Redescribed from the following material: One female, Jackson- 

 ville, Florida (W. H. Ashmead) ; one female reared from ToumeyeUa 

 liriodendri (Gmelin), Crescent City, Florida, March 18, 1895 (H. G. 

 Hubbard); one female from the same host, Molino, Florida, May 25, 

 1894 (S. S. Harvey); four males from same host, Laurel, Maryland, 

 June 11, 1912 (E. R. Sasscer); two females, five males reared from 

 Tacliardia on Acacia, San Diego, Texas, July 12, 1896 (E. A. Schwarz) ; 

 one female, one male reared from Tacliardia species on "Huajillo" 

 with no locality given; three females, one male reared from Pulvinaria 

 pyriformis Cockerell, Port-of-Spain, Trinidad (P. Lachmere-Guppy) ; 

 one female reared from Coccus liesperidum Linnaeus, Lima, Peru, 

 December 21, 1909 (C. H. T. Townsend), Townsend No. 140° 3a; a 

 large series of both sexes reared from Pulvinaria species on sweet 

 potato, Sullana, Piura, Peru, during February and March, 1912 (E. W. 

 Rust), received from Messrs. Townsend and Rust under No. 35° 3a; 

 one female, one male reared from Saissetia oleae (Bernard), Palermo, 

 Sicily, received from H. S. vSmith under California State Insectary 

 No. 7205 and d. 



The type female of this species from Palatka, Florida, could not 

 be found. It was supposed to have been reared from Lepidosaplies 

 hecTcii (Newman), but the record is undoubtedly erroneous. 



There are slight but apparently constant difi^erences in coloration 

 in material from different locahties which are probal)ly due to local 

 variation and not of specific value. The females from Trinidad 

 have the face, cheeks, underparts of thorax, and the abdomen bril- 

 liant chrome lemon without dark markings on the concealed part of 

 the occiput and pronotum. The material from Peru varies from 

 bright orange to a little paler and there is a small transverse blackish 

 spot on the concealed part of the pronotum. The males also difl'er 

 in having but a slight brownish infuscation in the center of the 

 dorsum of abdomen.
