There are faint indications of pubescent spots on tbe sides 

 of tbe abdominal segments, which would possibly be well de- 

 fined in a fresh specimen. 



CISSEIS. 



C. nuhecidosa, Grerm. I have long had a suspicion that this 

 .and AT. cJialcopteriwi, Germ., could not be satisfactorily 

 separated, the latter being distinguished by their author only 

 by size, colour, and the absence of certain impressions from the 

 head and thorax. In the last-named respect 31. nubeculosa 

 itself varies not a little. The question has, however, been set 

 at rest by Mr. J. Gr. O. Tepper, who has shown me two speci- 

 mens taken pairiug, one of which is evidently C. nubeculosa and 

 the other C cliaJcopteonini. He assures me that he has frequently 

 found the two forms pairing together. 



■C obscura., sp. nov. Minus convexa ; senea ; supra quam subtus 

 multo minus nitida ; abdomine glabro ; elytris obscure 

 aureo pubescentibus postice subcupreis , capite sat crebre 

 fortius punctulato, postice undatim rugato, medio vix evi- 

 denter canaliculate ; prothorace vix dimidio latiore quam 

 longiore, antice minus fortiter angustato subtruncato, 

 postice leviter bisinuato, sequali, crebre subtiliter cur- 

 vatim rugato, lateribus sat rotundatis ; elytris crebre sub- 

 tiliter rugose punctulatis, lateribus postice subtiliter 

 serratis. Long. 3 1. 



This little species resembles C notulata, Germ., and 

 C. roseocujorea, Hope. It is a flatter and proportionately wider 

 insect than either of them, and also differs from them both in 

 the perfectly even surface of its thorax, which is entirely 

 devoid of impressions, in the absence of pubescent spots from 

 the abdominal segments, and in the arrangement of the pubes- 

 cence on the elytra, which is evenly though obscurely spread 

 (giving those organs an appearance of being frosted) saving 

 that there are some denuded spaces forming a vague irregular 

 fascia near the front, a second behind the middle, and a third 

 occupying the apex ; there is no trace at all of the spots of 

 pubescence which are present in all the specimens I have ex- 

 amined of the other two species mentioned above. C. obscura 

 is also distinguished from them both by the considerably finer 

 :and closer puncturation of its elytra, from G. notulata by the
