Volume 6 includes three contributions:
Le genre Eacles en Guyane française (Lepidoptera: Saturnniidae; Caratocampinae) (Marc Metzger):
On the basis of 11 years of field survey and the examination of French private and public collections (including MNHN of Paris and Musée des Confluences of Lyon), the author concludes that Eacles Hübner, 1819 comprises 8 species in Guiana. All of them are described and illustrated (imagines and caterpillars, obtained by rearing), with the distribution maps in French Guiana, the flight times and seasons and the description of various outstanding specimens.
Les Castniidae de Guyane française (Lepidoptera: Castnioidea) (Frédéric Bénéluz et Jean-Yves Gallard):
Knowledge on French Guiana's Castniidae is reported by the authors. Taxonomy, biology and behaviour of the family are studied in this paper. Eupalamides preissi and Oiticicastnia erycina are reported there for the first time. Confusion in literature between Eupalamides guyanensis and E. cyparissias is discussed.
Le Genre Letis Hübner,  sensu lato en Guyane française (Lepidoptera: Erebidae; Erebinae) (Jérôme Barbut, Jean-Marc Iurretigh & Bernard Lalanne-Cassou):
An annotated list of the genus Letis Hübner,  sensu lato present in French Guiana is given. The habitus and male and female genitalia of each species are illustrated.
