tissue. ‘The end of the body is then worked up and down and 
the hole made by the blades of the ovipositor enlarged. This 
rocking movement continues with short intervals of rest during 
the whole time that the ovipositor is inserted into the plant. 
At no time during the process was the egg, which is compara- 
tively very large, seen to pass bodily into the plant, and it is 
quite probable that it ‘‘ flows’ in in a manner similar to that 
described by Chapman (‘ Trans. Ent. Soce.,’ 1914, p. 178) for 
sawflies. 
The time between the first insertion of the ovipositor and its 
withdrawal varied in several timed observations from 1 min. 
‘20 sec. to 2 min. 40 sec. The female proceeds, after a rest, to 
move a short distance and lay another egg. One female was 
observed to lay five eggs in fifteen minutes. 
One female shows ten fully-developed eggs in its abdomen, 
the most anterior being partly in the thorax. It is probable 
from this that the eggs mature in batches, and that those of a 
batch are laid close together. Most other species of thrips, 
-however, only mature one or two eggs at a time, and lay at 
short intervals over a long period. 
The eggs are of the normal kidney shape, and are laid with 
‘the posterior end more deeply embedded than the anterior, 
which is usually quite near the surface. They are nearly always 
laid with their long axis parallel to the length of the stalk or 
rib in which they are laid. They are about 0°33 mm. long by 
0°2 mm. broad. By May 8rd several of the eggs (the first of 
which were laid on April 20th) hatched, giving a duration of 
thirteen days for the egg stage. By May 25th one of the larve 
was almost full fed, and shortly after this, I believe, entered 
the ground. The subsequent history of the species is still 
uncertain, but the occurrence of three females in flowers of 
woodsage (J'eucrium scorodonia) at Box Hill, Surrey, on July Ist, 
1914, and one female hibernating in moss in the New Forest 
on November, 1913, indicates that probably the larve from the 
primroses in the spring would reach the adult stage the same 
year, and may possibly produce a second generation in other 
flowers. 
Besides the above records I have the species from the Isle 
of Man (April, 1912) and from Cockermouth, Cumberland, in 
the flowers of primrose (Primula vulgaris) and cowslip (Primula 
vers), 
Teniothrips inconsequens (Uzel) (= Teniothrips pyri, Daniel). 
I have long considered that Physopus inconsequens, Uzel, 
was closely related to J'eniothrips pyri, Daniel. I have now 
had,the opportunity of comparing specimens of inconsequens 
from the collection of Dr, Uzel with both American and English 
pyri and can find no important difference between them. The
