Lana. — In ^hajw «if the nsunl oniscifonn (wood louse) type but the se*,'- 

 ments o-lO are dorsally very tumidly prominent as for that, also laterally 

 along the dorsoventral margin they are well separated ; segment L* is more or 

 less semicircular in shape, hiding the head in repose completely, but it is very 

 nuich thickened, the dorsal portion being difierentiated from a dorsoventral, 

 tumid tlange by a deeply impressed spiracular line (that is in the spiracular 

 region) this dorsal part trapeze-shaped, somewhat depressed in the dorsal 

 line with a diamond-shaped, tlat-bottomed, rather snuiil depression on the 

 posterior, dorsal region up against the posterior margin ; segment 3 is sud- 

 denly broader and higher than segment '2, and longitudinally very convex ; 

 segment 4 rather similar in shape except that the fall to the front margin 

 is not so iierpendicular as in 3 and it is also not so long as 3 ; segment h 

 exactly like 4 and is the highest part of the larva, after which the dorsal 

 line graduall}-^ slopes away to the anal v\\(\, segments 6-10 being like o ; 

 segment 11 much lower and flatter dorsally than 10, the gland situated, 

 mouth-shaped and transverse, on its hinder declivity ; segment \'2 also 

 only very slightly convex longitudinally, nearly Hat dor.sal]y transversally, 

 its hinder margin strongly curved forwards, the small round-mouthed, 

 short, white, cylindrical, sparseh' spine-topped protrusible organs in the 

 usual position, the segment being perhaps slightly tumid where they are ; 

 segment 13 again lower than the hinder margin of 1:?, nearly quite flat, 

 sloping at about 30*^ to the longitudinal axis of the larva and hardly difie- 

 rentiated at all from segment 14, these two together — if indeed segment 

 13 is the portion anterior to the end which is indicated by a transverse, 

 rather indistinct furrow — forming the anal end of the larva which is 

 shortly parabolic, slightly tumid and inclined to truncation ; the lateral 

 outline increases suddenly in breadth at segment 3 and very gradual to 

 middle of body after which it gently decreases again to segment 12, then 

 slightly more rapidly- to the extremity ; transversely the section of the body 

 is a short parabola and the body is very prominently, tumidly flanged sub- 

 spiracularly though the flange is not sudden or very pronounced in apjaear- 

 ance: its ventral surface (of this flange) being in a horizontal plane, the bod}- 

 being suddenly narrowed below it so as to form a sort of pedestal for the 

 dorsal visible pai-t which is a usual formation in all lycienid caterpillars. 

 Head shining, round small, light yellow with the labrum white, the broad, 

 transverse, shallowly and widely emarginate ligula reddish-brown, the basal 

 antennal joint white, the second reddish, the mandibles light, tipped brown, 

 the eye curve filled in with black ; the clypeus is large, triangular, more 

 than half the height of the face, outlined slightly dusk}'. The surface of 

 the body is extremely minutely shagreened-shining and covered all over 

 densely with very minute, shining tubercular prominences w hich are gene- 

 rally higher than broad and are separated from each other by about their 

 own height, sometimes by more ; these prominences are irregularly and 

 very minutely spiued ; there are also some little regular , star-like bodies, 

 some very low and sessile so to speak, others very shortly stemmed — 

 though the stems are not in the nature of stalks at all but are the same 

 thickness all along — and they are either brown or green or nearly white; 

 each one of these prominences has a little glass-like, shortly stemmed disc 

 proceeding from the top and directed out at right angles to it — otherwise, 

 parallel to the body-surface : in some cases this disc is hardly developed 

 at all, formirg what looks like a thick, glassy hair, sometimes it is quite 

 undeveloped ; There are a few very short, porrect, fine, whitish hairs on 

 the dorsoventral margins of segments 2 and 14 and a few on the leg-bases
