Page:The Gall Wasp Genus Cynips.pdf/184

 Die Wespe bewohnt eine Blattgalle auf Quercus pubescens, und ist eine Entdeckung des Herrn Kollar in der Umgegend Wiens. Die Galle sitzt, wie alle Blattgallen auf der Unterseite des Blattes einer Blattrippe auf und besteht aus einem glatten, harten, drei Linien langen und ½-¾ Linien dicken, in der Mitte verengten, an der Spitze keulenförmig etwas erweiterten, mitunter etwas gekrümmten Hörnchen.

Translation. Cynips carnifex Kollar: black, with the mesonotum spotted black and the legs rufous; the coxae and the posterior tarsi black; length 2 mm.

The wasp lives in a leaf gall on Quercus pubescens, being a discovery of Kollar's in the neighborhood of Vienna. Like all leaf galls on the underside of the leaf, the gall is attached to a leaf vein; it is a smooth and hard horn, 6 mm. long and 1 to 1.5 mm. in diameter, constricted in the middle, with the tip club-shaped but somewhat swollen, the gall sometimes crumpled.

The beautiful, slender, conical, green or reddish-brown gall of this species is a unique departure from the more or less strictly spherical galls of the other species of European Cynips. Internally the gall shows some of the compact, spongy fibers which occur in the galls of nearly all species of
