. The Australian zoologist. Zoology; Zoology; Zoology. TILLYARD AND FRASER. 205 alone would place the genus in the Megapodagriidae. It will be noticed that Dr. Tillyard has placed the two genera Dysagrion Scudd., and Phena- colestes Cock., in the Megapodagriidae, but in both these, the postnodals fail to coincide with the cross-veins behind them, a character which carries them forward to the Amphipterygidae. Dysagrion, Phenacolestes, Petro- lestes, Philoqanga and Diphleoia form an instructive series demonstrating the gradual recession of the origins of Riv + v and Fig. 5.—Chlorocyphida

Dysagrion, Phenacolestes, Petro- lestes, Philoqanga and Diphleoia form an instructive series demonstrating the gradual recession of the origins of Riv + v and Fig. 5.—Chlorocyphidae:—1.—Chlorcypha Fraser (Ethiopian). (Note the anterior arching of Rii + iii). 2.—Libellago Selys (Oriental). (Note the absence of the anterior arching of Rii + iii in this primitive genus). 3.—Rhinocypha tincta Rambur (Australia). (Rii + iii markedly arched.). Family 2. Chlorocyphidae Cowley. (Fig. 5, 1 to 3.) Wings subpetiolate, narrow and similar in shape in the females, narrow or more or less dilated medially, especially the hindwing, in the males. The primary antenodals always present, as well as numerous secondaries, varying from five to twenty. Nodus situated between one-third and half- way along the costa; discoidal cell an elongate rectangle, always traversed; pterostigma narrow, elongate and strongly chitinized. Rii + iii, shortly after leaving Rs, straight in primitive genera, but distinctly arched.
