MACROTES NETRIX. 

 (Plate CXLV., Fig. 3.) 



Geometra netrix, Cramer, Pap. Exot. ii. pi. 151, Fig. E (1777). 

 Phal&na netrix^ Sepp, Surin. Vlind. i. p. 69, pi. 31 (1848).

This curious Moth, which expands two and a quarter inches in 

 expanse, is bright green when alive, but soon fades to dull green 

 or olive. The costa and hind margin are narrowly reddish, and 

 there is a sub-marginal row of reddish dots. In the middle of 

 the hind-wings is a large transparent spot, bordered with black 

 and red. 



The larva is very long and slender ; the head and legs are 

 black, and there are two white dots at the back of the head, 

 which is edged behind with orange ; the pro-legs are orange ; 

 the back is dotted with white, and there is a slender inter- 

 rupted stigmatic line. It feeds on a species of Ficus (?). The 

 larva rests in the usual position assumed by the larvae of 

 Geometra, and drops down by a silken thread, when touched. 

 The pupa is green, very long and slender, and is said to rest 

 on the surface of the ground without a cocoon. 



This insect is found in a great part of South America, and 

 in the West Indies. 



GENUS MECOCERAS. 



Mecoceras, Guenee, Spec. Gen. Lepid. Uran. et Phal. i. p. 388 

 (1857); Walker, List Lepid. Ins. Brit. Mus. xxii.p. 606 (1861). 



This genus differs from the last in the wings being rounded, 

 and the hind-wings dentated, and in the antennae of the male 

 being less broadly pectinated, and simple at the extremity.
