tubercle beiiecatli the first segment. Epipygiuin broadly truncate 

 at the apex, punctured, svith delicate, short, longitudinal striae 

 near the apex. The aculeus of the hypopygium does not extend 

 much be3^ond the epipygium. Black, with greyish-white pubes- 

 cence. Apical half of the mandibles and the legs piceous. 

 Length 1 1 mm.

The head and prothorax of a female pinned with this resemble 

 those parts in other species of the genus. 



Genus Aelurus Klug. 



Aelurus Klug, Physik.Abh. Akad.Wiss. Berlin, 1840, p.42, 1842 

 (nee Aehirns Sm.). 



(J. Antennae long and slender; head more or less narrowed 

 behind the eyes; mandibles bidentate; labium short, labial palpi 

 four-jointed, the first joint much the longest; maxilla small, galea 

 subtruncate at the apex and not divided; maxillary palpi six- 

 jointed, the apical joints filiform, very long and slender, the three 

 basal joints short and stouter, the first extremely short. Labrum 

 transverse, short. The division of the tirst cubital cell is marked 

 by a scar only, and the third cubital cell is not much narrowed 

 along the radial nervure. 



9. Head nearly rectangular; antennae thick; mandiljles lai-ge, 

 not bidentate ; abdomen cylindrical. Tarsal ungues simple. 

 Ashmead gives the maxillary palpi as four-jointed. 



I have not been able to dissect a female, nor does Klug give 

 any details as to the mouth-parts. The two Australian species 

 which I assign to this genus correspond well with the uiale of 

 Ael. clypeatas^ figured by Klug, in mouth-parts and neuration, and 

 are very different from the Australian species assigned to Aelurus 

 by Westwood and ^-^imth {Tacky no my ia). I have separated the 

 genus Leptnirone from Aelurus on account c>f the narrowing of 

 the third cubital cell along the radial nervure. Buttle/, iiafuhis 

 Klug, is the type of the genus, not Ael. chj'peatui< ; and the 

 neuration may possibly differ. 



Type ApX. nasufns Klug (Brazil).
