1. ACEROPHAGUS COCCOIS Smith. 



Acerophagus coccois Smith, North Amer. Entom., vol. 1, 1880, p. 84, figs. 20-23. 

 Rhopus coccois Howard, Rept. Coram. Agric. for 1880, 1881, p. 361, pi. 24, fig. 2. 

 Metallon coccois Ashmead, Proc. U. S. Nat. Mus., vol. 22, 1900, p. 407. 



Female. — Front and vertex about twice as long as wide; ocelli in 

 rather an acute-angled triangle. Antennal scape short and flattened ; 

 pedicel nearly as long as the funicle joints combined; the latter all 

 short, wider than long, subequal in length, and increasing in width, 

 the fifth nearly twice as wide as the first; club large, oval, rather 

 pointed at apex, and as long as funicle and pedicel combined. Wings 

 uniformly ciliated, the oblique hairless streak narrowed above and 

 separated below from the posterior border of the wing by only one 

 row of cilia. Ovipositor not protruded. Length, 0.6 mm. 



Notum of thorax and abdomen orange yellow, head chrome lemon 

 yellow, under side of thorax, the antennae, and legs pale yellowish. 

 Wings hyaline, the veins nearly colorless. 



Redescribed from one female reared from Phenacoccus acei'icola 

 King, July 20, 1898, Springfield, Massachusetts (R. A. Cooley), appar- 

 ently correctly identified. The head and antennae are much shriv- 

 eled so that the above description may not be fully accurate in all 

 details. The location of Miss Emily Smith's types is not known, if 

 indeed they are still in existence.

F(PTOaZ^.— Front and vertex about three-fourths longer again than 

 wide, narrowest near the middle; ocelli in a little less than a right- 

 angled triangle, the posterior pair not quite their own diameter from 

 the eye margin and nearly twice their diameter from the occipital 

 rim, the front ocellus at the center of the front and vertex; face as 

 long as the length of the eyes, the scrobes deep and prominent, gradu- 

 ally converging and uniting above; eyes about one-fourth longer than 

 wide, covered with a thick but very short, fine pubescence. Antennal 

 scape slender, slightly thicker at the middle, hardly extending beyond 

 the plane of front; pedicel a little longer than the first three funicle 

 joints combined; funicle joints subequal in length, the first as long as 

 wide, the following increasingly transverse, the fifth being twice as 

 wide as the first; club thicker near base, gradually tapering to a 

 slightly rounded apex, one-third wider again than the last funicle 

 joint, and as long as the funicle and one-half the pedicel combined. 

 Wings uniformly ciliated ; oblique hairless streak widened below and 

 narrowly separated from the posterior margin of wing. Ovipositor 

 protruded about one-fourth the length of the abdomen, exserted por- 

 tion covered with long pubescence. The pubescence of head and
