Novius ( Vedalia) cardinalis Muls. 
(Principal enemy of the fluted scale [Icerya purchasi]. ) 
Enlarged model of the adult of this insect, the introduction of which from Australia 
has effected what was impossible by any other means—the practical annihilation of 
the fluted scale in California. 
Enlarged models showing structure and characteristic appearance of the larva and 
and pupa. 
THE ‘‘ KISSING BUG.” 
Reduvius personatus Linn. 
Enlarged model of one of the group of true bugs, generally known as ‘‘ assassin 
bugs,’’ which of late years have acquired a certain newspaper notoriety through their 
supposed preference for the human lips. 
They feed on other insects, which they pierce with their strong beaks; some species 
are frequently found in houses, attracted by light, and they may, if they believe them- 
selves in danger, accidentally or in defense, pierce the human skin with their beaks, 
causing a painful wound, and often blood poisoning through the introduction of the 
germs of putrefaction. 
ORANGE RUST-MITE. 
Eriophyes (Phytoptus) oleivorus Ashm. 
Wax models of oranges. showing work of the orange rust-mite.

Plasmodium malarie. 
Twenty-nine enlarged models, illustrating the life history of this parasite in the 
blood of man and in the mosquito (Anopheles). 
The models exhibited show: Development of spores in the blood of man; develop- 
ment of ‘‘ crescent’? in the blood of man; development of ‘‘ gamete” in stomach of 
mosquito; development and fertilization of ‘‘ zygote’’ in stomach of mosquito; devel- 
opment of ‘‘zygote’”’ in stomach wall of mosquito; ‘‘ zygote’’ filled with ‘‘ blasts’? 
and ready to burst; free endospores, free blasts, and spermatozoa.
