eapite dilutiore cum thorace hand mneo-micaniibus, elytrorum Jmmeris comparatim 

 sat promihulis, punctis plerumque {ao prmcipue basin versus) seriatim dispositis, 

 angulo suturali minus ohtxiso, tibiarum posticarum calcari multo longiori, tarsisque 

 posticis longioribus, optime distinguenda. 



I have for some time had an example of this species, taken by myself at Mickle- 

 ham, undetermined in my collection, as allied to atricilla ; but it was not until 

 recently, on seeing several specimens of it (taken by Mr. Champion, according to 

 his recollection on Senecio jacohcta, at Box Hill, during September last), that I felt 

 convinced of its separate specific value. 



Of European species not recorded as British, it would seem in many characters 

 to approach T. crassicornis, Toudras ; but the entirely obsolete or absent thoracic 

 punctuation of that insect, and the fact of Allard stating the joints of its antennae 

 to be more slender and longer than in melanocephala, render further comparison 

 needless. 



It seems nearest to atricilla, Gyll., differing from that common species, as above 

 noted, in being of average rather larger size, without a dark brassy head and thorax, 

 of less regularly oval outline, the greatest width being nearer the apex, with more per- 

 ceptible shoulders to the elytra (of which the punctuation is rather stronger and in 

 most of the specimens evidently disposed in strite, especially towai'ds the base, and 

 the apical angle is not so rounded off, being scarcely more obtuse than in melano- 

 cephala), and with longer posterior tarsi, and a longer and stronger spur to the 

 posterior tibia?. The principal character, however, seems to be in the antennas, which, 

 for a Thgamis, are unusually stout, being in both sexes more so than in atricilla, and, 

 indeed, than in any other of the genus known to me. The basal joint is as long as 

 joints 2 and 3 together, and is considerably thickened and curved outwards towards 

 the apex, joints 2 and 3 are short, 3 being rather the longer, 4 and 5 are sub-equal, 

 each much longer than 3, and from thence to the apex the joints become gradually 

 rather shorter and wider. The punctuation of the thorax, though very shallow and 

 not clearly defined, is tolerably close, and in some examples almost confluent, the 

 surface thereby becoming apparently slightly roughened, but there is a great latitude 

 in this respect, as in others only traces of similar punctuation can be seen ; in like 

 manner the punctuation of the elytra is in some specimens more confused than in 

 others, the tendency to striiE becoming thereby less perceptible. — E. C. Bye, 10,

Note on a recent capture of Lyniexylon navale in Cheshire. — I have been so 

 fortunate as to capture five examples of the above species, hitherto somewhat doubt- 

 ful as British, during the past season, at rest on the root end of a felled oak which 

 was struck with lightning about four years ago, one side being destroyed. I found 

 them all within a radius of eight inches, at foiu* different times, — one on the 20th 

 and two on the 27tli of July, one on the 3rd and another in the latter end of August ; 

 this last specimen my friend, Mr. Sidebotham, had the pleasure of seeing alive. 



Mr. Sidebotham and I visited the tree about the middle of August, and foimd 

 what we believed to be the burrows of the Lymexylon, as we observed in them the 

 exuviae of beetle pupae. Mr. Sidebotham has since, by digging into the wood of the 

 tree, found a dead specimen, and also larvae that are no doubt those of Lymexylon. —
