30 THE ENTOMOLOGIST. 
A NEW SPECIES OF PONERINE ANT CAPTURED BY 
; AN ASILUS. 
16; By W. C. Crawuey, B.A. 
In an interesting and extensive collection of African Asilids 
and their prey, made by Mr. §. A. Neave in Nyasaland in 1913 
and 1914, is a number of ants. As might be expected, the 
majority of these are males and females, probably captured by 
the fly during their marriage flight, but there are also a few 
worker forms, all of tree-climbing species, notably Polyrhachis 
and Camponotus. 
Many of the males that are unaccompanied by workers are 
almost impossible to identify, and some of the females are also 
difficult for the same reason ; consequently I have thought it

better to publish first the description of the most interesting 
specimen, as it belongs to a rare and little-known genus. ° 
Promyoptas asilt sp. nov. 
@. L. 71 mm. Mandibles linear, as long as the head, with 
3 teeth at the apex, the apical tooth blunt, the intermediate very 
small and acute, and the inner one acute, larger than the inter- 
mediate, but smaller than the apical; strongly curved from the 
inner tooth for more than half their length, where they form a 
blunt tooth, and from this point to the base they are considerably 
thickened. The clypeus forms a narrow border along the mouth, 
is raised in the middle, and slightly produced in an angle between 
the frontal carine. The latter are short, hardly, if at all, over- 
hanging the clypeus. Head without the mandibles rectangular, 
slightly broader than long, the occipital margin almost straight, 
with rounded angles. The frontal groove reaches the anterior 
ocellus. _ Eyes placed in the fore part of the sides of head, 
occupying the second quarter. The scapes do not quite reach the 
occipital margin, just passing the posterior fifth. The first joint of 
the funiculus only slightly longer than the second, and joints 3-9 
are as broad or broader than long; the last 5 gradually thicken to 
the apex, the apical equalling the two preceding joints taken 
together. Thorax narrower than the head, with unbroken dorsal
