Description of the Larva ofTimatidra amataria. — Rests 

 in a somewhat bent position; the back slightly arched; the 

 three anterior segments bent at an obtuse angle with the 

 arched back, and directed upwards ; the head prone and 

 closely tucked in, the mouth coming in contact with the first 

 pair of legs : when touched or otherwise annoyed, it falls 

 from its food-plant, bent nearly double, and remains perfectly 

 motionless, as though dead, for many minutes : the head is 

 small, but of nearly equal width with the 2nd segment ; the 

 2nd and 3rd segments are small, flattish, and somewhat 

 quadrate ; the 5th segment is much swollen and laterally 

 dilated, and as the larva stands semi-erect, attached by its 

 claspers only, its appearance with this dilated neck, if we 

 may so call it, reminds one of the figure of the cobra when 

 irritated ; all the remaining segments are slightly swollen at 

 the sides, and restricted at the incisures ; the skin is slightly 

 folded transversely, but this folding is neither so marked nor 

 so regular as is generally the case in the larvae of the genus 

 Acidalia ; it is most observable on the 2nd and 3rd segments 

 and on the posterior half of the other segments : there are no 

 anal points, but the anal claspers are rather large and de- 

 cidedly spreading. The colour of both head and body is 

 umber-brown variegated with lighter brown ; the head is 

 pale and reticulated down the middle of the face, but on 

 each cheek is a still paler as well as a darker mark : these 

 markings on the head are continuous with the dorsal orna- 

 mentation of the body, which consists, ^'rs/, of a pale medio- 

 dorsal and rather narrow stripe, intersected throughout by a 

 darker line ; and, secondly, of four very conspicuous lozenges, 

 seated respectively on the 6th, 7th, 8th and 9th segments ; 

 each of these is pointed at its anterior, but abruptly truncate 

 at its posterior, extremity ; the medio-dorsal stripe passes 

 through all these ; each of these segments has a pale, almost 

 white, lateral mark below the lozenge, and these lateral
