1. Corticaria pubescens. C. oblonga, convexa, longius .pubescens, 

 antennis pedibusque flavescentibus ; tborace cordato, supra 

 densius punctato, postice foveolato, lateribus denticulate ; 

 elytris amplis, crebre seriatim punctatis.

The largest of the British species, and further distinguished by 

 its smallish short cordiform thorax, and ample elytra with closely 

 packed rows of punctures. The anterior tibiae are quite straight 

 and simple in both sexes, and there is no difference in the anterior 

 tarsi indicative of sexual distinction — or at least it is very indis- 

 tinct — for in some specimens I fancy I have noticed the basal joint 

 is rather larger than in others. The antennae have the joints more 

 elongated than in the species next to be noticed. Its colouring 

 varies considerably : most commonly the head and thorax are 

 fusco-ferrugineous, the elytra piceous, becoming paler in the 

 region of the shoulders. Sometimes the whole insect is piceous 



• It is not my intention here to enter into the question of prioiity of names, 

 &c. ; I have retained throughout this paper the names most commonly used, other- 

 wise I should have been inclined to apply Rlarsham's name to the present species. 

 The oldest name given among the synonymes of this i^pecies is "fenestra lis," of 

 Fabricius, but there does not appear to be any good evidence that it really belongs 

 to our insect ; then next in date comes the name " longicornis" of Herbst, but 

 as Herbst has given the same name to another species — a name universally 

 adopted for that species — we would pass that over, and come to the next oldest 

 name, and that is " punclidata'' of Marsham. 'J'here can be no reasonable doubt 

 about Marsham's species, which was published in 1802; whilst the name "pu- 

 bescejis" was published first by Gylleahal in 1827.
