tration of a series of the Cerambycidae, which has been given 

 in the " Guide ;" and by referring to the other plates it will 

 be seen that the natural situation of Callidium is between Sa- 

 perda and Clytus, Obrium following and connecting Mo- 

 lorchus. 



Mr. Kirby has given tlie history of one of the species in the 

 Linnean Transactions, where figures and dissections of the 

 larvae will also be found. 



The following species have been detected in Britain. 



1. C. striatum Linn. — Curtis Brit. JStit. j)l. 295. — agreste 

 Fah. — rusticum Steph. 



The black colour and greater number of elevated striae on 

 the elytra will distinguish this from C. rusticum. Two speci- 

 mens were taken at Kinnordy in Scotland, and one of them 

 was kindly presented to me by Mr. C. Lyell. It is not un- 

 common in Sweden. 



2. C. Bajulus Liti7i. — Panz. 70. 1. — similis Marsh, var. 

 Common round London on old posts and paling in June. 



Mr. Spence observes in the Introduction to Entomology, that 

 " The larva of C. Bajulus sometimes does material injury to 

 the wood-work of the roofs of houses in London, piercing in 

 every direction the fir rafters; and when arrived at the perfect 

 state, making its way out even through sheets of lead one-sixth 

 of an inch thick, when they happen to have been nailed upon 

 the rafter in which it has assumed its final metamorphosis." 



3. C. violaceum Linn. — Don. 2. 6^.f. 1. — Linn. Trans, v. 5. 

 tab. \2.—Panz. 70. 4*. 



I once found a single specimen in Norfolk ; and it has been 

 taken at Manchester in May; and occasionally in the neigh- 

 bourhood of London plentifully : it inhabits dead fir-trees. 



4. C. sanguineum Linn. — Don. 16. 553./. 1. — Panz. 70. 9. 

 It has been taken in Anglesea and Devon, and is sometimes 



found in oak-timber. 



5. C. variabile Linn. — fennicum Linn. — Panz. 70. 2. — tes- 

 taceum Liiin. var. — praeustum Fab. var. — luridum Paijli. var. 



For specimens of this insect I am indebted to a lady, who 

 finds them constantly feeding on the solid wood of the Birch. 

 It is said to have been found upon Oak in Hainault Forest, 

 Essex, in August; and a variety in trees at Battersea in June^ 



6. C. russicum Fab. — Oliv. v. 4. 'No. 70. pi. 4.y! 49. 



This is introduced on the authority of Mr. Stephens. Fa- 

 bricius states that the insect he described, from the cabinet of 

 Mr. Lee, came from Russia. 



7. C. Alni Linn. — Panz. 70. 20. 



Found in June upon faggots and hurdles in Woods, Nor- 

 folk, &c. 



8. C. luteum Steph. 



The plant is Stellaria graminca (Less Stitchwort).
