46 MR. R. E. TURNER ON 



allied walheri Turn, differs in the deeply emarginate apex of the 

 dorsal plate of the pygidium. These three species are very 

 closely allied and probably do not occur together. The only 

 other species of Pogonothynnus which I took at Yallingup was 

 fenestrates Sm., of which I obtained two males and a female. In 

 one male the process of the hypopygium is narrower than in 

 Perth specimens, in the other much broader, showing that too 

 much importance must not be attached to small variations in the 

 shape of the hypopygium. 



Oampylothynnus lundy^e, sp. n. (PL I. figs. 17, 18.) 



S . Flavus ; mandibulis apice, antennis, vertice fascia lata inter 

 oculos, antice per ocellos posticos ad basin antennarum producta, 

 fascia sub-ocello antico, pronoto fascia angusfca transversa, meso- 

 noto fasciis tribus longitudinalibus, scutello segmentoque mediano 

 fascia angusta longitudinali, mesosterno, segmentis dorsalibus 

 ventralibusqiie linea longitudinali mediana, tibiis supra, tarsisque 

 intermediis posticisque nigris ; alis hyalinis, venis nigris. 



5 . Flava ; mandibulis, fronte inter oculos ; segmentis dorsal- 

 ibus primo secundoque fascia transversa apicali, tertio, quarto 

 quintoque linea apicali in media dilatata, maculaque basali 

 utrinque, pygidio, femoribus supra, tarsisque posticis nigris. 



Long., tJ 23 mm. ; $ 14 mm. 



tf . Closely punctured, more finely on the abdomen than on 

 the thorax. Interantennal prominence very broadly rounded at 

 the apex, connected by a short carina with the base of the 

 clypeus, which is very broadly truncate at the apex. Pronotum 

 rather strongly produced at the anterior angles but not forming 

 tubercles. Apex of the scutellum raised above the level of the 

 postscutellum. Abdomen elongate, the sides nearly parallel ; 

 seventh dorsal segment not flattened or produced into a lamella ; 

 hypopygium with a spine on each side at the basal angles, thence 

 narrowly produced with converging sides and ending in a long 

 apical spine. The second transverse cubital nervure is nearer 

 to the second than to the first recurrent nervure. 



2 . Head shining, broader than long, very sparsely punctured, 

 with a short longitudinal frontal sulcus, three large punctures 

 apparently indicating the position of the ocelli. Thorax very 

 sparsely punctured ; pronotum twice as broad as long, with a 

 row of deep punctures along the anterior margin ; dorsal surface 

 of the median segment no longer than the scutellum. First 

 dorsal segment with a transverse carina at the apex, with a broad 

 groove before the carina ; second dorsal segment with three 

 strong carina?, which are separated by a very broad furrow from 

 the apical carina. Pygidium shining at the base, constricted 

 and marked with several arched carina? at the base of the oblique 

 posterior truncation, the surface of which is elongate ovate ; the 

 ventral plate slightly broadened and rounded beyond the apex of 

 the dorsal plate. Fifth ventral segment coarsely longitudinally
