dense punctuation of the gaster is distinctly finer than that of 

 other portions of the body. Hairs golden -yellow, erect^ 

 moderately long, not abundant, rather obtuse, most conspicu- 

 ous on the upper-surface of the head, epinotum, and gaster^ 

 Pubescence yellow, very sparse, and rather long, distinct on 

 the head, especially on the clypeus, gaster, and appendages. 

 Tips and flexor surfaces of femora with a few long, erect hairs. 

 Black : apical portions of mandibles deep-red : each gastric- 

 segment with a conspicuous dull-golden band on its posterior 

 border. 



Described from six workers, five from the Musgrave- 

 Ranges and one from Moorilyanna. This beautiful species is^ 

 readily distinguished by its peculiar head, very opaque surface,, 

 and the unusual banding of the gaster. 



26. Camponotus (Myrmosphincta [? ]) whitei, n. sp. 

 PI. Ixvi., fig. 8. 



Worker (minor ['^.]). — Length, 4'5-5 mm. 



Head trapezoidal, deepest in the frontal region, a little 

 longer than broad, slightly broader behind than in front, with 

 straight sides and feebly concave posterior border. Eyes 

 moderately large, very convex, nearly circular, distinctly^ 

 behind the median transvers^e diameter of the head. Man- 

 dibles with slightly convex external borders and oblique, 

 6-toothed apices. Clypeus strongly carinate, rather convex, 

 with entire anterior border, subangularly produced in the 

 middle. Frontal area rather large, triangular ; frontal groove 

 lacking ; frontal carinae approximated in front, curved out- 

 ward in the middle, and again approximated behind. An- 

 tennae rather long and stout ; scapes surpassing the posterior 

 border of the head by fully two-fifths their length. Thorax 

 rather long, nearly as broad as the head through the pronotum, , 

 which is flattened above, bluntly marginate anteriorly, and 

 seen from above a little broader than long. Promesonotal 

 suture pronounced. There is a deep, saddle-like impression in 

 the region of the mesonotal suture, which is obsolete, and the 

 thorax is also laterally compressed in this region. The 

 epinotum is very convex and rounded, and resembles somewhat 

 that of a Dolichoderus, but in profile the base passes without- 

 an angle into the vertical, slightly concave declivity of about 

 the same length. Petiole nodiform, seen from above regularly, 

 transversely elliptical, and about twice as broad as long, in 

 profile less than twice as high as long, the node with three 

 surfaces, a short vertical anterior, a horizontal rounded dor- 

 sal, and a vertical posterior surface. Gaster rather small, 

 broadly elliptical. Tibiae cylindrical.
