178 RHOPALOCERA. 
abundant, but still associated with S. dacinia, and connected with it as shown by 
figg. 12, 18. The same state of things prevails in Panama. In South America 
S. saundersi is far the commonest form, but still the steps to S. adelina are not 
altogether absent. 
In the Southern States of North America a form occurs which is very like S. saunders¢ 
and is prevalent in Texas. Thisis S. adjutrix, Scudder } ; but we doubt the possibility 
of maintaining its distinction. In Arizona another form occurs, S. crocale, Edw., which 
we take to be undistinguishable from S. adelina, and therefore connected with the whole 
series. 
Regarding the other names which have been proposed for varieties of this butterfly, 
S. tellias* is equivalent to S. lacinia®. WS. quehtala ® is like S. adelina above, with traces 
of the yellow band of the secondaries beneath still extant. A form identical with or 
very similar to this is S. misera™. 8. ardema is also like S. adelina, but has two rufous 
spots near the inner margin of the primaries (see figg. 12, 13). S. paupera® is like 
S. adelina above and S. lacinia beneath. SS. mediatrix® comes between S. lacinia and 
S. saundersi. 8S. pretona™ is like S. adelina, but with rufous instead of white marks 
on the primaries. 
The proposers of these names give in detail their characters; but the position of each 
is generally indicated above. 
In Guatemala §. lacinia is very abundant up to an elevation of about 5000 feet. 
Our series of varieties mostly come from the valley of the Polochic river. 
Our figures represent the following specimens :—
