Sel., and several of both sexes of the elegant Megalestes major, Sel., 

 both collected on the 22nd of September 1906. The other one of 

 the three is Bayadera liyalina, Selys, represented by both sexes, 

 from Kurseong, B. Himalayas, 5,000 ft. 



BPHEMERID^. 



The mayflies of the collection were, as is always the case with 

 pinned specimens, in rather dilapidated condition, and not all are 

 determinable. There appear to be about nine species, as 

 follows : — 



Palingenia sp. ? perhaps P. rohusta, Etn. — In absence of figures 

 of the male genitalia, I am unable to be sure about the identity 

 of these specimens; all are in bad condition, more or less teneral, 

 and with crumpled wings. The species will be recognized by the 

 male forceps figured herewith (pi. xx, fig. 8), which is different 

 from the forceps of an}' species that has been figured hitherto. 

 It belongs to the subgenus Anagenesia. (The specimens are from 

 Seistan, Persia — N. A.) 



There are three nymphs of some species of Palingenia 

 collected by Dr. Annandale at Matiana, Simla hills, and sent to me 

 in alcohol. 



Ephemera sp. — A series of specimens in the Lefroy collection 

 from Pusa, Bengal, that at present I do not feel qualified to 

 name; the forceps limb of the male is shown in pi. xx, fig. 9. 



The genus Epeorus is represented b}^ a fragment of a female 

 sub-imago without locality label. 



Chlceon marginata, Hagen. — This species and the following 

 one, hitherto known only from Ceylon, are represented in the 

 collection by a series of both pinned and alcoholic specimens. 

 The specimens are from Calcutta, and from Rajshahi, E. Bengal, in 

 February and December ; from Sylhet in November and December ; 

 sub-imagos and cast sub-imaginal skins are included in the alcoholic 

 material from Rajshahi, where the skins ''were found on the 

 walls of a room of a house some distance from water." 



Chlceon hiniaciilatum , Etn. — This species was found with the 

 preceding by Dr. Annandale at Rajshahi, E. Bengal. The wings 

 of the male are quite hyaline, and therefore I think it is a female 

 that is meant where male is stated in Eaton's Monographic Revi- 

 sion of Ephemeridce ; with that adjustment the agreement of these 

 specimens with those described from Ceylon (p. 182), save for an 

 unnoticed brown spot before the apex of the hind femur, appears 

 to be complete. I figure on pi. xx, fig. 6, the wing of the 

 female, and on pi. xx, fig. 10, the forceps limb of the male. 



There are three small nymphs in alcohol which might belong, 

 so far as I can see, to either one of the two preceding species. 



CcBuis perpusilla, Walk. — Specimens, both pinned and 

 alcoholic from Rajshahi, appear to agree with this insufficiently 

 known species, which was described from Ceylon. It may be
