250 Mr. G. R. Waterho use's Descriptions of the 



terminal (dilated) joints of the antennae fuscous or pitchy; elytra 

 testaceous, more or less broadly margined with black at the sides 

 and base ; head destitute of punctures, or very nearly so ; thorax 

 strongly transverse, with two distinct punctures on the hinder 

 part of the disc, and pretty widely separated; the other punctures 

 of the dorsal series either wanting or indistinct; elytra smooth, or 

 very nearly so. 



Male with the 6th abdominal segment destitute of evident 

 ridges; the 7th segment gently emarginated, and terminated on 

 either side by a tooth which is stoutish at the base, and has the 

 apical half slender ; the length of this process is about equal to 

 half the diameter of the interspace. 



G. lucidula is about half the size of G. nana, but agrees very 

 closely with that insect in general form and proportions; the inter- 

 mediate joints of the antennae, however, are less strongly dilated. 

 It is distinguished by its general black hue ; the head, thorax and 

 abdomen being entirely black, and the black on the elytra is more 

 extended than in G. nana and its immediate allies. Here the 

 dark colour is not only seen on the sides and apical angle of the 

 elytra, but likewise on the basal portion. It is more or less ex- 

 tended in different individuals, and in some the pale colour of the 

 inner part of the elytron is reduced to a small area. The antennae 

 are darker than in other species, being usually pitchy-black, with 

 the base only testaceous, and this pale colour is often confined to 

 the basal joint. The punctures of the dorsal series are reduced 

 in number and are small and indistinct, if we except the sub-basal 

 pair, which are as usual large and evident. The elytra and abdo- 

 men are nearly smooth — with a very strong lens only a ^evi ex- 

 cessively minute punctures being visible. 



I have taken this insect rather plentifully in vegetable debris in 

 the Hammersmith Marshes, near London. Dr. Power has also 

 met with it in similar situations at Lee and Eltham. I am not 

 aware that it is found in fungi.

 transverse, with punctures irregularly scattered over the surface.
