as follows: “I have compared them (i. e., the Hawaiian speci- 
mens forwarded under the name of Blepyrus mexicanus) with 
the torso of Cameron’s type of Eucyrtus insularis, and so far 
as I can see the two are identical.” 
Dr. Perkins in the Introduction to the Fauna Hawaiiensis 
(Vol. 1, Part 6, p. cvi, 1913) synonymized Blepyrus mars- 
deni Howard with msularis, but having failed to state his 
grounds for doing so, his action was not accepted by me in 
my former papers on Hawaiian Encyrtidae. It now appears 
that this synonymy was based on the Blackburn specimen men- 
tioned above, and was of course correct. 
GENERIC CHARACTERS OF BLEPYRUS HOWARD. 
Female. Form short, compact; head thin, menisciform, somewhat 
wider than the thorax; eyes very large, vertical, continuous with the 
occipital margin aboye, finely, rather densely, and shortly pubescent; 
frontovertex moderately wide, or about one-fourth-as wide as the head, 
abruptly widened behind the oeelli; the latter arranged in a large, nearly 
equilateral triangle, the posterior pair close to the eye margins, and about 
their own diameter from the occipital margin; cheeks short, or about 
one-fifth the length of the eyes; face with a semi-oval scrobal impression 
reaching upward between the eyes, the depths of the scrobes in the form 
of shallow grooves converging from the antennal sockets, but not meeting

above, the facial prominence between the antennae broad and low. 
Antennae inserted rather far apart close to the clypeal margin, short 
and strongly clavate; scape slender, cylindrical, reaching nearly to the 
middle of the eyes and distinctly beyond the scrobal impression, pedicel 
a little longer than the first three funicle joints combined, the apical 
stalk connecting with the funicle very strongly capitate at its apex, 
forming a distinct but false ring-joint; funicle joints all short and trans- 
verse, the sixth over twice as wide as long; club very large, irregularly
