Pompilus clialyheaius, ^ , and Wesmaeli, (^ $ , on the sandhills. 

 The latter species, with the curious spine in the middle of the venti'al 

 A'alve of the apical segment of the abdomen of the ^ , has only occurred 

 in this country before at Chobham. 



Miscophus marltimus, 2 (^ and several $ on the sandhills. 



Tachytes lativalvis, Thorns.?, ^ . I have taken 3 (^ of a Tacliytes 

 with the pubescence of the face bright golden. This peculiarity 

 Thomson gives as a characteristic of his lativalvis, but I only got the 

 one sex, and do not yet feel quite certain that it may not prove to 

 be a variety of pectinipes. 



Prosojns dilatata, both sexes common on Achillea millefolium. 



Colletes marginata, a few ^ , by sweeping, and several ? off the 

 flowers of Trifolium arvense, repens, and aqrariiim, on the sandhills, but 

 difiicult to see, as it frequents such very low growing plants. 



Cop.lioxys acuminata, 4 $ from a small sandy pit near Kingsdown. 



HEMIPTERA. 



In this Ox'der I did not capture many rarities, as my time was 

 almost exclusively devoted to the Symenoptera; Mr. E. P. Collett spent 

 one day with me, and worked more particularly for them, and, from 

 the result of his day's work, I should think that this year was not 

 below the average for the Heteroptera. Amongst my better captures 

 were : 



Odontoscelis fuliginosus, on the sandhills. 



Calyptonotus lynceus, on. the sandhills, but chiefly in the larval 

 form. I only got 2 perfect and Mr. Collett 1. 



Teratocoris Saundersi, in the same locality where I took it in 

 1868, and apparently confined, as then, to one spot, i. e., the small 

 rushy tract just when first one enters the open ground beyond Sandown 

 Castle, which is strewn with large stones. I took ^ and $ , only 2 of 

 the latter fully developed. 



Miridius quadrivirgatus, 2 specimens by sweeping. 



Plagiognathus Bohemani, and nigritulus, the former commonly, 

 the latter rarely, on the dwarf sallows, by sweeping and by grubbing 

 at their roots. 



Globiceps salicicola, Rent. ? (Ent. Mo. Mag., xvii, p. ItS), rarely, on 

 the dwarf sallows, by searching among the stems and at the roots. I 

 could not get it by sweeping. I must express my great doubt as to the 

 distinctness of this species ivom Jlavomaculatus. Renter lays stress on 

 the shape of the basal spot of the corium, but in the specimens I have 

 (8 males and 12 females), the shape of this spot varies in both sexes 

 from a basal triangle to a lateral vitta, extending to the apex of the
