Kote on Orthott/lus Saiindersi, Eeui.,or TinicepJiaJus ohsoJetus, Fieh. — I -wish to 

 say a few words on this subject, cliiefly as an apology to Messrs. Douglas & Scott for 

 having so unhesitatingly removed the species that they had placed in the genus 

 Tinieephalus to that of Orthotylus, on account of the absence of the hanuis in the 

 wing-cells of the specimens under my examination ; whereas, it now appears, that 

 there are really two distinct forms, one with and the other without this character. 

 I had been examining two males without the hamus ; Messrs. Douglas & Scott, and 

 Dr. Fieber, who originally described Tinieephalus obsoletvs, had before them speci- 

 mens with it ; and therefore, although the observations I made on my specimens were 

 so far correct, yet I was, of course, not justified in so rapidly jumping to a conclusion 

 that I was right and that they must be wrong, and I am glad to be able to say so 

 here. 



Now, the question remains, are there, as Dr. Keuter suggests (p. 120 ante), two 

 species almost exactly alike in separate genera, or only one, and, if one, is it an 

 Orthotyhis, a Tinieephalus, or a Macrocoleus ? Should the hamus prove to be not 

 an essential character, there would be, so far as I know, great diiBculty in distin- 

 guishing between these three genera as now constituted. For myself, I cannot but 

 feel convinced that we are regarding two forms of the same species ; but the absence 

 of the hamus occasionally in a single species, may not be sufficient to upset a dis- 

 tinction which separates two apparently natural groups. If we still regard the 

 hamus as generically distinctive, ohsoletus will have to be a Tinieephalus or a 

 Maci'ocoleus, and its name will at any rate be suggestive of the occasionally obsolete 

 hamus. I cannot think that it can be a hybrid with any of the other green species, 

 as, if so, I think one would find the specimens more inclining to green in colour, or 

 at any rate, partaking of some other of the characters of Orthotylus than the negative 

 one of the absence of the hamus. — Edwabd Saunders, Holmesdale, Upper Tooting :

Captures of Ilemiptera-Heteropfera in Morayshire. — During the past summer 

 I have been collecting Hemiptera in the neighbourhood of Forres, in Morayshire, 

 and send for publication a list of my captures. From the northern position of 

 Forres the list will be interesting to those who pay attention to the geographical 

 range of species. With few exceptions my captures have been seen by Mr. E. 

 Saunders, who kindly undertook to name them for me. The species not otherwise 

 denoted are common. 



Piezodorus liturattis. 



Acanthosoma griseum and A. dentaium. 



Tropicoris rtifipes. 



Oastrodes ferruf/ineus. 



Nysiws thy mi (on thyme and by sweeping near the sea-shore). 



Eremocoris pleleius (local, under stones among heather under pine-trees). 



Scolopostethus affmis, and S. ericetorum (rare). 



Macrodema micropterum (occasional, among heather). 



Drymus sylvaticus (not common), U. hi-unneus. 



Peritrechus luniger. 



Stygnocoris sabulosus and S. arenarius. 



Isehnorrhynehtis didymiis (occasionally).
