inner discal cell. Anterior coxa, trochanter, and base of femur with 

 black maculations, remaining parts yellowish; middle and hind legs 

 yellowish. Prosternum with two broad rows of golden short ap- 

 pressed hairs, making it appear lighter. Mesosternum hghter on 

 anterior half. Metasternum lighter than general body color. An 

 irregular reddish brown broad stripe along the abdomen about midway 

 from the median Hne to the upper margin. Connexivial segments 

 fuscous; shghtly hghter on anterior halves. 



Dorsal parts, except membrane, sparingly covered with very small 

 bulbous setigerous spines. Head from tip of jugae to anterior margin 

 of pronotum nearly one-half length of pronotum. Preocular margin 

 to apex of antenniferous tubercles equal to postocular margin, Jugae 

 slightly converging at tip; reaching to one-fourth of first antennal 

 segment. Antennal tubercles outwardly without spinules. Ocelli 

 closer to the eyes than to each other. Before eyes, as in figure 80/, 

 armed below with two 1-setigerous spinules; behind eyes laterally 

 with five large setigerous spinules and four or five smaller spinules 

 grouped above last two. Genae anteriorly acute. Basal antennal 

 segment with long hairs below and on inner sides only; one-fifth 

 shorter than head from apex of antenniferous tubercle to collum; 2K 

 times as long as preocular margin. Second segment one-half times 

 longer than first, with decumbent and straight hairs, slightly longer 

 than diameter of segment. Third segment one-fourth length of first, 

 pilose; fourth segment twice as long as third, pilose. Beak relatively 

 slender; proportions of segments 36:16:13. 



Pronotum with lateral margins unarmed, nearly twice as long as 

 wide; anterior lobe slightly more than IK times as long as posterior 

 lobe; posterior lobe with a low longitudinal ridge on either side of 

 middle, contiguous in front; shorter ridges near posterior angles of 

 the pronotum. Apex of scutellum with a small black tubercle, romided 

 at tip. Membrane with apical inner margin sinuate; apex nearly 

 acute, reaching to one-third of sixth abdominal segment. Discal cell 

 of corium three times as long as wide, except posteriorly bounded by 

 fuscous veins. Anterior trochanter with thi-ee or four black spines. 

 Incrassate fore femora inconspicuously pilose with globose setigerous 

 spines, armed below with a row of spines of uneven length, diminish- 

 ing in size toward apex. Fore tibia, midlegs, and huid legs with rows 

 of same kind of setigerous spines. Anterior margin of propleura and 

 rim of acetabulum with spines. Inferior margin of pronotum with a 

 row of more prominent rounded setigerous spines. Venter longitudi- 

 nally ridged to end of thu'd visible segment and carinate to end of 

 sixth. Apical angles of connexivial segments acutely prominent; 

 margins with setigerous spines.
