fortunately been spoilt by drainage operations. It is as a rule very 

 unsatisfactory to bave to describe a new species from a solitary speci- 

 men and it is for that reason that I have withheld publication so 

 long, even now, owing to the fact that the type-slide was slightly 

 damaged in the post, I therefore prefer to regard the above descrip- 

 tion as merely provisional. I have pleasure in naming the species in 

 honour of Lord Avebury. to whose kindness I owe much. 



Aptinoihrips rufa, Gmel., var. connaticornis, Uzel. 



This variety differs from the type in having the three apical an- 

 tennal segments connate, thus forming a single joint. Winlaton 

 Mill, Co. Durham. 



Aptinothrips nitidula, Hal. 



A very small form described by Haliday in 1836 (Ento. Mag., 

 vol. iii, p. 44G) which does not seem to have been met with by any other 

 naturalist. In July of this year I found the species on the Arran 

 coast, where it occurs on the Sea-Aster {Aster tripolium), and, I think, 

 the Sea-Milkwort (Glaux maritima). Haliday suggested that its 

 food-plant was the Sea- Plantain (Plantago maritima).

A hothouse species, very distinct from the common H. hcemorr- 

 hoidalis, Bouche. Since taking this insect in one of Mr. Cookson's 

 orchid houses at Wylam-on-Tyne, Northumberland (VIII.07), I have 

 seen an example captured by Mr. C. O. Waterhouse at Acton (22. 

 Y1II.0G) and now in the British Museum. 



Distribution. Finland (Reuter) and North America (Pergande 

 and Hinds).*
