I am very doubtful if Saussure's description can be intended 

 for this species. Smith's type was from Western Australia, and 

 specimens received from Mr. Giles and which I have compared 

 with the type are mated with the female described below. 



2 . Head not large, nearly twice as broad anteriorly as long, 

 strongly rounded at the posterior angles, shining and very 

 sparsely punctured, with a short frontal sulcus, the punctures 

 round the base of the antennae closer and piliferous. Thorax 

 much narrower than the head ; the pronotum less than twice as 

 broad anteriorly as long and half as broad again anteriorly as 

 posteriorly, the anterior and lateral margins with a sparse fringe 

 of long hairs, finely and sparsely punctured. Median segment 

 short, about the same length as the scutellum, strongly broadened 

 from the base, the posterior truncation almost vertical. First 

 dorsal abdominal segment divided into two almost equal parts, 

 the apical portion strongly depressed and smooth, the basal 

 portion raised and very sparsely punctured ; second segment with 

 four transverse carinae, including the raised apical margin, the 

 basal carina very low and often covered by the first segment, the 

 third high and separated from the apical margin by a broad 

 groove. Third and fourth segments with a raised curved mark 

 on each side before the apex, the apical margin depressed, the 

 raised portion punctured at the apex. Pygidium almost vertically 

 truncate, long and narrow, about three times as long as the 

 greatest breadth, a little broader towards the apex than at the 

 base, rounded at the apex, the dorsal plate as long as the ventral, 

 the basal portion with a median longitudinal carina and two 

 lower carinas converging at the base on each side. Fifth ventral 

 segment coarsely punctured in the middle at the apex. There is 

 an emargination and spine near the base of the intermediate 

 tibife beneath as in sitiens and trifidus. 



Pale luteous ; head f usco-f erruginous ; median segment, the apex 

 of the raised portions of the first, third, and fourth dorsal abdo- 

 minal segments, and the third carina on the second segment black. 



Length 6-7 mm. 



Hab. Claremont and Cottesloe, W. A. {H. M. Giles). 



The colour is very variable, the black in some specimens being 

 much more extensive. 



Females from the east coast answer rather better to Saussure's 

 description. The male is hardly distinguishable from the western 

 specimens.

I was evidently wrong in sinking this as a synonym of
