and elevated and the abdomen raised, or to respond with reflex immobilization 

 (Blest, 1957). Specimens were reported by Blest to have been rejected by Cebus 

 monkeys.

GLAUCOSTOLA Hampson 



Glaucostola Hampson, 1901 : 87. Type-species: Leucopsumis guttipalpis Walker, 1856 : 1649, 



by original designation. 

 Glaucostola Hampson; Strand, 191 9 : 37. 

 Glaucostola Hampson; Seitz, 1920 : 329. 



The nominal species subtussignata is simultaneously here transferred from Auto- 

 molis and synonymized with Glaucostola flavida. There is a little doubt, however, 

 that flavida is not congeneric with the type-species of Glaucostola and that its 

 taxonomic placement needs to be investigated. 



Four species of this genus were studied by Blest (1964). All reacted to tactile 

 stimuli with 'reflex immobilization' (Blest, 1957). Three of these species had a 

 medium threshold of sound production. Glaucostola flavida was rejected by Cebus 

 monkeys. 



Glaucostola flavida Schaus 



Glaucostola flavida Schaus, 1905 : 221, pis 47 (type), i56e-g (genitalia). Holotype $, French 



Guiana: St Laurent, Maroni River (USNM) [examined]. 

 Glaucostola flavida Schaus; Seitz, 1920 : 330 [no figure]. 

 Automolis subtussignata Bryk, 1953 : 215. Holotype 9. Brazil: Amazonas, Rio Purus (NR)

The unusual many-grooved tymbal organ of this species is shown on PI. 34. 



GORGONIDIA Dyar 



Gorgonidia Dyar, 1898a : 36. Type-species: Zatrephes garleppi Druce, 1898a : 148, by 



subsequent designation of Hampson, 1901 : 39.

 Gorgonidia Dyar; Watson, 1971 : 5. [Re-establishment of genus.] 



Gorgonidia garleppi, one of the two species dealt with here, was transferred to 

 Automolis by Watson (1971 : 5, 60) but is included here so that the associated 

 subspecies names can be dealt with.
