»4 MANDIBULATA. COLEOPTERA. 



Sp. 4. arcuatus. Pallide testaceus autjlavescens, pectore nigricante, rostro Ion- 

 giori, apicefusco, elytris profunde punctato-striatis. (Long. corp. 3 liu.) 



Cu. arcuatus. Panzer? — Do. arcuatus. Steph. Catal. 166. No. 1690. 



Pale testaceous or flavescent^ slightly pubescent : thorax rather obscure, punc- 

 tate: elytra shining, deeply punctate-striate, immaculate; breast dusky; 

 rostrum rather long, fuscous at the tip : femora rather acutely dentate. 



Panzer, in his description of this insect, says "femora mutica;" but as his figure 

 represents them dentate, I have little hesitation in refen-ing it to this insect: — 

 its vastly superior size manifestly distinguishes it from the following, which 

 it at first sight greatly resembles. 



Found occasionally within the metropolitan district in June on 

 willows. 



Sp. 5. pectoralis. Rufo-testaceus, cinereo-pubescens, pectore nigricante, rostro 

 longiori punctato, apice fusco, elytris cinereo fuscoque variegatis. (Long, 

 corp. 2 lin.) 



Cu. pectoralis. Panzer. — Do. pectoralis. Steph. Catal. 166. No. 1691. 



Rufo-testaceous, slightly cinereo-pubescent : forehead impressed: eyes dusky- 

 black : thorax abruptly coarctate, rather coarsely punctate : elytra somewhat 

 deeply punctate-striate, variegated with a dense ashy-white pubescence, and 

 with obsolete fuscescent denuded spots on the disc : breast dusky-\)\&(^ or 

 piceous, abdomen dull ferruginous, sometimes fuscescent at the base: legs 

 rufo-testaceous, femora robust, with a stout tooth: rostrum rather slender, 

 long, punctate, with the apex fuscous. 



Taken near London in June and July, but not abundantly, on 

 the willow.

 lisque fusco-brunneis, elytris convexioribus oblongo-ovatis. (Long. corp. 1^ —

Rufo-testaceous, with ashy pubescence : head ferruginous : eyes black : thorax 

 a little coarctate anteriorly, the disc very finely punctulate: elytra ferrugi-

Far from uncommon within the metropolitan district, frequenting 

 willows and poplars. "Taken in the neighbourhood (of Swansea)
