1. Atom (Atomus). A very minute dot. 
2. IrroraTeE (Jrrorata). Sprinkled with atoms, as the

3. Gutta (Gutta*). A roundish dot, intermediate in 
size between an atom and a macula. 
4. GuttTaTE (Guttata). Sprinkled with gutte. Ex. 
Coccinella L. 
5. Macuta (Macula). A larger indeterminately shaped 
spot. 
6. Macuuate (Maculata). Painted with such spots. 
Ex. Phalena grossulariata. 
7. Lirura (Zitura). An indeterminate spot growing 
paler at one end, as if daubed or blotted. 
8. Lirurate (Ziturata). A surface painted with one

@ Linné in Coccinella has employed the term Gutta for a white or 
yellow spot in a darker ground, and Pustula fora red spot in a black 
ground. We thought one term sufficient to express spots bigger 
than atoms.
