Agnew Department of Entomology, Texas A&M University, College Station, Texas 77843-2475. Abstract. —Acigona Hubner has been incorrectly used as a generic name in the Cram-binae due to an earlier type designation of a noctuid species. Acigona (sensu Bleszynski) is composed of genus level taxa which should not be considered congeneric. Friedlanderia n. name is proposed as a replacement name for Chiloides Bleszynski 1963, a homonym of Chiloides Butler 1881. The type, Tinea cicatricella Hubner, had been incorrectly des-ignated the type of Acigona by Bleszynski. Eoreuma morbidella (Dyar) n. comb, and Coniesta forsteri (Bleszynski) n. comb, are transferred from Acigona. Some unfortunate taxonomic errors have resulted in much confusion regarding the use of the generic name Acigona within the subfamily Crambinae (Lepidoptera: Pyral-idae). The incorrect usage of this name for crambine species is especially widespread in the non-systematic literature as the larvae of several species have been reported to in-fest agronomically-important Poaceae. Al-though many of the problems cannot be remedied until a revision o{ Acigona (sensu Bleszynski, 1967) is completed, some con-tributions toward nomenclatural stability can be made at this time. The genus Acigona was proposed by Hub-ner ([1826]: 342) for two species without a type species being designated. Hampson ( 1 926) selected one of these, Phalaena man-to Cramer (Noctuidae), as the type of Aci-gona and treated the genus as a synonym of Euclystis Hubner. Bleszynski and Collins (1962), apparently unaware of this action, designated the other included species. Tinea cicatricella Hubner (Pyralidae) as the type of Acigona in the Crambinae. Bleszynski (1963) also designated T. cicatricella as the Xy^to{ Chiloides \mst\ 1949. Amsel(1949) originally included two species, T. cicatri-cella and Chilo hederalis Amsel in Chi-loides. Bleszynski (1963) decided Amsel had not properly designated a type species as required by The International Code of Zoo-logical Nomenclature (Article, 1 3b), which made the generic name unavailable. Al-though Amsel appeared to indicate T. ci-catricella was to be the type, the wording is somewhat ambiguous and probably fails to satisfy the Code. In either case, Bleszynski intended Chiloides to become a junior ob-jective synonym o^ Acigona. Bleszynski (1965, 1967) expanded his concept o{ Acigona to encompass species of the genera Coniesta Hampson, Eoreuma Ely, Haimbachia Dyar, Achilo Amsel, Do-nacoscaptes Zeller, Girdhiara Kapur and Xubida Schaus, all of which share a con-dition of the female genitalia where a nar-rowed extension or "bridge" from the an-terior margin of the eighth tergite extends down onto the ostium bursa. Bleszynski (1967) also transferred several species to Acigona from Chilo, Erupa, and Eufernal-
