ADDITIONS TO THE LIST OF CLYDE COLEOPTERA i6i 



viii., 49) ; Clyde Islands, sweeping at Machrie Bay, Arran. This 

 species is considered rare in Britain. My specimens were taken 

 during July and August. 



M. fiiscus, Waltl. {pelhicidiis, Kies.). — Lanark, by sweeping 

 near Lanark in July. 



M. atomiis, Th. — Lanark, local, by sweeping near Lanark in 

 July. Females only were taken. The males are very rare. 



LONGICORNIA. 



Lepttira cerambyciformis, Schr. — Very local, Lanark, on blossom 

 of Meadow Sweet {Spircea) and umbelliferous flowers near Lanark, 

 July and August. 



Grammoptera riificornis, F. — Lanark, local with the preceding 

 species, near Lanark, July and August, Although not included in 

 the original Clyde list, this species is not strictly new to the area. 

 It appears to have occurred at Kenmuir Wood in the palmy days of 

 that locality (Cameron, Transactions of the Glasgow Society of Field 

 Natu7'alists, 1871-78, p. 7), but as it is no longer to be taken there 

 it is satisfactory that another station has been found for it. 



Phytophaga. 



Donacia obscura, Gyll. — Stirling, rare one by sweeping in a 

 marshy spot, Rowardennan, during June 19 14, and another in the 

 same place, June 191 9. 



Chrysomela brtinsvicensis, Grav. {didyjtiata, Brit. Cat.). — Clyde 

 Islands, in numbers upon Hypericum at Whiting Bay, Arran, 

 September 191 6 (Fergusson, Scot. PVat., 19 19, 167). 



Phytodecta pallida^ L. — Main Argyll, rare, Lochgoilhead, two 

 specimens under a stone upon the summit of Ben Donich (2774 

 feet). As both examples were quite immature, it was obvious that 

 the insect, in its larval stage, had been feeding about the summit 

 and had pupated under the stone where the beetles were found. 

 I came to the conclusion that the only plant upon which the larv^ 

 could have subsisted in that barren spot was a dwarf willow which 

 was not uncommon about the summit. 



Phyllodecta viilgatissima, L. — Main Argyll, on willows, 

 Lochgoilhead. This species has probably been overlooked in 

 other parts of the area. 



Psylliodes chrysocephala, L., v. anglica, F. — Clyde Islands, two 

 specimens of this variety with testaceous elytra occurred at Machrie 

 Bay, Arran, during September 191 3. 



P. napi, Koch. — Lanark, near Lanark by sweeping, September;
