NOCTUAS.

The MOTH appears in June, and continues on 

 wing thixmghout the summer. It is com- 

 lon everywhere. (The scientific name is 

 igrotis exclamationis.) 



Obs. 1. I have followed my usual plan of 

 lescribing the caterpillar of this most destruc- 

 tive insect without comparing it with that of 

 closely-allied A gratis Segetum, and have 

 jrought out certain characters in each descrip- 

 tion not mentioned in the other ; but there is 

 great a difficulty in distinguishing the two 

 species when in the caterpillar state, that I 

 lave often found the moths of both emerge 

 )in the same turnip, when I supposed it con- 

 lined only the caterpillar of one. 



Obs. 2. The male of this species is the 

 [eart and Dart (Noctua exclamationis) of 

 [awbrth (Lep. Brit., No. 169), and the female 

 Pitchy Dart (Noctua picea, Lep. Brit., 

 To. 170). 



Obs. 3 Owing to an inadvertence, the 

 ordinary form of this abundant moth has not 

 jn figured ; the varieties represented have 

 sen kindly lent for this work by Mr. Bond 

 md Mr. C. Feiin : the spots are usually more 

 3parate and distinct.

530. THE HEART AND CLUB. The antennae 

 are decidedly ciliated in the male, simple in 

 the female : the costal margin of the fore 

 wings is straight, the tip blunt, their colour is 

 smoky gray-brown, with darker blotches and 

 numerous minute transverse lines ; the princi- 

 pal blotches are two ; the first seems to com- 

 bine and include the claviform and orbicular, 

 the second the reniform spot ; a slender but 

 double transverse line adjoins the first of these 

 on the side nearest the base, and a similar 

 double line adjoins the second blotch on the 

 side nearest the hind margin : the costal 

 margin is spotted with pale and dark ; short 

 and slender dark fines and dots are scattered 

 or sprinkled over the entire surface of the 

 wings ; in some specimens these are rather 

 crowded, in others distant from each other : 

 the hind wings are pale gray-brown with a 

 very inconspicuous crescentic discoidal spot : 

 the head and thorax are very much the same 

 colour as the fore wings ; the body the same 

 colour as the hind wings. 



M. Guenee says that he has often met with 

 the CATERPILLAR of this species, but has un- 

 fortunately neglected to describe it. I am 

 still more unfortunate in never having seen 

 the caterpillar. 



The MOTH appears on the wing at the end 

 of June and beginning of July, and often 

 swarms at the blossoms of the lime, a tree 

 that offers a banquet to bees by day, and to 

 moths by night. It seems very generally
