Scotland); Europe, Asia Minor to N. Persia; 6. Larva whitish, 

 yellow, or greenish, sides brownish or pink ; dorsal line usually 

 brown or pink ; subdorsal series of spots sometimes pink ; head 

 black : on Rumex acetosa ; 7-5. The imago bears a remarkable 

 resemblance on the wing to a species of Chrysopa (a genus of 

 Neuroptcra) occurring in the same localities ; probably an 

 instance of protective mimicry, as the Chrysopa is uneatable. 



3. P. globulariae, lib. $ 26-30 mm., $ 18-20 mm. Antennae 

 not thickened towards apex, pointed. Head and thorax golden- 

 green or blue-green. Abdomen coppery or golden-green. Fore- 

 wings golden-green; termen rounded; cilia grey. Hindwings 

 grey, in $ rather darker. 



Kent to Gloucester, local ; C. and S. Europe, Asia Minor ; 6. 

 Larva green ; a dorsal row of black spots ; subdorsal line white ; 

 head and plate of 2 black : on Centaurea nigra ; 7-5. 



4, HETEROGENEIDAE. 



Ocelli present. Tongue rudimentary or absent. Antennae 

 is or more, in $ ciliated or simple. Labial palpi moderate, 

 shortly rough -scaled beneath, terminal joint very short, some- 

 what pointed. Tibiae rough-haired. Forcwings : 8 and 9 

 stalked, 8 to apex. Hindwings: 8 connected or anastomosing 

 with upper margin of cell. 



Though nowhere very conspicuous, this family attains a fair 

 degree of development within the tropics, but is elsewhere scarce. 

 Imago with forewings rather short-triangular ; the species fly 

 by night, and are retired in habit. 



Ovum oval, smooth. Larva short, stout, attenuated towards 

 extremities, without prologs; feeding exposed on surface of 

 leaves. Pupa with maxillary palpi well marked ; in a firm 

 short oval cocoon above ground. Some exotic larvae of this 

 family have groups of protrusible stinging tentacles.
