1272 NOTES ON AUSTRALIAN COLEOPTERA, 



shoulders are quite rounded off. The epipleurse of the elytra are 

 coloured as the upper surface. The whole undersurface is black 

 with a faint bluish tone and is moderately punctulate with a by 

 no means strong development of longitudinal wrinkles on the 

 lateral portions of the ventral segments. To specify the convexity 

 of the body it may be observed that the height (i.e., the distance 

 from the highest point, — the insect being viewed from the side, — 

 through the body to an opposite point on the surface of the sterna) 

 is to the length of the body as 13 is to 30. The foveee in the rows 

 on the elytra are much larger than in A. convexus, Pasc. 



Queensland ; taken by Mr. F. M. Bailey on the Bellenden-Ker 

 Ranges. 



N.B. — This species has the mandibles bifid at the apex and so 

 would appear to be a true Amarygmus. In shape it resembles A. 

 convexus^ Pasc, which moreover has similar mandibles and there- 

 fore must also be reckoned a true Amarygmus. 



Amarygmus uniformis, sp.nov. 



Sat elongatus ; minus convexus ; sat nitidus ; supra obscure 

 viridis, corpore subtus pedibus antennisque nigris ; capite pro- 

 thoraceque crebre subtiliter punctulatis ; elytris punctulato-striatis, 

 striis postice gradatim profundioribus, puncturis in striis apicem 

 versus obsoletis ; interstitiis subplanis, subtilissime punctulatis ; 

 prothorace quam longiori duabus partibus (postice quam antice 

 fere duabus partibus) latiori. [Long. 6, lat. 3 lines. 



An elongate-oval species with the shoulders of the elytra 

 well marked, the humeral angle being acute and quite prominent. 

 The punctures in the striae on the elytra are strong and rather 

 large except near the apex where they are almost obsolete, and 

 close to the base where they are small though deeply impressed ; 

 in the 3rd stria there are about 14 punctures from the base to the 

 point where they become very small behind the middle. The 

 sculpture of the underside is very similar to that in A. tardus but
