NOTES ON NEW AND RARE LOCAL BEETLES. 415 



of this short note. I cannot do better than quote Mr. Donis- 

 thorpe's translation of Ganglbauer's description : — ■ 



^' Agathidimn badin»i, Er. — -Very Vike se/iiinidum, on the whole of a 

 lighter red brown, the ground work of head and thorax shining, smooth, 

 also under very strong magnification with a hardly perceptible network, 

 the elytra with much weaker sutural striae, very slight or extinct towards 

 the middle, often only noticeable more or less towards the apex, the 

 metasternum with less strong lateral Hnes, the hind femora of the $ with a 

 very sharp-edged apical corner, forming a broad three-cornered tooth. 

 The third joint of the antenna about half as long again as the second, as 

 long or a little shorter than the following joints taken together. 



Long, 2 mm. -2-5 mm., North and Middle Europe, common." 



TviO very marked characters not mentioned in Ganglbauer's 

 description are noticeable upon comparing badium with senii- 

 milum. Owing to the earlier antennal joints being more 

 slender than those of stminulum, the club is much more con- 

 spicuous, and the antenna of the latter species is always 

 unicolorous, whereas in badium the club is pitchy. 



Dr. Chaster (Ent. Record, 1904, p. 18) also points out that 

 the posterior femora of badium are longer, so that their apices 

 project beyond the margins of the elytra and exhibit the 

 characteristic tooth. 



My examples occurred from beneath beech bark exclusively* 

 — apparently throughout the year, and in the summer I have 

 found it in a tree-growing fungus (one of the Hymenomycetes). 

 Though a common European species, it is evidently extremely 

 local in Britain, and confined to the North ; and, as seminulum 

 has not been taken in the North, I cannot think badiiim will 

 be found confused with that species in British collections. 



* Since this note was written the author (Jan. 1st, 1906) has discovered, feeding 

 beneath beech bark, a Silphid larva v/'hioh he believes to be the larva of A. badium.
