A variety of this occurs at Mackay. The typical form 

 has the tergites black, the second sometimes stained with 

 fusco-ferruginons ; in the Mackay form the three basal 

 tergites at least are yellowish brown ; the legs are black 

 in the type, but in the Mackay form the fore legs entirely 

 and parts of the intermediate and hind legs are testaceous 

 brown. The second suture in this species is straight and 

 crenulated. As the colour differences appear to be con- 

 stant. I propose for the Mackay form the name /. flaviceps 

 snbspec. machayensis, subspec. n. 



Hab. N. Queensland, Mackay (Turner), October and 

 November 1899. 



The locality given for the type is Australia, but it prob- 

 ably came from the south-eastern portion of the continent. 



Ipobracon fraterculus, sp. n. 



$. Nigra; capite flavo; segmentis dorsalibus duobus basalibus 

 ochraceis, quarto sequentibusque apice angustissime albido- 

 marginatis; ventre albido, nigro-maculato ; tibiis tarsisque anticis 

 brunneo-ferrugineis ; tegulis testaceis; ali.s fusco-hyalinis, venis 

 fuscis, stigmate pallide brunneo-flavescente. 



Long. 10 mm. ; terebrae long. 9 mm. 



£. Face subopaque, minutely punctured; the antennal tubercles 

 prominent ; front and vertex smooth and shining, a .shallow depres- 

 sion between the anterior ocellus and the base of the antennae; 

 scape more than twice as long as broad, cylindrical; head nut 

 narrowed behind the eyes. Thorax and median segment smooth 

 and shining; the parapsidal furrows distinct, but shallow. First 

 tergite smooth, longer than the apical breadth, the lateral grooves 

 narrow and not margined externally; the raised portion with an 

 indistinct median longitudinal carina and with distinct lateral 

 carinae. Second tergite short, broader at the base than long, 

 widened to the apex; the basal raised area large, triangular, mar- 

 gined at the sides by broad and rather shallow grooves in which 

 are a few oblique striae; the lateral grooves of the segmenl very 

 narrow, but extending to (he apical angles; second suture almost 

 straight, crenulated. The areas at the anterior angles of the third 

 tergite are rather large. Recurrent nervure almost interstitial; 

 first abscissa of the cubitus straight.
