FIGURES 408 and 409. Agraylea mul- 

 tipunctata Curt, (after Nielsen): 



408 - right mandible of pupa, ventral; 



409 - postsegmental plate of segment 4 

 and presegmental plate of segment 5 

 (left side). 



Tergites of abdominal segments 1-8 elliptical; anterior -angle seta 

 remarkably long; medioanal seta of dorsum of abdomen also very long on 

 the anterior segments; this seta is much thicker than the others on 

 segment 9. 



Anal legs (Figure 407) long in the first 4 stages; the sclerite of the basal 

 segment covers the greater part of the dorsal side, the whole lateral and 



ventral sides, so that the segment is 

 membranous only in the middle; the distal 

 seta of the sclerite, the adjacent seta of the 

 bridge are among the longest and thickest 

 setae of the young larva; the dorsal sub- 

 apical seta of the sclerite, which is rela- 

 tively short and thin, the lateral distal seta 

 much longer, thick at the base; the medially 

 situated sclerite "c" is small and rounded, 

 with a small thin seta. Claw long, thin at the 

 end, curved, with a narrow, transverse, 

 membranous stripe. Basal part of claw of 

 the young larva completely sclerotized 

 (unlike that of the full-grown larva); the 

 arrangement of the setae is the same, but 

 the differences in length are smaller. 



Pupa. Length of male pupae 3.8—4.2 mm; 

 length of female pupae 4.2—5.1 mm; antennae 

 of males reaching the middle of abdominal 

 segment 4, of female pupae the posterior 

 margin of the metathorax. Labrum almost semicircular; both pairs of 

 anterior-margin setae absent; median setae of the 4 basal setae rudimentary; 

 lateral setae long and curved. Mandibles (Figure 408) long, with a broad 

 ooq basal part and a narrow, slightly curved apical part; inner margin of the 



apical part finely serrated; outer setae straight, situated behind each other; 

 anterior seta shorter than posterior seta. 



Wing sheaths pointed, reaching in male pupae the posterior margin of 

 abdominal segment 7, in female pupae the anterior margin of segment 7. 

 Natatorial setae situated at the margin of segments 1—3 of the midtarsi. 

 Presegmental plates of holding apparatus (Figure 409) situated on segments 

 3—7, large, rounded anteriorly, pointed posteriorly; postsegmental plates 

 situated on segments 3—5, small, rounded; spinules on the plates brown; 

 their numbers are as follows: 111:5—14+ 6-14; IV:5— 15+ 9—12; V: 7-14 + 

 3—14; VI: 6—11; VII: 7— 15; spinules of varying size, some of them very small. 



Pupal case attached to the substrate with its broad side by 4 pairs of 

 ligaments near the anterior and posterior end; these ligaments originate 

 at the inner wall of the case near the substrate, near the angles of the slits 

 of the anterior and posterior openings; the ligaments are attached to the 

 substrate by separate, irregularly crossing filaments, which form plates 

 of irregular form; anterior and posterior openings of the case covered with 

 a delicate membrane, which connects both halves of the valve of the larval 

 slit of the case. 



Mode of life and habitats. In stagnant and running water, in plant 

 thickets; they avoid small and shallow water bodies, like puddles, ponds and
