the upper surface, all the earlier stages on the lower. The 

 upper surface of the moth would of course represent the 

 former and its under surface the latter. It is to be hoped 

 that the fungi attacking dead leaves in tropical America 

 will be observed from the points of view here suggested, as 

 well as the precise attitude of rest assumed by the moth. 

 ^fauHlCo It is interesting to compare with Brmmda ^^nsincc the 



small South American Locustid, Plagioiotcra hicorclata, of 

 which the upper surface is shown in Fig. 2, the lower 

 in Fig. 2a of Plate XXXIT. Instead of the complex 

 networks of small areas seen on the wings of the moth, 

 the Locustid exhibits on each fore-wing a single coarse 

 network including four large meshes and an isolated area 

 enclosing a brown curved line. The transparent portions 

 are surrounded by a brown margin, sharply demarcating 

 them from the green ground-colour of the tegraina. It is 

 probable that the Locustid in the attitude of prolonged 

 rest, with its tegmina enclosing both body and under- 

 wings, resembles a much bent or even rolled green leaf 

 which has been attacked by a species of fungus producing 

 in living leaves effects in some respects similar to those 

 wrought in the dead leaves to which the moth Draeenta 

 bears a likeness. 



The two insects come from the same Region, and both 

 are probably widespread. The Locustid is indeed known 

 to be so, while the capture of the moth in Trinidad and 

 Guatemala suggests the likelihood of an extended range.
