and iu the second 6 specimens were of this blue form. More evidence 

 is required, however, fi'om the coast, where A. aenea is common where- 

 ever there are sandhills, as to the proportion existincr there between 

 the type and varietal forms. 



Among the Sternoxl and Lrmgicornia/the influence of afforesta- 

 tion with Scots pines is quite obvious. Such species as Lvmonius 

 aeruginostis 01. (ct/Undrictis Piijk.) ,a.nd Detiticollis {Campylus) linearis, 

 the former of which is extraordinarily abundant in the spring, probably 

 belong to the pre-pine period ; but Melanotus rnfipes, another very 

 common species, no doubt was made so by their advent, and among 

 the Longicornia, Asemmn striatum, now fairly frequent, and Crince- 

 j)hah(s ferns, of which at least one record exists, certainly arrived with 

 the pines. Indeed, our list of Longicornia, except such as may be 

 associated with these ti'ees, is an exceedingly small one. 



The district has so far afforded but little of interest among the 

 Phytophaga. Cryi)tocephalus bipiunctatns v. satiguinolentus Scop., is 

 always fairly common by sweeping, and a nearly black form of G. 

 pusiUus (v. marsJiami ?) is locally abundant on birches. Longitarsus 

 castaneus Foudr. (brunneus Duft.), which may always be known by its 

 white apical cilia, occurs in marshy places, and the beautiful but 

 unstable Cassida nohilis is frequent everywhere. Mr. Tomlin also 

 reports the captui*e of the much rarer C. sanquinolenta, all of which 

 were probably here before the pine woods existed. 



But among the Bhynchophora. there are several species that 

 directly depend on the pines. Thus Hylohius abietis is so abundant 

 that (I quote from a Government Report), "To combat this insect, 

 newly felled areas are now allowed to remain unplanted for four years 

 in order that the stumps, in which (when fresh) the beetles breed, 

 may lose their attractiveness." 



Of course all the Scolytidae associated with conifers are usually 

 very abundant, and one of the rarer species, Hylastes cunicularius, is 

 occasionally to be extracted from the stumps. Otherwise such species 

 of weevils as have been noticed are merely such as might occur on any 

 uncultivated land. Of the less common species, the broom which is 

 generally distributed gives us regularly, but not in abundance, Apion 

 fuscirostre, and A. immune ; and Ty chins venustns erratically. This 

 year (1915), Sitona griseus. has been locally in profusion on the same 

 plant, thus confii-ming the Rev. W. W. Fowler's suggestion (Col. 

 Brit. Isls., Vol. V, p. 219) that Genista might be its food-plant, a
