much more closely punctured thorax, and bj the quite different shape of the apical 

 segment. This in eeneus has simply a rounded margin, notched triangularly in the 

 middle. In truncatus the sides are widely scarious, and strongly sinuated inwards 

 before the apex, which projects considerably, and is also abruptly truncated, forming 

 a distinct " apical platform," or wide flattened border to the triangular excision. 



In this part of its structui-e truncatus recalls rather Notozus Panzeri, F., than 

 our other species of Ellampus ; and it was on this ground, I suppose, that Dahlbom 

 grouped it with Panzeri, &c., in his genus " Elampus," which we now call Notozus, 

 while he placed eeneus, &c., in Omalus (= Ellampus in the modern sense). How- 

 ever, as the genera are now defined (see du Buysson, in " Species," vol vi, pp. 95, 

 116), truncatus is an Ellampus, and not a Notozus. 



Mr. Perkins has been good enough to send me a list he has made 

 of the Chrjsids in the Walcott collection at Cambridge. This, besides 

 E. truncatus, contains all the species I have recorded as British in 

 this Magazine except Holopyga gloriosa, F., Sedychridium integrum, 

 Dhlb., and coriaceum, Dhlb., and Chrysis osmicB,T\xoxn^. The first and 

 the last of these, if indeed they are really British, have still to be re- 

 discovered. Of coriaceum I still know only of two British specimens, 

 both taken by myself. But integrum, I am glad to say, has of late 

 been found pretty freely by Mr. Perkins in a new locality, viz , Suffolk. 

 There seems some reason to suspect this species of parasitism on 

 Astatus stigma, Pz. At least these two rarities have occurred together 

 both to Mr. Perkins in Suffolk and to myself at one particular spot 

 near here, and 1 have also taken the two kinds in abundance near the 

 Simplon Pass in Switzerland. If this be so, I think it is likely that 

 H. roseuni, Eossi, is parasitic on our other Astatus (hoops, Schr.), in 

 whose neighbourhood I have several times captured it.

SOME OLD EECORDS OF THE OCCURRENCE OF CERTAIN 

 DRAGON-FLIES IN SCOTLAND. 



BY KENNETH J. MORTON, F.E.S. 



When in Dumfries a few weeks ago, Mr. Eobert Service called 

 ray attention to a small book, entitled ''Handbook of Colvend and 

 Southwick " (Dumfries : J. Maxwell and Son, 1895, a second edition, 

 the preface to the first being dated 1873). It is mainly of local 

 interest, but a certain value has been attached to it from an entomo- 

 logical point of view by several lists of insects contributed by the 

 late Dr. Buchanan White. 



I understand Dr. White spent two different seasons at Colvend,
