 In the o the femora are somewhat more robust than in the Q . and 



hind femora on inner side at base with a short spine or tooth. Meta- 

 sternum is flat, but scarcely long-haired; abdominal second and third 

 ventral joints smooth in middle-line, the fourth posteriorly slightly 

 impressed and smooth, the fifth more broadly and deeply impressed, po- 

 steriorly smooth, the sides of impression in both joints with sparse 

 long hair, in the fifth joint posteriorly elongated acutely dentiform, 

 posterior margin broadly roundedly incurved; the sixth joint is at mid-

Distributed in North and Middle Europe, but everywhere rare; with 

 us it is very rare (Slagelse, Odense), at the edges of water and on 

 nieadov. ground in alluvium and in remains of haystacks. In Skaane it is 

 found in the vicinity of Helsingborg (Thorns.). 



Closely allied to St. sylvester Er. is St. excubitor Er. (Kaf. Mk. 

 Br. I, 551; Kraatz Ins. D. II, 769; Thorns. Skand. Col. II, 218; Canglb. 

 Kaf. M. II, 568). It is about of 6ame size, rather strongly glistening, 

 more distinctly whitish haired, the thorax more robustly, but less dense- 

 ly punctated; the head is broader, as broad as elytra, pronotum without 

 distinct groove in middle-line, elytra smooth. - In the o only the ab- 

 dominal fifth ventral joint is posteriorly impressed and smoothed and 

 the posterior margin feebly emarginated; the sixth at middle with iso- 

 lated punctation and at tip with a short angular incision. L. 3.5-4 mm.
