transverse, similarly punctured, the suture indicated by a carina, which is irregular, 

 owing to the punctures encroaching on its course ; the metasternum and the first 

 segment of the abdomen are punctured somewhat like the mesosternum, but many 

 of the punctui'es are larger ; the legs dull reddish-brown, anterior femora coarsely 

 punctured on the lower surface.

 Mr. Julius Flobr from " beneath decaying plants on the Sacromonte 

 at Amecameca, alt. 8300 feet."

NOTE ON ORTHOTYLUS OCMROTBICHUS, DOUG. AND SCOTT. 

 BY EDWAED SAUNDERS, E.L.S. 



I have recently had occasion to examine our British species of 

 OriJiotylus with green cell nerves, and was surprised to find that some 

 of those which I have taken near Woking are quite distinct from Scotti, 

 as described and figured by Eeuter (Hem. Gym. Eur., iii, p. 350, pi. 

 V, 17), and were apparently referable to his propmquus ; to make sure 

 of this I wrote to Professor E-euter, who very kindly sent me his type 

 specimens to examine, which quite confirmed the opinion I had formed 

 from his work. 



I was about to hviug prop i7iquus forward as a new British species, 

 when it occurred to me that before doing so I ought to examine the 

 type of oclirotrichus, D. & S., now in the British Museum. This, with 

 the assistance of Mr. C. O. Waterhouse, I have now done, and find 

 that propinquus and ochrotrichus are identical ; the latter name being 

 the older will take precedence, so that now we have four closely allied 

 species, viridinervis, Kb., ^r^smz^s. Fall, Scotti, Eeut., and ochrotri- 

 chus, D. & S., all, I believe, inhabiting elm trees, the last named was 

 originally described from a single ^ said to have been taken on Onoiiis^ 

 and which had peculiar small yellow spots on the elytra. 



I examined this specimen years ago, and feeling convinced that 

 these spots were merely due to some casual irregularity in the distri- 

 bution of the green pigment, T considered it merely as a variety of 

 Scotti ; on re-examination, however, it proves to have the peculiarly 

 formed genital forcipes of 'propinquus, the left hand one of these is 

 very convex outwardly at the base, rounded and denticulated along its 

 upper margin, and has its lower margin produced laterally into a lono-, 

 rather twisted, pointed process ; the right hand one is stipitate, trian- 

 gular, and truncate at the apex ; it may be also known by the distinct 

 carina along the vertex in both sexes. The specimens I have are all
