AN EXPEDITION TO MOUNT BATU LAWI. 95 
have the support of Dr. Ris, a slight alteration becomes necessary 
in the definition of the genus pr oposed by Wilhamson, namely that 
the anal field of the front wing may consist of a single row, or of a 
maximum of two rows of cells. 
Hylaeothemis clementia, Ris. 192 Limbang. 
Described from a single male in the Selys collection. Length 
of abdomen 2 23mm. 4 23 mm. , hind-wing Q@ 27mm. ¢ 25 mm. 
In coloration the female is practically identical with the male 
described by Dr. Ris. The eighth abdominal segment has well deve- 
loped lateral foliations. The ventral plate of this segment ends at 
the level of the end of the segment in a pair of blunt ‘almost s square 
projections one on either side of the middle line, with a median 
notch between them. ‘The ventral plate of the ninth segment has 
posteriorly a slight median rounded projection which at its free 
margin is fringed with rather stout hairs some of which project 
downwards (see fig. 3). Except that segment 8 has well marked 
lateral expansions the arrangement of the terminal segments of the 
abdomen resembles very closely that figured by Dr. Ris for the 
African Allorhizucha klingi, Karsch. Ris remarks that the struc- 
ture of the genital armature of the male Hylaeothemis allies it to 
the group of genera to which Allorhizucha klingi belongs. Mr. 
Moulton’s specimen has only two nerves on the basal space of both 
hind wings and the supratriangular space of the right fore-wing 
is uncrossed. 
CALOPTERYGINAE. 
Matronoides cyaneipennis, Forster. 
Six males of this magnificent insect were obtained by Mr. 
Moulton from a mountain torrent which flows between Mt. Selin- 
guid and Batu Lawi at an altitude of about 3,800 ft. This is a 
new locality for the species hitherto recorded only I believe from 
Mt. Kina Balu. The single specimen belonging to the genus 
Huphaea is a female, and at present it is unfortunately impossible 
to determine the species of isolated females of that genus. 
The Rhinocypha belongs to a species of which the description 
has not yet been pub lished. Mr. Martin however, has already 
named and described speciznens belonging to the same _ species, 
in his volume on the Calopteryginae of the de Selys collection, 
which is now in the press and shortly to be published. Accor dingly 
I pass it over here. ;
