We decided last spring, in view of Mr. Atkinson's capture of 

 Tomicns seccdentatus Boerner and T. erosiis WolL, under bark of felled 

 Scots pine in Dean Forest in August 1921 (Ent. Mo. Mag. 1921, 

 p. 253), to spend a few days in the Forest in August and to explore its 

 possibilities as a collecting ground fronr the point of view of the 

 Coleopterist. 



We left London on August 2nd, and on the following morning 

 were joined by Mr. R. N. Chrystal, who is engaged on entomological 

 research work in connection with the Forestry Commission ; Mr. 

 Chrj'^stal knew the place where Mr. Atkinson had found these two 

 species, but on proceeding to this spot, we found that all the logs had 

 been removed. The greater part of the day was then spent in scouring 

 the Forest in order to find felled timber, and after much ground had 

 been traversed, we eventually discovered a pile of felled Scots pine, 

 oak, etc., and at once saw that the Scots pine-logs harboured T. sex- 

 ileniatas, the large entry and emergence holes being very conspicuous. 

 This insect occurred in abundance in all its stages in thick bark, its 

 parasite Uypophloeus fraxini Kugel., new to the British List, being 

 also found sparingly in the Inu-i'OAVs of the Scolytid. 



During the two days we eventuall}' spent in stripping off the bark 

 of these pine-logs the following other species were taken : — Tomicns 

 erosus Woll., which was by no means common ; MyelopMlus piniperda 

 L., very abundant; Hi/lastes ater Payk., H. opacus Er., N. palliatus 

 Gryll., all more or less common ; Pifj/ogenes hidenfntus Hbst., Hylas- 

 iinns ohscvrus Marsh., rare; Tomicns laricis F., very abundant, its 

 parasite Avlonium rujiicorne 01., new to the British List, was foiuid 

 very rarely in the burrows of this Scolytid. 



In addition to these Scolytids we took, under the bark. Monotonia 

 picipes Hhsi., Spuraea pttsilla Er., TJ. thoracica Tonrn. , ZiaemophJoens 

 ferrnqinens Steph., Enicnnts mintifiis L., Bhizop>h(trn(s dispar Gylh, 

 R. depresses F. (some very large specimens), Corticaria elongata Gyll., 

 Gryptopliayns cylindrus Kies., Honialota cuspidata Er., Typliaea 

 fiimata Curtis (a strange place for this species), and Ernohius 

 mollis L. 



The time spent on this pile of logs left little leisure for general 

 collecting, but the following additional captures were made ■.—Thymnlus
