Color comparison of males based on two of each species collected by 

 I. L. Graf at Ohio Pyle Pcnna., Sept. 23, 1906. 



B. vinosa. 

 green obscured 



with 



Face 

 brownish. 



Dorsal thoracic stripes narrow, 

 each divided for a short distance. 



Mesepimeron and metepimeron 

 each with an inferior rounded 

 yellow spot. 



Mesepimeron and metepister- 

 num each with a small bluish 

 spot at base of wings. 



Metepimeron uniform brown 

 with exception of yellow spot 

 mentioned above. 



Wing bases above and between 

 the wings with few inconspicuous 

 blue spots. 



Abdominal segment 2 from 

 above with small median basal 

 spot, and a transverse apical spot 

 which is interrupted at the me- 

 dian line. 



Segments 3-5 each with a very 

 small apical spot on either side 

 of the median line. 



Segments 3-8 each with a very 

 small obscure pale spot at the 

 transverse carina, each spot di- 

 vided by the dorsal median longi- 

 tudinal carina. 



Apical half of 8 and all of 9 

 and 10 obscure brownish yellow, 

 each with a dorsal median brown 

 area; 10 decidedly more yellow 

 than 8 and 9. 



Seen from the side segments 

 4-8 each with a very small ob- 

 scure yellowish spot below, the 

 transverse carina dividing each 

 spot more or less completely into 

 two spots. 



Superior appendages dark 

 brown, inferior yellow, extreme 

 apex dark. 



Width of head, 9 mm. 



Clear 



B. grafiana. 

 green. 



Wider, continuous but nar- 

 rowed where the separation occurs 

 in vinosa. 



Each with a rounded blue spot, 

 the spot on the metepimeron 

 showing traces of yellow. 



Spots larger and more distinct- 

 ly blue. 



With a large distinct blue spot 

 at wing base. 



With distinct and more numer- 

 ous clear blue spots. 



Similar and also with a spot at 

 the median transverse carina 

 similar to the apical spot. 



Spots clearer and more sharply 

 contrasted with the surrounding 

 color. 



Spots cleaj blue, sharply de- 

 fined. 



8 brownish with a wide black 

 median longitudinal stripe back 

 of the transverse carina ; 9 

 and 10 pale greenish blue, but lit- 

 tle if any obscured and with black 

 markings more distinct and defi- 

 nite than the brown markings in 

 vinosa. 



Spots large, clear blue, the color

 to the dorsal spots. 



Both superiors and inferior dark
