Black ; a spot on each side at the posterior angles of the pro- 

 not una, a transverse band on the first dorsal abdominal segment 

 above the truncation, a spot on each side of the second segment, 

 a transverse band interrupted in the middle on the third segment 

 and a transverse spot on each side of the fourth, pale yellow. 

 Anterior tibia? fusco-ferruginous beneath. 



Length 17 mm. 



Hab. South Perth, W. A. (H. M. Giles). 



Zaspilothynnus cxelandi, sp. n. (Plate XXXI. figs. 14 <^ , 

 15?.) 



S . Glypeus large, very broadly truncate at the apex, almost 

 pointed at the base, punctured at the extreme base, elsewhere 

 finely longitudinally striated, with sparse punctures between 

 the stria?. Antennae as long as the thorax without the median 

 segment, of almost even thickness throughout. Head closely 

 punctured ; the interantennal prominence broadly rounded at the 

 apex and connected with the base of the clypeus by a very short 

 narrow carina. Thorax and median segment finely and closely 

 punctured, more sparsely on the scutellum and on the disc of the 

 mesonotum ; scutellum large and broadly rounded at the apex. 

 Median segment more than half as long as the scutellum on the 

 dorsal surface, then obliquely sloped and subconcave to the apex. 

 Abdomen sparsely punctured, shining, longer than the head, 

 thorax and median segment combined, tapering slightly at the 

 extremities ; the apical dorsal segment produced from the base into 

 a small, flat, longitudinally striated plate which is very feebly 

 emarginate at the apex. Sixth ventral segment with a spine on 

 each side at the apical angles. Hypopygium with a blunt spine 

 on each side at the basal angles, thence narrowly produced and 

 elongate to the base of apical spine, transversely striated above, 

 with a median longitudinal carina. 



Black ; the clypeus, the margins of the eyes interrupted at the 

 summit, the band on the outer margin continued along the 

 posterior margin of the head, the interantennal prominence 

 narrowly continued to the anterior ocellus, the mandibles (except 

 at the apex), the margins of the pronotum, a large spot on the 

 disc of the mesonotum, the tegula? and a longitudinal line above 

 them, the whole front of the mesopleura?, a large spot before the 

 intermediate coxa?, the middle of the scutellum very broadly and 

 a spot at each of its anterior angles, the postscutellum, the median 

 segment with a longitudinal black band on each side, a broad 

 transverse band on each of the six basal abdominal segments 

 interrupted in the middle on the dorsal surface, the prosternum, 

 the apex of the mesosternum, the coxa?, the femora beneath and 

 the tibia? above, yellow. Wings hyaline, nervures black. The 

 labrum is pale testaceous, shallowly emarginate at the apex. 



Length 13-20 mm. 



$ . Mandibles long, falcate, acute at the apex ; the clypeus 

 without a carina. Head smooth and shining, with a few scattered
