Dury: Coleoptera of Cincinnati. 153 
SCARABAID. © 
An extensive family of large insects. Some of the tropical 
forms are giants of the beetle tribe. MDyzastes, sometimes called 
the ‘‘Rhinoceros beetle,’’ is our largest coleopteron. Its larva is 
a huge grub of a dirty yellowish color, and feeds on decaying 
wood. One of the peculiarities of this species is the very power- 
ful and strange odor given off by the adult beetle. Ina Bulletin 
of U.S. Dept. of Agriculture; New Series No. 36, page 28, isa 
paper on the species, with most superb figures of the larva and 
pupa, naturalsize. Incollecting the coprophagous Scarabeide by 
throwing the dung, in which many species live, into a bucket of 
water they will come out and can thus be cleaned, before being 
put into the bottle.
