and its ally are solely from our region. P. branchus and its allies are also nearly all of 

 them peculiar, but have relations in Tropical South America. The same is the case 

 with P. phaon. 



c. General colour of the wings brownish black, secondaries with submarginal red spots. 

 c'. Margin of secondaries serrate, median nervure prolonged to form a short tail.

Boisduval described specimens of this species from Mexico, where it is now known to 

 be abundant over the southern portion of that country. It is also widely distributed 

 in Guatemala, and is found at elevations varying from 1500 to 5000 feet above the sea. 

 It has a superficial resemblance to P. photinus, especially as regards the distribution 

 of the red spots on the secondaries; but the two insects are really very distinct, 

 P. thymbrceus lacking the opalescent lustre of P. photinus ; it, moreover, ranges to a 

 higher altitude in the mountains. 



25. Papilio aconophos.

A species of rather doubtful value, the only difference between it and P. thymbrceus 

 being the presence in the latter of two series of red spots in the secondaries instead of 

 one. As this second series in P. thymbrceus is rather variable, and shows a tendency 

 in some specimens to become obsolete, P. aconophos may be only an extreme form of 

 P. thymbrceus in which the inner band of spots has disappeared. Our specimens,
