 brown; caudal limbs burnt umber becoming seal-brown on the

All of the specimens before us appear to have been immersed in 

 alcohol at some time, and in consequence the color description is not

as satisfactory as could be desired. In nearly all of the specimens 

 the scales have been almost completely abraded and in but one 

 specimen is there enough left to give an idea of the mass coloration 

 of the scales. 



Distribution. — With all the known material of this species before 

 us, we can only give its distribution as the Cape Region of Lower 

 California. San Jose del Cabo and Cape St. Lucas are the localities. 



Synonymy. — Originally described and for years known only from 

 two typical females, the acquisition of males of the allied boreah 

 enabled Scudder to remove the species from Mogoplistes, in which he 

 had erroneously placed it at the time of the original description. 

 Unfortunately, he placed it in Ectatoderus Guerin, a genus which has 

 no apparent tegmina in the male and an immensely long pronotum 

 in the same sex. In consequence we have been compelled to erect 

 the genus Hoplosphyrum to receive the three forms here placed in it.
