244 THE CANADIAN ENTOMOLOGIST. 



illustrations, especially of the acts of oviposition, copulation and emer- 

 gence of the adult. 



The North American rpecies of yEshna appear to resolve themselves 

 into six groups, and about two-thirds of the monograph is devoted to very 

 full and orderly descriptions of the twenty species and geographical sub- 

 species found in North America. As an example of monographic treat- 

 ment, this volume would be difficult to surpass, both in its broad and 

 thorough character and in the unusual excellence of the author's numerous 

 illustrations. 



In congratulating the Editor of our journal on the production of so 

 useful and excellent a monograph, which will bring great credit to Cana- 

 dian entomology, we should also like to express our great indebtedness 

 to the author's father. Sir Edmund Walker, for his generosity in rendering 

 possible the illustration of the monograph by so excellent and large a 

 series of plates, and which has enabled justice to be done to the excep- 

 tionally well-drawn figures. C. Gordon Hewitt. 



A NEW PAPILIO FROM CENTRAL AMERICA. 



BY GEORGE A. EHRMANN, PITTSBURG, PA. 



Papilio chromealus, sp. n. 



Closely allied to P. copanœ Reakert. Upper side of all the wings 

 with a golden sheen (bluish-green in P. copanœ) \ submarginal arrow 

 shaped spots of the fore-wings orange instead of yellow. On the upper 

 side of the hind wings the submarginal row of spots is identical with that 

 of P. copanœ except in colour, the costal spot between nervules i and 2 

 being pale buff, the other four spots between nervules 2 and 5b deep orange 

 chrome. The spot between nervules 5b and 5c is pure white. The spot 

 between nervules 5c and 6 is the last spot and is also deep orange chrome. 



The colour and all the markings of the underside are the same as in 

 P. copanœ.. 



Habitat. — Honduras, Central America. 



This fine Papilio was collected near the base of the Congrehoy Peak 

 in the Province of Yoro by the late Dr. Carl Thime and sent to me with 

 several thousand other Lepidoptera from various localities in Honduras. 



P. cJu-omealus is a very conspicuous Papilio and if not a distinct 

 species it is assuredly a beautiful variation of P. copance Reakert, from 

 Guatemala.
