exhibit no well-marked variations. Nos. 647, 648, and 649 

 occur amongst alga3 along the east side, whereas C.fuscatus 

 was found on the opposite coast.

Group DiaperidaB. 

 Menimus Ifevicolh'sj sp. n. 



Convex, oval, shining, minutely pubescent ; nigro-piceous, 

 legs and antennae pale red, lateral margins and front of head 

 rufescent. 



Head distinctly but not coarsely punctured. Thorax 

 transverse, gradually and a little curvedly narrowed towards 

 the front, the margins there thinner than at the base ; dis- 

 tantly, quite minutely, and indistinctly punctured; base 

 subtruncate, apex slightly bisinuate. Scutelluni short, not 

 smooth. Elytra attenuated and narrowly marginated poste- 

 riorly, of the same width as the thorax at the base, slightly 

 wider behind the shoulders, with numerous almost regular 

 rows of moderately coarse punctures, these become finer 

 behind and are least regular near the base ; a few minute 

 grey hairs can be detected. Legs with yellowish pubescence, 



ilnderside distinctly punctate, sparsely pubescent. Pro- 

 sternum nearly smooth and a little concave along the flanks ; 

 its process moderately narrow, horizontal, and attaining the 

 base. Mesostei-num slightly raised and rather smooth in the 

 middle. 



The specimens I possess cannot be referred to M. duhius, 

 which they most resemble, because the punctuation of the 

 head and elytra is evidently coarser and the eyes are rather 

 smaller, though not at all minute, as in some species. It 

 may be distinguished from M. Batesi, Sharp, by the rather 

 shorter form and obsolete thoracic sculpture. In one example 

 the femora are yellow.

Tarukenga. Ten individuals found on the underside of 

 decaying logs. 



Obs. In this genus the prosternal process passes over the 

 mesosternum and touches, or nearly touches, the suture 

 between the middle coxse when the body is bent ; when 

 relaxed and straightened the mesosternum is uncovered. 

 There is no saltatorial power.
