great plenty if the sun shone, and on a calm day it was quite 
possible to get five or six in the net at once. C. pinetellus and 
C. inquinatellus also sheltered in the fir trees, whilst a few 
S. coniferana and E. atricapitana were to be had, the latter 
having evidently flown up from the ragwort beneath. Altogether 
we brought back some six or seven hundred good insects apiece, 
which was excellent work for three weeks of thoroughly bad 
weather. 
KAKOTHRIPS, wn. aun., A DIVISION OF THE GENUS 
FRANKLINIELLA (THYSANOPTERA). 
By C. B. Wintiims, B-A., F.E.S. 
Durine the past two years I have been investigating the 
life-history of a species of Thysanoptera which does considerable 
damage to peas and beans in this country, with a view to finding 
some method of control; and a full account will be published 
shortly (Annals of Applied Biology). The species has been known 
up to the present by many different names :—Thrips pisivora, 
Physopus robusta, Euthrips robusta, and Frrankliniella robusta, 
the latter being at present the most correct terminology. The 
species has never been properly described, Uzel’s original 
description (‘‘ Physopus robusta,” Monographie der Ordnung 
Thysanoptera, 1895, p. 104) being insufficient for modern 
demands. In making a careful examination of a number of 
specimens for a proper technical description (which will appear 
in the above-mentioned paper) I found that this species differs 
in several respects from all other known species of the genus 
Frankliniella. Uzel (l.c.) had already noted that the male of 
this species has a pair of processes on the abdomen, one on
