the genus Criocephalus. 153 



Spain, Bronchales, Tragaeete, La Granja (Champion) ; 

 Corsica, Vizzavona (Champion) ; Akbes (Coll. Oberthlir) ; 

 Amurland ; Japan (Lewis) ; Tsekou in North Yunnan (Coll. 

 Oberthlir) ; and I have seen specimens from Madeira and 

 other localities. 



The species has recently been discovered by Colonel 

 Yerbury at Nethy Bridge, near our wildest Highlands, 

 where the Scotch fir is still extant in its natural state. 

 The specimen he found was on a sprig of heather near a 

 large stump of the Scotch fir. It is a fine female and is 

 now in the collection at the British Museum. 



This specimen is I think undoubtedly a native of 

 Britain, and it is of importance as showing that the dis- 

 covery for the first time of a Griocephahis in a locality is 

 not sufficient evidence of its being an introduction. Mr. 

 Gilbert Smith's extremely interesting notes on the natural 

 history of C. ferns and Asemum striatum should also be 

 considered in this connection. There can however be 

 little doubt that this species is liable to be carried about ; 

 though probably this only occurs as an exception, even 

 when large blocks of timber are transmitted. A specimen 

 has been found in a coal-mine in Wales, where it was 

 pretty certainly carried in the wooden props ; and if 

 foreign fir-wood be used for railway sleepers it may thus 

 be transmitted. The case recorded of its introduction by 

 means of timber for masts must also be noticed. 



G. rnsticus was not known to Wollaston when he wrote 

 the " Insecta Maderensia " (published in 1854), but it after- 

 wards became common in the plantations of introduced 

 fir-trees, and in 1857 was recorded by him in the category 

 of " undoubtedly introduced " species. [The " G. rnsticus" 

 of the Canary Islands is G. pinetorum.] It appears to 

 have spread with rapidity in the Madeiran group, as in 

 1865 Wollaston recorded it from the extreme summit of 

 the small island called Dezerta Grande. But this must 

 be received with some caution, as it is far from impossible 

 that G. pinetoruvi occurs in Madeira as well as in the 

 Canaries.
