1885.] COLEOPTERA FROM JAPAN. 199 



spilota, Balv, but differs in its less elongate and more square shape 

 and in the differently sculptured elytra ; the latter show immediately 

 below the middle, near the suture, an apparently deeply excavated 

 space, caused partly by the strongly raised principal ridge, which 

 limits this space laterally : the anterior portion of the elytra within 

 the ridge only shows a few very small tubercles near the suture ; in 

 C. spilota there is a distinct tubercle in the corresponding portion ; 

 the elevate ridges are but slightly raised and the excavated space 

 below the middle is wanting. 



Chlamys spilota, Baly. 



Of this specie?, a variety obtained at Miyanoshito is of nearly 

 entirely fulvous colour, the thorax being transversely spotted with 

 black. C. spilota may be separated from other allied forms princi- 

 pally by the gibbous or posteriorly elevated shape of the thorax ; 

 this elevation or bump is somewhat conically shaped and is not 

 divided at the middle by a longitudinal channel, so frequently the 

 case in other species, although the apex of the tuberosity is faintly 

 sulcate. Another normally coloured specimen of this species was 

 obtained at Nakone. 



Genus Cryptocephalus, Geoffr. 

 Cryptocephaltjs limbatipennis, n. sp. 



Black : clypeus, anterior and lateral margin of the thorax and two 

 basal spots of tlie latter yellow ; basal joints of antennae and the 

 legs fulvous ; thorax rugose-punctnte at the sides ; elytra strongly 

 punctate-striate, black, the lateral margins narrowly flavous. 



Length Ij line. 



Head closely and distinctly punctured, black ; the clypeus, labrum, 

 and part of the sides below the eyes flavous ; antennae black, the 

 five basal joints fulvous, fourth joint slightly longer than the third. 

 Thorax about twice as broad as long, the sides nearly straight, pro- 

 duced in a point at the posterior angles ; surface closely covered with 

 distinct and somewhat elongate punctures, confluent and forming 

 elongate and deep strigae attlie sides, the anterior and lateral margins 

 narrow, yellow, the former with a slight indentation at the middle, 

 which intrudes into the black-coloured portion ; at the base, imme- 

 diately above the scutellum, two closely approached fulvous spots are 

 |ilaced. Scutellum elongate, raised behind. Elytra with regular 

 rows of deep and not very closely approached punctures, which get 

 less deep below the middle but are distinct to the apex, the latter 

 of which is covered closely with other fine punctures ; interspaces at 

 the sides below the shoulder here and there somewhat transversely 

 wrinkled ; humeral callus very prominent, the extreme base im- 

 punctate ; the colour of the disk entirely black, the lateral margin 

 narrowly flavous, this colour is slightly widened at a place near and 

 below the middle. Pygidium black, margined with yellow. Legs 

 entirely fulvous.
