coarsely transversely striate, as in the 8, and the node has

Koolpinyah, Northern Territory, 6/4/1915 (Hill). 
Types in the British Museum. 
Dr. Forel has seen specimens of the 8 %, and confirms my 
identification of the subspecies. 
Subfamily IIT. Myruzcrv#, Lep. 
Meranoplus aureolus, sp. n. 
%. Length 2°2 mm. 
Head, thorax, and pedicel dark chestnut-brown ; gaster 
bright orange; mandibles, legs, and antenne intermediate in 
colour between head and gaster. 
Mandibles 4-dentate. Anterior portion of clypeus hollowed 
out, so as to form two carine at each side, ending in two 
teeth at anterior border; the posterior portion flattened. 
Head very slightly broader than long, broadest at occiput, 
narrowed in front. Antennal scrobes extend just beyond the 
eyes, which are placed well behind the middle of sides. 
First joint of club of antennz equals the following two 
together. Occipital border widely emarginate. Frontal 
area distinct, crescent-shaped, shining. 
Promesonotum broader than long; the lateral festoon is 
fairly straight for the anterior two-thirds, ending in three 
pointed projections, the second longest, and the third pair 
encireling the node. Shoulders of pronotum with a trian- 
gular projection turned forwards. Epinotum sloping, armed 
with two long, narrow, pointed spines. 
Node slightly broader than long, somewhat wider in front, 
the anterior border rounded ; in profile the anterior border is 
straight. 
Gaster cordate. 
Mandibles striate, clypeus with longitudinal ridges. 
Head: anterior quarter with longitudinal ridges which 
gradually become reticulations until when the occiput is 
reached the sculpture consists of coarse reticulate punctures, 
shining at the bottom. 
Promesonotum sculptured similarly to the occiput, as is 
also the node, but in the latter the punctures are more 
elongate. 
Gaster subopaque, with a fine reticulate ground-sculpture.
