The following corrections to the " Preliminary " and "Sup- 

 plementary" Lists may be conveniently made here. 



Harpalus picipennis, Dufts. Although named as this species by 



Capt. St. Claire Deville, the insect in question differs from it in many 



respects, and Mr. W. Holland and I can only regard it as a very 



small and abnormal 9 example of H. rufimanus, Marsh. The 



specimen is now in the Oxford University Museum. 

 Haliplus confinis, Steph. This should be //. obliquus, Fab. 

 Laccobius minutus, L. Recorded in error for L. alutaceus, Thorns. 

 Helophorus mulsanti, Rye. A rather brightly-coloured form of //. 



(Encipennis, Thorns., found in standing water at Tubney, lias been 



confused with this littoral species. 

 Anisotoma parvula, Sahib. The Oxford specimens hitherto regarded 



as this species must be referred to A. flavicornis, Bris. (Cf. Joy, 



Ent. Mo. Mag., 1908, p. 174). 

 Euplectus signatus, Reich. This should be E. sanguineus, Denny. 

 Scymnus ater, Kug. Recorded in error. 

 Cerylon ferrugineum, Steph. The insect, on the strength of which 



this species was inserted in the " Preliminary List," is a ferruginous 



form of C. histeroides, Fr. 

 Atomaria basalis, Er. Only a brightly-marked specimen of A. analis, 



Er. 

 Scolytus rugulosus. Ratz. Recorded in error for S. intricatus, Ratz.
