 pale fulvous pubescence, at the insertion of the antennae it is 

 brighter, as well as that on the margin of the vertex ; the cly- 

 peus produced and truncate anteriorly. Thorax densely clothed 

 with rather long rich rufo-fulvous pubescence ; wings subhya-

 it has also been captured at Loch Rannoch.
