EUOLIDIA GLYPHIOA. 133 



inch and a quarter in length I described them as 

 follows : 



Long and slender for the size of the moth ; body 

 evenly rounded above, flattened below, tapering a little 

 at the extremities ; the head has the lobes rounded, 

 and is a little wider than the second segment; skin 

 smooth but not polished ; segmental divisions well 

 defined ; the anal prolegs extend beyond the fold, 

 and form a distinct angle. By this time they have 

 lost the true looper style of walking, but are still 

 half-loopers, having no prolegs on the seventh, eighth, 

 eleventh, and twelfth segments. The ground-colour 

 varies from pale salmon to dull pink, some specimens 

 having a strong yellowish tinge ; a distinct double 

 yellow line, enclosing another very fine still paler line, 

 forms the dorsal stripe ; the anterior point of the pale 

 line on the crown of the head forms the apex of a 

 triangular mark, the base of which is over the man- 

 dibles ; the rest of the head is very dark brown ; the 

 subdorsal lines are dull bluish, bordered with smoke- 

 colour, and enclose fine pale greyish lines ; below the 

 spiracular stripe is another irregular greyish line, and 

 below this, but above the spiracles, is another line of 

 pale bluish, edged with smoke-colour; the spiracular 

 stripes are yellow, rust-colour, or pink, in different 

 specimens. The colours, indeed, vary considerably in 

 different examples, in some the blue side-stripes being 

 scarcely discernible; spiracles black, as are also the 

 tubercular dots, which, though small, can be distinctly 

 seen with a lens. Yentral surface dull dark smoky- 

 purple, with two yellow central lines. 



Most of the larvae were full-grown by August 7th. 

 Length an inch and three quarters, and the salmon 

 and pink colours of the younger specimens altogether 

 lost. The ground is now of various shades of 

 ochreous-yellow, the darker specimens having a strong 

 rust tinge along the sides ; head of various shades of 

 brown, in some being of a dark sienna colour ; in all 

 there is the pale yellow front triangular mark so
