^Eolothynnus crenulatus, sp. n. (Plate XXXI. fig. 8, J •) 



c? . Clypeus moderately convex, advanced and truncate at the 

 apex, finely and shallowly punctured. Maxillary palpi rather 

 stout, the basal joint short the apical lobe of the galea beyond 

 the dividing-line large and rounded at the apex. Antennae as 

 long as the thorax without the median segment, of even thickness 

 throughout, inserted a little nearer to each other than to the 

 eyes. Head finely and closely punctured, no broader than the 

 pronotum ; the front and clypeus thinly clothed with long grey 

 pubescence. Thorax rather closely punctured, sparsely on the 

 scutellum, very closely on the mesopleurse ; pronotum only slightly 

 narrowed anteriorly, the anterior margin slightly raised and 

 almost straight ; mesonotum less than twice as long as the pro- 

 notum ; scutellum broadly truncate at the apex. Median segment 

 finely and closely punctured, very short, steeply sloped posteriorly 

 but not truncate, the sides clothed with white pubescence ; an 

 almost obsolete impressed longitudinal line from the base not 

 reaching the middle. Abdomen longer than the head and thorax 

 combined, the sides nearly parallel ; segments strongly constricted 

 at the base ; the sixth ventral segment with a spine on each side 

 at the apical angles ; the dorsal segments closely punctured ; the 

 ventral segments punctured-rugose, finely longitudinally striated 

 at the extreme base. Hypopygium broad, tridentate, the lateral 

 spines very short, the apical spine much longer. 



Black ; the mandibles at the base, the apex of the clypeus, and 

 two minute spots between the antennae whitish yellow, a large 

 quadrate spot on the mesonotum, the tegulae and a curved line 

 above them, a spot on the mesopleurae below the anterior wings, 

 a broad transverse band on the scutellum, and a small spot at 

 each of the anterior angles, the postscutellum, a broad transverse 

 band interrupted in the middle on each of the five basal dorsal 

 abdominal segments, narrowest on the first, a spot on each side of 

 the sixth segment, and the apical half of the anterior and inter- 

 mediate femora beneath, yellow ; tibiae and tarsi f usco-ferruginous. 

 "Wings hyaline, nervures black, the stigma f usco-ferruginous. 



The second cubital cell is much longer on the radial nervure 

 than the third, and receives the first recurrent nervure beyond 

 three-quarters from the base, the second recurrent nervure is 

 received near the base of the third cubital cell. 



Length 12 mm., exp. of wings 20 mm. 



Hub. Hermannsburg, Central Australia (H. J. Hillier). April. 



Belongs to the cerceroides group, but is not very near any 

 described species.

 truncate at the apex, finely punctured, almost smooth in the 

 middle. Antennae rather short, of even thickness throughout. 

 Head finely and closely punctured, thinly clothed with white
