Psyche 
[ March 
short anastomosing lines which do not extend onto dorsum 
of head excepting faintly at extreme base 1 , and with a 
slight tooth behind eyes; head sharply constricted at pos- 
terior margin of eyes, at this point narrowest and about 0.8 
the least subbasal width, the width across eyes nearly equal 
to greatest width; vertex slightly elevated, subconical, dis- 
tinctly produced and overhanging, bearing the anterior 
ocellus at its extremity, distinctly subreticulate, and with 
two pairs of small setae, one of them behind the posterior 
ocelli, the other on sides of vertex and very slightly in 
advance of front margin of posterior ocelli ; cheeks with 
about four pairs of similar small setae in addition to a pair 
behind and between postocular setae; postoculars nearly 
clear, expanded at tip, 83u long and 90u apart. Eyes 
strongly protruding, composed of relatively few large con- 
vex facets, about 0.3 as long as head, their width greater 
than 0.9 their interval and about three-fourths their length. 
Ocelli present, the posterior ones about 17u in diameter and 
about 0.6 as wide as their interval, the median ocellus with 
posterior margin far (12 u) in advance of anterior margin 
of eyes . Antennse (PI. 1, fig. 4) about 2.16 times as long 
as head, segments VI-VIII rather compactly united because 
of the very short and broad pedicels of VII and VIII, which 
are retracted into the apices of the preceding segments, VII 
with pedicel about 15 u wide and very nearly twice as broad 
as that of VI, VIII with pedicel 13 u wide; sense-cones 
slender, the number on inner (and outer) surface of seg- 
ments as follows: III 1(2), IV 1(2), V 1(1 + 1), VI 1(1 + 1), 
VII with the usual one on dorsum near apex; setse long, 
slender, pale and pointed. Mouth-cone broadly rounded at 
tip, supasssing middle of prosternum. 
Prothorax (PL 1, fig. 3) along median line of pronotum 
about two-thirds as long as head and (inclusive of coxse) 
about twice as wide as long, with a short vestigial median 
thickening, with a few faint lines of sculpture along poste- 
rior margin, and fused with posterior half of epimera; 
anterior marginal setse minute, the others nearly colorless, 
Mn order to show these at all in the figure, it has been necessary to 
represent them more conspicuously than they show in the specimen.
