130 ENTOMOLOGICAL NEWS. [ Mar., 716 
at the end, dark, but the knob white as are most of the spines on the 
body. Eyes dark in color, rather large. Ocelli rather large. Posterior 
pair placed near the margin of the eyes and anterior to the middle; 
anterior pair directed forward. 
Mouth cone very long and sharp-pointed, reaching fully to (and 
sometimes beyond) the posterior border of the prothorax. 
Antennae one and two-thirds times as long as the head. Segment 
1 dark brown, only a little lighter than the head; segment 2 brownish. 
yellow, darker at the hase; segments 2 to 7 bright yellow; 8 brownish 
yellow; segment 3 averaging only slightly shorter than 1 and 2 to- 
gether, in some individuals longer, in others shorter; sense cones and 
spines about one-third the length of segment 3, very pale in color, 
aimost white. 
Prothorax subtriangular in outline, seven-twelfths as long as head 
and over twice as broad as long, measuring from outer angles of 
coxae. A very long, stout, knobbed spine on each posterior angle; a 
short, thick one on each anterior angle, and between them one inter- 
mediate in length; a pair along the anterior border. 
Mesothorax one-fifth broader than prothorax. Legs rather long and 
slender, concolorous with the body except the tarsi which are a lighter 
brown. The fore tarsi often darker than the meso- and metatarsi; 
fore femora considerably less than half as wide as the head, sparsely 
provided with short, very stiff, almost spine-like hairs; these are longer 
and less stiff on the other femora and on the tibiae and tarsi. 
Wings well developed, not at all constricted in the middle; hairs long 
and copious, from eight to thirteen (usually ten) near the end forming 
a second row; membrane brownish towards the base where it is pro- 
vided with a short vein which bears three very heavy, long, knobbed 
spines. 
Abdomen with rather convex sides, at the widest portion (which is 
about the fourth segment) one-ninth wider than prothorax. Posterior 
angles from segments 4 to 9 with spines; those on segments 6 to 9 long 
and heavy. Tube rather narrow, tapering to nearly half its diameter 
at base; length nearly three times the width at the base; terminal hairs 
shorter than the tube. 
Described from nine females taken from wild grape vine, 
April 23, 1914, at Gainesville, Florida. Males unknown. 
Type in the collection of the National Museum.
