The insect was originally described from Porto Rico as a Lithosiid, 

 and listed by Kirby as a member of that (sub) family. Hampson lists 

 it as a ''Noctuid" ("Acronyctinae") because vein 8 of the hind wing 

 anastomoses with the cell near the base only. 



The venation shown by Hampson is incorrect in that the pri- 

 maries possess an accessory cell. According to his keys the insect 

 would fall to Rhosus^; but the present genus is abundantly distinct, 

 vein 8 of the secondaries being approximated to the cell to about the 

 middle, showing an apparently close relationship to the Lithosiinac; 

 whereas RJiosus shows a decided relationship to the Agaristidae. Wing 

 shape, habitus, antennae, and other venational differences seem to 

 point to the conclusion that Cephalospargeta is a unique genus, with 

 no described close relatives in the Apatelinae (=Acronyctinae) ; and 

 which, possibly, may be placed in the Lithosiinae. 



PSEUDACONTIA MODESTELLA B. & McD. 



1917, B. & McD., Contr. N. H. Lep. N. A., IV, (2), 110, pi. XVI, f. 13, 



Pseudacontia. 

 1922, Dyar, Ins. Insc. Menst, X, 11, cephalica, Pseudacontia. 



Dr. Dyar sunk modestella as a synonym of {Stylopoda) cephalica 

 as noted above. Specimens compared with the type of cephalica prior 

 and subsequent to Dyar's paper show modestella to be a distinct species 

 rather closely related to groteana; and not at all closely related to 

 cephalica which is a member of the Cuciilliinae as stated on a prior 

 page. 



Pseudacontia sexpunctata B. & McD. 



1916, B. & McD., Contr. N. H. Lep. N. A., Ill, (1), 14, pi. Ill, f. 17, 

 Copanarta. 



The placement of Copanarta in the Cuculliinae would apparently 

 leave sexpunctata without an available generic name. 



As there is only a very slight difference in the claws on the fore 

 tibiae, this species may well be placed in Pseudacontia. 



zMystrocephala (type quadrimacula, synonym of postica) according to the present In- 

 ternational Rules apparently takes priority over Rhosus (type posticus).
