CERAMBYCIDjE. SAPERDA. 239 



ably narrower, slightly spinose at the apex, which is black, the base pale 

 griseous-ash. 



About six years since three examples of this fine species, which 

 feeds upon the poplar, were captured in the forest of Dean, Gloucs. 

 — but since that period numerous specimens have occurred in the 

 vicinity of " Cambridge." — C. C. Bahington, Esq. " Not very un- 

 common in the neighbourhood of Cambridge, occurring in August: 

 one specimen also taken at Swaffham Prior." — Rev. L. Jenyns. 



f Sp. 3. Tremulae. Nigra pube depressa ochraceo-vii^escente undique tecta, elytris 

 punctis duobus nigris. (Long. corp. 5 lin.) 



Sa. Tremulae. Fabriciusf—Steph. Catal. 198. A'b. 2034.— Sa.Atkinsoni. Curtis, 

 vi. pi. 275. 



" Black, completely/ clothed with short depressed ochraceous pubescence, with a 

 dull greenish cast : palpi piceous : tips of mandibles and eyes black : antenna? 

 subferruginous, except the three first joints : thorax punctured, with a central 

 channel at the base : elytra broadest, and square at the base, each shoulder 

 as if rubbed ; there are also two slight black dots at the middle near to the 

 suture, and two further apart, nearer to the apex." — Curtis, I. c. 



The true Sa. Tremulte has the thorax spotted, and four dots on each elytron. 



Of this insect I believe a single example only has hitherto 

 occurred in England ; of its locality I am not aware. 



Sp. 4. scalaris. Nigra subnitida, elytris lined suturali dentatS punctisque late- 

 ralibus Jlavo-pubescentibus. (Long. corp. 8—10 Un.) 



Ce. scalaris. Linne. — Donovan, xi. pi 393.— Sa. scalaris. Steph. Catal. 198. 

 No. 2030. 



Black, pilose, slightly shining ; beneath yellowish : head broad : thorax small, 

 deeply constricted towards the base, the lateral margin densely clothed with 

 flavescent pile, in which is a fuscescent spot, the disc glabrous : elytra with 

 the shoulders very prominent and rectangular, the apex shghtly narrowed 

 and rounded, the suture with a dentate Jlavescent line, and, five or six spots of 

 the same colour luithin the margin, some of them united to the sutural line : 

 antennae black, with the articulations at the base cinerascent. 



Found also upon the poplar ; very rare in the neighbourhood of 

 London, where, I believe, only the specimen mentioned by Do- 

 novan has been found : in the north of England, especially about 

 Cockermouth, it is not very rare, as I have seen numerous speci- 

 mens from this last locality. " Raehills, rare." — Uev. W. Little. 



Sp. 5. populnea. Nigra, villosa, profunde rugo^o punctata, thorace lineis, elytris 

 punctis plurimis Jluvescenti pubescent/bus. (Long. corp. 5 — 7 lin.)
