Of this minute Anohium, which has much the colour and prima 

 facie aspect of a Crujptophagus, I have seen hitherto but a single ex- 

 ample — which was taken by myself, during February 1858, in a 

 sandy lane at a very low elevation in the district of El Golfo, on the 

 western side of Hierro. It is remarkable for its reddish-brown hue 

 and rather shining and sericeous surface, for its oblong-ovate outline, 

 for its prothorax being even and subcorneal and not at all margined 

 (or expanded) at the sides, and for the last three joints of its antennae 

 being rather less elongated than is the case in the generality of the 

 true Anohia.

The excessive dissimilarity of the sexes of this insect renders it 

 absolutely necessary to give a separate diagnosis for each of them, 

 since they have scarcely a single feature in common. In my Paper 

 on the Canarian Anobiadw I queried it as probably identical with the 

 Madeiran P. cylindripennis, of which I did not, at the time, happen 

 to possess a type for comparison. A subsequent examination, how- 

 ever, of the two proves them to be unquestionably distinct ; for al- 

 though they do not differ materially in their male sex (which indeed, 

 in both cases, has much the prima facie aspect of the common Euro- 

 pean P. pectinicornis) , the females of the P. lepidus, when closely in- 

 spected, wlU be seen to have nearly all their characters considerably
