Allied to A. mycetopJiaga, Kr., especially by the structure of its 

 antennae, but not so brightly coloured, with the abdomen less narrowed 

 towards the apes and more sparingly punctured. The antennae have 

 the two or three basal joints obscurely yellowish, the others pitchy- 

 black ; the fourth joint is about as long as broad, the fifth to the tenth 

 transverse, each one a little broader than its predecessor, the eleventh 

 rather stout, pointed, about as long as the two preceding. The head is 

 small, black, shining, sparingly and finely punctured, and the palpi 

 are yellowish. The thorax is a little narrower than the elytra, its breadth 

 one and a half times its length ; it is rounded at the sides and narrowed 

 towards the front, tolerably distinctly but not closely punctured. The 

 elytra are about as long as the thorax, of an obscure red or brownish 

 colour, rather closely and distinctly punctured. The abdomen is black 

 and shining, obscurely reddish at the extremity, rather narrowed to- 

 wards the apex, segments 2 — 5 transversely impressed at the base, and 

 in the impressions closely and distinctly punctured, otherwise sparingly 

 punctured. The legs are reddish. 



Three specimens found in fungus at Eccles. 



Obs. — This species, as well as A. my cetophaga, is distinguished from 

 brunneipennis, Kr., and vicerens, Gyll., by its shorter and more clavate 

 antennae. 



OlYPODA LONGIPES, Muls., Op. 12, p. 103. 



This species closely resembles 0. vittata, from which, however, it 

 differs very decidedly in the much longer intermediate joints of its 

 posterior tarsi, and also in the larger terminal joint of its antennae. 

 The O. metatarsalis of Thomson (Sk. Col., ix, p. 246) must be very 

 closely allied to this species, if not identical with it. 



I have seen but a single specimen, which I captured at Aberlady, 

 near Edinburgh.
