to wliich is another fine elevation that joins the outer of the two 

 coarse ribs some distance in front of the base, and just in front 

 of this junction is connected witli the line lateral margin by a 

 small elevation that causes the side of the thorax to appear 

 slightly denticulate ; in front of the base there is a very deep 

 transverse cavity that divides the two middle costse, but the in- 

 terruption is only brief, as the extremities of the divided costse 

 project somewhat over the cavity. The elytra bear very broad 

 deep grooves separated by very regular narrow interstices, the 

 summits of which are minutely crenate and furnished with exces- 

 sively minute setae ; the grooves bear two series of punctures 

 which are so nearly joined that, viewed in a particular direction, 

 they appear as a single series of large punctures or impressions. 

 Body beneath closely and coarsely punctate, quite dull. 



This is no doubt rather closely allied to Machlotes porcatus, 

 Pasc. ; but it diflers from the excellent description given of that 

 species in the sculpture of the under surface, and in some of the 

 details of the peculiar thoracic sculpture. 



Bare. JSTara and Nishimura on the main island, and Sapporo 

 in Tezo. In all four examples. 



Dastaecus LONaiTLUs, n, sp. (Plate III. fig. 9.) 



Oblongo-ovalis, elongatus ; prothorace vix transverso, elytris angustiore, 

 plagiatim fusco-squamoso ; elytris costatis, nigro-griseoque densius squa- 

 mosis. Long. 6-11 millim. 



Although very similar to D. porosus, this is readily distin- 

 guished by its more elongate form, and particularly by the less 

 transverse thorax, this being just about as long as it is broad at 

 the base. The individuals vary much in size and a good deal in 

 the coloration of the scales; the thorax is a little narrowed 

 behind, and has the sides very densely squamose ; there are also 

 two lines of scales along the middle, a more indistinct line near 

 the lateral margin, and a tubercular patch between the latter and 

 the middle. On each elytron there are four series of squami- 

 gerous costse, the scales of each being very dense, and variegate 

 in a somewhat irregular manner, the paler scales being most con- 

 spicuous at the base and apex, and forming an irregular fascia 

 behind the middle, 



Nine examples were met with at Konose in Higo, May l7th, 

 1881. Probably the species may not extend northward out of 

 Kiushiu
