to reeonl tlie more iiileresliitg s|5ccies taken, vvliich have not., so far as I know, been 

 already recorded. Anarete candidata, Hal., was taken on ragwort in the autumn, 

 Oxycera pardalina, Mg., very common in Murrock in August, dozens might 

 have been swept fi'oin marshy parts in the glen, one specimen, evidently 

 of O. dives, L\v., was also taken. IViedemannia rhynchops. Now., on rocks in 

 Murroch Grlen ; Tachydromia Ititea, Fin., common; Chrysotus amplicomis, Ztt., 

 common at Cardross ; Diaphorus nigricanx, Mg., common, Cardross and Bonhill ; 

 Acha/ciis JJavicolUs, Mg., Cardross and Eon hill ; llydrophorus praecox, Card- 

 ross ; Xanthuchlorus ornatus, Hal., Eonhill ; Ayathomyia antennata, Ztt., 1 ^,

 fulvivenfris, Mg , on ragwort iu August; Aoiiira rolandiventris, Fin., 1 specimen 

 only ; ISpilographa zoe, Mg., '-i ^ ^ ; Sapromyza alhiceps, Fin., 2 specimens (I 

 cannot understand this species being placed in this genus, as the frontal bristles 

 ought to remove it fi'om Sapromyza, possibly this is the reason for its appearing in 

 italics in Verrall's list) ;* JJiscocerina nigrina, Mg., common ; Hydrellia thorac'ica^ 

 Hal., common, Bonliill and Cardross ; Axysta ceda, Hal., 2 specimens ; Caenia pa- 

 liistris, Fin., not uncommon ; Napomyza lateralis, Fin., scarce ; N. elegans Mg., 1 <J 

 of this beautiful species at Cardross in July ; Limosina acutangula, Ztt., Cai'dross ; 

 L. zosferx, Hal., common, Bonhill, and Cardross on the shore ; L. pumilio, Mg., this 

 species is common everywhere on marsliy ground, and runs upon the surface of the 

 stagnant water. I have a very large number of specimens iu all the smaller groups 

 at the end of the list that are still unidentified, a large number of which are not in 

 our British list, and some of them are probably undeseribed. Where no locality is 

 given ibr species in the foregoing list, they were taken at Bonhill. — J. R. Malloch,

EssAxa ON Evolution, 18S9 — 1907 : by Edward Bagnall Poulton, 

 U.Sc, M.A., F.R.S., &c., &c., Hope Professor of Zoology at the University of 

 Oxford. Oxford : at the Clarendon Press. 19u8. 



This very important contribution to the literature of Evolution comprises 

 a series of ten addresses and lectures delivered by Professor Poulton at various 

 times and places between 1889 and 1905. All of them have, however, been care- 

 fully and thoroughly brought up to the standard of our present knowledge, and are 

 " the expression of a continuous line of tliought " ; although in nearly every case 

 they have been greatly extended and modified from their original form, and the 

 last, and perhaps the most important, " The Place of Mimicry in a Scheme of 

 Defensive Coloration," has been almost entirely re-wmtten. As may be expected 

 from the very high standing of the author as an interpreter of Insect Bionomics, 

 the majority of the illustrations of the Evolutionary Theory, as viewed by him 



* Species in italics in this " List " are those needing confirmation as belonging to our fauna. 

 A genus, Paralauxania, has been founded recently by Herr Hendsl for this species (Eds.).
