6 Mr. D, Shai'i) on some 



he does not allude in any way to the sternal structure — 

 the most important of all the characters in this group — 

 it is impossible to come to any decision on the point. 



Mesanohium debile, n. s. 



Fuscum, supra rufescens, antennis pedibusque rufis, 

 corpore supra opaco, dense subtilissime sculpturato, pube 

 tenuissima depressa vestito. Long. 2 — 2;^ mm. 



Prothorax a good deal narrower than the elytra, above 

 about as long as broad, convex, rather narrowed from 

 the middle towards the front ; surface sculptured with 

 very dense, fine, minute, granulations. Elytra very 

 finely granulose, like the thorax, but possessing in 

 addition numerous very minute and obscure small 

 punctures, giving rise, under careful examination, to the 

 appearance of a rudimentary striation. Ventral seg- 

 ments finely, closely, and evenly punctate. 



Found by Mr. Helms at Greymouth. I have three 

 individuals before me, but I can detect no certain 

 sexual differences. 



Dasytes helmsi, n. s. 



Elongatus, angustulus, postice latior, opacus, supra 

 purpureo-niger ; subtus niger, violaceo-tinctus ; antennis 

 nigris ; supra tenuissime pubescens, elytris crebrius 

 parum argute punctatis. Long. 6 mm. 



Antennae extending quite to the hind margin of the 

 thorax, black, a little thickened towards the extremity, 

 the penultimate joint not twice as long as broad. Head 

 rather elongate, about half as broad as the wing-cases, 

 narrowed behind the eyes. Thorax nearly as broad as 

 long, much constricted in front, the basal and lateral 

 margins very distinct, but the latter becomes indistinct 

 at the anterior constriction or impression, the surface 

 very indistinctly punctured and finely pubescent. Elytra 

 closely and rather finely punctate, but the punctuation 

 indistinct, although somewhat rugulose ; the pubescence 

 very indistinct. Legs long and slender, nearly black 

 above, deep blue beneath. 



Although very different in colour from D. wakefieldi, it 

 is in form, and probably in structure, closely allied 

 thereto.
