with a wide yellowish band on dorsal margin of inner surface, and 

 base and apex yellowish on outer surface; pedicel brownish yellow 

 on outer side and blackish on inner surface; funiclo and club brown, 

 with the last two funicle joints slightly paler. Legs pale yellowish; 

 tibiae with two broad brown annuli at the base and near middle, 

 fainter and narrower on hind pair and still fainter on front pair; last 

 joint of the tarsi tipped with blackish. Wings hyaline, the veins 

 pale yellowish. 



Female. — Not known. 



Redescribed from eight males (six of them cotypes) reared from a 

 Pulvinaria on Rihes, Aumesville, Oregon, February 1-17, 1890 

 (F. S. Mattison). This species will presumably prove to be the male 

 sex of californicus Howard. 



Type.— Ctii. No. 5048, U.S.N.M. 



41. APHYCUS AMOENUS Howard. 

 Aphycus amoenus Howard, Joiirn. Linn. Soc. Loml., ZooL, vol. 26, 1896, p. 150. 



The type of this species was not accessible for study and no other 

 specimens were examined. Judging from the description it is 

 closely related to rusti described from Peru but considerably darker 

 in coloration. It was described from a single male collected at Bal- 

 thazar, Grenada (H. H. Smith). 



Type. — In the British Museum. 



42. APHYCUS IMMACULATUS Howard. 

 Aphycus immaculatm Howard, Insect Life, voL 6, 1894, p. 236, fig. 11. 



The type, a single male mounted on a slide, was not found in the 

 United States National Museum, and no other specimens are known. 

 The species is apparently similar to alberti Howard but distinct, 

 judging from the description and figure. It was supposed to have 

 been reared from Clirysomphalus aurantii (Maskcll),but if it is a true 

 ApTiycus, the record is undoubtedly erroneous. 



Type.— Cat. No. 1474, U.S.N.M. 



43. APHYCUS HOWARDI Cockerell. 



Aphycus howardi Cockerell, Can. Ent., vol. 30, 1898, p. 276. 



The single type specimen of this species in the United States 

 National Museum is so badly damaged that its relationship with the 

 other species considered in this paper could not be determined, and 

 it consequently was not included in the synoptic table. It should, 

 however, be easily recognized by its bright scarlet coloration, wliich 

 is unique. It was reared from Eriococcus tinsleyi Cockerell at 

 Mesilla Park, New Mexico.
