itself is one of the most iiitcrestiiif^ little things imaginable, and to 

 have watched it fluttering about in the warm sunlit glades that it 

 loves is to have seen one of the most delicate and charming pictures 

 of insect life : the interest being enhanced when one knows where it 

 has come from, and how it has spent its earlier life. 

 The detailed descriptions follow : — 



Larva slender, with reddish head, prothoras and legs, the rest of the body 

 whitish. 



Head elongate, oval, sparingly behaircd ; clypeus short and broad ; under-piece 

 large, snbquadrangular, angles rounded, slightly narrower in its posterior part. 

 Antennae very higlily developed, long, fusiform, ])laced on a rounded base, obliquely 

 truncate at apex, which bears a single spinous hair. Labruni transverse, sides 

 rounded, anterior margin rounded and excised ; disc with six or so strong hairs. 

 Mandibles rather short ; right deeply toothed, left less conspicuously so. Maxillae 

 elongate, with .3-jointed palpi ; labium sub-conical. 



Prothoras, seen from above, little broader than the head ; pronotal plate pilose, 

 broadly transverse, nearly straight in front, sides sliglitly rounded, posterior margin 

 shallowly excised. Mesothorax broader, the notal plate indistinct, because con- 

 coloi'ous with the metanotum, which is membranous. The legs, which are pilose, 

 are comparatively strong, and tliere is not such great disparity between the length 

 of the pairs as in some other genera, the distal joints, especially of the fore legs, 

 spined internally. 



Abdomen : first segment broadest of all, gradually tapering thereafter ; the 

 first segment bears the usual protuberances, dorsal and lateral, the latter in the 

 shape of a rounded space covered with points and posteriorly running into a long 

 black chitinous band. Tracheal branchiae apparently ill-developed, filamentose, 

 single. Fringe also ill-developed, composed of minute hairs, modified on 8th seg- 

 ment to a row of strong points. Free part of anal limbs short, provided with 

 double hooks ; about the anal region ai-e several series of regular spines or spinous 

 hairs. 



Nymph : very long and slender, cylindrical. Antennae very long, wound round 

 the posterior end of the abdomen. Labrum shield-shaped ; mandibles slender, 

 falcate, deeply dentate. Apparently only 2nd pair of legs fringed, fringe very 

 slightly developed. Wing-eases long, narrow and acute, reaching beyond 6th 

 abdominal segment. 



Dorsal armature of abdomen : 1st segment with a rounded wart (on each side) 

 covered with points, which also occur along the posterior margin of the segment ; 

 3rd to 7th segments each with two anterior elliptical plates with backward directed 

 teeth, three or four teeth on segments 3rd and dth, three teeth in segment 5th, two 

 or three teeth in segment 6th, and two teeth in segment 7th. The posterior plates 

 in segment 5th are large, transverse, contiguous, each with twelve or so forward 

 directed teeth arranged in double series. 



Lateral fringe of very fine short hairs, commencing on 3rd segment and run- 

 ning to 8th, joining beneath. The terminal appendages reach a maximum develop- 

 ment in this species ; they are very long and slender, slightly curved at the tips, 

 which bear a number of points and a few hairs.
