Ael. ruficrus, n.sp. 



(J. Clypeus with a very short carina at the base, branching 

 broadly and shortly; the apical portion smooth and shining, not 

 much produced at the apex, the apical margin slightly emarginate 

 at the sides before the angles, which are produced into short, 

 blunt spines. Head densely punctured, with an interantennal 

 carina, rounded at the apex; slightl}' narrowed behind the eyes. 

 Prothorax depressed, the anterior margin raised, very closely and 

 minutely punctured. Mesothorax and scutellum punctured, the 

 scutellum rather long, narrowly truncate at the apex. Median 

 segment delicatel}^ reticulate, almost smooth at the base, rounded. 

 Abdomen elongate, subcylindrical, shining, with shallow, scattered 

 punctures; segments 2-5 with "a transverse line near the base. 

 Epipygium strongly punctured, smooth at the apex and sub- 

 truncate. Hypopj'^gium rounded and ciliated. Black ; w^ith 

 fulvous pubescence on the sides of the head and median segment; 

 the mandibles, the apical portion of the clypeus, the legs, the 

 tegulse, and the four basal segments of the abdomen bright rufo- 

 testaceous. Wings pale flavo-hyaline, nervures black, testaceous 

 at the base. Length 15-17 mm. 



/?a6. — Kenthurst, N.S.W. Type in Coll. Froggatt. 



Subgenus Lepteirone, n.subgen. 



^. Differs from Aelurus in the neuration, the third cubital cell 

 being much narrowed along the radial nervure. The clypeus has 

 either a carina from the base ending in a tubercle before the 

 apex, or an elevated triangular area from the base, suddenly 

 ceasing before the apex, leaving the apex depressed below the 

 basal portion. 



The female resembles that of Eirone and Aelurns in form, but 

 I have been unable to dissect specimens. 



The insects are slenderer than in Eirone ((J), in this point 

 resembling the typical S. American Aeluri. 



Type L. ru/opictus Sm. 



This group occurs also in S. America, lltynnus nigrofasciatus 

 Sm., belonging to it.
