uniformity of the terminal joints in all the palpi. The Saperdas 

 are distinguished by their long and linear form, the shoulders 

 being very high, and the thorax, which is cylindrical, is never 

 spined. 



The following species have been discovered in Britain : — 



1. S. Carcharias Linn. — Panz. 69. 1. — similis Lat. — July, 



trees in Dean Forest, Gloucestershire ; and the Rev. 

 L. Jenyns informs me that specimens were taken on 

 a post near Cambridge, in August last. 



2. S. Atkinson! Nob. — Until I obtained authentic speci- 



mens of S. TremulcB from Germany, I considered this 

 insect to be a variety only of that species ; but as I 

 now believe it to be quite distinct and undescribed, I 

 have named it after my esteemed and lamented young- 

 friend the late Mr. John Atkinson of Grove-end, to 

 whom I was indebted for this valuable acquisition. 



3. S. scalaris Linn. — Don. 11. 393. — Panz. 49. 3. — This in- 



sect is not uncommon near Cockermouth ; the late 

 Mr. J. Atkinson of Leeds took one near Bolton, the 

 end of June, and Mr. Hobson has presented me with 

 a fine specimen taken in Kersal Moor Clough, near 

 Manchester. 



4. S. populnea Linn. — Panz. 69. 7. — Not uncommon upon 



Aspen trees in Coomb Wood, near London, and in 

 Sexton Wood, Suffolk, in May and June. 



5. S. Cardui Linn. — Panz. 69. 6. — lineato-coUis Don. 6. 209. 



— Taken in May, June, and July, by the Rev. 

 R. Sheppard, at Barton St. Mary, Norfolk, upon 

 Heracleum Sphondylium, and by Mr. Dale in Clap- 

 ham Park Wood, Bedfordshire. 



6. S. ferrea Schrank.—Pa7iz. 97. 15.— Mr. R. Wood of Man- 



chester took specimens the end of July 1828, at 

 Cattrel Clough, near Wilmslow; and I am indebted 

 to him for a fine pair of this insect, which is new to 

 Britain. I am informed by Mr. Davis that it has 

 since been captured by Dr. Howitt in Sherwood Fo- 

 rest, near Nottingham, upon Tilia 2Jctrvifolia; and 

 Dr. Stephenson has found another. 



7. S. cylindrica Litm. — Panz. 69. 4. — This I have taken 



early in May, upon Nettles in different parts of Nor- 

 folk. Rcesel says the larva feeds upon the pith of the 

 Raspberry.

June, upon trunks of willows, in the Isle of Ely, Cam- 

 bridgeshire.
