1920] Ball: Review of the Genus Gypona 97 



black spot in both sexes. The males sometimes have the two 

 median black points on pronotum and a few on disc of elytra. 

 The head is similar to that in citrina, but shorter with the margin 

 even more rounding in some examples. 



Spangberg described this form from Texas and gave its 

 color as greenish yellow with a brown appendix. He compares 

 it to flavicosta Stal, which has a very short head. Gibson 

 placed this name on a reddish form apparently common in 

 Maryland and New Jersey (see var. rodora) and described the 

 true meditabunda as cacozela and again as occlusa, but separating 

 them in the key by the absence of the spot on hinges in cacozela, 

 but in the descriptions he gives "elytra with base of clavus 

 darkened" in both cases. As has been shown above, this 

 character is widely variable. All the examples of this form 

 seen have been from Texas. The writer has three examples 

 from Brownsville and one from San Diego, Texas, while all of 

 Gibson's material was from Brownsville. 



2. Gjrpona (Ponana) curiata Gib. 



A small, dull brownish species with blunt head, faint mark- 

 ings on elytra and the nervures bordered with fine punctures. 

 Gibson's material was from Arizona. 



3. Gypona (Ponana) dohmi Stal. 



Gypona punctipennis Stal.; (?) Gypona bisignata Fowl.: (?) Gypona reservanda Fowl.; 

 Gypona aquila Gib. 



A long, slender testaceous or grayish brown species super- 

 ficially strikingly resembling Phlepsius majestus Osb. and Ball. 

 The front is transversely lined with brown, the vertex is almost 

 parallel margined, the ocelli are before the middle and twice 

 farther from each other than from the eyes. There are black 

 spots behind the ocelli, pot-hooks and spots on the anterior 

 sub-margin of the pronotum. The elytra are long, narrow and 

 inscribed with fuscous marks in the cells, with one or two larger 

 ones behind the middle, while the nervures are margined with 

 fine fuscous dots. 



Examples are at hand from Grand Junction, Colorado, the 

 Huachuca Mountains, Arizona, and Stal described it from 

 Mexico. It is probably confined to the Rocky Mountain 

 region. Fowler did not recognize either of the Stal species, but 

 apparently described it twice.
