36 EXHIBITS. 
He also exhibited examples in all stages of a species of 
Epilachna, a voracious beetle usually found feeding on 
Solanum nigrum, but also affecting the tomato, the potato, 
and other plants of the same natural order. In reference 
to this exhibit it was pointed out that it was the character 
of the Coccinellidz, of which Epzlachna was a member, to 
occur at times in immense swarms, and that in the event 
of such an occurrence potato-growers in Queensland would 
be great losers. 
Two other insects were also exhibited by him as being 
natural enemies to larve of the Epzlachna, viz.:—a small 
ichneumon, to whose fatal attacks they were especially 
subject, and a moth (Fam. A/uctidz), whose caterpillar 
appeared to devour the chrysalis cases. 
Mr. G. Watkins remarked that this beetle had already 
done great damage to potato-growers in the Moreton 
District. 
Mr. H. Tryon also exhibited a worn valve of the shell of 
a Trigonia, found recently at Camboyuro, Moreton Bay, 
representing a species which he stated to be apparently 
different from those hitherto described.
