Aphids in December. Neither was it discovered what kind of individuals the pro- 
geny develop into, but with them or a little later, about the third week of February, 
several winged males were secured in the chimneys, and on Cynodon in the garden. 
As males of this species have never been collected before a short description is given 
here. 
Alate male.—The alate male is a slender, attenuated, shining, dark-reddish, 
almost black insect; the usual type of genital armature is conspicuous at the anal 
end. 
Head rather broad, quite black, with dark red eyes. 
Antennae about the same size as those of the alate viviparous female, but the 
joints appear thicker, more rounded, and separated from each other by hyaline 
arthrodial membranes. :

The spur is only slightly smaller than the base. 
Sensoria as is usual in the males; the joints are studded over on all sides by 
sensoria of various sizes; the 3rd bears about 45, the 4th about 18 and the 5th 
about 13. None are present on the sixth, except the primary sensorium with its 
group of smaller ones. 
Prothorax distinctly marked by a broad line anteriorly and provided with lateral 
tubercles. 
Mesothorax large, shining black. 
Wings normal, on account of the narrow body they appear relatively voluminous ; 
otherwise their actual size is even smaller than those found on larger alate viviparous 
females. The membrane appears more smoky as a whole; the stigma and veins are 
brown. 
Abdomen long-oval, thin, the breadth here being much smaller than at the 
thorax. Four large circular spots in front of the cornicles at the carinae, with two or 
three black stripes on the segments in front of the cauda. 
Cornicles cylindrical, with vasiform tip, somewhat incrassate about their middle ; 
the size is smaller than those of the alate female. 
Cauda thick, rounded, very much elevated towards the dorsal side, small and 
stumpy looking ; its length is slightly less than the cornicles. 
Anal plate narrow, directed backwards. 
The genital armature consists of a central conical penis; two spiny lateral some- 
what triangular lobes on the sides, meeting in a deep black cresentic line in front. 
Postero-laterally run two blackish hoops; their hind ends curve to touch the sides of 
the penis. 
Legs long and black. 
Rostrum small, reaches half way between first and second coxae,
