Hob. Moreton Bay, Austi'alia. 



Head sparingly clothed with short, adpressed, white hairs j 

 vertex and front impressed with a longitudinal groove ; the 

 former rather closely punctured ; the latter semiovate, concave ; 

 lower part of face and clypeus rugose ; eyes moderately dis- 

 tant ; antennae rather more than half the length of the body ; 

 five outer joints moderately thickened, each nearly twice as 

 long as broad, six upper ones black. Thorax twice as broad 

 as long ; sides only slightly converging from the base to the 

 middle, thence rounded and converging to the apex ; basal 

 margin bisinuate on either side, median lobe moderately pro- 

 duced, obtusely angulate ; upper surface finely and subremotely 

 punctured. Scutellum obovate, its apex acute. Elytra dis- 

 tinctly punctate-striate; interspaces plane, minutely punctured ; 

 here and there (when seen under a strong lens) transversely 

 rugulose ; two outer interspaces very slightly convex. Body 

 beneath and legs more or less stained with piceous. 



Ditropidus amahilis. 



D. breviter ovatus, valde convexus, piceus, nitidus, antennis basi 

 fulvis; pedibus (fetnoribusposticis exceptis) abdomineque obscure 

 fulvis, hoc piceo tincto ; thorace seneo micante, minus remote, ad 

 latera crebrius punctato, punctis oblongis ; elytris flavis, sat forti- 

 tcr punctato-striatis, punctis piceis ; striis quarta et septima, 

 quinta et sexta, octava et nona apicibus per paria coeuntibus ; 

 interspatiis planis, ad apicem et ad latera vix convexiusculis. 



Long, i lin. 



Hah. Cape York, Australia. 



Head clothed with adpressed whitish hairs ; eyes moderately 

 distant ; clypeus broader than long, its upper margin angu- 

 late. Thorax nearly twice as broad as long ; sides obliquely 

 converging and slightly rounded from base to apex ; basal 

 margin slightly bisinuate on either side, median lobe produced, 

 obtusely angulate ; upper surface distinctly punctured, the 

 puncturing rather coarser and more crowded on the sides. 

 Scutellum ovate, its apex acute. Elytra with its basal mar- 

 gin, together with that of the thorax, narrowly edged with 

 nigro-piceous. 



Ditropidus suhmetallescens. 



D. breviter ovatus, valde convexus, piceus, nitidus, supra ajneo 

 micans, antennis basi pedibusque (tarsis exceptis) obscure piceo-
