TRACHELAS. 
Apical spur of tibia shorter, more slender, and not curving 
upwards. Apex of bulb terminating in a very short slightly 
sinuous spine . 2. ee wee ee ee ee 
ui. Dorsal area of abdomen not scutulate. (Tibia of palpus one-half longer 
than broad, with a short slender obliquely depressed apical external 
spur. Bulb basally inflated, terminating in a spiraloid lamellular 
process, with a fine apical sinuous-uncate point.) . . . . .. . 
IL. Sternum smooth, with a few very shallow impressions, but no distinct 
granules, rugulosities, or punctures. (Tibia scarcely longer than broad, 
with a short slender spur on the outer apical margin directed almost 
straight forwards. Bulb much inflated at the base, with a broad slightly 
sinuous lanceolate spur at its apex.) . 2... ee ew ee eee 
B. Maxille with a more or less developed, individually variable, dentiform or 
triangular prominence on the external apical margin. Femur, patella, 
tibia, and protarsus of leg iii., or sometimes the tibia or the protarsus only, 
bearing an anterior marginal row of minute tubercles. Lower margin of 
fang-groove with 3-4 teeth (tooth i. usually very small and inconspicuous 
where four teeth are present). Basal segment of mandible straight, not 
excavate on the inner margin beneath. 
1. Tibia of palpus one-half longer than broad. Bulb basally inflated, with 
two short, apical, subsimilar, curved spines, their points directed 
upwards into the tarsal concavity. The tibia alone of leg ii. with 
an anterior marginal row of minute tubercles . . . . . . . . . 
2. Tibia of palpus twice as long as broad (7. bispinosus and T. truncatulus 
both bear a small broad apical spur). Bulb basally much narrower 
and truncate, with a single small straight spine at the apex. This 
spine has a minute cusp at its base, and a thin membranous 
process lies near it on the other side. Femur, patella, tibia, 
and protarsus of leg ii. with an anterior marginal row of minute 
tubercles . 2. 2 1. 1 ee ee ee ee 
Females. 
A. Lower margin of fang-groove with two teeth. Leg iii. without any anterior 
marginal row of small tubercles on the femur, patella, tibia, or protarsus. 
Sternum scarcely produced behind, obtusely pointed. 
i, Sternum smooth, without granulations or rugulosities. Oviducts opening 
into two large deep concavities separated by a narrow septum, which is 
less than half the diameter of one of them apart . . . . . . . . 
u. Sternum distinctly granulose or rugulose-impunctate. 
a. Oviducts opening into two deep medium-sized concavities separated by 
a septum equal to or wider than the diameter of one of them; the 
openings not visible. Size much larger, length 10 millim.. . . . 
6. Size much smaller, length 6-7 millim. Orifices opening into a common 
shallow concavity at its anterior margin.
