This very beautiful Acalles is one of the most striking insects here described. The singular dilatation of the sides of the thorax and the numerous erect setae render it unmistakeable. I have dedicated it to M. Drouet, to whom we are indebted for the first exploration of these islands and for a careful summary of the results of his work, including three or four new species and eigth not since found.
