Testaceous; head pitchy-black, with scattered punctures; 

 thorax fuscous or fusco-testaceous, with two discoidal rows of 

 punctures ; elytra pale testaceous, with the outer margin (except- 

 ing near and at the shoulder) black ; the black dilated near the 

 hinder angle, with minute punctures, widely separated on the 

 fore-half of the elytron, more numerous, and becoming somewhat 

 rugulose towards the apex, especially near the outer angle ; the 

 5th segment, and part of the 4th and 6th segments, black ; the 

 surface with but few and extremely minute punctures. 



Male with a transverse row of six minute, short ridges near the 

 apex of the 6th abdominal segment ; the 7th segment gently 

 emarginate at the apex, and terminating in a long, acute tooth on 

 either side, the two teeth widely separated. 



This species is usually rather smaller than G. nana, and its 

 general colouring paler ; the intermediate joints of the antennae 

 are rather less transverse ; the punctures on the elytra are finer, 

 and less numerous, and the hinder part of the elytron is less 

 rugulose. The abdomen usually has the hinder half of the 4th 

 segment (at least), the whole of the 5th, and the fore-part of the 

 6th segment, black ; and the hinder-part of the 6th, and the whole 

 of the 7th segment, rufo-testaceous, like the base ; whereas, in 

 G. nana, the whole terminal half of the abdomen is usually dark. 

 The male characters, moreover, are very different in the two insects. 



Of the discoidal rows of punctures on the thorax, the second 

 puncture from the base in each row is the strongest, and one at 

 least towards the anterior margin is distinct ; the rest are indis- 

 tinct ; and following the rows of punctures are two very obscure 

 depressions. Besides these punctures are two or three punctures 

 on either side, one of which, near the posterior angle, is most 

 conspicuous. 



My specimens were found, in fungi, at Weybridge, in Sep- 

 tember ; and Dr. Power has taken the insect at Darenth, also in 

 fungi.
