(text-figure 141) are slender and slightly broadened toward the tip with denticulations along the convex border. The compound setae (text-figure 142) have rather large basal joints with denticulated ends, each terminal joint being small with apical and subapical teeth and a striated hood. I was unable to find any pectinate setee. The acicula (text-figure 143) is yellowish brown in color, rounded and slightly darker at the apex. In the maxilla (text-figure 136) the carrier is longer than the forceps, almost rec- tangular in outline, and light yellowish-brown in color. The forceps are darker than the carrier, their basal portion being more than half their length. The proximal plates have each 3 large teeth. On either side distal to these is a row of 3 plates whose appear- ance depends on their position. The median one in each row is thicker than the others and has the appearance of being rolled at the end. The others are flat plates, more or less joined together. Between the proximal plates is a thick plate occupying the posi- tion of the unpaired in other species. In the f
