Cheshire" to the (thirty-second) Annual Eeport and Proceedings of 

 the Lancashire and Cheshire Entomological Society for 1908. 



British Odonata. — In the ' Journal of the E.H.S. Garden Club,' 

 No. II., 1909, there is an annotated list of dragonflies found in the 

 county of Surrey, contributed by Mr. W. J. Lucas. 



The Oribatoidea of Illinois. — In an article bearing this title 

 Mr. Henry E. Ewing discusses the classification of the Oribatoidea, 

 describes thirty-three species (twelve new) from Illinois, and gives a 

 list of all the species known to occur in North America. This article 

 was published in the ' Bulletin ' of the Illinois State Laboratory of 

 Natural History, vol. vii. pp. 337-389, plates xxxiii.-xxxv. (September, 

 1909). 



Fossil Insects. — Prof. T. D. A. Cockerell (Bull. Amer. Mus. Nat. 

 Hist. xxvi. pp. 67-76) describes several new species of Diptera from 

 the Florissant Shales ; also a new species of Baphidia (Neuroptera), 

 and one of Orthoptera. Photos of five of the new" flies are shown on 

 plate xvi. 



The same author contributes " A Catalogue of the Generic Names 

 based on American Insects and Arachnids from the Tertiary Eocks, 

 with indications of the Type species " {I.e. pp. 77-86). 



Leucania pavicolor on Hackney Marshes. — Among the L. 

 ^aliens in the second portion of Mr. J. A. Clark's collection dispersed 

 at Stevens's last week was a specimen of L. favicolor, which evidently 

 escaped the notice of most buyers. This specimen is most interest- 

 ing as it is labelled " Hackney Marshes 2 vii. 05." Now one looks 

 on L. favicolor as a coast species, and one would not expect to find it 

 at Hackney. Of course we know that these marshes in olden times 

 were tidal, and the fact that Hama {JSIamcstra) ahjecta sometimes 

 occurs there makes one wonder if the old salt marsh insects have 

 hung on there in spite of these marshes being no longer of the old 

 character. I am not overlooking the fact that it is not so very far 

 across to the Thames, and that these insects could fly across if they 

 came up the river. — H. M. Edelsten ; Forty Hill, Enfield, Decem-

The Clark Collection. — On December 7th and 8th a further 

 portion of the collection of British Lepidoptera, formed by the late 

 Mr. J. A. Clark, was disposed of at Stevens's Auction Eooms. It 

 consisted chiefly of the more recent acquisitions of its late owner, 

 and although perhaps hardly so rich in extreme forms as the older 

 portion, it nevertheless contained a large number of really good 

 varieties and a larger proportion of the specimens were labelled with 

 more or less complete data. The chief interest appeared to centre 

 round some of the more remarkable forms, and, as on the former 

 occasion, some of the Continental collectors were desirous of obtain- 

 ing a share of them, but whereas then practically the whole of them 

 were secured for one or another of our British collections, some few 

 out of this later portion appear to have been more highly appreciated 

 by our neighbours, and thus to have found their way across the 

 Channel. The first lot to raise any great amount of enthusiasm was
