214 PROCEEDINGS OF THE NATIONAL 3IU8EUM. vol.45. 



fore mngs fiiscated nearly to tip but the fuscation is pronounced and 

 conspicuous only under the venation or but slightly distad of it; 

 caudal wings nearly hyaline; proximal portion of fore wing clearer 

 or wholly clear; structurally, nearly as in Jlavopalliata from wliich 

 I am hardly able to distinguish it; the stigmal vein, however, is longer 

 as is also the proximal joint of the cephalic tarsi and the body is more 

 robust. The discal bristle of the fore wing is absent and the antennal 

 club is long and clavate, the pedicel long-obconic, four times longer 

 than its width at apex. 



Male.— Unknown. 



Described from a single female specimen in the collections of the 

 National Bureau of Entomology, mounted on a balsam slide and 

 labeled "C. H. T., Lima, Peru. 192° 3a. Nov. Gen. 2nd sp. 1. 

 Dec. 31, 09. T." (Type.) Also another mounted on a slide with 

 S. aleyrodis and bearing the label "Asp. camellix on Acacia sp. 

 Mexico. From A. L. Herrara, Dec. 15, 1905." (U. S. Department 

 of Agriculture. Homotype, female.) 



Habitat. — Peru (Lima); Mexico. 



Host. — Aspidiotus camellise Signoret on Acacia in Mexico (homo- 

 type). 



Type. — Cat. No. 14195, U.S.N.M., one female in balsam. 



Homotype. — ^Accession No. 45096, Illinois State Laboratory of 

 Natural History, Urbana, 1 female on a slide with a male of S. aleyrodis 

 (Mexico). 



15. SIGNIPHORA. FLAVELLA, new species. 



Normal position. 



Female. — ^Length, 0.48 mm., mean. Small in size. 



General color as in jlava but the abdomen suffused with orange, 

 especially along each side of the middle; differs from. Jlava as follows: 

 The stigmal vein forms a less regular and shorter concave curve, along 

 its inner margin, with the apex of the inner margin of the marginal 

 vein, but it is convex instead of concave at its point of origin. The 

 fore mngs are distinctly narrower but with the marginal cilia as long 

 in proportion (long, graceful, distinctly longer than the greatest width 

 of the wing). Otherwise the same in all visible details, except the 

 wings, which are nearly similarly embrowned, but less deeply; also 

 the antennal club is dusky at tip or distal fifth instead of being wholly 

 dusky. The pedicel of the antenna is noticeably shorter and stouter, 

 while the antennal club is noticeably shorter. 



Male. — Unknown. 



Described from four female specimens mounted on a slide with S. 

 basilica, new species ^ and from the collections of the National Bureau 

 of Entomology (U. S. Department of Agriculture). The shde bore 

 tlie label " Signipliora. Aspidiotus latanise. Sapodella. Ochras 



' Described next.
