Synnologa tliriophora, n. sp. 



S 2 • 10-14 mm. Head whitish-grey or whitish. I'alpi dark 

 grey, sprinkled whitish, second joint with some lateral bristles. 

 Maxillary palpi short, slender, porrected. Thorax whitish, a trans- 

 verse anterior bar of dark grey irroration. Abdomen light grey,

 gently arched, apex obtuse, termen very obliquely rounded; 7 and 

 8 usually stalked; grey-wliitish, some scattered dark grey scales; 

 markings dark grey, partially or wholly suffused black ; a spot on 

 costa near base, whence a slender slreak runs to base of dorsum; 

 rather large rounded-triangular spots on costa at i and 3, and a 

 rather smaller one at | ; a transverse spot from middle of dorsum ; 

 a rather large irregular spot in disc at f ; three small spots forming 

 a rather curved transverse prgeapical series: cilia grey- whitish. 

 Hindwings light grey ; cilia whitish-grey. 



Eritxsh Guiana, Mallali, March (Parish) ; eleven specimens. 

 Possibly in this genus the missing vein of forewings is really 11, 

 the vein rising from middle of cell being 10; I am unable to 

 determine this preciselj^ but the characteristic position of these 

 veins is alike in all the species. Other characters show some 

 variation ; short maxillary palpi are usually present, and veins 7 

 and 8 of forewings are usually but not always stalked.
