594 - MAJOR E. E. AUSTEN ON THE 



tergite ocliraceous-orange or orange-x'ufous ; sixth and seventh 

 tergites, fifth tergite except ai-ea just mentioned, and lateral 

 borders of preceding tergites, except silvery-white spots, clothed 

 with dark brown, bhxckish or black hair ; first tergite, except 

 lateral exti-emities, thinly clothed with fine, decumbent, glistening 

 ochraceous-buft' hairs, remainder of ochraceous-orange or orange- 

 rufous ai-ea of dorsum very sparsely clothed with short or minute 

 hairs of similar colour; venter mummy-brown, thinly clothed 

 with fine, darJc brown hair. Wings : markings very similar to 

 those exhibited by Pantophthalmus batesi Austen {cf. figs. 9 and 2); 

 costa, from a sliort distance beyond base, mainly cinnamon- 

 coloured ; veins elsewhere partly mummy-brown, partly sepia- 

 coloured, except in pale areas where they are cinnamon-buff; 

 teguliform swelling at base of costa ochraceous-bulf, large and 

 conspicuous, llalteres (in dried condition at any rate) sepin- 

 coloui-ed. Legs : first segment of all tarsi (except extreme tips), 

 also extreme bases of following segments in case of front pair, 

 honey-yellow, ochraceous-bufF or creain-bufi", clothed with short, 

 glistening, cream-coloured or cream-buff hair ; legs otherwise 

 clove-brown or chocolate- brown (last four segments of hind tarsi 

 sometimes blackish-brown or black), clothed with fine, similarly 

 coloured or blackish hair, which is closely set on hind femora and 

 tibisa, so that these segments, or at least hind tibiae, have a furry 

 appearance; claws black, sometimes russet-coloured at base; 

 pulvilli and empodia ochraceous-buff. 



Brazil. Holotype, precise locality unknown, before 1849 

 {Mrs. Noel); one paratype, Parana, about 1906 {E. DuJcinfield 

 Jones); a second paratype, precise locality unknown, ex coll. 

 J. Bigot (presented by Mr. J. E. Collin, F.E.S.). A third para- 

 type, without any indication of locality, but bearing two labels, 

 each with the words " seticornis, Wied.", and in one case with the 

 addition of "E Mus. Saund.-: 1867. \M" in J. 0. Westwood's 

 handwriting, is in the possession of the Hope Department, 

 University Museum, Oxford. The holotype is the specimen 

 called by F. Walker (List Dipt. Ins. in coll. Brit. Mus., Pt. i. 

 p. 210, 1848) Acanthomera seticornis Wied. The paratype from 

 the Bigot collection was placed by its original OAvner above the 

 XahQX'' A.frauenfeldi, Schiner." It may be of interest to note 

 that, in the wings of the paratype from Parana, the second 

 posterior cell .is closed and petiolate, altliough in all other respects, 

 apart from post-mortem shrinkage of the abdomen, the specimen 

 is normal. 



While the thoracic spots in the case of Pantophthalmus 

 variegatics, $ , are similar to those exhibited by both sexes of 

 P. vittatns Wied., though the posterior lateral spot is much 

 larger in the species characterized above, the distinctive tlioracic 

 stripes in P. variegatus will at once serve to separate it, not 

 only from P. vittatus, but also from any other Pantophthalmid 

 in which at any rate the female sex is known. 



It only remains to add that nymphs of the usual species
