limhatus F., in the usual fungus on birch ; Triplax aenea Schall., and 

 its larvae in abundance \\\ fungus growing on old holly ; Pterostichus 

 ohlongo-punctatus F., more metallic in colour than New Forest 

 specimens, in fallen boughs ; Taphria nivalis V&nz., Stomis pumicatus 

 Panz., and Liophloeus mihilus F., crawling on roads. By evenino- 

 sweeping in one of the numerous beautiful glades, we captured Brady- 

 celhis harpalinus Dej. in great numbers, Anisotoma calcarata Er., 

 Eoco)nias araneiformis Schrank, Ilalfliodes marginatus L., Malthinus 

 piincfatus Fourcr., and Apliodius zenTceri Germ. Under the bark of 

 dead standing oaks, the larvae of Bliagiiim inquisitor F., R. hifas- 

 ciatiim F., and Pyrochroa coccinea L., were very abundant. 

 The Saw-fly Sirrx cyaneus Pz. occurred in a felled beech. 

 We were evidently visiting the forest at a time somewhat between 

 the seasons for most insects. 



With regard to T. erosns, it is desirable to draw attention to what 

 appears to be a mistake made by Heitter and other continental writers 

 in regard to an important character connected with the antennae of this 

 species. JMr. D. J. Atkinson in introducing this species (Ent. Mo. Mag. 

 1921, p. 253) stated that the sutures of the club of the antennae were 

 curved, while in laricis they were straight. A careful examination of 

 our specimens of erosus and of the specimens of laricis we took and 

 mounted showed that this was so ; on the other hand, Reitter (Fauna 

 Germanica, vol. v, p. 303) divided the genus Ips = Tomiciis into two 

 sub-genera, the one Ips s.s., having curved sutures on the antennal club, 

 the other, Orthotomicus, having straight sutures on the club, and he 

 places erosus in his second sub-genus along wdth laricis, suturalis, 

 proximus, and longicolUs ; this is evidently an error. That our insect 

 is true erosus is proved by the fact that Mr. Atkinson (/. c.) compared 

 his specimens with Wollaston's types from Madeira, now in the Natural 

 History Museum. We have looked up Wollaston's original description 

 (Catalogue of Madeiran Coleoptera, 1857, p. 95), and the characters 

 given by him to separate erosus and laricis are those we find in our 

 specimens, although Wollaston says nothing about the antennal club 

 sutures. 



The insect was first taken under bark of chestnuts in Madeira ; 

 Reitter says it occurs under bark of Pimis mar it i ma in South Europe, 

 North Africa, Syria, Armenia, and the Cavicasus ; it is evidently not 

 confined to any one species of tree, as will be seen from the above 

 records, and the fact that it occurs in Scots pine in Great Britain.
