Leugtb 10 ; breadth 5 lines. 



Matiawatu Gorge. Named in honour of Mr. W. W. Smithy 

 who has lately contributed to our knowledge of the insect- 

 fauna of that region. 



Group HelopidsB. 

 Adelium hudsoni, sp. n. 



Elongate-oJdong, moderately convex, sparsely clothed with 

 minute greyish setse ; shining cupreo-fuscous^ the sides 

 more rufescent; legs castaneo-rufous, tarsi and antennae 

 ferruginous. 



Head narrower than thorax, forehead evenly curved ; 

 rather finely and irregularly punctate. Thorax quadrate, 

 almost as long as broad^ its sides finely marginate and 

 nearly parallel, being only gently rounded near the slightly 

 prominent anterior angles, apex a little incurved, base sub- 

 tiuncate, posterior angles nearly rectangular and resting on 

 the elytra ; its punctuation distinct, rather fine^ somewhat 

 irregular, nowhere close, rather finer at the sides, a basal 

 impression near each side most closely punctured ; there is 

 a slight elongate lateral impression before the middle, and 

 about a dozen foveiform punctures are distributed over the 

 disk. Scutellum broad, minutely punctate. Elytra elongate, 

 rather wider than thorax at the base, very gradually narrowed 

 backwards, but evidently more attenuate apically ; each 

 elytron with about twelve distinctly punctured striae, these 

 are not always regular, sometimes the punctures are more 

 conspicuous than the striae, yet even these are interrupted on 

 certain spots, all, however, are much deeper and confused 

 towards the extremity ; the interstices bear series of minute 

 punctures, they are only of moderate width and, on some 

 parts, partake of the partial irregularity. 



Underside glossy fuscous ; the sides of prosternum, coxfe, 

 epipleura, and terminal ventral segment rufo-castaneous ; 

 abdomen rather finely reticulate-punctate ; middle of the 

 prosternum compressed, its flanks finely irregularly strigose. 



Near A. cheesemani and A. simplex. In the former the 

 elytral striae are more distinct and numerous, about twenty 

 on each elytron, the thorax difl"ering in form, being more 

 deeply incurved at the base and apex and more rounded 

 laterally. A. simplex I have not seen, but its description 

 indicates a much less brightly coloured insect, with different 

 sculpture. 



Length 4-4^ ; breadth 1^ line.
