BAGNALL'S THYSANOPTERA 7 



possible that large specimens such as the Eupathithrips affinis holotype might be 

 recovered when they are needed, but small specimens such as Baliothrips biformis 

 have degenerated too much. Some of the species listed below as missing may have 

 been lost by Bagnall himself in attempting to remount from such blackened slides. 

 The mountant may have been a mixture of balsam in chloral hydrate and phenol, as 

 this has recently been shown to have the same behaviour. 



Carded specimens. Bagnall described many species from dry specimens mounted 

 on cards, although this is not always clear from the description. Some of these 

 specimens were seriously damaged by fungus. In a few cases the insect was covered 

 by a network of hyphae, a spectacular condition which was not found to be as serious 

 as an internal fungal attack destroying the intersegmental membranes. The 

 external hyphae have now been dissected free and the specimens removed with the 

 loss of only a few setae in many cases, but internal fungal attacks left several speci- 

 mens excessively fragile. About ioo specimens, mainly types, have been removed 

 from cards and mounted in balsam although some of these are seriously damaged. 



Specimens in tubes. Several hundred tubes were received from Bagnall by the 

 British Museum. Most of these are still unclassified. They are dry, often without 

 labels, but in some cases contain the remains of series from which species were 

 described. Preliminary sorting has not disclosed any of the species listed below as 

 missing. 



Labelling of specimens. Data on the slide labels has been checked with the 

 published data for each species. Unfortunately Bagnall sometimes did not write the 

 collection data on the slides and in the text below this is indicated by enclosing such 

 data, and any other information, in square brackets.
