Distributed in Middle iiiurope; rare in this country; at outflowing tree- 

 sap, especially of elm. (fraderiksvaerk, Eoserup, Nyk^bing F., Assens, Als 

 et al. - also in Skaane (Thorns)). 



A closely allied species, S. rubra Er. is distributed in Central Eu- 

 rope. It is vivid brownish-red with darker, often pitch-black head and 

 abdomen. Hind corners of pronotum strongly defined, almost rectangular. 

 In the Q the fifth free dorsal joint of abdomen with two parallel longi- 

 tudinal carinae at middle, and the sixth at posterior margin with a row 

 of small acute teeth, of which the outer one on each side is longest. L. 

 3.5-4 mm. 



It lives especially in fungi, reported as not rare (Janglb.) and may 



possibly also occur in this country. 



35. Jenus Suryusa Er. 



(Srichs. Kaf. Mk. Br. I, 371; (Jen. Spec. Staph. 199; Kraatz Ins. T. II, 

 71; Muls. et Fey Brevip. 1871, 158; Janglb. Kaf. M. II, 269. - Tharriaeonia 

 Thoms. Skand. Col. II, 278). 



From Leptusa , with which Suryusa agrees in structure of mouth-parts, 

 it is easily separated by the much broader and flatter shape of the body, 

 by a peculiarly broad pronotum, as oroad as or broader than elytra. These 

 inside §1* the outer hind corners are deeply incurved. First joint of hind 

 tarsi as long as the two following joints together. 



The species live principally in company with certain ants ( Lasius brun- 

 neus a nd nlj^er) . mostly in old hollow trees. Of the few Middle European 

 species none are heretofore found in Denmark, but a single one in Skaane. 

 This is here briefly described.
