Notes on Coccinellidae {nith one plate). 

 By G. B. C. LEMAN. 



1. In August last I took in the Putney district two aberrations of 

 Coccinella ll-pnnctata whicli are not included in Mr. H. St. J. K. 

 Donistborpe's interesting monograph on this species (see Ent. Record., 

 Vol. XXX., No. 7, pp. 121-128), and on his suggestion I venture to 

 name them as follows : — 



(rt) Ab. biiiisesgiii-punctata, n. ab. — -This conforms to the type with 

 the exception that the 2nd and 4th spots are wanting — one specimen 

 taken on thistle Putney Vale, S.W., Aug., 1919. (See Plate V., fig. 1). 



{b) Ab. tnniseaqni-pnnctata, n. ab. — This also conforms to the type 

 but the 3rd spot is wanting — two specimens taken on thistles at the 

 same place. (See Plate V., fig. 2). 



Incidentally I may mention that I took also a specimen with the 

 3rd spot wanting on the right elytron only, which suggests a stage in 

 the evolution of this new aberration. 



2. In the same month and district I also took with the type the 

 following recorded aberrations of C. ll-pnnctata, viz., ab. confliiens, 

 Haw. (present in considerable numbers), ab. cakiles, ab. 9-punctata 

 (both in fair numbers), and ab. ta)naricis (two) ; also a specimen with 

 spots 4 and 5 confluent on the right elytron only, and six specimens 

 with spots 2 and 3 confluent only, in each case on the right elytron, 

 again suggesting stages in the evolution of the respective aberrations 

 ab. tamaricis and ab. conflaens. The process of evolution appears to 

 commence with the right elytron. 



3. In the New Forest district near Eingwood, Hants, earlier in 

 August I swept up with type the following aberrations of C. ll-pitnctata, 

 viz., ab. confliiens, Haw. (sis specimens), ab. variegata (one) ab. cakiles 

 (one), and ab. 9-punctata (one), and at Winchester, ab. co)ifliie,m. Haw. 

 (four). I have subqaitted all my specimens to Mr. Donisthorpe, who 

 has kindly confirmed my identification of them and- has always most 

 generously given me every help" in identifying my Coccinellidae and 

 other specimens of Coleoptera. I think it may be of interest to mention 

 the finding of these aberrations as I do not think that so far ab. cakiles, 

 ab. taniaricis, and ab. variegata are recorded for the British Isles. 



4. I may add that in this district I have also taken a " freak " 

 specimen of C. ll-pnnctata with spots 1, 2, 3 and 4 again wanting on 

 the right elytron, which is the nearest approach to the ab. tripnnctata 

 I have so far succeeded in taking. 



6. I took another "freak" specimen on September 10th, on the 

 Ashtead Manor Estate, attributable to C. 7-pnnctata. This curious 

 specimen has the normal 3^ spots on the right elytron but the left 

 elytron is unicolorously black, but this is probably attributable to 

 some injury in the larval or pupal state, as this elytron is somewhat 

 deformed at the apex and margin. 



6. Last year I took on potatoe haulm (a favourite habitat here for 

 Adalia bipunctata) with type a specimen with the sutural basal spot 



DECEMBER, 1919.
