ONISCUS longicornis. 
Class 5. Insecta. Order 7 . Aptera.

Antennce setaceous, from 2 to 4. Body oval, 
consisting of about 14 transverse segments.

By Mr. T. W. Simmons’s indefatigable industry, in 
laudably searching into the knowledge of the natural pro- 
ductions of Great Britain, whenever he had an opportunity, 
we are enabled to figure this species. He observed this 
strange-looking animal entangled in the nets oli Dy sart, 
near Inch-Keith. 
It has an appearance that may often cause one to mistake 
the head for the tail : see the upper figure. In the middle 
figure it seems like a tumbler, or master of attitudes ; in the 
lower figure it appears to be at rest. 
The eggs are red, and adhere to the under side of the 
largest segment of the body.
