A NEW BEITISH SPECIES OF PTILIUM (COLEOPTERA). 

 BY H. BRITTEN, F.E.S. 



JPtilium asperu7n, n. sp. 



Elongate-oval, fuscous, clothed with moderately long greyish hairs; head 

 large, very finely and thickly tuherculate ; eyes prominent ; antennae mode- 

 rately long, pitch}' ; thorax wider than head, broadest in middle, sides strongly 

 rounded in front and constricted behind, hind angles projecting, covered with 

 thickly-set large tubercles ; elytra elongate-oval, broadest at middle, strongly 

 asperate in irregular transverse rows ; legs dirty yellow. Length |-| mm. 



This species at first sight closely resembles a large example of 

 P. spencei All., but is easily distinguished bj its basally constricted 

 thorax, the much coai-ser sculpture of the thorax and elytra, and the 

 shorter greyish hairs. In shape it resembles P. caledonicum Sharp, but 

 is at once separated from that species by its stronger sculpture and dark 

 colour. 



I have made drawings of the male aedeagus as seen from the front 

 and side, with another, to the same scale, of the aedeagus of P. mar- 

 ginatum Aube, drawn from a side view, 

 to show the very different outline and 

 much smaller size in the latter species, 

 though the insects themselves- are 

 similar in dimensions. The aedeagus

ably from that of an}' of the other 

 members of the genus I liave examined. 



The description is taken from a male captured in an old squiiTeFs 

 drey at Great Salkeld, Cumberland, 19. vi. 1913. Another specimen of 

 the same sex was taken in fungi in the New Forest, 4. viii. 1914. A 

 third, fomid in Scotland by Mr. N. H. Joy, has also been examined by 

 me, but the sex of this example has not been ascertained.

It appears evident that the above-named species as understood on 

 the continent is a different insect to that described as A. tiprsi color bv 

 Wollaston in his revision of the British species of the genus (Trans. Ent.
