well as two dorsal cerci or processes. The hairs or hair-tufts on tubercles 
arranged as in Lepidoptera are not found in this order, and larvae, if 
hairy, have long tufts not arranged in series. No larval form can be con¬ 
fused with the Coleopterous larvae which live free lives, the characters of 
Neuropterous, Hymenopterous, Lepidopterous ^ Dipterous larvae be¬ 
ing wholly different.

There are a few prominent points about Coleopterous larvae that we 
may notice here. The tarsi are two-clawed in the Adephaga only (except¬ 
ing Haliplidce from these). Anal cerci occur only in Haliplidce , Hydrophil- 
idce , Silphidce, Scaphidiidce, Staphylinidce, Histeridce and Elateridce in 
part, as well as in the Adephaga. If we except the above, the larvae of 
all have legs except Bruchidce, part of Cerambycidce and Buprestidce . 
Omitting all the above, the Scarabaeoid (white, curved, wrinkled) grub 
occurs only in Scarabceidce , Melolonthidce, Lucanidce, Passalidce 9 Ptinidce, 
Bostrichidce and part of Chrysomelidce (e.g. Clythrince). In the Dermes- 
tidce, the body is clothed in long fine barbed setae, usually aggregated
