382 THE CANADIAN ENTOMOLOGIST. 



Ceresa patruelis, Stal. 

 In the collection of the Museum of Comparative Zoology at Cam- 

 bridge are examples of this species from Mexico and Florida, which 

 convince me that this is a good species quite distinct from testacea, Fairm., 

 of which the same museum has a series from Mexico and Guatemala. 

 Ceresa patruelis is larger, the pronotum is higher, the supra-humeral horns 

 are longer and more elevated, leaving the metopidium more concave 

 transversely than in testacea, and the last ventral segment of the female is 

 very short, with a broad shallow notch. 



Ceresa testacea is a smaller and darker species, with the edge of the 

 pronotal carina slenderly fuscous and the last ventral segment of the female 

 longer and more deeply and triangularly notched almost to its base. 



The Ha Godingi x Van I). 

 There is a specimen of this species in the Fitch collection under the 

 name univittata, Harris. A specimen of the latter species in the Harris 

 collection shows my former determination to be correct. 



Telamona fagi, Fitch. 

 An examination of the type in the Fitch collection shows it to be but 

 a slight variation of cristata, Fairm., and not identical with scalaris, Fairm., 

 as supposed by me. Infogi the colour is more fuscous and the anterior 

 foliole is less developed, but I cannot consider it a distinct species. 



Telamona concava, Fitch. 

 The type in the Fitch collection agrees in every respect with the 

 species as recognized in my studies in North American Membracidae. 



Telamona fasciata, Fitch. 

 An examination of the Fitch type shows this to be a male, as 

 suggested by me in Psyche (V, p. 391, 1890), and the synonymy of my 1908 

 list must stand. 



Telamona tristis, Fitch. 

 The type of this species in the Fitch collection is a female, as indi- 

 cated by Dr. Fitch. The crest is shorter and higher than in coryli, and it 

 is perhaps specifically distinct. I have recently taken a dark female of 

 coryli on the hop horn-beam. 



Car y not a arcuata, Say. 

 Under this name in the Fitch collection is a specimen of an 

 Ophiderma, probably salamandra, Fairm. I noticed the same erroneous 

 determination in the Harris collection.
