In compiling the above list, I am happy to express my 

 obligations to my friend T. V. Wollaston, Esq. of Cambridge, 

 for his aid in ascertaining the obscurer species, and to Dr. 

 Johnston and Mr. Hislop for the communication of informa- 

 tion and specimens. To Mr. Hislop I am indebted for Nos. 

 6, 42, 60, 51, 52, 55, 58, 59, 75, 76, and 128, chiefly from 

 the west of Berwickshire. Nos. 14, 19, 20, 22, 54, 64, 96, 

 134, and several of the species of Thyamisj are from Dr. John- 

 ston's collection. In the last number of the Club's Pro- 

 ceedings, I remarked that my specimen of Calaihus picevs was 

 provided with wings. Mr. Hislop, who finds it in some abun- 

 dance about the roots and under the bark of decaying stumps 

 of trees near Mellerstain, informs me, that most of his speci- 

 mens are winged. Stephens mentions a similar circumstance 

 with respect to the Calathus crocopus from Yorkshire ; a spe- 

 cies usually described without wings. Erichson has also ob- 

 served on Calosamay " that one and the same species is some- 

 times winged, sometimes wingless.'' Alexia pilifera, for which 

 there is only one British locality, was found with Agathidium 

 atruniy under a decaying log of wood in Penmanshiel wood. 

 Bradytus marginattLs and Phalacms ulicis, also rare species, 

 were found on the moor above Drakemire. The latter insect, 

 together with Cercyon convexitisculum,{J) several of the Leiodes, 

 and Agathidium seminulumy were abroad very late in the even- 

 ing ; a circumstance that would indicate nocturnal predilec- 

 tions. . The Leiodes frequently lurk during the day under 

 stones and moss ; and are observed to make their appearance 

 in cloudy weather. Mr. Henderson informs me that CocineUa 

 7-punctata and C. Tartabilis have been in considerable abun- 

 dance, during the season, in the vicinity of Chirnside. I re- 

 marked, of the latter species, that it was very late this season 

 in showing itself ; scarcely a mature specimen being seen about 

 the middle of July. It frequents the spruce fir, from the Aphis 

 of which its larvae derives its principal sustenance ; though it 

 is not confined to this tree. The C. l-punctata was the spe-
