228 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.45. 



Body, excluding appendages, brown, marked with a broad band of ivory white between 



wings and across ventral half of face rhizococci group. 



Body, excluding appendages, mostly brown or black brown, marked with orange or 



lemon yellow, the brown predominating flavopalliata group. 



Body, excluding appendages, uniformly brown, the abdomen marked with brown 



black, marginal cilia long maculata group. 



Body, excluding appendages, mostly lemon or orange yellow, marked with brown or 



brown-black, the yellow predominating aleyrodis group. 



I. nigra group. 



This group includes the following species which are all uniformly black, or black 

 tinged with metallic greenish, or black suffused slightly with brownish: nigra Ash- 

 mead, australiensis Ashmead, dactylopii Ashmead, noacki Ashmead, pulchra Girault, 

 maxima Girault, funeralis Girault, corvina Girault, australica Girault, and nigrella 

 Girault. The species may be identified by the use of the following table: 



Marginal cilia of the fore wing at extreme apex short, distinctly much shorter than a 

 third of the greatest width of the fore wing; stigmal vein at inner edge nearly 

 in a straight line with the marginal vein, or making only a slight acute angle. 



Posterior wings broad 1. 



Marginal cilia of the fore wing at extreme apex moderately long, twice longer than in 

 the first group and distinctly as long as or longer than a third of the greatest 

 width of the fore wing; inner margin of stigmal vein forming a more or less 

 distinct curve with the inner margin of the marginal vein at apex or making an 



obtuse angle. Posterior wings variable, often moderately narrow 2. 



1. Apical half of the fore wing not clouded or but slightly so, not smoky like the 



proximal portions. 



Proximal third of fore wing smoky, the smoky area not reaching to the end of the 



marginal vein but ending about the length of the stigmal vein distant from it; 



distal third of fore wing sometimes slightly clouded; body black. Marginal 



cilia at apex of fore wing longer, distinctly longer than the stigmal vein. 



nigra Ashmead. 

 Fore wings fumated not quite out to the end of the stigmal vein but the distal 

 margin of the fumation is obliquely truncate, caudo-proximad and the caudal 

 half of the wing under the venation is nearly hyaline; body marked with 

 metallic green ; marginal cilia at apex of fore wing very short . . . corvina Girault. 

 Fore wings with a somewhat irregular, clear-cut, moderately broad smoky band 

 across it from the marginal vein, the band narrowed at its middle; otherwise 

 hyaline. Body black, marked with metallic green on the vertex and mesono- 

 tum. Marginal cilia at apex of fore wing subequal in length to stigmal 



vein dactylopii Ashmead . 



Nearly all of the apical portion of the fore wing (nearly a half), except perhaps 

 at extreme apical margin, clouded nearly as deeply as proximal portions. 

 Fore wings entirely smoky excepting at extreme apical margin and conspic- 

 uously near the middle where a moderately broad elliptical subhyaline band 

 crosses from the apex of the venation (excluding the usual clear spot more 

 proximad, near caudal margin); this band is widest at the middle, its edges 

 irregular. Body black, the vertex and mesonotum metallic green. Mar- 

 ginal cilia at apex of fore wing distinctly longer than stigmal vein but vari- 

 able, sometimes no longer than the stigmal vein or somewhat shorter. 



australiensis Ashmead. 



Fore wings fumated throughout, nearly uniformly but the fumation is deeper 



proximad. Marginal cilia at apex of fore wing nearly twice longer than the 



stigmal vein funeralis Girault.
