 finely shagreened; antennae short and robust, their first two joints thick, 

 the third obconic and smaller than the second, the middle and next-last 

 (4-10) increasingly transverse and these more than twice as broad as long, 

 distal joint short. Pronotum a little narrower than elytra, anteriorly a 

 little broader than lon^, feebly narrowing posteriorly, with rounded off 

 hind corners, extremely fine isolated punctation, medial line slightly 

 grooved and at middle more or less broadly depressed; elytra li times as 

 long as pronotum, particularly finely and densely punctated, their posteri- 

 or margin inside the outer corners not incurved; abdomen of equal breadth, 

 its first four free dorsal joints depressed at base and with rather fine, 

 scattered punctation, the following almost irapunctate. The sixth is, pe- 

 culiar for this species, at tip divided into three spines, of which the 

 middle one is longest. L. 1.5 mm. 



In the o the second, third and fourth free dorsal joints of abdomen 

 at each side on dorsum with a small acute granule (Fig. S3). Pronotal lon-- 

 gltudin*l impressions are more distinct and the middle spine of the sixth 

 tergite much longer than in the o . 



Distributed in all our forest regions and not rare under bark on in- 

 fested trees and stubs, but easily overlooked.
