THE BRITISH LIPARID HIOTIIS, 143 



spines, rather scattered in comparison with the sheaf-like mass of them 

 on P. .s?H(/7/.v. 



7). fasrclina : Colour, jet black ; sm'facc, polished ; dorsal hump 

 ])rc'sent, l)ut not prononneed. Ilairs arc bright brown, and siiu])le (not 

 thonic'd), very loufi: and very thickly set on dorsal area; siija-a-, post- 

 and su])-spirac!nlar <;t()U])s can be traced, but not the trapezoidals, as the 

 dorsal hairs are too louo- and thickly set. Scars of the larval tufts 

 arc present on the first few abdominal sef^-ments. The dorsal head- 

 piece bears numerous lou<;" hairs, but I cannot trace any hairs on the 

 ventral head-])ieces. The anal horn is Ion*;' and comparatively slender, 

 much flattened on ventral side. It shows traces of longitudinal flutiug 

 or striations. The top is covered with hooked bristles or spines, which 

 are small and slender. 



On/i/ia : The dorsal hump is more marked in the ? than in the ^ pupa. 

 The wing-cases |of ? pu]ia only extend to end of 3rd abdominal seg- 

 ment, in the (^ s to end of 4th. <). antiqxia : Colour pale brown ; shell 

 very thin and transparent ; surface smooth and [)oIished. Hairs are 

 fine and weak, almost colourless, but rather numerous, ribliou-shaped 

 and twisted. Roth auterior and posterior trapezoidal, supra- and sul)- 

 spiraeular groujjs are present. There is no post-spiracular grou}), but 

 a minute tubercle is present in this ]iosition, l)caring a single suiall 

 hair ! Hairs are also present on dorsal head-piece, but not on ventral. 

 On (?) ]st, 2nd and 3rd abdominal segments there is a patch, divided 

 along median line, of whitish circular scales. These are not quite so 

 well developed as in 0. i/onostitfrna, and I have more fully described 

 them in that pupa. Anal horn is small, smooth and conical, situated 

 on the dorsal side of anal segment, rather flattened on ventral side ; 

 its armature consists of a mass of rather short and much curled bristles. 

 0, (i(»ii)sti<iiiia : Colour black, except intersegmental area, which is 

 orange ; surface smooth and shiny. Hairs are numerous, longer, and not 

 so weak as in (>. (inti<jua, their colour pale yellow, flat or ril)l)ou-sha])cd, 

 and twisted. Their arrangement is similar to those of O. anti(j7ta, but 

 not so easily traced on account of their gi-eater length and uimiber. 

 The scales which, as in O. anti(]ua, occupy the ])osition of larval tufts, 

 are discs of a more or less circular shape ; they appear to be attached 

 at the centre, and occasionally overlap one another. They have a 

 semi-transparent opalescent appearance, and are wrinkled or fluted 

 in a more or less regular spiral i)attern ; the flutes or crenulations 

 starting from a central l)utton curve outwards to the circum- 

 ference. The anal horn is smooth, cone-shaped and cylindrical, with a 

 gi'oup of much curved bristles on top, as in (). antiqua. 



Ih-maa : The i)upa of D. cinijU is figured and described in Dr. 

 Chapman's paper on the genus Anoni/cta, already referred to (ri.lr, 

 ri. ix., figs. 5 a. b. c). It lacks the hairy character of the Fiipiirid 

 pupte, but has an armature that is not unlike that of a Lij)ari(l, though 

 it diilers in that it terminates in a l>ulb, and also m the number, shape 

 and length of the terminal l)ristles.
