12 INSECUTOR INSCITI/E MENSTRUUS 



from the United States was therefore not this species, unless their mate- 

 rial has disappeared from the collection. I do not know what it was, but 

 imagine that the Brazilian dodorium (called derogata = luridula) had 

 been in the collection so long that it was supposed they must be North 

 American. 



Anomis doctorium Dyar. 



I have no specimens from the United States, though, as it occurs in 

 Barbados and Cuba, its occurrence here would not be unlikely. The 

 record of luridula Gn. from the United States, noted above, may be 

 based on this species, though I think not ; I think that to be simply a con- 

 fusion of mind. This species is evidently not migratory, though very 

 abundant locally on cotton. Koebele collected by far more of this spe- 

 cies in Brazil in I 883 on cotton than any other.* The larvae preserved 

 by him resemble those of texana rather closely. They are mostly heavily 

 marked, the dorsum nearly solidly vinous black, the tubercles small, black, 

 as in texana. Some lightly marked forms occur and even nearly immac- 

 ulate green ones, although I cannot tell whether these may not be larvae 

 of erosa, which Koebele also took, as names of food plants are not 

 attached. The structure of the feet does not separate these. The differ- 

 ently colored larvae are numbered differently and perhaps the puzzle is 

 capable of solution by sufficient research in old files. It does not seem to 

 me worth the trouble in the present connection. 



* Koebele collected long series of other species in the Brazilian cotton fields. The 

 migratory cotton moth, Alabama argillacea, seems to have been present in only small 

 numbers, and Koebele preserved no specimens of its larva among the series of inflated 

 specimens. Our familiar Laphygma fmgiperda S. & A. was there, Xylomyges sunia 

 Guen^e in some numbers, a few X. eridania Cramer, but especially abundant were 

 Perigea concisa Walker, P. sutor Guenee, and Bagisara subusta Hubner. It would 

 seem as if, provided all these insects were feeding on the cotton, that there should not 

 have been a leaf left in those Brazilian cotton fields. The circumstances are partly 

 explained in the report of J. C. Branner, published as Appendix V to the 4th Rept. 

 U. S. Entomological Commission. It is stated that Koebele caught the moths from 

 flowers that grew about the house where he stayed. Only a small proportion were 

 cotton moths. The investigations at Bonito extended over January and February. 

 January 8 eggs and larvas of doctorium were found and the first moth issued January 

 23. No argillacea appeared until February 6. This species is therefore later in appear- 

 ance than doctorium and may have been abundant enough afterwards.
