Hylastes (Ufeiiuadifi Er. in Biitain. — ^\'illi rcfereiicu to Dr. .Sharp's 

 addition oi Hylastes atienuatus Er. to the British list, the following records of 

 the insect's occurrence in this country are of interest. On May 29th, 1919, 

 I took the species in some numbers on pine-stumps in Knightwood Enclosure 

 in the New Forest. Both light-coloured and mature adults were found, 

 together with larvae and pupae. Ten days later I met with it in the Surreyhill 

 Woods, Bagshot, on Scots pine-stumps, when larvae and pupae were also 

 found. In September, 1919, I again visited the New Forest in company with 

 Professor Hudson Beare, to whom I had sent some of my first specimens, and 

 on this occasion, too, we took larvae and adults in considerable numbers in the 

 same stumps which I examined in May. In June of the present year Hylastes 

 attenuatas occurred in considerable numbers in traps set for the pine weevil 

 {Hylobins) in exj^erimental plots in the New Forest. In Juiy, in Cumpanv 

 witli my colleague, Mr. Guillebaud, I found the species at Oxshott, Surrey, 

 and later in the same area I captured further examples when with Mr. Laiug, 

 as Mr. Champion has stated. I have also taken it on recently-planted Corsican 

 pine in Hawkliill Enclosure, near Brockenhurst. It is of interest to note that 

 the late Dr. Niisslin,a leading continental authority on the Scolytidae, regarded 

 H. (inyustatus Herbst as a variety oi H. aiteiiuafus Ev. In his "Leitfaden 

 der Forstinsektenkunde " (2nd Edition, 191o) he states " Wir treiineu H. an- 

 (fustatus Ilbst. artlich uicht von attenuatus Er. ab." On the other hand, 

 lleitter in his " Bestimmuugstabellen der Borkenkafer " (Wien. Ent. Zeitschrift, 

 191 8, Heft 4) recognises two species, which he regards as highland or sub- 

 alpine insects. It is also noteworthy that in Central and Southern Europe 

 //. attennatus is regarded as the commoner and more injurious species, while 

 //. (mytistafus is considered rare. With regard to Dr. Sharp's record of spruce 

 as the beetle's host, it may be worth stating that in Central Europe H. at- 

 tenuatus occurs on spruce and Scots pine indifferently. — J. W. Munro, 

 Entomologist, Forestry Commission, Royal Gardens, Kew : October "itJi, 1920. 



Cryphalus {Ernoporiis) fayi Kordm. in Surrey, etc, — The records of the 

 occurrence of this bark-beetle in Britain are sufficiently few to make an 

 additional one of interest. On October 3rd last I observed on a dead branch 

 of a beech-tree near Kew the tiny exit-holes of a bark-borer, and on barking 

 the branch I obtained the remains of several Cryphalus fayi. On the 6th 

 I obtained from further branches a number of perfect but dead specimens, and 

 on the 10th further search in the locality yielded living beetles on dying 

 and dead suppressed branches. In the attacked branches the irregular linear 

 egg-tunnels of the beetles were distinct in the sap-wood. They varied in 

 length and direction, but usually lay along the branch or twig, forming 

 moderately deep gi'ooves in the sap-wood. The larval tunnels were also cut in 

 the sap-wood, but were at tii'st indistinct. The pupal chambers were cut deep 

 in the sap-wood, in small twigs penetrating the pith, or consisted of small 

 excavations roofed over with fine compressed dust. The exit-holes of the 

 beetles in the bark were remarkably clean cut and circular. The branches and 

 twigs attacked varied from 3 inches to ^ inch in diameter. I have also found 

 it on several occasions in the Mark Ash Enclosure in the New Forest, in M.av 

 and September 1919, and June 1920. Mr. Champion's record from Guildford 

 is the only other Surrey capture known to me.— J. W. Murmo.
