Felder, and also Haase, regarded this species as a near ally of P. 

 machaonides. However, it is closely related to P. garamas (= asclcp/m), near 

 which it was placed by Oberthlir. The shape of the hindwing is practically the 

 same in P. Iiomeriis, garamas, wrirscewiczi , and judicaiil. The serration of the 

 costal margin of the forewing is not quite so strong in P. komerus and garamas as 

 in the other species. The agreement in pattern between P. homerus, toarscewiczi, 

 cacicus, garamas, etc., is easily perceived in spite of the specific differences. The 

 white spot on the palpus so characteristic for P. aristeus, P. cleotas, and allies is 

 also preserved in P. homerus. The cell of the hindwing of P. komerus is short and 

 broad, being widest near the apex, as in many specimens of P. garamas syerha. 



Genitalia : S . Tenth tergite broad proximally, strongly narrowing towards 

 apex ; sternite on each side with short projections, the anterior one being somewhat 

 acuminate, anally in middle a conical tooth as in P. aristeus ; harpe similar to that 

 of P. aristeus, nearly as long as the clasper, linear, flat, truncate at apex, the two 

 angles produced into a straight thornlike process, the lower one being sometimes 



very short. ?. Edge of vaginal orifice anteriorly raised into a short, broad, 



smooth, rounded tubercle, which is concave on the posterior side; on each side far 

 back a high ridge which separates further i'routad into two ridges, the inner one 

 ending in a long acute jirocess as iu P. aristeus and allies.
