incomplete, being without the head. It is evidently very closely 

 allied to C. nigrohamata, but differs in the following respects. 

 Segment 8 of the abdomen has its terminal quarter ringed with 

 blue, the blue mid-dorsally has its margin indented with black. 

 The upper anal appendages care brownish black, more abruptly 

 truncate than is the case in C. nigrohamata, and distinctly 

 though very little longer than the lower pair. The lower pair 

 are relatively stouter than in C. nigrohamata, and are brownish 

 yellow (probably blue in life). 



The three species, C. macrostigma, nigrohamata, and that to 

 which this male belongs will probably constitute another distinct 

 section of the genus Coeliccia, characterized by small size, rather 

 dense reticulation of wings, as opposed to the open venation of 

 C .flavostriata ; by the shape of the upper anal appendages of the 

 male ; and probably by the prothoracic structure of the female. 



To this group I believe it will be found that the species called 

 Trichocnemis octogesima albicauda by Forster (which I suggest 

 should be named C. albicauda (Forst.)), also belongs. 



Cceliccia membranipes (Ramb.), race nemoricola Laidlaw. 



C. nemoricola Laidlaw, Journ. R. Asiat. Soc. Str. Br. no. 63, 

 p. 95 (1912) ; id. Proc. Zool. Soc. London, 1915, p. 37. 



T have re-examined the examples of this form from Mt. Kina 

 Balu, and have come to the conclusion that they may fairly be 

 taken as representing a local race of the widely-spread G. mem- 

 branipes (Ramb.). The character most readily employed for 

 separating males of nemoricola from the typical membranipes is 

 afforded by the colour of the upper anal appendages, which are 

 blue in membranipes, black in nemoricola. 



The Kina Balu specimens show marked variability in size and 

 in ven ation. 



Measurements of 5 males taken at random from amongst the 

 15 male specimens that I have received from Mr. Moulton are as 

 follows : — 



Length of abdomen 47 mm., 43 mm., 41 mm., 45 mm., 45 mm. 



,, hind wing 30 mm., 28 mm., 26 mm., 30 mm., 30 mm. 

 The number of postnodal costal nerves ranges from 16 to 21. 

 The point of origin of M 3 and Rs varies greatly, as shown in 

 the following table taken from the same males.
