708 KEVISIONAL NOTES ON AUSTEALIAN CARABIDJ^, L, 



With my slight knowledge on the subject of chsetotaxy I feel 

 unable to place upon the different tactile setae any fixed taxono- 

 mic value, nor can I attribute to any of them among the Bii^artiti 

 the extreme importance which Dr. Sharp has given to the thoracic 

 setfe among the Hawaiian Carabidse. 



The Setigerous Punctures of the Anterior Femora and Posterior 



Goxce. 



(1) The anterior femoral setce. — The normal number of setiger- 

 ous punctures on the posterior face of the anterior femora in the 

 Bipartiti must be taken to be three, placed as follows : one very 

 near the trochanter on the middle of the posterior face of the 

 femora {basal seta); one near the lower edge varying in position 

 from about basal third to middle of length of femur {median seta) 

 — this seta would often be more accurately described as being on 

 the posterior edge of the lower face of the femur ; and one 

 towards the apex near lower edge, about the middle of the apical 

 sinuosity of the lower side of the femur {suhapical seta of lower 

 edge). When all three setfe are present the femur may be said 

 to be 3-setose; this is the case in Scarites, Geoscaptus, and Clivina. 

 The median and basal setae seem to be of universal occurrence 

 throughout the tribe (though I have not been able to distinguish 

 either of them in my unique specimens of Xeocarenum elongatum 

 and ^y. blackhurni). The presence or absence of the subapical 

 seta has an important taxonomic value in the typical Carenums; 

 I have never found it in a species of Xeocarenum, Carenidium, or 

 Neoscaphus, nor have I ever found it absent (except in Carenum
