wings crimson, below with lilacine streak"; forest, June 4, 1 $ . 

 Volcan Santa Maria, 5000 feet, April 19, $ 9 "in cop." 



The lengths of the abdomens and hind wings of the three males 

 and one female, respectively, are: 41.5, 29.5; 36.5, 27; 43, 35; 36, 34 

 mm. All four specimens have pterostigmata. 



Cora marina Selys (race alcyone Selys?). Cayuga, near stream 

 in bananas, May 28, 1 $, "Black with subdorsal dark grey inter- 

 rupted streak. Ventrally dark grey." Abd. 28, hind wing 26 mm. 

 Front wings: from base to nodus 13.5, from nodus to apex 14 mm.; 

 29 antenodals, the llth thicker, 24 (right), 22 (left) postnodals; 

 extreme length of the stigma 3.22, its costal edge 2.38 mm. The 

 nasus is crossed by a median black band .35 mm. in width. The 

 mid-dorsal black band on abdominal segments 2-7 is wider on each 

 segment than on that preceding and on all of them wider than 

 the lateral pale band; in side view of the abdomen the half of this 

 mid-dorsal black band that is visible is from one-sixth (on 2) and 

 one-fourth (on 3), to one and one-half times (on 7), as wide as 

 the pale lateral band. The black mid-dorsal thoracic stripe is at 

 its narrowest place .59 mm. in width, and the black stripes on the 

 humeral and first lateral sutures reach widths of .35 and .21 mm. 

 respectively. 



This female is similar to Costa Rican females which I have 

 referred* to marina or to forms intermediate between marina 

 and alcyone, but is still smaller and with more black on all three 

 regions of the body. Dr. Ris, writing of specimens of marina 

 from Panama and Bugabita in Panama, says : 



"Die Serie entspricht somit den kleinen Massen [der C. marina] 

 bei Calvert, und bei Selys den Massen der C. alcyone (3. Addit. 

 Synops. Calopt., p. 39, 1873, $ Bogota). Diese ist so gut wie sicher 

 keine besondere Art, sondern mit diesen kleinen Exemplaren der C. 

 marina identisch." (Archiv f. Naturges., 1916, A, 9, p. 19, 1918.)
