ANNALS OF The Entomological Society of America Volume 1 SEPTEMBER, 1908 Number 3 A MONOGRAPHIC CATALC^QE OF THE MYMARID GENUS ALAPTUS HALIDAY, WITH DESCRIPTIONS OF THREE NEW NORTH AMERICAN FORMS AND OF ALAPTUS ICERYAE RILEY FROM TYPE MATERIAL. By a. ArsiJne Girault, Office State Entomologist, Urbana, 111. INTRODUCTION. This paper is a catalogue monographic in nature, pureh' from the fact that as the species of the genus are listed, the ori-ginal descriptions are quoted; it is not a monograph, as the types of most of the species have been inaccessible. Neither is the history of the genus touched upon to any extent on account of the lack of literature. Simply as a matter of convenience, the original descriptions of the species are given with the descriptions of the three new species here included, so that the descriptions of all the species of the genus are brought together. A pre-liminary bibliography of the species is also given, but it may be stated that the literature of the group is most fragmentary. The forms in this genus are so minute and delicate, and their preservation so difficult, that it is not surprising that the types have in the main been lost, or no attempt made to keep them. The similarity of the various species in structure and color makes this most unfortunate, especially as most of the original descriptions are very inadequate. I have found that antennal structures afford the best specific characters, and these have in the main, received no attention from former systematic workers in this group. Some of the descriptions mean nothing at all. and on this account, it is a question whether the species described can be again recognized. 179
