 about twice as broad as lonj; distal joint slrort, tapering. Pronotum 

 is much narrower than elytra, 1 '/^ times as broad as lonj^, with anterior- 

 ly' slightly rounded sides, posteriorly distinctly narrowing, with rather 

 fine and dense, flat punctation, at middle posteriorly most often with 

 slight, flat depression, sometimes feebly grooved at medial line; el- 

 ytra nearly la times as long as pronotum, with very dense and rather ro- 

 bust, granulate or scabrous punctation. The first four free dorsal joints 

 of abdomen rather deeply transversally grooved at base, the first three 

 at base with dense and rather fine, the hindmost half with less dense 

 and fine, granulate punctation, the two following joints with isolated 

 and rather robust, granulate punctation. L. 3-3.5 mm. 



In the ^ the sixth free dorsal joint of abdomen with coarse and dense 

 jranulate punctation; this punctation as a rule bounded by four distinct 

 jranules posteriorly before the hind margin; the posterior margin is flat- 

 ened and smooth with rounded posterior edge, which at middle most often 

 has a sharp Incision. - In the Q the joint is formed and punctated simi- 

 larly, but less distinctive, posterior margin as a rule entire. 



It lives in the leaf sheaths of cat tail ( Typhti latifolia ), apparent- 

 ly preferring such plants of which the stems are bored by the larva of the 

 noctuids ( Nona.^ria typhae or cannae ) , and may be taken numerously here. 

 Distributed, and in this country not rare in bo.;s, ponds and lakes, where 

 the cat tail grows; often also in alluvium at such places.
