Aufidellus , Kirk., cannot be separated from Anfidus. The type 

 of Stal's genus {A. trifasciatus) is in the British Museum, as is also 

 a specimen of the species described by Kirkaldy as .4. australensis. 

 The differential and only characters given by the last-named writer, 

 " pronotum posteriorly is almost evenly rounded and the costal 

 margin is not arched basall}'," constitute (when the species is ex- 

 amined) only very moderate specific differentiation. In his des- 

 cription of another proposed genus, Aufiterna,^ he whites" posterior 

 margin emarginate, while it is truncate in Aufidus." This is inac- 

 curate ; in the type of Aufidus {A. trifasciatus), the posterior 

 pronotal margin is distinctl}' emarginate ; neither did Stal make 

 that structural character a generic distinction ; he simply wrote 

 " Thorax sexangularis. " On the other hand Auflterna, Kirk., is 

 apparently only to be separated from Aufidus b}' the venation of the 

 tegmina, " 3 discoidals (subapical), 4apicals well marked, while there 

 are another 5 small cells marked off on the costal cell." It will 

 be seen b}* the figure here given, that all these characters are more 

 or less represented, and that the divisions of the costal cell are 

 inconstant even in the same species and even in the same specimen. 



Aufidus spectahilis, sp. nov. (PI. vii, figs. 5, 5a.) 



Head, pronotum, and scutellum ochraceous ; a transverse spot 

 at apex of vertex, a broad fascia between e^'es, and a broad basal 

 fascia to pronotum black ; bod}' beneath and legs ochraceous, 

 basal half of face black, anterior tibise longitudinally streaked 

 with black, tarsi more or less piceous ; abdomen above testaceous ; 

 tegmina with the basal third ochraceous and opaque, this area 

 outwardly margined by a transverse black fascia and containing a 

 black streak on upper claval margin with the lower basal margin 

 of the clavus also black, remaining area of tegmina hyaline with 

 apical ochraceous suffusions, veins alternatel}' ochraceous or pice- 

 ous, costal area ochraceous ; wings hyaline, palely ochraceous on 

 basal area, the veins pale- fuscous ; vertex with a fine central 

 longitudinal carination, and with a transverse impression near 

 middle ; pronotum with a central longitudinal sulcation not reaching 

 the anterior margin, the posterior margin slightly emarginate ; face 

 globose, laterally compressed, centrally longitudinally sulcate on 

 disk, costal cell with three or four small cells marked off by trans- 

 verse veins.

Aufidus papuauiis, sp. nov.

 margin narrowly and the basal margin broadl}^ black ; pronotum 



I Kirkaldy says this genus is more allied to Polychestophyes, of which the typi- 

 cal species is referred to " pi. xxxiii, figs. 12 and 13," but uo such illustration can 

 be traced.
