 scattered and indistinct punctation, very densely shagreened, it6 side- 

 margins upwardly bent. L. 2-2.5 mm. (Fig. 182. Phloeonomus puslllus 3ravh.) 



In wooded regions, not rare in this country, most frequent under the 

 bark of pinacious trees, which are attacked by bark beetles, but also 

 unaer the bark of deciduous trees and stubs, and at outflowing tree sap. 

 - The larva lives in same places as the beetle and is (accd.to Janglb.) 

 described by Perris (Ann. Soc. Sntom. Fr. 1853, 578, Pi. 17, Fig. 56-5S). 



A form of pusillus Jrach. with more distinct and densely punctated 



elytra is by Thomson treated as a separate species: Ph. punctipennis Thorns. 



Skand. Qol. IX, 317. It occurs mostly under bark of infested deciduous 



trees, namely beech ana birch, it deviates not essentially from the typl-

 cal form. 



Closely related to Ph. pusillus iravh., but considerably larger, is 

 Ph. ( Xylodromus Thorns.) moailicornis Jyllh. It is blackish-brown, glis- 

 tening, scarcely haired, first five joints of antennae, mouth-parts, and 

 the legs reddish-yellow, margins of pronotum and humeri of elytra often 

 brownish. Distal joint of maxillary palpi is considerably thinner and 

 three times as long as the next-last, antennal club sharply set off, pro- 

 portionately long haired; pronotal longitudinal impressions flat, the head 

 with simple and pronotum with scattered, rather robust punctation, elytra 

 with more robust and rather dense punctation; abdomen almost smooth, its 

 side-margins strongly upturned. L. 3-3. t mm. (Janglb.). 



It is destributed in Middle Europe and is also found in Sweden and 

 Norway, under the bark of pinacious trees. In Denmark it is heretofore 

 not found.
