Geodephagous Coleoptera of Japan. 215 



This curious species partakes of the characters of the 

 two groups C. campestris and C. germanica, but the 

 elytra are much more ovate than any other species 

 known to me, C. dromicoides only approaching it in this 

 respect. In the markings of the elytra it much resembles 

 C. Ismenia. The head is moderately concave between 

 the'eyes, and somewhat regularly and strongly striated 

 (more finely on the vertical forehead). The thorax is 

 long and narrow, very slightly narrowed behind and with 

 nearly straight sides, the surface vermiculate-rugose ; 

 the elytra are flattened and slightly explanated along the 

 sides, and remarkably convex in the middle at three- 

 fourths their length ; their sculpture consists in bluish 

 green punctures each surmounted (anteriorly) by a 

 minute shining granule, and in an irregular row of much 

 larger punctures each with a central golden point. The 

 body beneath is glabrous, excepting (in some individuals) 

 a few white hairs on the metasternum.

The typical form of this species, common in temperate 

 latitudes of Eastern Asia from the Amur to the Yang- 

 tsze, is, as described by Morawitz, 8% — 9§- mm. long, 

 and of metallic colours on its upper surface. The elytra 

 are punctured ; the punctures, though shallow, being 

 rendered conspicuous by being each on a bluish green 

 spot, contrasted with the coppery hue of the ground 

 colour ; and on the anterior margin of each puncture is 

 a minute bright speck, a rudimentary granule. As a 

 decisive character distinguishing this species from C. 

 literata and allies, I may mention that the trochanters 

 in all the legs are red. 



On the sea-shore of Hakodate, where Mr. Lewis on 

 his recent journey has met with this species, it occurs 

 in a high degree of development, some of the examples 

 measuring 11 mm., and being proportionately more 

 robust, with wider pale elytral markings and more 

 rounded thorax. In the same locality he found the 

 following allied form, sufficiently distinct to merit a 

 specific name : —
