eyes considerably more densely and conspicuously pubescent; antennae 
(Fig. 3) with the flagellum proportionately shorter, the funicle only five- 
jointed, the club solid, but in general shape agreeing with the female; the 
scape with a narrow ventral exfoliation from the apex to a little more 
than three-fourths of the length excluding the radicle, this exfoliation in 
the female being much smaller and not reaching to the middle; abdomen 
somewhat wider than long, rounded at apex and hardly more than one-half 
as long as the thorax, therefore, considerably smaller, more depressed than 
in the female, and with the venter not at all vomeriform.

Described from 13 females, 8 males, reared from Pseudo- 
coccus brevipes Ckll. (bromeliae of authors) collected in Mexico 
by Mr. Osborn, as follows: 1 female (holotype) reared August 
10, 1922, from its host on Tillandsia, El Potrero, Vera Cruz; 
12 females, 3 males (paratypes), reared from mealybugs on 
Tillandsia and other Bromeliaceous plants, El Potrero, on July 31, 
and during August, 1922; 2 males (allotype and paratype) with 
the same data, but collected in March, 1923; 3 males (para- 
types) from mealybugs on a Bromeliaceous plant, Rio Seco, 
Vera Cruz, March 15, 1923.

Zeteticontus perkinsi n. sp. Fig. 4. 
Female. Head moderately thick fronto-occipitally with the face slightly 
inflexed; in dorsal view appearing semi-circular with the occipital outline 
broadly and roundly emarginate; in side view appearing thickest fronto- 
oceipitally at the anterior ends of the eyes, the planes of the face and 
frons meeting in an angle of distinctly more than 90 degrees; in frontal 
view appearing as wide as long and nearly circular in outline with the 
broad oral margin truncate. Occiput moderately deeply concave; eyes of 
medium size, broadly oval, about one-third longer again than wide, pos- 
teriorly contiguous with the occipital margin, the inner orbits somewhat 
diverging anteriorly; frontovertex occupying about a third of the total 
width of the head, and about one-third longer than its own width at the 
anterior ocellus; ocelli rather large, disposed in what is slightly more than 
a right-angled triangle, the posterior pair somewhat less than their own 
diameter from the occipital margin, and not more than one-half as far 
from the margin of the eyes. Cheeks in side view of head rather wider 
than long and distinetly shorter than the width of the eyes, the genal 
suture very obseure; facial impression subcireular, extending for about
