wing- venation of Antianthe but the other characters are those 

 of Telamona in which genus I believe it should remain. 



15 Telamona unicolor Fitch. PL 2, fig. 6. 



Here the females are light yellow or perhaps at times 

 more or less tinged with green in life, with the extreme tip of 

 the pronotum dusky. Fuscous apex of the elytra strongly de- 

 fined, a little surpassing the terminal areole exteriorly. Crest 

 high, rising almost perpendicularly close to the front of the 

 metopidium, its dorsal edge feebly arcuated, sloping somewhat 

 posteriorly and forming an obtuse angle with the oblique hind 

 edge, highest point at the sharply rounded anterior angle. 



The males are smaller with a shorter posterior process and 

 smaller crest. In color they are very different, being of a 

 creamy testaceous with a vitta on the anterior margin of the 

 crest spreading over more or less of the metopidium, a nar- 

 row, nearly straight, and oblique vitta on the hind margin of 

 the crest which passes down to the lateral margin, and the 

 extreme tip fuscous. This species is found on chestnut trees 

 throughout the northern states. I have taken it in Kansas and 

 it probably occurs west to the Rocky Mountains and in south- 

 ern Canada. 



The male was described as Telamona fasciata by Fitch 

 and again as Hemiptycha diffusa by Walker. Telamona unicolor 

 as figured by Emmons can hardly be this species. 



16. Telamona extrema Ball. 



An interesting species with a still larger crest than in 

 unicolor, and approching mcxicana and cxcclsa. It was des- 

 cribed from Iowa and Kansas but I have seen only New Jersey 

 material. 



17. Telamona collina Walker. 



Described as a Thelia. Butler distinguishes it by its being 

 "much more coarsely punctured than unicolor and with the 

 humeral processes longer and more acuminate." It must, I 

 believe, be near the following species.
