928. A. prolixus, U.S. Elongate, narrow, depressed, sub-cylin- 

 drical, rather thickly covered with fine yellow setae ; slightly glossy, dark 

 red, legs and antennre dilute in colour, tarsi yellowish. Rostrum longer 

 than thorax, coarsely sculptured almost to its apex, punctate-rugose. 

 Head blackish, very coarsely punctate-rugose, very suddenly contracted 

 behind, cheeks rather prominent, its vertex distinctly more elevated than 

 the neck. Prothorax nearly twice as long as broad, very little rounded 

 laterally, rounded towa,rds its base, narrowed towards the front, where it 

 is slightly constricted, with the front margin a little raised and rather 

 smooth ; it is closely, coarsely, and rugosely punctured. Scutellum 

 transverse, smooth. Elytra but little broader than the thorax, very 

 long, parallel-sided, apex rounded ; they are punctate-striate, with rugu- 

 lose interstices, and appear rather rough. Z^o' clothed with fine hairs. 

 Under-side castaneous, metasternum impressed longitudinally. 



The insect must be thoroughly freed from impurities ; otherwise it 

 seems dull and rough.
