FASCICULI MALATENSES 
LEGION PLATYCNEMIS 
Trichocnemis renifera. Selys (race ?) 
I $ , 3 $ . Bukit Besar. 2,500 feet. 
The male and two females were taken in May, the third female, which is 
very immature, in August. Unfortunately, the head of the male specimen 
has been damaged. This sex has not been fully described so far as I am aware. 
de Selys [’86] merely remarks that it differs from T. didyma chiefly in size 
and in having more extensive black marks on the head. The following are 
some other features distinguishing the present specimen from the male of 
T. didyma. The anal appendages are black ; the upper pair are rather longer 
than the lower, and are provided with a small ventral sub-median tooth ; their 
distal ends are widened dorso-ventrally. The lower pair are directed upwards, 
and at their extremities are hooked downwards. The black line at the second 
lateral thoracic suture is not continued down to the second .femur. 
The females tally closely with that described by de Selys ( loc . cit.) from 
Darjiling so far as the head and thorax are concerned, but differ in having the 
tenth abdominal segment entirely black ; whilst apically on segments eight and 
nine, which are also black, there is a dorsal, crescent-shaped, yellow mark. 
Length of abdomen, $ , 4.5 mm. ; 9 , 40 mm. 
Length of hind wing, $ , 26 mm. ; 9,27 mm. 
This species has very recently been recorded from Tonkin by M. Martin 
L : ° 4 ]. 
It is evidently closely related to the next form. The chief differences 
are in size, this species having its wings considerably smaller ; and in the 
colouration of the thorax of the male. The large spherical mark on either 
side of the middle line should serve to distinguish it when contrasted with the 
‘ keilfOrmiger Fleck ’ of T. orang. Also the legs ol the male have their lateral 
surfaces yellowish excepting for the tarsi which are all brownish-black.

GehOrt zur Gruppe der Platycnemis mit nicht gezahnten FlQgelrande 
und langem Sector inferior trianguli, bei welcher die vordere Seite des Vierseits 
kaum zwei Drittel so lang ist als die hintere. Sie unterscheidet sich von den 
kleinen Arten dieser Gattung wie folgt : Flilgel deutlich vor der basalen 
Submedianquerader ‘ gestielt,’ der Sector inferior trianguli vor dieser Querader 
entspringend. Vielleicht bildet sie mit den Species der II Abteilung (nach 
de Selys. T. didyma) eine besondere Gruppe.
