material, but on further examination the difference in tliis res]>ect appears 

 to be unimportant. 



[It may be mentioned here that Ischnura musa Bartenef is 

 closely allied to I.forcipata Morton (Trans. Ent. Soc. Lond. 1907, p. 306) 

 if it is not the same species.] 



Evans reports, 27.V.18 : "Only examples of this form have been 

 seen lately " (/'. e., no I. evansi) ; " most of the females are much redder 

 than before." 



S.ix.lS : Has almost gone now ; only an occasional straggler of 

 small size being found ; any females seen are of the rufous-sided sort." 



4. — Lindenia tetrnphylla Lind. 



At Amara this fine insect was first seen on May 6th (two only, 

 one 5 taken) along with Anormogomphus about barley-fields inter- 

 spersed with succulent Suaedas, on a salty clay baked hard ; not near 

 the river. Specimens all dated May, from 6th to 22nd ; $ $ 6th and 

 11th teneral with imperfectly developed hind wings. A S dated 11th is 

 fairly mature, and the majority of those taken afterwards up to 22nd, 

 matm*e {Evans). Taken also by Buxton at Qurnah, R. Tigris, May 17th 

 ( 2 $ ) ; and at Hamar Lake, R. Euphrates, May 18th ( J d , $ ? ), 

 all fully mature specimens. 



No exact indication of the duration of this species bej^ond Captain 

 Evans's remark, 5.ix. 1918 : " I have seen none for some time." 



5. — Anormogomphus kiri'tshenkoi Bartenef. 



First taken at Amai-a along with L. tefraphylla. May 6th, 1918 ; 

 the majority of the specimens taken up to the 14th of that month not 

 quite mature. On September 5th Evans reports : " Still frequent, but 

 not so abundant as it was about a month or so ago. It has been very 

 common throughout the summer chiefly in dry places about gardens, 

 but occurring almost everywhere." Also taken by Buxton at Amara, 

 6 May 28th, $ June 10th ; and at Qurnah, May 17th {6 6). 



There appears to be no doubt that this Gomphine from Mesopotamia 

 is the same as the above-named species, described by Bartenef from 

 Bokhara (Revue Russe d'Entom. xiii, 1913, No. 1, p. 179, figs. 1-4). 

 It is closely allied to A. hete7'opterus Selys, from India. The nem-ation, 

 however, seems closer when compared with Williamson's figvire of the 

 wings of A. heteropterus (Proc. U.S. National Museum, vol. xxxiii, 

 p. 299), and the character in the Key (p. 275) "one row of cells
