139 
with complete, wide peripheral ring. 
Male. — Measurements (Table I). 
Morphology. — Lacinial tip (fig. 57) : lateral cusp with two den- 
ticles set at decided angles to cusp ; bluntly pointed denticle at base 
of cusp. Hypandrium with distal margin approximately straight. 
Phallosome typical of the genus. Clunial comb (fig. 43) as described 
in diagnosis. Paraproctal sensorium with field of 6-8 trichobothria 
and 1-2 setae without basal rosettes. 
Color (in alcohol). — Except for abdomen, almost exactly as in 
T. martinicus , the chief differences as follows : a distinct brown spot 
antero-mesad to each compound eye; pair of spots below ocelli 
distinctly separate; lateral thoracic stripe generally with less reddish 
brown, especially paler on prothorax. Wing markings same as in 
T. intermedins. 
Female. — -Measurements (Table I). 
Morphology. — Subgenital plate typical of the genus. Ovipositor 
valvulae ( fig. 45 ) with first valvula bearing anterior process from 
base of shaft, this process in contact with sclerite of spermathecal 
opening. Sclerite of spermathecal opening (fig. 56) as described in 
diagnosis. Paraproctal sensorium same as in male. 
Color (in alcohol). — Same as in male. 
Type locality. — Savanne Edmund, St. Lucia, W.I. (elevation 
approximately 600 m.), August 23, 1961, E. L. Mockford collector. 
Holotype cf , allotype 8 d and 9 9 paratypes and 8 nymphs. The 
types are for the present in the author’s collection. 
Habitat. — The type series was beaten from dead fern leaves on 
the edge of a road bordering a forested region.
