I RECEIVED a pair of this pretty and remarkable insect, which 

 has never been figured or described by any English writer, 

 with the following observations from Mr. Ingpen ; and I am 

 indebted to Mr. Ingall for a series of specimens for my cabinet 

 and dissection. 



" Mr. T. Ingall having discovered the habitat of this very 

 rare insect about the middle of April 1830, near Sydenham, 

 Kent, most liberally showed me its locality. In the first week 

 of May we found it inhabiting the bark of old elm-rails, in 

 which it makes labyrinth-like passages with outlet holes. The 

 insect seemed attached to the hardest bark, and to that which 

 was the most difficult to separate from the wood. It is remark- 

 able that they almost entirely confine themselves to the under- 

 side of the rails ; and the upright elm-posts, although the bark 

 was very much eaten, produced scarcely a specimen." 



Mr. Davis informs me that Dr. Howitt found a specimen, 

 near Nottingham I think, which was beaten from off a haw- 

 thorn hedge, and another is said to have been taken at Darent 

 in June. In Sweden it is found also under the bark of dead 

 trees, especially of the Finns sylvestris (the Scotch Fir). 



Nemosoma is placed by Latreille between Cis and Cerylon, 

 and there can be no doubt that it belongs to the Bostricidae ; 

 but never having had an opportunity of examining this rare 

 insect until now, I have arranged it in my Guide between 

 Bitoma and Rhyzophagus ; but its natural situation will be 

 near to Cis and Apate (Genera 328 and 330 of the Guide). 



The plant is Rubia peregrina (Wild Madder).
