sparsely, irregularly clothed with long, erect and recumbent, whitish 

 hairs, sparsely granulose on basal half, the granules elongate on 

 median area, densely granulose and irregularly dentate on apical half, 

 the teeth broad, semierect, variable in size, and rasplike, especially on 

 top of disk, and with three to four larger tubercles on each side along 

 lateral margin. Scutellum triangular. 



Elytra at base subequal in width to pronotum at middle; sides 

 slightly expanded posteriorly, conjointly broadly rounded at apices; 

 submarginal carina following outline of lateral margin, sharply ele- 

 vated along apical declivity ; surface rather densely, irregularly clothed 

 with erect, arcuate, yellowish or whitish hairs, which are denser and 

 much longer toward sides, coarsely, densely, irregularly punctate, the 

 punctures somewhat finer near apices ; apical declivity arcuately de- 

 flexed, not margined anteriorly, each elytron with a costif orm tubercle 

 at top of declivity, and two smooth, erect tubercles placed transversely 

 at middle of declivity, the inner tubercle long, slightly divergent, acute 

 at apex, placed some distance from sutural margin, outer tubercle 

 short, obtuse at apex ; sutural margins not elevated on apical declivity. 



Body beneath finely, densely punctate, rather densely clothed with 

 long, recumbent and semierect, whitish hairs; last visible abdominal 

 sternite broadly rounded or subtruncate at apex. 



Length 3.5-6 mm., width 1.75-2.5 mm. 



Type locality. — Of sexdentatum, Provence, France ; present location 

 of type is unknown to writer. Of bidens, Tangier, Morocco ; type in 

 the Copenhagen Museum. 



Distribution. — This species is distributed throughout the greater 

 part of the Mediterranean region, both in Europe and Africa. Speci- 

 mens were intercepted at New York, October 20, 1941, and January 

 29, 1946, in wooden slats around bundles of cork from Portugal. So 

 far as known, this species has not become established in the United 

 States. 



Hosts. — The larvae of this species live in the dead and dying 

 branches of various nonconiferous trees, but in France and Italy pre- 

 fer the fig and grape. The species has also been recorded in mul- 

 berry, locust, olive, clematis, rose, ivy, chestnut, peach, pear, elm, 

 Quercus ilex, Acacia dealbata, Acacia eburnea, Paliurus aculeatus, 

 and Arwndo donax. 



Olivier (1790) described sexdentatum from specimens collected in 

 grape wood. Fabricius (1798) described bidens from Tangier. 

 Lesne (1901), on the basis of Meinert's comparison of a specimen 

 of sexdentatum Olivier with the type of bidens Fabricius in the Mu- 

 seum at Copenhagen, placed bidens Fabricius (1798) as a synonym 

 of sexdentatum Olivier (1790) .
