60 BRITISH LEPIDOPTERA. 



This race was named in order to do away with the circum- 

 locution continuously involved in calling it the south of France 

 form of L. quercus. The nearness of the imagines of this form to 

 those of L. var. viburni would make it impossible to discriminate 

 the two forms, which also occur in the same district, but the 

 larval distinctions are most marked and the peculiarities are main- 

 tained when the forms are inbred in confinement. L. var. meridion- 

 alis is Guenee's Provencal quercus , and his remarks thereon are 

 fully quoted in our account of L. var. viburni (posted).

 Milliere, in litt. — Spartii-viburm '. s . D'un brun cafe ou violet brule, tresmat. 

 Moyen. Ailes un peu carrees. Ces bandes moins jaunes aux premieres ailes ; 

 celle des superieures etroite, bien coupee des deux cotes, droite, avec un sinus a 

 chaque extremite ; celle des inferieures arquee - coudee, aussi etroite qu'aux 

 superieures et nettement detachee de l'espace terminal, qui est brun avec la 

 frange fauve. Jamais de tache humerale. Antennes d'un brim rouge a sommet 

 blanc. ? . Grande, a ailes larges, ni courtes ni oblongues, mates, d'un jaune 

 ocrace rechauffe de brun violet ; a nervures plus claires ou concolores ; base et 

 disque des inferieures d'un brun violet ; bandes nullement dentees quand elles 

 sont visibles; frange des inferieures roussatre avec l'extremite seule d'une teinte 

 paillee (Guenee). Egg : Oval in outline, only slightly longer than wide ; a deep 

 and dark-coloured depression on upper surface, the microp)'le a distinct blackish 

 dot in very regular depression at one pole of egg, a minute dot at opposite pole; 

 dull-greyish or stone colour, with a slight purplish tinge and darker markings 

 (under microscope greyish-white, irregularly marbled with purplish and fuscous- 

 brown) ; the surface covered with distinct polygonal pitting ; the markings 

 decidedly opalescent ; the micropylar depression composed of a number of very 

 close cells of a deep purplish-brown hue, which form concentric rings about the 

 tiny Stella forming the central point of the depression ; this depression surrounded 

 by a faint, irregular, ochreous -fuscous patch, less defined and characteristic than 

 in the egg of callitnae; the remainder of the shell at this end is sparingly 

 sprinkled with small fuscous marblings, some distinctly ochreous ; the black points 

 at the corners of the polygonal reticulation very minute at poles, not noticeable 

 on other parts of the eggs. [The eggs examined are all very uniform in their 

 markings and coloration ; the purplish spots remind one of the coloration of the 

 marblings of a yellow-hammer's egg.] (Tutt). Larva : First instar : Head, round, 

 black, shiny, division of lobes distinct, covered with tine hairs, mouth -parts 

 yellowish, some white markings on lower part of face. Body : cylindrical, pro- 

 legs long, lifting body well off surface when crawling; prolegs placed well under 

 bod)-, but anal claspers very widely apart; prothorax wider than head, meso- 

 and metathorax narrower but much longer than prothorax, and rather 

 longer than the abdominal segments, which are almost equal ; the prothorax 

 divided into two large subsegments, the meso- and metathorax and abdominal 

 segments into six subsegments each ; scutellum large, smooth, but much special- 

 ised, divided centrally to form what resemble two huge, flat, oblong, orange- 

 coloured tubercles; tubercles on dorsal area much specialised, forming wart- 

 like cushions covered with hairs; four of them may be homologised as 

 i and ii on either side, but others are supplementary (secondary tubercles) ; 

 the pair representing i on abdominal segment 8 are raised into an ill- 

 developed hum]); the lateral tubercles less specialised, not so flat (superficially 

 more like the Liparid larval type of wart), raised, and emitting numerous hairs; 

 iii distinct, iv -| v almost postspiracular, a supplementary prespiracular on 

 abdominal segments placed very far forward ; also numerous small supplementary 

 hair-bearing tubercles; the prespiracular (ear) tubercles of prothorax very large, and 

 appear to be the least modified of any. The ground colour of larva slate or dull 



blue, legs and prolegs yellow ; a faint but dark mediodorsal line on thoracic and 

 hinder abdominal segments (strongest on 8th), very narrow ; an ill-defined whitish
