TENTHREDINID.E. DOSYTHEUS. 81 



Te. cingulata. Fabricius.—Steph. Catal. 337. No. 3927. 

 Black : antennse with the 2 basal joints pale rufous ; palpi pale ; whig scales 

 pale luteous ; abdomen rather pitchy, with all but the basal segment dis- 

 tinctly edged with pale yellow ; legs pale, with the base of the femora 

 black; that of the tibiee whitish-yellow^, and the tarsi dusky; wings 

 hyaline, slightly lutescent, the nervures, costa, and stigma yellowish, the 

 latter with a brownish tinge : in the second submarginal areolet is a dusky 

 dot, situated posteriorly. 



Extremely abundant within the metropolitan district, especially at 

 Coombe wood, in the beginning of June ; but, although I have 

 taken it in the last locality by hundreds, I have not seen the male, 

 which — so far as I can make out by his German account — appears to 

 be the case with Klug.
