acute an observer as Dr. Prout should have overlooked the characters 

 of Prof. King's genus Synocladia. Our Scotch form and S. ces- 

 triensis, Prout, agree very closely, so far as I can judge from descrip- 

 tions and figures, and appear to differ only in a much greater irregu- 

 larity of branching in the case of S. carbonaria, and also in its having, 

 as in Synocladia, the cell- apertures arranged in two rows on the in- 

 terstices. Dr. Prout's figure does not give a good idea of this peculiar 

 polyzoon ; but I have been favoured by Prof. King with extracts and 

 photographs from a letter to himself from Mr. F. B. Meek, of Spring- 

 field, Illinois, regarding the question of Septopora and Synocladia. 

 These photographs show that the American specimens are in a much 

 better state of preservation than the Scotch ; and although the 

 points of difference between the two are slight, I think they are of 

 sufficient importance to warrant a specific separation ; however, 

 should Mr. Meek have previously elsewhere described any form 

 nearer S. carbonaria than Septopora cestriensis, my designation can 

 give place to his ; in the mean time I retain for the Scotch fossil 

 the name of S. carbonaria. Mr. Meek states that fuller descriptions 

 and figures will be given in the forthcoming fifth volume of the 

 ' Geological Survey of Illinois.'

[Continued from p. 156.] 



Fam. Cerambycidae. 



Section B. Eyes finely faceted. Habits diunial . 



Toxotus cceruleipe tints, n. sp. 



T. elongatus, subparallelus ( 3 ), niger, thoracis margine antico vit- 

 taque laterali, et annulo basaB femorum anticorum flavo-testaceis ; 

 elytris saturate caeruleis, planis, confertim ruguloso-punctatis, in- 

 terstitiisque subtilissime coriaceis, apice truncatis, angulo suturali 

 dentato, exteriore late rotundato. Long. 9 lin. 3 . 



Japan? {Fortune). Possibly from North China, as Mr. 

 Fortune's collections from the two countries were mixed to- 

 gether when I saw them. 



Elytra more elongate than in the same sex of T. meridianus, 

 and of quite different shape, being broad and rectangular at 

 the base, then slightly narrowing to beyond the middle, and 

 widening again before the apex ; the whole surface roughly, 

 but not very coarsely, sculptured. The thorax is much more 

 strongly tuberculated, glabrous on the disk ; there are two 

 strong rounded tubercles on each side the median sulcus, and
