scribed in diagnosis. Paraproctal sensorium with 7 trichobothria and 
2 setae without basal rosettes or with these poorly developed. 
Color (in alcohol). — Same as in male. 
Type locality. — Nova Teutonia, Santa Catharina, Brazil. 
Records. — St. Pat’s, Arima Valley, Trinidad, W.I.

dried fern leaves. 
Troctopsocus similis, new species ( 9 ) 
Diagnosis. — Wing markings essentially same as in T. separatus 
(Roesler). Spermathecal sac with long slender basal region and no 
constriction between wide and slender regions. Ovipositor valvulae: 
basal arms of first and second valvulae very short; secondary lobe 
of third valvula exceedingly spinose. 
Female. — Measurements (Table I). 
Morphology. — Lacinial tip (fig. 70) with median cusp distinctly 
bidenticulate, lateral cusp with divided apex, 2 preapical denticles, 
one short and rounded, other longer, more slender, and protruding 
at an angle from cusp. Subgenital plate as described for the genus, 
and as figured for T. bicolor. Stem of T-shaped sclerite curved in 
preparation. Ovipositor valvulae (fig. 59) as described in diagnosis. 
Paraproctal sensorium with 7 trichobothria and 2 setae without basal 
rosettes. 
Color (in alcohol). — Head, thorax, and legs largely dull ivory 
yellow. Head extensively marked with medium brown as follows: 
a broad band on each side of epicranial suture, each band bending 
laterally just before reaching lateral ocellus to end at antero-mesal 
margin of compound eye. Compound eyes bordered by medium 
brown spots. Frons bordered ventrally and laterally with medium 
brown and in middle with medium brown mark in form of rounded 
letter M. Genae behind antennal bases marked with reddish brown. 
Compound eyes black. Antennae reddish brown. Thorax marked 
on each side with 3 longitudinal parallel stripes of reddish brown, 
the lowest one mostly confined to coxal bases. Thorax dorsally 
extensively marked with reddish brown, but sutures and an elongate 
central spot dull ivory yellow. Abdomen with entire ventral surface 
dark reddish brown except for colorless posterior half of subgenital 
plate. Sides of abdomen dull ivory yellow, somewhat darker on
