( 5) Lihelhda eqtiestris, F. (J . Type. 

 { = Neurothemis tullia, Druiy.) 



ZaWs :— " Libellula equestris Fabr. Sp. Ins. No. 20"; 

 square white ticket, " Africa/' written. 



Diagnosis: — ''L. alis diinidiato nigiis^ fascia media nivea. 

 Habitat in Africa sequinoctiali, Mus. Dom. Banks." — F., 

 tSpec. Ins. i. p. 523, no. 20 (1781). 



This insect agrees very well with Drury's figure of his 

 Libellula tiillia, adult (^ , from Bombay (111. Ex. Ent. ii. 

 pi. xlvi. fig. 3; 1773). That figure, however, fails to show 

 the transverse white band in the wings, and is also a little 

 larger than Fabricius*s type, the hind wing measuring 22 mm., 

 as compared with 21 mm. In our type the last antenodal is 

 continuous in both fore wings. The reference to Africa is, of 

 course, a mistake, as the genus Neurothemis is entirely 

 unknown from that continent. 



(6) Lihelhda marginata, F. J" • Type. 

 { = Palj^opleura Incia, Drury.) 



Labels : — " Libellula marginata Fabr. Sp. lus. No. 24 " ; 

 square white ticket, "Africa," written; round blue ticket, 



a 63 " 

 47' ^ 



Diagnosis : — " L. alis nigris, anticis macula apicis, posticis 

 margine albis. Habitat in Africa a'quinoctiali. Mas. Doui. 

 Banks."— i\, Spec. Ins. i. p. 523, no. 24 (1781). 



Con)paring this specimen with the plate of coloured figures 

 of Pulpopleura liicia in liis's monograph of the Libellulinse 

 (Coll. iSelys, Libell., fasc. ix. pi. i.), we find that the pattern 

 of the fore wing is intermediate between the first and second 

 of those figures, while that of the hind wing is something 

 bLtween the second and third figures. 



(7) lAhellida ferrnginata, F. J . Type. 

 (= Crocothemis serviliay Drury.) 



Label: — "Libellula ferruginata Fabr. Sp. Ins. No. 11. '' 

 The specific name was written originally " ferruginea,'' and 

 was altered subsequently to ''ferruginata.''^ 



Diagnosis : — " L. alis basi flavescentibus, corpore obscure 

 ferrugiueo. Habitat ad Cap. Bon. Spei. Mus. Dom. Banks.'''' 

 — F., Spec. Ins. i. p. 521, no. 11 (1781). 



L. ferruginata, F., has been erroneously identified with the 

 common African species Crocothemis erythrcea, BruU^, because 

 the Cape of Good Hope was stated to be its habitat. This
