INVERTEBRATE ANIMALS. 93 



Java, the species of which in outline and colouring 

 closely resemble butterflies. For an account of Mimicry 

 in Insects see the Tablet. The group is illustrated by 

 18 British species. 



Group 208.— PSEUDO-BOMBYCES. The Swifts, Lappets, 

 and Prominents include some of the most rare and 

 beautiful British Moths. Of these about 40 species are 

 exhibited. 



Upper Compartment. 

 Specimens of a Fungus, Torrubia RohertsU, on the 

 larvfe of Hepialns from New Zealand; also of 

 Torruhia milltaris on pupae of moths, collected 

 at Rainhill and presented by H. H. H. Pre- 

 pared larvfB of moths. 



Group 209.— Family URANIID^ and allies. Species of 

 Urania are frequently seen near the rivers of Brazil 

 flying in a certain direction, and following one another 

 in rapid succession for several days together; yet not 

 one is seen to return. These insects resemble butter- 

 flies, but are distinguished by the antennae, which are 

 not clubbed, and by the chrysalis, which is not angular. 

 Observe especially the very rare and beautiful Urania 

 Riphceus, a native of Madagascar, and the scarcely less 

 beautiful Nyctalemon. 



In this group also are included the Burnets, Clear- 

 wings, &c., ZygcBnidce and other Families: amongst 

 them may be noted Glaucopis caudata, with an append- 

 age resembling an ovipositor ; it is probably a mimic of 

 an associated Hymenopterous insect. 



Group 210.— Family SPHINGIDiE. <T(p\y^, the Sphinx. 

 The name alludes to the larva, which frequently carries 

 its head erect. Note the artistic correspondence between
