 absolutely indistinguishable fromjfajcar. Genitaiia fig. 3.

S. megasomoides Walk. 



Walker describes a male from Bogota expanding 45 mm. 

 Druce remarks that the type is in his collection and seems doubt 

 fully distinct from trimacula Sepp. However, I imagined that 

 it will prove an earlier name for S. extensa Schaus. Trimacula, 

 as then known to Druce, included all the Mexican forms, among 

 them extensa. I have not yet seen trimacula from Mexico. The 

 sexual organs of the type of megasomoides should be examined.

S. plora Schaus. 



Mr. Schaus describes a form close to what I identify as modesta 

 below, but apparently smaller. There is nothing in his descrip 

 tion either, to exclude extensa Schaus or megasomoides Walk. 

 I had his typical male specimen before me, but did not examine 

 the genitalia. Perhaps Mr. Schaus, owning the specimen him 

 self, will feel at liberty to do so.

S. modesta Cram. 



Kirby includes this species under Elysius, an Arctian genus. 

 But this is one of his less fortunate guesses. The figure obviously 

 represents a Sibine. It is a female, dark brown with a general 

 purplish cast, the red apical stain well marked and no white dots. 

 Expanse about 54 mm. I identify with this five specimens re 

 ceived from E. Wittkugel, San Pedro Sula, Honduras. The 

 spots are greatly reduced, nearly absent, and the whole insect has 

 a purplish cast, reminiscent of Cramer's figure. Mr. Schaus 

 loaned me a male which he had identified as modesta and which 

 may not be the same species which I here so identify. But as 

 he has not published anything definite on the subject to my knowl 

 edge. I feel free to restrict Cramer's indefinite term as seems to 

 me most probably correct. AJfinis Moschl.. described from one 

 female, is doubtless synonymous. I have a female specimen from 

 Paramba, Ecuador, which agrees entirely with Moschler's de 

 scription and I see no reason to seperate it from modesta. Geni 

 talia shown in fig. 4.
