MALACODERMI. Prosternum not produced in front, not pointed 

 behind. Antennae serrated, or produced more or less at the side 

 of the joints. Body frequently soft. Larvae animal and vegetable 

 feeders ; the perfect insects mostly on flowers. 



The families of the Malacoderms are variable in their appear- 

 ance and habits ; the name itself is only applicable to the Tele- 

 phoridae. The larvae of the first four families are wood-eaters, 

 but a few feed on animal substances. Some of the Cleridae, the 

 larvae of which are mostly animal-feeders, have frequently clavate 

 antennae ; in Ehipiceridae the antennae are flabellate or pectinate, 

 with sometimes as many as forty joints. Some of the females of 

 Lampyris are larvaeform and phosphorescent ; they feed on living 

 snails. The phosphorescence, when present, is, in most cases, 

 common to both sexes. Aspisoma lineatum is the common fire- 

 fly of the Amazon district ; Luciola italica of Southern Europe.
