 Gypona bimaculata Woodworth, Illinois Lab. Nat. Hist., vol. 3, p. 32, 1896. 



Tlie identity of this species in the past has been much confused, 

 owing probably to its variation in size and color. It has the general 

 form and shape of meditahunda Spangberg, but is somewhat smaller 

 and has a distinct coloration. The wings are smoky and dark, 

 which show through the semitransparent inner border of the elytra, 

 making a contrast to the costal border, which is bright yellow, orange, 

 or rosaceous. There are four small black spots on the elytra which 

 are always more or less distinct. 



The species is rather common throughout the eastern half of the 

 United States. Records are at hand showing its occurrence from 

 Minnesota and Nebraska southward to the Gulf and eastward to 

 the Atlantic. 



17. GYPONA LIMBATIPENNIS Spingberg. 



Gypona limbatipennis SpAngberg, K. Svenska Vet. Akad. Handl., vol. 5, No. 

 3, p. 47, 1878. 



Tliis species belongs to the jjectoralis Sp&ngberg group, but differ- 

 ing from that species in the more reflexed anterior margin of the 

 vertex, comparatively smaller ocelli, and darker coloration of the 

 elytra. The specimens examined are comparatively narrow for their 

 length. The costal border of elytra is yellowish, the remainder 

 being dark brown to nearly black. The vertex is considerably 

 depressed behind the anterior margin giving the margin the appear- 

 ance of being reflexed. 



The only records of its occurrence are from Illinois and New York. 

 It is a rather rare species. Fitch gave the manuscript name of 

 fraxini for this species.

 Gypona mexicana SpAngberg, K. Svenska Vet. Akad. Handl., vol. 5, No. 3, 

 p. 18, 1878. 



This species is similar to melanota Spangberg in general color. 

 Comparatively more narrow and a smaller species. The elytra are 

 smoky and dark, but have a light spot on costal margin near apex. 



The specimens I have examined were all from New Mexico. It is 

 known to occur in Mexico and Central America.

 Gypona nigra Woodworth, Illinois Lab. Nat. Hist., vol. 3, p. 31, 1896. 



This is one of the darkest colored species in the genus. Specimens 

 as viewed from above often appear jet black. The vertex, pronotum 

 except lateral borders, and scutellum are normally black but often
