XXVIII. ANNA1.ES MUSEI NATTONALIS HUNGARICI. 1934. THE HYDROMETKIDAE OF THE HUNGARIAN NATIONAL MUSEUM AND OTHER STUDIES IN THE FAMILY. (HEMIPTERA). (WITH PLATES I— XII). By H. B. HUNGERFORD and N. E. EVANS University of Kansas, Lawrence, Kansas Through the kindness of Dr. GEZA HORVATH the senior author was permitted to spend some time at the Hungarian National Museum in Budapest in the year 1928. Here he found an interesting collection of Hydrometra containing several undescribed species. Although Dr. LIORVATH had recognized some of the species as new and had assigned mannscript names to them he most generously surrendered them for further study and they were brought to Kansas where they have served as the basis of this study. Other unidentified specimens, assembled by the senior author, from varions museums have been examined and are reported as a part of this paper. Occasion is also taken to report notes concerning types that have been viewed by the senior author. Besides examining the coliections in a number of European Museums and some of the more extensive ones in America, we have had for study 1669 specimens from the University of Kansas Entomological Museum. The old world collections should. be more extensive than they appear to be at present and should be examined intensively by one who has accumulated long series. It seems quite probable that more species occur there. There are, without doubt, many undescribed species of this curious genus yet to be collected. It is hoped that the plates of drawings and the synoptic keys to the Hydrometra of both Hemispheres may prove useful to future students of this family. We have accepted the synonomy of OSHANIN in his ,,Katalog der palaarktischen Hemipteren" 1912 for Hydrometra stagnorum. L. and recognize as Hydrometra stagnorum L. European specimens determined as such by Dr. HORVATH since the type is unknown to us. We cannot, however, recognise the synonomy
