NOTES ON BRITISH THYSANOPTERA. 27T 
On June 25th a Thrombidiid mite, Actineda vitis, Schrank, 
was found on infested peas carrying a larva of the pea-thrips 
which it was sucking. Mr. S. Hirst, who kindly identified the 
specimen, tells me that itis a predaceous mite generally common, 
on miscellaneous plants. 
I was also able to feed larva of the predaceous thrips A¥¢olo- 
thrips fasciatus on larve of the pea-thrips in captivity. One 
larva of A. fasciatus sucked and killed three larve of K. pisivora 
in about threehours. Ihave found both adults (commonly) and 
larve (occasional) of this species in pea flowers but have not. 
actually seen them feeding on the pea-thrips in the wild state. 
There is little doubt, however, that they do so as the species is 
normally predaceous and is indeed the chief enemy of Limothrips 
cerealium, an abundant species which occasionally damages. 
corn. 
In recording the distribution abroad of K. pistvora in my 
previous account (loc. cit.) I overlooked the record of Schille 
(‘Ent. Zeitschr.,’ 1912). He mentions having taken the species, 
not common, in flowers of Hchiwm vulgare, Orchis, Rosa centifolia 
and Pisum saccharatum at Rytro im Popradtale, Galicia. 
In addition to the above flowers which are all new to the list. 
I have already given, I have taken the species in the flowers of 
the yellow melilot (Melilotus officinalis). 
Odontothrips loti, Haliday. 
This species, which occurs in the flowers of Lotus corniculatus 
in England, is quite distinct from O. ulicis, of which it has recently 
been considered a synonym. In O. loti the wing is dark except 
at the base, but there is a slight though distinct fading of the 
dark area from the base outwards, whilst in O. wlicis the dark 
colour is uniform throughout the outer part of the wing. In 
O. loti the teeth on the apex of the fore-tibiz are both abbreviated, 
the internal one very short and bearing a short spine at the tip, 
the external one a little longer and bent downwards. In O. ulicis 
both are much longer. 
Teniothrips primule, Haliday. 
On April 19th, 1914, this species was abundant on the flowers 
of primrose in the New Forest, Hampshire. The females largely 
outnumbered the males. A random collection consisted of sixty 
females and five males. Specimens brought home were placed on 
potted primrose plants and immediately started laying eggs. 
The eggs were embedded in the prominent ribs on the underside 
of the leaves, chiefly the midrib, in the flower-stalk and in the 
ribs on the calyx. The abdomen is first curled up in an inverted 
U and the tip of the ovipositor applied to the plant surface, the 
abdomen is then gradually straightened and the ovipositor, which 
finally becomes at right angles to the body, is forced into the
