The females of this species are strongly and coarsely punc- 

 tured on the disk of the prothorax and on the elytra. The 

 antennffi do not reach quite to the middle of the elytra, and 

 their last joint is short, scarcely, if anything, longer than tiie 

 preceding joint. 



The males are slightly less strongly sculptured ; their 

 antennffi reach beyond the middle of the elytra, and have the 

 last joint distinctly longer than the preceding. 



I have already mentioned that all the specimens of E. 

 lineata and E. punctata in the British Museum collection 

 are females. All the specimens of E. fuh'qi'nosa, Fabr., and 

 E. suhpunctata, Chevr., are, on the other hand, males. 

 From these facts I have been led to suspect that E. fuligi- 

 nosa, Fabr., is the male of E. lineata^ Linn. ; and this 

 suspicion has been strengthened by finding that all the white- 

 striped specimens of Elateropsis in the collection of Mr. 

 Alexander Fry, who very kindly sent me the whole of his 

 Solenopterinas for examination, are also females, while the 

 unstriped glossy specimens referable to fnliginosa and suh- 

 punctata are males. ] have thus seen altogether twenty-two 

 specimens, all females, of the three white-banded species 

 mentioned above, and eleven specimens, all males, of E. fuli- 

 ginosa, Fabr., and its questionable variety E. suhpunctata, 

 Chevr. 



If it is proved to be the case that the white bands in the 

 species of this genus are confined to the females, then it is 

 very likely that some of the less strongly punctured speci- 

 mens which I now regard as males of E. scahrosa are really 

 males of E. punctata. 



In E. ebenina, Chevr., there is no marked sexual difference, 

 the males having the antennae slightly longer than in the 

 females, with the last joint relatively somewhat longer.
