An account of this beetle is givdh by Mr. Sidebotham in the 

 Entomologist's Monthly Magazine, vol. viii. p. 180 ; he says that 

 iu September, 1871, he found the larvie of the species in small dry 

 specimens of Boritta plumbta and other small fungi on a sandy Hat near 

 Barmouth ; in less than a week, several perfect specimens of the insect 

 made their appearance ; sometimes the larva appears to eat its way out 

 of the fungus, and at once changes into the pupa state, from which it 

 turns into the perfect insect in about ten days ; but usually it forms a 

 cocoon of spores, changing to the pupa state inside the lungus, out of 

 which the perfect insect eats its way ; the species appears to be extremely 

 local. 



DORCATO1VXA, Thomson. 



The species belonging to this genus may be distinguished from their 

 allies by their more elongate form and less convex disc ; the eyes are 

 entire, and the antennae 10-jointed, rarely 9-jointed ; they are about 

 twenty in number, and are widely distributed, occurring in Europe, 

 South Africa, and North and South America; eight are found in 

 Europe, of which two are inhabitants of Britain ; they are both found 

 very rarely in decayed trees. 



I. Form narrower ; punctuation of elytra less close ; 



abdomen with all the segments free D. CHBTSOMBLINAJ Sturm. 



II. Form broader; punctuation of elytra closer; abdo- 

 men with the first segments sol lered together in the 



middle D. PLAVICOBNIS, F. 



D. chrysomelina, Sturm (Jresdensis, F., nee Herbst.). Oblong- 

 oval, clothed with uneven slightly erect greyish pubescence, shining 

 black, with the antennas, palpi, and legs testaceous, the latter being 

 sometimes partially infuscate ; head rather large ; antennas with the 

 first joint large, the second somewhat elongate, but very much smaller, 

 the following five very small, and the last three very much enlarged, 

 forming a loose club ; thorax transverse, gradually and rather strongly 

 narrowed in front, bisinuate at base ; scutellum small ; elytra with sides 

 subparallel to posterior third and thence narrowed to apex, not very 

 closely punctured, with two strias and a row of punctures on each at 

 sides ; under-side very finely and thickly punctured, with larger round 

 fl.it punctures interspersed; legs moderately long, tarsi short. L.
