perceptible infumation. On the hind margin of each fore wing 
there are about forty-five to fifty interpolated cilie. 
Abdomen long and slender, with the basal segments of sub- 
equal length and width, the apical segments longer than broad. 
Ninth segment strongly narrowed posteriorly, a third the length 
of the tube; this segment in the basal portion with the margins 
straight and subparallel, in the apical third a little converging; 
its breadth at base about one and one-half times its breadth at 
apex. All abdominal segments near the hind margin set with 
long bristles; those of the ninth about as long as the tube, 
those of tube a little shorter. The three basal segments (2 to 
4) dorsally with two pairs of well-developed wing-retaining 
spines, the following without such. On the ventral side of the 
ninth abdominal segment a pair of long and very thick, straight 
spines (fig. 4). 
I have allowed myself the pleasure of naming this interest- 
ing new species after Prof. Charles Fuller Baker, who dis- 
covered it in the Philippines.
