less distinct and less circular in outline, and each bears a 

 single grey hair between the punctures, the surface is micro- 

 scopically granulate ; the legs, tibije in both sexes are dilated 

 after the manner of a Fedinus, but the male has the second 

 and third joints of the tarsi on the anterior and intermediate 

 feet very wide and transverse, as stated above. 



llah. Kobe. Abundant under seaweeds on the sandy 

 sea-coast. 



Micropedinus jyallidipennis, sp. n. 



J/. aZ/7fC'simillimus, sedpiceus vel brunneus ; elvtris pallidis, $ tibiis

This species is extremely similar to the last, but it is 

 smaller, and the elytra are generally pale in colour. Some- 

 times the whole insect is of a Hglit brown colour, but there is 

 a variety in which the dorsal area is dark. Structurally it 

 differs from M. algce in the antenna being shorter with the 

 articulations more compressed, in the thorax being less trans- 

 verse, and, above all, in the anterior tibias in the female not 

 being dilated near the tarsi. 



Hah. Kobe. Associated with M. algce. 



Opatrum expansicoUe, sp. n. 



Nigrum, opacum, supra granulatum ; thorace lato, marginibus ex- 



planatis ; elytris tenuiter pimctato-striatis. 

 L. 11-11^ mill. 



Dull black, opaque, granulate; the head widened and 

 thickened before the eyes, emarginate anteriorly ; the thorax 

 explanate laterally, edge rounded off from the anterior angle 

 nearly to the base, posterior angles slightly turned outwards ; 

 the elytra, strife when visible fine and punctate, in many 

 examples the strife are obsolete, interstices granulate like the 

 head and thorax ; the antennae, two basal joints pitchy red. 



This species differs from all in this series in the shape of 

 the thorax. 



Ilab. Kiga, Kob^, Arima, and on Maiyasan. 



Opatrum oi-ariurii^ sp. n. 



Atrum, opacum, oblongo-ovatum, granulatum ; capite sccuriformi, 



ante oculos angulato : elvtris obsolete striatis. 

 L. 10 mill.
