This species belongs to a distinct group, which includes also 7! heiKjlini and 

 T. evarjore. 



Dr. Butler and Mr. Guy Marshall agree fairly well concerning the synonymy of 

 this species, excepting that the latter gentleman considers T. demagore to be identical 

 with T. ejjJii/ia instead of with T. daira, and T. noiiiia to be the same as T. evni/ore. 

 Dr. Butler tells me that he now regards T. stj/r/ia as identical with T. daira, and ho 

 believes that the latter is really identical with T. liagore, which I have placed as a 

 synonym of T. evarne {vide antea, p. 90). In this I followed Dr. Butler's latest arrange- 

 ment of the genus; and if T. liaijore really belongs to the T. daira group, and is 

 identical with the last-named species, then the latter name will have to be suppressed 

 and that of T. liar/ore adopted. 



The type of T. stip/ia of Felder, from Bogos Land, has been kindly lent to me by 

 the Hon. Walter Rothschild ; it is, according to Dr. Butler, an " intermediate 

 seasonal " form. I agree with Dr. Butler that it is identical with T. daira, and he has 

 since identified several specimens in the British Museum from Zeila, collected by 

 Capt. Nurse, as being T. ^Iip/w, and not to be separated specifically from T. daira. 

 Again, owing to Mr. Rothschild's kindness, I have been able to examine all the 

 Felder types, and I find that T. demagore is a very " dry " form, having the black 

 apical spots more distinctly indicated, also a gre}' dusting along the inner margin. 

 The s])eciniens in the National collection do not quite agree with the type. 



Dr. Butler writes : " The type of Felder's T. duhla is identical with the typical 

 wet-season form. T. odysseiis is an intermediate form, and T. noinia (of which 

 ■ T. demaffore is a synonym) is the dry-season form. Tlie latter, owing to its 

 resemblance in the male sex to the dry-season forms of two other allied species, 

 has been united to them and placed in the next group of species by Mr. Guy 

 Marshall." 



Mr. Guy Marshall observes: 'The male seems to hold an intermediate position 

 between T. i/erhiirii and T. thrnjqni, but the female is very distinct froin that of any
