behind the eyes. Anterior margin sUghtly produced between the 

 antennse. Eyes large, black, not protruding, very sparsely and 

 minutely pilose, occupying about three-fifths the width of the head. 

 Ocelli light reddish, large, fairly well separated, the posterior ones 

 just behind the center of the eyes and near their inner margins; 

 anterior ocellus somewhat directed forward; margined inwardly with 

 dark-reddish-brown crescents ; a long, slender, yellowish-brown spine 

 in front of each posterior ocellus, other spmes upon head few and 

 minute. Mouth cone long, narro-\ving abruptly to the middle, thence 

 very slender to the tip, reaching posterior margin of prosternum. 

 Maxillary palpi long and slender, first and third segments of equal 

 length, the second about three-fifths as long as first, light yellowish 

 brown. Mouth cone darker brown than head, darkest at tip. Labial 

 palpi very slender. Antennse two and one-half times as long as the 

 head, inserted below the front. Relative lengths of segments as 

 follows : 



12 3 4 5 6 7 8 



9 13 .16 15 10.5 15 3.4 5 



Segment one broadest, sHghtly broader than long, broadest at base; 

 segments one, four, five, and six concolorous with head or only 

 slightly lighter, seven and eight lighter brown, three light yellowish 

 with a slight tiage of brown. Segment three is stalked and has a 

 pseudo joint near the base. Long spines upon segments are slender 

 and light yellowish. A branched sense cone stands upon the upper 

 side of segment three near the tip and a similar one is borne on the 

 under side of four near the tip. Segment one bears a transverse stria 

 near the base. * 



Prothorax slightly broader than long, broadest behind, hind angles 

 broadly rounded, and bearing two long spines. No long spines at 

 front angles. A row of four small spines stands on hind margin 

 between meson and spines at angles. Other spines upon prothorax 

 few and inconspicuous. Mesothorax rounded at anterior angles ; each 

 of which is produced into a shoulderlike process; mesonotal plate 

 transversely striate, bearing one long spine at each lateral angle, 

 spines on posterior margin inconspicuous. Metathorax tapers but 

 slightly posteriorly, metanotal plate longitudinally striate, with two 

 pairs of spmes on the front margin, the pair toward the middle being 

 much the larger. Wings reaching nearly to tip of the abdomen; 

 breadth at the middle about one-eleventh their length; with two 

 broad white bands, the first beginning near base and extending to end 

 of first third of wing, the second beginning at about two-thirds length 

 of wing and extending nearly to the tip. Basal two-fifths of scale is 

 light brown, the remainder being included in the white band, middle 

 and tip of wing light brown. Veins in fore wing extend nearly to 

 tip of wing. Spines on veins arranged at regular intervals except in
