Psyche 
[June 
Male: Length: head (mandibles excluded) 1.25 mm.; 
thorax 2 mm. ; overall length 6.5-7 mm. 
Upper surface of the head with fine, wavy, longitudinal 
rugae over most of its middle third. These rugae form few 
reticulations. The rugae of the lateral portions of the head, 
the occipital angles, the entire occipital border and the gula, 
notably reticulate. The surface between the rugae dull and 
densely punctured, the punctures appearing as tiny craters 
under high magnification. Frontal groove, frontal area 
and the clypeus slightly shining. Mandibles longitudinally 
striate and a little more shining than the clypeus. 
Entire thorax feebly shining to dull with punctato-rugose 
sculpture, the punctures very dense. Rugae on the prono- 
tum, mesothoracic sternite and episternite feeble, often 
replaced by punctures on the front part of the segments. 
Scutum, paraptera and scutellum with moderately de- 
veloped, longitudinal, reticulate rugae in addition to the 
dense punctures. Metathoracic sternite with coarse longi- 
tudinal rugae which turn upward on the sides of the epino- 
tum. Basal face of the epinotum with coarse, reticulate 
rugae. Rugae on the declivious face of the epinotum trans- 
verse. Anterior peduncle of the petiole finely punctate and 
more shining than the remainder of the petiole. The an- 
terior face of the node of the petiole densely and more 
coarsely punctate. Crest and rear face of the node and the 
posterior peduncle with reticulate rugae in addition to the 
punctures. Postpetiole densely punctate but not rugose. 
Abdomen smooth and shining with extremely fine, scattered, 
piligerous punctures. Coxal joints, antennal scapes, fore 
femora and tarsi delicately reticulo-punctate. Middle and 
hind femora with similar but feebler sculpture. 
Erect hairs of moderate length, yellow-brown, evenly 
curved, tapered and well-separated. Abundant on the dor- 
sum of the thorax, except on the basal face of the epinotum, 
where they are restricted to the angle between the basal 
and the declivious faces. Erect hairs on the head about 
equally numerous on the upper and lower surfaces. Erect 
hairs on the petiolar nodes notably sparser than those of 
the thorax. Erect hairs on the gaster very fine, much shorter 
than those of the thorax and largely limited to the rear 
edge of each segment. The remaining gastric hairs very
