40 INSECUTOR INSCITI/E MENSTRUUS 



reticulations. Researches should be made in Georgia to see if this form 

 really exists there. Boisduval says that the larva is rather common in the 

 interior of the branches of Phaseolus.^ 



Dysodia summargo, new species. 



Ground color suffused with coppery brown, shining yellowish toward 

 bases of wings and costa ; reticulations dense, purple-brown, tending to 

 circles with central dots ; bands broad, even, subpar^lel, with dentate 

 edges, the basal two a little curved, the outer and 'submarginal nearly 

 straight ; margin of wings well scalloped ; fore wing with narrow oblique 

 white-hyaline discal spot. Hind wing with large constricted spot ; costa 

 and tornus dark shaded ; reticulations distinctly circular. Expanse, 25-30 

 mm. 



Cotypes, 13 specimens, No. 15531, U. S. Nat. Mus. ; Jalapa, Mex- 

 ico (Schaus collection) ; Cordoba, Mexico, May, 1 906 (W. Schaus) ; 

 Orizaba, Mexico, March, 1908 (R. Muller). 



Dysodia immargo, new species. 



Ground color coppery brown ; pale yellow very narrowly on costa ; 

 reticulations very fine and dense, the pale intervals tending to be puncti- 

 form ; bands broad, similar, but little relieved, the submarginal shading to 

 the margin ; discal spot of fore wing small, of hind wing constricted, 

 white-hyaline. Hind wing nearly uniformly purplish reticulate, with 

 punctiform intervals of ground color. Expanse, 2 1 mm. 



Type, No. 15532, U. S. Nat. Mus.; Cordoba, Mexico, May, 1906 

 (W. Schaus). 



Dysodia granulata Neumoegen. 



Platythyris granulata Neumoegen, Papilio, iii, 137, 1883. 

 Described from Arizona. The species is not before me, but seems 

 well characterized by Neumoegen. 



Dysodia monava Dyar. 



Dysodia monava Dyar, Proc. U. S. Nat. Mus., xliv, 317, 1913. 

 This species has the ground color yellow, the margins broadly dark 

 shaded ; the submarginal line is very narrow. Only the type from Mex- 

 ico is before me. 



' Possibly this is an earlier name for Thyris maculata Harris. The habit of the 

 larva as an internal feeder in stems would suggest Th\)ris. The larvae of Dysodia live 

 in rolled leaves. But I cannot reconcile Boisduval's figure with maculata.
