76 COLEOPTERA. 



I have met. with it at Darenth, Croydon, Gravesend, Chat- 

 ham, Reigate and Dorking. 



84. Scolytus rugulosus, Ratzeb. ; E. W. Janson, Proc. 

 Ent. Soc. 6 July, 1857. 

 Eccoptogaster rugulosus (Koch), Ratzeb. Forst. Ins. i. 

 187, Tab. x.f. 10(1837). 



Found by Mr. Groves, in the dead branches of a pear- 

 tree, in his garden at Lewisham, who kindly gave me several 

 of the infested twigs, from which I reared a beautiful and 

 variable series. 



This species may be at once distinguished from its near 

 ally, S. intricatus, Ratzeb., by its smaller size, deeper, 

 coarser and rugulose sculpture, and by the punctures on the 

 interstices of the elytra, arranged in regular rows, being of 

 equal depth and size with those of the true or normal striae, 

 and by the apex of the elytra being usually more or less 

 broadly red. 



I may remark, that there is in Mr. Wollaston's collection, 

 an individual of this species, having the red blotch invading 

 nearly two-thirds of the elytra, and which I had not pre- 

 viously been able satisfactorily to determine, taken by that 

 gentleman several years back at St. Neots. 



Ratzeburg appears first to have described this insect under 

 the name which I have adopted, and which had been pre- 

 viously applied to it by Koch, in his collection and in litteris. 

 Ratzeburg gives as synonyms S. punctatusj 3Ius. Berol., 

 and S. hcemorrhous, Ulrich. 



In Vincent Kollar's " Treatise on Insects injurious to Gar- 

 deners, Foresters and Farmers," of which an English trans- 

 lation was published in 1840, by the Misses Loudon, with 

 notes by Mr. Westwood, will be found some interesting ob- 

 servations by Canon Schmidberger on the natural history of 

 the present species, specimens of which, he informs us, had
