FIGURE 747. Amphipsyche pro 

 luta McL. Covering setae of head 



middle, conical-convex, with rows of light setae laterally; primary seta 

 thicker than others. Cardo light brown, with 6 or 7 long setae at base. 

 Stipes narrow, pale brown, its setae numerous, forming a basal and an 

 531 apical tuft, longer in basal tuft. Palpifer yellowish, its distal seta strong; 



mediobasal seta small and light. Galea and 

 maxillary palps brownish yellow, 4th palp 

 segment almost as long as other segments 

 together. Labium blunt; mentum brown, 

 short, with a smooth, straight margin; labial 

 palps rudimentary. 



Nota of thoracic segments (Figure 752) 

 yellow, brownish yellow in some places. 

 Anterior margin of pronotum with a broad 

 median indentation and broad processes 

 (Figure 752, A); anterior margin chestnut 

 brown, with brownish yellow, strongly 

 sclerotized anterior angles; lateral border like 

 anterior margin in the anterior quarter, 

 brownish black and broader posteriorly in its 

 other part; posterior margin light brown, 

 slightly darker in the middle; it consists of 

 2 stripes separated by a light space in its 

 greater part; large groups of large, light spots 

 laterally in each half of the sclerite. Light, 

 small spinules at anterior margin; these 

 spinules are larger laterally near the angles; 

 a brownish, moderately long seta in middle of 

 each half; 4 short, light setae lateral to this seta, at margin; 2 of these 

 setae are situated in broad angle part of margin; surface of this part with 

 several short setae (one of them near anterior angle) and several very small, 

 light setae; 2 short setae laterally in this part and at lateral margin. 

 Relatively long, anteriorly displaced medioanal primary seta, largest seta of 

 the sclerite, situated in the anterior third at a distance from median suture; 

 whole surface of sclerite (mainly in anterior half) with small hairlike, light 

 covering setae and several larger setae which are simple or have 3 or 

 4 branches. 



Meso- and metanotum (Figure 752, B, C) weakly sclerotized, light yellow; 

 setae thin and light. Mesonotum broad, slightly shorter laterally; anterior 

 margin smooth, mainly light, without border; a border is present only near 

 the angles; anterior angles dark, reddish brown; border of lateral margin 

 broad in middle, blackish brown; border of posterior margin narrow, 

 yellowish, with white dots; median spot in form of a curved, dark reddish 

 brown stripe with yellowish brown ends; oblique stripe on sides of sclerite 

 brownish. Light part of anterior margin with dense small hairlike chetae; 

 dark lateral parts with 9—11 strong, light, short setae; hairlike covering 

 setae also on surface, mainly in anterior half, sparser posteriorly; 

 3 (sometimes 4) small, light, strong setae situated anteriorly, near margin; 

 3 similar small setae and several very small thin setae in anterior angle; 

 medioanal surface seta long, almost reaching middle of segment; a 2nd 

 large seta situated at a distance, closer to anterior third of sclerite; 

 several not quite symmetrical, small, light setae along median line and on
