M. Derbyensis, sp. nov. Supra viridi-aurea, subtus viridis vix 
auratus; nitida; fere glabra; capite plano confertim fortiter 
punctulato et pilis brevibus albidis dense vestito; prothorace 
quam longiori duplo (postice quam antice fere tertia parte) 
latiori, nullo modo canaliculato, sat fortiter minus crebre 
latera versus magis crebre (fere ut J. vernw, Hope, sed 
paullo minus fortiter) punctulato, lateribus vix arcuatis, 
margine antico leviter emarginato vix bisinuato, basi 
bisinuata, angulis posticis sub acutis leviter retrorsum 
directis: elytris punctulato-striatis, latera versus striis obso- 
letis et puncturis confusis, interstitiis suturam versus 
subtilissime sparsissime punctulatis, lateribus postice denti- 
culatis; prosterno antice declivi. Long., 54.1.5; lat., 21 
The prothorax scarcely differs from that of J. verna, Hope, in 
any respect except that the front margin is scarcely at all 
bisinuate, and that the puncturation is a trifle finer. The elytra 
are very much more distinctly striated than in that species, the 
nterstices of the striz being almost levigate. The puncturation 
of the underside is evidently finer than in I. verna. The follow- 
ing characters in combination will, 1 think, distinguish it from 
all its described congeners; colour of upper surface bright 
greenish-golden, head flat, pubescent and very closely punctured, 
prothorax without any trace of a dorsal line beyond a faint 
scratch at the base only discernible in certain lights, elytra quite 
devoid of coste, but exceptionally distinctly striate.
