out again, and, unal)le to find water, retained their eggs until they 

 hatched in the body, but the speed with which this happened hardly 

 agrees with the idea that, if laid in water, they would have taken 

 " six or seven months to hatch." 



I shall be much obliged by information as to name. Are Cloe 

 bioculata and Glocon dij^terum synonyms ? I notice that Miall in 

 his 'Natural History of Aquatic Insects' gives the name as Chloeon 

 dipterwn. When Doctors and Professors differ, where does the 

 poor student come in ? — William Harvey; Eastbourne, July Stii, 

 1910. 



Parasites of Callophrys rubi. — In the July ' Entomologist,' 

 Dr. Chapman, when recording the breeding of an ichneumon from 

 this species, quotes Mr. Claude Morley as saying that it " is the 

 first parasite ever bred from Thecia nibi, so far as I am aware." Mr. 

 Morley was probably thinking of hymenopterous parasites only, as 

 dipterous parasites have been recorded. Brauer and von Bergans- 

 tamm in the * Zweifliigler des Kaiserl Museums zu Wien,' part vii., 

 p. 72, give Exorista confinis, Fall, and Exorista tritcBniata, Rond. ; 

 and Mr, Verrall has a specimen of the latter species, the laconic 

 label of which reads — if I remember rightly — " ex rubi Barrett." —

British Scorpion-Flies. — I have paid but scant attention to 

 this group of insects, but Mr. Lucas's note in the last number 

 induces me to send you the following jottings from my collection, 

 which is named by McLachlan and Morton. Panorpa communis 

 occurs in Suffolk from May 21st, through June to July 5th (once on 

 July 26th) ; it is abundant, but I have never seen it with prey, always 

 sitting on bushes or swept from herbage at Bentley, Barnby, Assington, 

 Southwold, Henstead, Lavenham, Stanstead, Barham, Woolpit and 

 Monks Soham. Helpston Heath, near Peterborough, June 13th, 1908. 

 On July 2nd, 1910, I saw one in my garden here, sucking blackberry 

 flower and standing vertically in it; on August 8th, 1901, I took one 

 sucking Angelica flower at Matley Bog, New Forest. Panorpa ger- 

 manica occurs in Suffolk from May 11th to June 14th only (though 

 once on August 24th) ; it is common, but I have never seen it with 

 prey, always sitting on bushes or swept from herbage at Bentley, 

 Bramford, Henstead and Assington. Helpston Heath, near Peter- 

 borough, June 13th, 1908 ; Knight Wood, New Forest, June 14th, 

 1907. Panorpa cognata is very rare, and I have but once met with 

 it ; two specimens were beaten from alder bushes in Barnby Broad, 

 Suffolk, along with P. communis, on July 5th, 1906. Of Boreus 

 hyemalis, I possess but a single female, given me some years ago by 

 Mr. Albert Piffard, who took it at Felden, Boxmoor, Herts ; it cer- 

 tainly does not occur about Ipswich, whence I have examined cart- 

 loads of moss and debris, and I should be surprised to learn that it is 

 to be found at all in tlie Eastern Counties. — Claude Morley; Monks 

 Soham.
