Psyche 
[September 
ing with the dark head. Last segment of maxillary palpi narrowly 
securiform, 0.15 X 0.08 mm. Eyes moderately large and prominent, 
0.3 1 X 0.20 mm, moderately coarsely faceted, occupying much of side 
of head, with curved setae ca. 0.02 mm long at the intervals of the 
facets. Antennae of same general proportions as eryngii but the inter- 
mediate segments stouter, 5-10 being subtriangular and gradually 
stouter, and subtruncate at base. Measurements in 0.0 1 mm: 18/8, 
8/6, 9/6, 9 / 6 , 9 / 8 , 9 / 8 , 9 / 8 , 9 / 9 , 9 / 9 , 9 / 8 , 14/8. 
Pronotum of form of decoratus, 0.76 mm long, 0.46 wide at base, 
0.68 maximum and 0.28 at collar. Punctures denser than on head, 
longitudinally oval, narrowly separated. A few of them are slightly 
confluent longitudinally, but almost all are distinctly separated. The 
disc is slightly flattened, but almost evenly convex. Elytra suparallel, 
1.98 mm long, 0.79 mide at the well-marked humeri, 1.02 maximum, 
somewhat flattened, with the omoplates and postbasal transverse im- 
pression barely indicated and the suture not elevated. Surface as in 
decoratus , the punctures fine and 0.04 mm from center to center; 
setae appressed but not closely so, slightly curved, 0.05 mm long, 
noticeably coarser and shaggier than in decoratus; tactile setae sub- 
erect to erect, 0.04 mm. There is a narrow slightly darkened strip 
along the suture, ca. 0.18 mm wide and most evident on the middle 
third. The region of the omoplates is also slightly darkened, but 
probably because the slightly translucent elytra reveal the top of the 
thorax. Wings apparently of full length. Underside as in decoratus, 
but mesepimera more distinctly visible. Legs rufescent, the coxae 
darkened toward base, the hind coxae mostly dark. Front femur 0.49 
X 0.18 mm, front tibia 0.44 X 0.08, hind femur 0.64 X 0.20.

Ischyropalpus puteifer, new species 
(Figs. 4-8) 
3.53-4.24 mm, brown with the appendages rufescent, to all rufes- 
cent; subopaque, moderately slender and flattened. Prothorax, 
especially of male, unusually large. Front and hind femora of male 
with a pit on the surface facing the tibia. 
Holotype <$ : Length 4.24 mm. Head 0.67 mm long, 0.72 wide 
across eyes, 0.67 just behind, with short tempora, the base gently and 
evenly rounded between the poorly defined temporal angles, moderately 
retrosalient. Disc somewhat flattened, evenly covered with sharply 
defined flat-bottomed punctures 0.03 mm from center to center even 
on frons, the punctures only narrowly separated but not all con-
