Psyche 
[June-Sept. 
reaching about to level of basal third of second antennal 
segment, divergent and blunt; postocular tubercles distinct 
but not reaching so far as outer margins of eyes; upper 
surface feebly elevated with granular areas in front of and 
behind eyes and with two moderately elevated, anteriorly 
divergent longitudinal rows of about four large granules 
each at middle of vertex ; eyes small, less than half as wide 
as interocular space, 5::13. Antennae equal in length to 
head, the proportion of segments one to four as 3:5:5:8; 
first and third segments cylindrical, second roundly clavate, 
fourth fusiform. Pronotum just twice as broad across 
humeri as long on median line, one-seventh shorter than 
head, 18 : :21 ; disk moderately convex with a distinct trans- 
verse impression at middle interrupting the four distinct, 
posteriorly divergent longitudinal carinse ; subparallel 
median carinse produced forward slightly beyond base of 
head ; lateral margins nearly straight but for the deep notch 
at transverse impression, roundly lobed. Scutellum a little 
less than three times as long as pronotum, 51 : : 18, and about 
half as broad as long ; broadest at base where it is somewhat 
less than two-thirds as broad as long, 28: :51, then with the 
sides concavely sinuate to narrowest point just behind middle 
where it is distinctly less than half as broad as long, 24 : : 51, 
widening posteriorly to about half as wide as long and then 
rounded to broadly rectilinear apex; depressed portion of 
disk evenly punctate; longitudinal carina well elevated, im- 
punctate; lateral carinse coarsely granular, almost roundly 
tuberculate basally; four anteriorly directed projections of 
basal elevation but feebly developed. Abdomen only mod- 
erately dilated, about four-fifths as wide as pronotum, 
35:43; connexival surface finely granular, the lateral mar- 
gins of segments each with three feebly developed, rounded 
tubercles. 
Size, male, length 2.5 mm., width (pronotum) .87 mm., 
(abdomen) 1.07 mm. 
Holotype: No. 4634 (male), Museum of Comparative 
Zoology, Harvard University; in Haren collection of Baltic 
amber insects. 
Closest to the European ghilianii (Costa) but smaller 
than that species with broader head, less prominent tuber- 
cles on head, pronotum, and base of scutellum, and entirely
