The beautiful D. concolor, so remarkable for its large (though 

 most variable) stature and its pale golden-testaceous hue, is widely 

 distributed throughout the Canarian archipelago — though every- 

 where sparingly. It is by no means peculiar to the Euphorbias 

 (at any rate in its imago-state); nevertheless I have taken it 

 from beneath the loose outer bark of those plants on the moun- 

 tains (towards Las Mercedes) above Santa Cruz of TenerifFe, as 

 also below Taganana, and in the rocky Eicpliorbia-cov ered ground 

 between the Puerto and Orotava- In Grand Canary it was found 

 in comparative abundance by the Rev. R. T. Lowe, during our 

 short stay at Arguineguin, in the south of the island ; and I have 

 likewise captured it near the mouth of the Barranco de Nogales, 

 on the east of Palma.
