28. .4gi*ioii cingnlatiini B. P. 82.3. [Lesfes.] 



Aus Neu-Holland, beide Gescblecbter in der Hallenser Sammlung. 



One male (T), r»iie female (J) under the lilac drawer-label " cin- 

 gulatum Holl. nov." in B.'s hand, at Halle; no pin-labels. They 

 agree with de Selys' description (Bull. Acad. Roy. Belg. — 2 — xiii, 

 p. 334, 1862) of Lestes cingulata, l)ut in his description of the ab- 

 domen 'dessus' and ' dessous ' should be transposed. As his de- 

 scription was made from imperfect individuals, the following notes 

 were made from the types to supply the deficiencies. 



% (type). Pale blue basal spot on the secoml abdominal segment rounded 

 posteriorly and, on the mid-dorsal line, reaching to a little more than one-third 

 the length of the segment. Basal aunnli on 3-8 (on 8 very narrow) also pale 

 blue. 



Superior ajipendages (PI. I, fig. 1) as long as 8. and longer than 9 or 10. Viewed 

 from above, they are curved inward at two-fifths their length, the apical three- 

 fifths being approximately straight; the two consequently come in contact at 

 their apices ; external margin for rather more than the middle third denticulated ; 

 a .strong, oblong, basal tooth, directed downward (ventralward). backward and 

 inward, with its apex truncated almost at right angles to its sides; in the middle 

 third a second, very acute, slightly longer, infero-internal tooth, directed back- 

 ward, only partially visible when the appendage is viewed from directly above; 

 terminal third dilated cylindrically on the inner side before the aj)ex, which is 

 obtuse, rounded and somewhat hairy.
