Metandi-ya.'] HETEROMEBA. 41 



broader tlian any of the other segments ; the segments are incise! at the joints, but 

 are ve\v narrowly separated by membrane ; the seventh and eighth abdominal 

 segments are smooth on disc, and the last segment is very short, without cerci ; the 

 pupa resemMes in shape that of ConopaJpus, but has the " styli motorii" smaller and 

 not terminated by sets? ; the larva is found iu dead oaks, beeches, alders, &c., in 

 which it forms galleries. 



J. Thorax without central furrow; elytra with strisB reach- 

 ins from b;;se to apex M. CAEABOIDES, L. 



II. Thorax with distinct central furrow ; elytra smooth at 



base, but with deep striae behind M. nrsiA, Sr.hill. 



(c'inaliculata, F.) 



M. caraboides, L. Black, elytra often with a bluish or greenish 

 reflection, shining, clothed -with short and fine black pubescence, palpi, 

 apex of anteunae, anterior tarsi entirely or at apex, and last two joints of 

 the other tarsi, reddish-yellow ; head rather finely punctured, antennae 

 comparatively short ; thorax a little broader than long, strongly narrowed 

 in front, broadest a little before base, moderately strongly punctured, 

 with a strong basal impression on each side; elytra depressed, a little 

 broader at base than thorax, often bluish or greenish, with somewhat 

 obsolete striae, interstices convex, punctuation very close, subrngose ; legs 

 long. L. 10-14 mm. 



In old willow stumps, &c. ; local, but rather common in some districts ; London 

 district, somewhat common, Norwood, Darenth Wood, L^e, Charltou, Duhvich, 

 Sevenoaks, Belvedere, Tonbridge ; The Holt, Farnbara ; Hastings; Dover; Holm 

 Bush, Brighton ; New Forest ; Portsea ; Glanvilles Wootton ; Swansea ; Llangollen ; 

 Knowle, near Birmingham ; Hepton ; Norbury, Cheshire ; Dunham Park and Agecroft, 

 near Manchester; Northumberland and Durham district; Ireland, Malahide near 

 Dublin. 



M. dubia, Schall. (canal iculata, F.). Smaller on the average than 

 the preceding, and more parallel-sided ; it may be known by the fact 

 that the thorax has a deep central furrow, and that each elytron has 

 four strong longitudinal striae or sulci Avhich are obliterated at base, the 

 interstices being convex and raised; colour black, with a bluish reflec- 

 tion, pubescence short, black, punctuation fine on head and thorax, fine 

 and subrugose on elytra ; anteunae and legs black, with the apex of the 

 former and more or less of the tarsi testaceous or brownish-red. L. 10- 

 12 mm. 



Under bark of decaying oaks, &c. ; one of the rarest of the British beetles ; I only 

 know of three specimens ; one of these was taken by Mr. Bentley, as recorded by 

 Curtis, flying near Brockeubnrst in the New Forest in 1823 ; one was m3t with by 

 Turner in the New Forest during the first season he collected, and is now in Mr. S. 

 Stevens' collection ; and the third was sent with some beetles to Mr. Harris of 

 Burton-on-Trent from the same locality, with a few common things, by Mr. Gulliver 

 of Brockenhurst, in the autumn of 1877 ; the specie.-, therefore, is evidently still to 

 be found in its old locality.
