Capture of some of the rarer species of Dclphaw near Newcastle. — 



Delphax hajaaiusx Bob. One male and tliroe females, brachypterons, taken by 

 sweeping rough herbage near Newcastle, in August. 



Delphax guthda:, Germar. I have one specimen from Gibside, taken in August ; 

 and several others, ^ and ? , found at the roots of grass on the sand-hills, near 

 Hartley, on the 6th of November last. All have the hemelytra fully developed. 



Delphax alboma^rqinatiis^ Curtis. I took a good many specimens of this rarity 

 by sweejiing grassy places in Briar-dene, near Whitley, in May and Juno. I got 

 both males and females, but all were of the brachypterous form. 



Delphax dis color ^JB oh. This rare species would appear to be widely si^road. 

 I have specimens of it taken on the sea-banks at Whitley, in Gosforth Woods, and 

 near Naworth, in Cumberland. All, both S and ? > are of the brachypterous form, 

 and were taken in May and Juno. 



Delphax striateUus, Fall. Apparently not rare. I have fully-developed males 

 and females from Briar-dene, Gosforth, and Gibside, taken in May, June, and 

 August. 



Delphax ;geUiicidus, Fab. The most abundant species of the genus with us. 

 On the 28th of August last, I found it in immense numbers on the rushes, near the 

 margin of the lake, at Gosforth. A ten minutes' sweep produced hundreds, but all 

 were of the brachypterous form, and varying considerably in colour. — Thos. Jno. 

 Bold, Long Benton, Newcastle-on-Tyne, December 4!ih, 1865. 



Homopterous and other insects taken in December. — When down on the sea- 

 coast, opposite St. Mary's Island, yesterday, I had a look for insects, and was much 

 surprised at the numbers astir. Parting the grass on the sandy slopes, I found, of 

 Homoptera, Delphax guttula (vaacropterons and larva), Acocephalus rivularis (?), 

 A. agre^tis (females and young larvas), AgaJlia venosa ( ? ), and Eupteryx citrinellus; 

 the last quite plentifully. Remiptera were of two species only, Stygnocoris arena- 

 rius and Salda saltatoria. The half-hour's search showed many of the Coleoptera 

 which frequent such places, such as various sjDecies of Dromius, Notiophilus, 

 Amara, Stemis, and Apion ; with swarms of Sitones lineatus and other commoners.

Note on monstrosity in the antemnB of a hug. — I find a pretty bug, Scolopostelpus 

 affimis, very common upon heath, and which seems subject to considerable variation 

 in the antenna). In the variety most commonly found, a joint is wanting on one 

 side only ; in which case the second or third joint, or both, are so much elongated 

 that the three will be nearly as long as the four joints of the other antenna. This 

 may not be at all singular, but 1 do not recollect seeing other Hemipteroua insects 

 so foiTtned. — Id. 



Re-capture of Heterocordylus unicolor, — I have again taken this local bug. On 

 visiting the locality. Briar-dene, near Whitley, on the 26th of June last, I found its 

 pabulum, the dyer's weed, just coming into flower. On it were many larva) and 

 pupas, but very few of tho perfect insect, and these only recently developed. 

 Visiting the place on the I7th of July, I found the imago in plenty, and tho other 

 stages had disappeared. Returning on the 2-lth of tho same month, not a traoe of 

 tho insect could be fouud. — Id.
