86 ' September, 



one expected to find in abundance. I may take the following as 

 examples of divergence in the experiences of Mr. Smith in July and 

 August, 1857, and myself in July and August, 1882. 



HYMENOPTERA. 



Andrena Ilattorfiana. Smith says : " The fine red variety, and 

 also the black, in about equal numbers ; in all, thirty fine specimens 

 of the female, the male we were too late for. All were taken on the 

 flowers of Scabiosa arvensis.'' This year the black variety of the $ 

 was common, but I could not get a single coloured one ; I got the c? 

 also, but not so commonly, and only when first I arrived, about the 

 20th of July : at that time both sexes frequented the flowers of 

 Centnurea scahiosa, but, later on, when Scabiosa arvensis n'as in full 

 bloom, although the Centaurea was still out, they appeared to visit S. 

 arvensis almost exclusively. 



A?idrena Cetii. — " This pretty little species was plentiful on the 

 scabious ; we found every variety, including the ' ajfinis,' of Kirby — 

 the male varieties include the A. frontalis of Smith" (Smith). Of 

 this insect I could not find a single specimen. The weather was fine, 

 the scabious abundant, and the time of year and locality the same as 

 when Smith was collecting, but no Cetii could I find. 



Andrena simillima. — " Extremely abundant on the flowers of the 

 blackberry ; this species was taken at the foot of the cliffs, half a 

 mile beyond Kingsdown " (Smith). This species also I could not find, 

 but I expect I did not go far enough along the coast for it. 



Andrena coifana. — " Very plentiful " (Smith). I did not meet 

 with it. 



JVomada J acobccce " in some numbers" (Smith). I did not meet 

 with it. 



EpeoJus variegatus. — " Taken plentifully " (Smith). I found it, 

 but very rarely. 



Cilissa leiiorina "on the slope of Kingsdown it abounded" 

 (Smith). I only found one worn (J. 



If there were any doubt as to the locality or the time of year the 

 absence of these species might be explained, but Mr. Smith, in his 

 article in the Annual, says : " During the latter part of July and the 

 beginning of August," and describes the locality at Kingsdown so 

 exactly, that it could not be mistaken ; the only difference in the 

 place seems to be that in 1857 the ground above the slope at the side 

 of the road between "Walmcr and Kingsdown was waste, and now it is 

 cultivated, but the slope itself remains in its natural state. I also 

 took the following, which I think are worthy of notice : —
