men, while the specimens which I have show considerable colorational 
variation. * 
The appearance of this parasite upon the destructive mealy bug is to 
be welcomed. <A large colony of the latter insect was completely de- 
stroyed by this Leptomastix and the Chiloneurus just mentioned. It is 
possible that both are recent introductions; at all events, neither has 
ever been bred from Dactylopius here before, and we shall watch for 
them another season with interest. 
Subfamily APHELININE. 
The two genera mentioned under this subfamily may be separated as 
follows:

IB MHOLe myn e Sawlbh morsuCh wine ieee eae sae ee ee ee ee COCCOPHAGUS. 
Genus COCCOPHAGUS: Westwood. 
Antenne 8-jointed; scape rather short and stout; pedicel one-third the length of 
scape and of about the same thickness; joints 3, 4, and 5 increase very slightly or 
not at all in thickness and decrease in length; club very plainly 3-jointed, a little 
longer than the preceding two joints. Mesoscutum large, its posterior broader, with 
a slight re-entering angle; sutures between parapsides and scapule very oblique. 
Mesoscutellum nearly as long as broad, rounded behind, the fore part forming three 
sides of a hexagon, the side bordering on the scutum a little shorter than the other 
two; wings equally hairy, except at base; no hairless line. Stigma small, but plainly 
visible, subtriangular in form. Middle tibial spur usually not as long as first tarsal 
joint, often curved. Species usually of somber colors, often of two contrasting colors, 
black and yellow. 
37. (1) Coccophagus vividus, n. sp. 
Female.—Lenegth, 1.03™™; wing expanse, 1.96™™"; greatest width of fore wing, 
0.35™™, General color shiny black; antenne light brown, with the customary dark 
brown longitudinal carine ; greater part of mesoscutellum and visible portion of me- 
tascutellum bright orange-yellow, the line of juncture of the two colors on the meso- 
scutellum slightly irregular but not curved; tegule yellow; all coxie and femora 
brown, yellow at joints; all tibe and tarsi yellow, occasionally a dusky patch near 
base of hind tibe, and the fifth tarsal joint is of course brown. Entire mesonotum 
finely punctate. 
Male.—Length, 0.55"™" ; wing expanse, 1.47™™; greatest width of fore wing, 0.25™™, 
Color as in female, except that the tegule are brown and the scutellar spot is dull 
lemon-yellow, as large proportionally as in 2, but not so vivid. 
Described from 1 ¢ and 32’s bred from Lecanium hesperidum on or- 
range, Crescent City, Fla., by H. G. Hubbard. [Dept. Agr. Coll.] 
* Since the above was written I have received from Dr. Mayr the following concern- 
ing this species: 
‘““Was nun Ihre letzte Sendung betrifft, so steht Thr Leptomastix Dactylopii der 
europiiischen Art sehr nahe, und wenn Ihre Exemplare nicht etwa durch unnatiirliche 
Verhiiltnisse der Zucht im Zimmer besonders klein und unentwickelt geblieben sind, 
so kann Ihr Leptomastix ganz gut als eigene Art betrachtet werden, wenn auch die 
Unterschiede nur in der Grésse und Farbung vorhanden sind.”
