摘　　要：Two new species of lacewings are described and illustrated from the Jiulongshan Formation （Middle Jurassic） of Inner Mongolia, China： Leptolingia calonervis sp. nov. and Litholingia ptesa sp.nov. （Grammolingiidae）. The species can be distinguished by the following features： the outermost branch of MP2 on the hind wing did not reach the margin of wing in Leptolingia calonervis sp. nov.;the second branch of Rs forked deeply while other branches of Rs forked much later in Litholingia ptesa sp. nov..Two new species of lacewings are described and illustrated from the Jiulongshan Formation （Middle Jurassic） of Inner Mongolia, China： Leptolingia calonervis sp. nov. and Litholingia ptesa sp.nov. （Grammolingiidae）.
