The insect on which this genus is founded is an extremely 

 -perplexing one. I received it from Central Australia many 

 years ago and have never been able to make up my mind where 

 in the Tenebrionidm to place it. Most of its characters associate 

 it with the " Tribes " that form the first " Cohort" of the second 

 " Section" in M. Lacordaire's arrangement, but I have felt great 

 difficulty in placing it among them on account of its tarsi pube- 

 scent beneath and the structure of its prosternum which is such 

 that the front margin of the front coxse is scarcely further from 

 the front margin of the prosternum than the hindmargin of the 

 same coxa? is from the hindmargin of the prosternum. Lately I 

 have submitted an example to that accomplished specialist in the 

 Tenebrionidce Mr. G. C. Champion and with his usual courtesy 

 he has written me his opinion that it ought to be placed in the 

 "Cohort" to which I was disposed to refer it, pointing out a 

 character confirming it in this position, the importance of which 

 seems to have escaped the attention of M. Lacordaire ; viz., the 

 absence of a coriaceous hindmargin to the third and fourth 

 ventral segments. Mr. Champion thinks it in some respects 

 allied to Asida (belonging to a "Tribe" not hitherto known as 

 Australian) though of entirely different facies, and also notes its 

 relationship to JVyctojjoris, — near which (and therefore, according 

 to M. Lacordaire's arrangement, in the Tribe Scaurides) I had 

 myself been inclined to think it seemed least out of place. I
