Descriptions of Two New Species of Encyrtidae From Mexico 
Reared from Mealy-Bugs (Hym., Chalcidoidea). 
BY P. H. TIMBERLAKE. 
(Presented by title by Mr. Fullaway at meeting of December 7, 1922. 
The following species of Encyrtidae were discovered by Mr. 
H. T. Osborn in the State of Vera Cruz, Mexico, in the course 
of his explorations for natural enemies of mealy-bugs to introduce 
into the Hawaiian Islands. Of these Pseudaphycus utilis has be- 
come established at Honolulu, but Coelaspidia osborni has not 
been recovered as yet, although liberated in large numbers. The 
types are in the collection of the Hawaiian Sugar Planters’ 
Experiment Station, and paratypes will be distributed to various 
museums. 
Pseudaphycus utilis n. sp. Figs. 1-4. 
This species has a different habitus from all other species of 
Pseudaphycus known to me, but I think that it is properly 
placed in this genus. It is easily distinguished from all the 
described species of the genus and of the closely allied genera 
Acerophagus and Bothriocraera by its comparatively large size, 
entirely hyaline wings, and the bright yellow coloration with 
blackish pubescence on the mesonotum. In my table of the 
species of Pseudaphycus (Proc. U. S. Nat. Mus., Vol. 50, p. 570, 
1916) it runs to graminicola, but differs in having the face 
and cheeks of normal length, the coloration bright yellow, the 
pubescence of the mesonotum dark instead of whitish, the abdo- 
men much shorter or hardly longer than wide, the ovipositor 
more briefly protruded, the wings considerably wider, etc. The 
species is a parasite of Pseudococcus nipae (Maskell) and 
has become established at Honolulu from material collected at 
Orizaba, Mexico, by Mr. Osborn in the spring of 1922. 
Female. General form robust, the thorax being almost as thick dorso- 
ventrally as wide; head rather thick fronto-occipitally, the outline in dorsal 
view broadly elliptical with the occipital margin slightly and broadly emar- 
ginate at the middle, the surface strongly convex from side to side; as seen 
from the side the outline is triangular with the facial side about a fourth 
longer than the dorsal side, the angulation well rounded off; as seen from
