LEPIDOPTERA. 



Thorax considerably elevated. The pupa of the green variety 

 is suffused all over with green. 



Eupithecia suhnotata. Ground-colour dull yellowish- 

 green, pale green or reddish-grey, with a chain of dull olive 

 lozenge-shaped dorsal spots, becoming confluent towards the 

 head and tail, and often bordered by an indistinct olive 

 line. The spots and lines sometimes very faint. Segmental 

 divisions yellowish or reddish. Spiracular line yellowish. 

 The whole body very rough, thickl}^ studded with minute 

 white tubercles and black spots, and sprinkled here and 

 there with short stumpy hairs. Belly pale green, with an 

 interrupted line running the whole length. Feeds on the 

 seeds and flowers of various species o^ Atriplsx and Cheno- 

 podium, in August and September. It seems to prefer the 

 banks of tidal rivers; I have taken it in profusion on the 

 banks of the Orwell and the Stour, near Ipswich, but have 

 also met with it in some plenty in waste gi-ound near Bexley ; 

 it is not so easy to rear as others of the family, and often 

 pines in confinement. The pupa, which is enclosed in an 

 earthen cocoon, has the wing-cases dark green. Thorax and 

 abdomen yellowish, the latter not so tapering as many of the 

 other Eujnthecice. The perfect insect appears in June and 

 July. 



Eupithecia vuhjata. Common as this insect is every- 

 where, the larva seems to be but little known ; 1 have never 

 myself beaten it, but have several times reared it from the 

 eggs. It so closely resembles that of E. cr.stigafay that it 

 requires a very practised eye to distinguish it. It is slender 

 and tapers towards the head. Its general colour is reddish- 

 browai or dusky olive, along the centre of the back a chain of 

 dirty greenish, lozenge-shaped spots, becoming confluent at 

 the capital and anal segments. Spiracular line waved, yel- 

 lowish, occasionally interrupted with black. Segmental
