateral 

 stripes are not well defined, but above and corresponding with 

 the interval between two consecutive legs on each side, there is 

 an irregular rusty almost yellowish patch bordered above and 

 below by an irregular black patch ; the rsst of the body dull rusty 

 red, almost brown, blotched with black ; the undersurface shows
