CHARACTERS OF H. REDIVIVUS AND VAR. 71 



1). LECONTii. — Ci7iereus, alis catiddque concoloribus ; infra 

 dilutior, gula albldd, strigis maxillaribus fuscis, ventre crissoque 

 sensim ochraceis. 



This form, with the size and proportions substantially the same as those 

 of redicii'Ms proper, diifers very notably in the pallor of all the coloration, 

 being in fact a bleached desert race. Excepting the slight maxillary streaks, 

 there are no decided markings anywhere ; and the change from the pale 

 ash of the general under parts to the brownish-yellow of the lower belly 

 and crissum is very gradual. 



The characters of the typical form are subjoined for comparison.*
