Genus 2. Sph.enogona, Butler*, 

 Cist. Ent. iii. p. 44. gen. 15, pi. 1. f. 13 (1870). 



1. Sph.enogona gratiosa. 



Terias gratiosa, Hewitson, Gen. Diurn. Lepid. pi. 9. f. 5 (1847). 

 Venezuela. B.M. 



2. SpH/ENOGONA ecuadora. 



Terias ecuadora, Hewitson, Equat. Lep. p. 2. n. 2 (1869). 



Ecuador ( Buckley}. 



A beautiful species allied to 5. gratiosa. 



3. Sph^enogona ingrata. 



Terias ingrata, Felder, Verh. zool.-bot. Ges. Wien, p. 465. n. 1 

 (.1869). 



Terias gratiosa, Reakirt, Proc. Ent. Soc. Phil. ii. p. .359. n. 3 

 (1863). 



Mexico; Chontales ; Nicaragua; Polochic Valley. B.M. 



4. Sph^enogona xantochlora. 



5 • Terias xantochlora, Kollar, Denkschr. Akad. Wiss. "Wieu, 

 math.-nat. CI. i. p. 363. n. 36 (1850). 



c? . Terias bogotana, Felder, Wien. ent. Mon. v. p. 84. n. 41 (1861). 



Terias chloe, Felder, Reise Nov. Lep. ii. p. 199. n. 202 ("1865"). 



Terias gaugamela, Felder, /. c. n. 203, pi. 26. f. 5 ("1865"). 



Bogota. 5 c?, B.M. 



The above species described by the Felders appear to me to be 

 identical with T. xantochlora. 



5. Spblenogona limoneus. 



Terias limoneus, Felder, Wien. ent. Mon. v. p. 84. n. 43 (1861) ; 

 Reise Nov. Lep. ii. p. 200. n. 204 ("1865"). 

 Venezuela. 

 Seems nearly allied to S. xantochlora. 



6. SPHJENOGONA SALOME. 



Terias salome, Felder, Wien. ent. Mon. v. p. 84. n. 42 (1861); 

 Reise Nov. Lep. ii. p. 201. n. 206 ("1865"). 



Ecuador {Felder) ; Bolivia. B.M. 



Dr. Felder says of this species, " The only male in our collection 

 is larger than T. constantia just described ; the wings are as broad 

 as in T. xantochlora, Koll., and the hind wings more distinctly 

 angulate." 



7. Sphjenogona jamapa. 



$ . Terias jamapa, Reakirt, Proc. Ac. Nat. Sci. Phil. p. 239. 

 n. 5 (1866). 

 Mexico. 



* The type of this genus is an undescribed species from Archidona, allied to 

 ■S. constantia, £ , Felder ; Doubleday gives Quito as the habitat, but we have no 

 species of this group from that locality.
