ANTHROCERA LONICER^. 475 



which extends over it as a complete hood of a whitish colour, trans- 

 parent and glassy-looking, with the tubercular warts united, and cover- 

 ing its whole area. The head itself is pale yellow, the labrum white, 

 the clypeus separated by a rather dark suture from the cheeks, the 

 maxilla? are red-brown, the other mouth-parts are pale brown or 

 yellowish, the antennaa prominent, pale yellow in colour, with a 

 whitish base ; the ocelli large and intensely black, forming a promi- 

 nent patch on each cheek. The fuH-t/rown larva is described by 

 Buckler as being nearly an inch in length, very plump, with the 

 segments deeply divided, the head being small and retractile, black 

 and shining ; the mouth ochreous-yellow margined with black ; the 

 palpi yellow at their bases with black tips ; the anterior legs black ; 

 the ventral prolegs of the ground colour of the body, a velvety bluish- 

 green. Longitudinally, there are subdorsal and spiracular rows of 

 black velvety blotches, and between them, at the end of each segment, 

 a transverse, pale yellow, semi-transparent, oblong mark. Laterally, 

 the subdorsal black blotches are seen to consist of a thick oval blotch, 

 followed by a thinner reniform blotch on each segment, the former 

 being placed on the anterior part of the segment. The spiracular 

 row follows a similar order, but the blotches are thinner, and more of 

 a curved wedge form, with a tendency to unite below. Above the 

 legs is a fine longitudinal interrupted black line. The warts are green, 

 and bear fascicles of short whitish hairs. A second form of the larva is 

 described by Buckler as having the green ground colour a little paler 

 and yellower than the previous form. The subdorsal black blotches 

 consist, on each segment, of a thick, irregular, oblong blotch, placed 

 anteriorly, followed by another, similar in shape, but rather thinner 

 below. The spiracular row is rather shorter, but similar, more pointed, 

 however, at the top, and meeting below by means of a curve from the 

 anterior blotch, the hinder blotch having a little tail at the bottom. 

 Above the feet is an interrupted black line. The true legs are black, 

 the ventral prolegs broadly ringed with black above, their extremities 

 tipped with black. Briggs emphasises (Trans. Ent. Soc. Lond., 1871, 

 pp. 438-439) the following characters in the larva of this species : 

 (1). Body with lony white hairs scattered over it, with some black 

 hairs mixed with the white on the back ; hairs much longer and more 

 dense than in the other species of Anthrocerids. (2). Below the black 

 dorsal spots a narrow pale longitudinal line, with a very conspicuous 

 bright yellow transverse spot in the fold, formed by the hind margin of 

 each segment. Below this line is another (spiracular) row of black 

 spots on each side, two on each segment, united at their lower 

 extremities, the posterior spot emitting a small transverse spot towards 

 the prolegs = the " little tail " of Buckler. (3). The subspiracular 

 is a narrow lateral line. Boisduval diagnoses the larva as follows : 

 " La taille de celle de l&filipendulae. Elle estd'un vert pomme, et elle 

 a, sur chaque cote du corps, deux bandes noires formees de taches 

 interrompues par les incisions : ces bandes s'etendent de la tete a 

 1'anus, et 1'inferieure est plus e"troite. On remarque sur chaque 

 anneau un point jaune plac entre les deux bandes ; le corps est 

 pubescent, comme dans toutes ses congeneres " (Mon. des Zygen., p. 58). 

 COCOON. Attached to a grass culm, flower stalk, or twig of a tree. 

 It is fusiform in shape, with a narrow base, the silk not always extending 

 round the twig to which it is attached. The cocoons vary much in
