Liar ay 
July date of appearance seems to me i eS ONent significance, 
also the fact that no other heathland ponds save the two mentioned, — 
either in this or in previous years, have produced the insect—a 
further surely most significant coincidence. The weather has, of sais 
course, been ideal.—F. H. Hatnes: Brookside, Winfrith, Dorset,

Buoop-suckinc THysANopTeRA.—In corroboration of Mr. C. B. 
Williams’ note in the July number of this Journal (p. 163), I may 
mention that I was bitten by small T’hysanoptera on several occasions 
during my residence in Ceylon. On feeling a small but sharp prick 
one would find the little creature puncturing the skin of the wrist or 
face, but I never allowed one of them to remain long enough to 
distend itself with blood, as described by Mr. Williams. I believe 
that it is recognised that certain species of Thrips are predatory upon 
other small insects. I have found them, for instance, occupying the 
tunnels of Scolytid beetles, where they were almost certainly preying 
upon the larve of the borers. I think it is doubtful, however, if any 
Thysanoptera habitually suck the blood of warm-blooded animals. I 
always regarded such occurrences as in the nature of an experiment 
on the part of the insect, which, finding itself accidentally ‘settled on 
a soft body, automatically sampled the contents. It is conceivable, 
however, that from such small beginnings might be evolved an habi- 
tually blood-sucking race of Thrips.—-K. ERNEST GREEN ; Camberley,

Watkinson, M.A., Woodfield, Hipperholme, Near Halifax.—Mr. 
HK. E. Green, remarking on the early appearance of Lepidoptera this 
season, stated that an example of Xanthorhoé fluctuata had come to 
light on March 12th, while in regard to the hibernation of Pyramets — 
atalanta in Britain—a still debated question—he had observed a 
specimen at sallow on March 17th at Camberley—Mr. C. B. 
Williams exhibited a case of insects from tropical America, including 
a Monadela species of wasp which buzzed only when digging and 
spreading mud, and examples of insects distinctive to sugar-cane.— 
Lt-Col. H. D. Peile, a number of interesting Lepidoptera (Rhopalocera)
