Bureau of Entomology, U. S. Dept. Agriculture. 
1. Pseudleptomastix new genus of the Ectromini. 
Female: In my table to the earth’s genera runs to Paraleptomastix 
Girault but the form is not robust, the head not lenticular, the face 
deeply inflexed, the scrobes joined above, the stigmal vein subequal to 
the marginal which is about two and one-half times longer than wide, 
yet distinctly somewhat shorter than the postmarginal. The costal cell 
is extremely narrow, practically obsolete for its greater length. Hind 
legs normal. Frons broad, sloping, the cheeks nearly as long as the 
eyes. The two teeth of the small mandibles acute but unequal in 
length. With the general habitus of Ooencyrtus. Hind tibial spur very 
minute. 
(1) Pseudleptomastix squammulatus new species. Female. Genotype. 
Length, 1.00 mm. 
Dark metallic green, the thorax purple, the abdomen black or 
nearly, the fore wing slightly dusky throughout, its venation dusky 
yellow. Antenne black but the club, apex of scape and of pedicel rather 
broadly, yellowish white. Mandibles reddish. Legs yellowish white 
except caudal coxze and femora to tip, a broad dusky band around 
middle femora near base and a spot above at apex. Head coarsely 
scaly, the thorax dorsad rather finely so, the triangular scutellum 
somewhat finer and denser than the scutum; abdomen across base 
densely scaly. Scutellum not reaching base of the abdomen, the 
axille a little separated. Abdomen about as long as the thorax, 
pointed. Pronotum arcuate, linear; scutum wider than long. Prox- 
imal joint of the hind tarsus much the longest. Pubescence on scutum 
white, not dense, short. Tegule large, white. Pedicel twice longer 
than wide at apex, longer than any of the funicle joints which are 
subequal, each nearly twice longer than wide, the club slightly wider 
than the funicle and about half its length, each of its joints a little 
shorter than one of the funicle joints. Oblique hairless line closed 
caudad, with many lines of cilia proximad of it. Fore wings normal, 
neither narrow nor especially broad, rounded at apex. 
Described from two females labelled ‘‘State Insectary, 
California, 675’’ Fresno, California, from mealy bugs on 
grape. 
Type: Catalogue No. 19835, U. S. N. M., one female
