In these notes on the bark-beetles of Istria, it is stated that the 

 galleries of Scolytus (Eccoptogaster) pygmaeus, F., in Ulmus campestris 

 suhcrosa differ from those described by Shevirev, the maternal passage 

 being regular and larval passages radiating rather straight to the sides. 

 PhJoeophtJiorus brevicoUis, Kol., which has so far been reported only 

 from the Caucasus and the Crimea, was found on Colutea arborescens. 

 P. latus, sp. n., a large dark species, occurred on Spartium. junceiim. 

 Phloeosinus serrifer, sp. n., which is related to P. thujae, was found on 

 Cupressus sempervirens and Juniperus communis. Kissophagus 

 erinacellus occurred in Corfu. Liparthrum colchicum, Sem., was found 

 on Laurus nobilis ; this species has hitherto only been repiorted from 

 the Caucasus ; its eggs are destroyed by the mite, Notaspis alatus^ 

 Herm. L. albidum, sp. n., was found on Spartium junceum. Pityo- 

 'phthorus carniolicus, Wichm., infests Pinus austriaca. 



This paper is completed by a supplement by F. Ruschka on Hymenop- 

 terous parasites reared from the above bark-beetles. These include 

 theBraconid, Ecphylus caudatus, sp. n., attacking L. colchicum, and the 

 Chalcid, Wichmcmnia decorata, gen. et sp. n., from stalks of Spartium 

 junceum infested with L. albidum.
