Artireriit regius. King. 



In the original description of this species the abdominal fovea 

 is not mentioned. Mr. Masters has sent two specimens for 

 examination both males and from Liverpool, one of which is 

 probably the cotype mentioned as being deposited in the 

 Macleay Museum. 



The abdominal fovea is confined to the basal segment, and is 

 bounded on each side of the middle by an oblique ridge, of 

 which the apices are separated fully twice the width of the 

 bases. The front femora are larger, and the middle femora 

 much larger, than the head. 



Articerus hreviceps. King. 



Mr. Masters has sent for examination a co-type of this species, 

 probably a female, and unfortunately with both antennae miss- 

 ing. In the original desci-iption the abdomen is not even men- 

 tioned ; its fovea is, for the genus, comparatively shallow, some- 

 what encroaching on middle of second segment, and with a wide 

 flattened oblique ridge on each side of the middle. The pro- 

 thoracic fovea is unvisually large, the punctures on each side 

 of and behind it coarse, but in front much finer. The base of 

 the head has a distinct longitudinal impression. The tibiae are 

 strongly (but, for the genus, moderately) infiated towards the 

 apex. 



Articerus aurifluus, Schfs. (Fig. 30). 



Mr. H. H. D. Grilfith has sent from Adelaide^ nine specimens 

 that appear to belong to this species. They have the antennae, 

 prothorax and abdomen (the clothing at the sides is remark- 

 able) as described, but the head is more rounded in front than 

 triangular, although from some directions it appears feebly 

 triangular. 



The hind tibiae of tlie male are narrow at the base, then 

 suddenly inflated and subparallel to near the apex, where they
