52 HADENA DENTINA. 



lobe and coarsely reticulated with blackish ; anterior 

 legs pinkish, the others pinkish-grey, rather shining, 

 as also is the head, but for the rest there is no gloss, it 

 having a dull blackish and almost rough appearance. 

 The larva now fed slowly and liked garden lettuce 

 when given to it, but fearing to scour it too much I 

 continued to give it plantain, knotgrass, etc., but it 

 ate very little indeed, and I saw on the 17th it had a 

 conglomeration at its tail. It had grown much 

 blacker lately, and seemed inclined to hibernate. On 

 the 20th it died, and then when too late I regretted 

 not having given it lettuce entirely. (W. B., August, 

 1876 ; N.B., III, 107 and 131.)

Plate XCIV, fig. 2. 



I have been much indebted to the assiduity of Mr. 

 Batty, of Sheffield, who kindly sent me, in July last, 

 some larvae of this species in different stages of growth, 

 reared from eggs on broad-leaved plantain ; they, 

 however, seemed afterwards equally partial to Poly- 

 gonum aviculare, and fed up rapidly, retaining their 

 colours and markings throughout their growth. They 

 were full-fed and had gone to earth by the 28th of July, 

 and on the 23rd of August one moth emerged, greatly 

 to my surprise, and is a dark smoky-brown specimen. 



The larvse are uniformly cylindrical until nearly 

 full-grown, and then become a little tapering towards 

 the head ; ground-colour green or yellowish- green, 

 most minutely irrorated more or less with yellowish 

 atoms ; the dorsal line rather indistinct, and slightly 

 darker than the ground-colour ; the subdorsal line 

 absent in some, but present in others as a fine black, 

 rather oblique streak on each segment, terminating at 

 the hindermost tubercular dot; the dots are black, 

 and arranged on the back in the usual trapezoid form ; 

 the spiracular line is composed of a black fusiform
