times are faded to a yellow. The elytra are entirely smoky and usu- 

 ally dark. 



It is an eastern species and occurs as far west as Colorado. 



20. GYPONA SANGUINOLENTA Spingberg. 



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

 3, p. 63, 1878. 



This is the darkest colored of the species that form the sanguino- 

 lenta Spangberg, scarlatina Fitch, irrorella Spangberg, grisea 

 Spangberg group. The four small dark spots on the elytra are 

 always distinct. The cells of the elytra are interspersed with black 

 dots, and there are normally two dark spots on the pronotum behind 

 the ocelli. The ocelli are comparatively large. The head and 

 vertex may be flaked with red. 



Specimens are at hand from Massachusetts to Florida and west 

 to the Mississippi Valley, 



21. GYPONA IRRORELLA Sp&ngberg. 



Gypona irrorella SpInberg, K. Svenska Vet. Akad. Handl., vol. 5, No. 3, p. 



60, 1878. 



This species has a striking resemblance to scarlatina Fitch, but 

 may be distinguished from it by the fact that the base of the clavus 

 is not darkened, also the vertex is less produced in irreroUa Sp&ng- 

 berg. The species must also be considered closely alHed to grisea 

 Spangberg, from which it differs in being much smaller and having 

 comparatively smaller ocelli. Irrorella Spangberg is normally 

 flaked with red as in scarlatina Fitch and sanguinolenta Sp&ngberg, 

 but is lighter in general appearance. 



It is primarily a southern species, but is known to occur through- 

 out the Central States. It appears to be less common than any of 

 the above-mentioned species. 



22. GYPONA SCARLATINA Pitch. 



Gypona scarlatina Fitch, Homop. New York State Cab., p. 57, 1851. 



The comparatively small oceUi, and somewhat produced vertex 

 will distinguish this from other closely related species. The vertex, 

 pronotum, and elytra may be flaked with red but the elytra lack the 

 black dots as in sanguinolenta Spangberg. Fresh specimens are of a 

 decided brown color with the head appearing somewhat rosaceous or 

 light reddish brown. 



It is a northern species and must be kept as a distinct species until 

 large numbers can be examined when it may prove to be merely a 

 northern form of sanguinolenta Sp&ngberg. Fitch's type has been 

 examined.
