Body rather narrow of equal breadth; head sparsely and finely punc- 

 tated; antennae rather robust, their second and third joints about of 

 same length, the middle and neitdast ones nearly twice as broad as lon^. 

 Pronotum is posteriorly a little narrower than elytra, 1^ times as broad 

 as lonj, distinctly narrowing anteriorly, rather finely and not densely 

 punctated. Elytra as long as pronotum, rather robustly and dnesely punc- 

 tated, their posterior margin inside the outer corners slightly incurved;; 

 abdomen almost of even breadth, strongly glistening, the transversal grooves 

 with rather robust and dense punctation, the dorsal joints elsewhere with 

 fine and scattered punctation. Mesosternum finely carinated. L. 4-4.5 mm. 



Distributed everywhere in North and Middle Europe, and in the autumn 



often in great numbers in stem-mushrooms, namely in the eatable Boletus 



sodalis ; in this country mainly in woodland regions, but rather local. 



Specimens with darkly brown elytra are easily separated from the similar 



moesta by more finely punctated pronotum and the denser punctation of 



the transversal grooves of abdomen.

(Kraatz Ins. D. II, 102; Muls. et Rey Erevlp. 1874, 118; 'Janglb. Kaf. 

 M. II, 39. - lata Thorns. Skand. Col. II, 851). 



Very closely allied tc moorens . The color is alike in both; but myceto - 

 phaga is (accd.to Kraatz) somewhat larger and broader, anteriorly and pos- 

 teriorly more tapering. Antennae more robust, the next-last joints twice 

 as broad as long. Pronotum and elytra somewhat finer punctated, while the 

 punctation of the first three-four free dorsal joints of abdomen outside 

 the transversal grooves is distinctly denser and smoother, rather robust 

 and denpe. Mesosternum is carinated. L. 4-5 mm.
