4. MIMETIC RESEMBLEMCES BETWEEN DIPTERA AND HYMENOPTERA. BARON OSTEK-SACKEN exhibited a number of specimens of Diptera and Hymenoptera to illustrate the mimicry which obtains in certain cases. The instances selected were Laphria and Bombus ; ~,~stro~~& and Ammo- phila ; Ceria and Ancistrocera ; Ceria and Polistes ; Ceria and Conops (both Diptera); Spilomyia and Vespa, He further remarked that there is a great resemblance between Hispa suturalis and Capsus roliniae, a beetle and a bug frequenting the leaves of the locust-tree, (Mar. 13, 1874.) , 5. CAPTURE OF RARE PSEUDONEUROPTERA AND NEU- ROPTERA. I&. HAGEN said that many rare species of Pseu- doneuroptera and Neuroptera had been collected this year, some by himself in Massachusetts, and some by Mr. Sanborn in Kentucky. Amongst these are Calopteryx angustipennis and Petalum Thoreyi. The two other species of Petalura known belong to New Holland. This genus is so exceptional that the first specimen of the American species was declared by Selys to be of necessity Australian and erroneously labelled. Some larvae from the same locality and collector probably belong to Petalura. By the dilated antennae they agree, with the larva of Hagenius. Two Aeschna furcillata were cai~glit in Manchester, Mass. Only one specimen is known to exist in Europe. A specimen of Neuronia pardalis was also captured. The only nearly related species live in Japan, the northern part of Europe and in Siberia. They have the peculiarity to fly very high ; this specimen was taken on top of a stage-coach. Dr. Hagen farther obtained a Hemerobid of the genus Dila from Kentucky : the male with pectinated antennas, the female with a long ovipositor like that of Rhaphidia. Two species are known from Europe and two from Asia, viz: one from Ceylon and one from India. (Oct. 9, 1874.)
No. 15 was issued July 7, 1875.
