The general aspect of the unique insect from which the above cha- 

 racters have been drawn, combined with its posteriorly narrowed pro- 

 thorax, its bifid (or internally dentate) claws, and the tendency of its 

 larger elytral punctures to arrange themselves in longitudinal rows, 

 will at once, apart from the minutice. of its oral organs, affiliate it with 

 the European LithophUus (a near ally of Coccidula) ; and as I have 

 no access to any published details of that genus, I have thought it 

 desirable to enunciate it formally. In its i^Ji-jointed antennte (with 

 their elongated third articidation), its very much larger size, and its 

 totally different pro thorax (which is deeply excavated in front, greatly 

 rounded, and flattened out, at the sides, and much more contracted 

 behind), as weU as in its longer and robuster legs and claws, it is at 

 once separated from Coccidula proper.

The single siiecimen described above was captured by myself, from 

 beneath a stone, in the dry sandy region at Corralejo, in the extreme 

 north of Euerteventura, at the end of March 1859.

This common European insect, which abounds beneath vegetable 

 refuse in Madeira, and which was captured by Mr. Bewicke at even 

 the Cape of Good Hope, appears to be scarce in these islands ; though
