H. crenatus, /. Of rather short and broad form, convex, black, 
somewhat shiny, subglabrous; antenne ferruginous or pitchy ferru- 
ginous, with the scape and funiculus furnished with very long ciliate 
hairs on their external margin, the funiculus being as long as the club ; 
thorax slightly transverse, with the sides narrowed and somewhat com- 
pressed in front, coarsely and somewhat granulosely punctured in front, 
less closely and more distinctly behind; elytra with very strong crenate 
strie, interstices very rough muricate or tuberculate, with the punctures 
of the striz almost meeting in places; legs black or pitchy, with the 
tarsi usually lighter; the colour is usually deep black, but the elytra are 
often more or less reddish and occasionally ferruginous. L. 4-5 mm.

* Mr. Blandford says of this insect : ‘‘I believe this is really a very injurious 
insect when it occurs; I have often found it in well grown dead ash trees, which 
showed no signs of injury or decay beyond the presence of this insect ;”’ Eichhoff has 
remarked the same; in young trees the very long horizontal galleries of the larvae 
may completely encircle the tree, thus entirely cutting off the circulation.
