D. undulatus, Brahm. {tesselWus, W. C, nee F.). Closely allied 

 to the preceding, but on the average smaller, and easily distinguished by 

 the yellowish or yellowish-brown pubescence of the head, thorax, and 

 base of elytra, and the reddish or pitchy-red antennae ; the under-side is 

 thickly clothed with wlitish pubescence, but the last segment is furnished 

 with two white spots at base instead of three as in D. murinus ; in shape 

 the two species much resemble one another except that the thorax is 

 longer in I), imdulatus. L. 6-7 mm. 



In dead birds, fish, &c. ; usually found on the coast ; local ; Whitstable, Sheerness, 

 Southend, Folkestone, Dover, Deal, Hastings, Slioreham, Brighton, Devon, Swansea;

In hides, bacon, natural history specimens, dead animals, &c. ; more local than is 

 generally supposed, but far too common ; it is rarer out of doors than in bouses, 

 warehouses, &c. ; it appears to be generally distributed tbi-oughout England and 

 Wales, and probably Ireland, but Sliaip records it as i-are in Scotland iu the Tweed, 

 Forth, Clyde, and Dee districts.
