When defining the tribe Pamborini Dr. Horn said the pro- 

 thorax has " a setigerous puncture at middle of sides and another 

 near the hind angle."! This observation is accurate for the 

 posterior puncture, but otherwise only applies to P. guerini, P. 

 brisbanensis, and P. pradieri; P. guerini has sometimes a second 

 setigerous puncture about half-way between the one at widest 

 part and the anterior angle. In P. macleayi the number of 

 marginal setse on the anterior part of the sides varies; four speci- 

 mens are before me (all from Dunoon on the Richmond River, 

 N.S.W.); one of these (9) has only one setigerous puncture at 

 the widest part on each side; the other three (9 ^j c? 1) have the 

 anterior part of the prothorax with two widely placed setigerous 

 punctures on one side and three on the other (the distance 

 between these punctures shows that the presence of the extra 

 punctures is not due to the duplication of the ordinary single 

 puncture, though the duplication of such punctures is common 

 throughout the family Carabidse). P. alternans, P. morbillosuSy 

 P. viridis and P. opacns have always a puncture at the widest 

 part, and in addition several others forward from it. In Pam- 

 borus the apex of the abdomen is truncate in the ^ and rounded 

 in the 9; the sexes are thus readily distinguished from one 

 another. The species of Pamborus are found in the coastal dis- 

 tricts of Eastern Australia, from about the Shoalhaven River in 

 the south to Cairns in the north; P. viridis extends inland in 

 New South Wales to the Canoblas Mountains near Orange, and to 

 Coonabarabran. 



* Callimosoma, gen. ined., was proposed by Hope for Pamborus gueri 

 but has not been adopted.
