Howard, 1881, p. 368. Ashmead, 1900, p. 345. 
Ashmead records Moranila testaceipes Cameron described from Oahu, Hawaii as a synonym 
of this species; also that there is a specimen of this species in the collections of the United 
States National Museum, Washington, D.C., from Australia. The species is an associate of 
commercial crops. 
Habitat: North America (California). Sandwich Islands. Australia. 
Host: Lecanium olece 
Type: Probably in the United States National Museum, Washington, D.C., U.S.A. 
Genus OPIIELOSIA Riley. 
Riley, 1890, p. 249. 
“ Closely resembles in habitus Dilopliog aster Howard (see Ann. Rept. Dept. Agr., 1880, 
p. 368, where it is described as Tomocera, subsequently changed to Dilophog aster on account 
of the preoccupation of Tomocera in Thysamtra ) T with which it agrees in many characters, 
but from which it is sharply defined. The antennal peculiarities are identical in the two forms, 
viz.: The simple, clavate, 10-jointed female antenna), and the compressed, serrate, hairy, 
9-jointed male form. The wings in Ophelosia differ markedly, as follows: The sub-marginal 
vein is not curved downward; the marginal is more than twice as long as the stigmal; just 
below the bend of the sub-marginal in the female is a broad patch of very stout bristles arising 
from the wing surface. The petiole of the abdomen is nearly as long as the width of the 
metascutum; the fimbria) of the callus are very dense, but short. The tufts of hair at base 
of abdomen are sparse. The hind tibiae are furnished at tip with a long, slender, slightly- 
curved spine, nearly as long as the first tarsal joint, while in Dilopliog aster it is entirely 
unarmed. ’ ’
