feeble whitish spot on the third interstice at the basal third. 

 On the under-surface the ochreous scales are almost confined to- 

 the three apical segments. 



ExiTHius BREvis, Lea. 



The type of this species was somewhat abraded. Speci- 

 mens in perfect condition have the scales mostly deep-blacky 

 more especially those forming the rather numerous fascicles. 

 The species appears to be fairly common on the Blue Moun- 

 tains; and two specimens from that locality have two small 

 white spots on the elytra at the summit of the posterior 

 declivity, one of these having in addition two small median 

 spots. The rostrum is conspicuously notched on each side of 

 the base. 



Following is a table of the species : — 



A. Prothorax conspicuously dilated in front ... 

 A A. Prothorax not so dilated. 

 B. Femora edentate. 



a. Scutellum distinct 



aa. Scutellum indistinct or absent. 



fc. Prothorax with large punctures, 



usually sharply defined 



hh. Prothorax with smaller punctures, 

 more or less concealed, 

 c. Each elytron with three conspicuous 

 fascicles, aln^ost in line with 



suture 



cc. Elytra without such fascicles 

 BB. Femora dentate, 



C. Scutellum very distinct. 



d. Shoulders conspicuously projecting. 

 e. Elytra less than twice the length 



of prothorax 



ee. Elytra more than twice the length 



of prothorax 



dd. Shoulders not conspicuously pro- 

 jecting. 

 /. Each elytron with a conspicuous 

 lateral patch of whitish scales ... 

 ff. Elytra not so clothed. 



g. Suture without granules near base 

 gg. Suture with a few granules near 

 base. 

 h. Posterior declivity rather 



elongate 



hh. Posterior declivity rather 

 abrupt. 

 i. Prothoracic scales variegated 



along middle
