Fabr. also fits that given for dorsalis Burm. The specimens 

 which I have seen labeled "dorsalis" were determined as such 

 by the late Mr. Otto Heidemann, but I am unable to distin- 

 guish them from sermtus. W. L. Distant* states, "I have 

 with Stal been unable to identify this species (dorsalis) ; it 

 probably represents one of the preceding Mexican species; but 

 the description is too slight for any accurate decision." 



This paper is based upon specimens in the United States 

 National Museum which had been previously determined by 

 Messrs. P. R. Uhler, Otto Heidemann and R. M. Reuter, also 

 upon considerable previously undetermined material, and in- 

 cludes one new species the type of which is in the collection 

 of the U. S. National Museum. I am indebted to Mr. J. R. 

 de la Torre Bueno for the privilege of examining a small col- 

 lection of specimens in this genus, representing six species. 



Genus HARMOSTES Burm. 



Harmostcs Burm., Handbuch der Ent., 1835. 



The following is a translation by the author of the original 

 description by Burmeister: 



Resembles Corizus Fall., Hahn, but differing from it in hav- 

 ing hind femora with pronounced spines. Antennae two-thirds 

 as long as body, the first joint short, stout, and the two fol- 

 lowing delicate and of equal length, the fourth shorter than the 

 preceding one and swollen at the apex. Ocelli near eyes. 

 Thorax with raised curved margins, also always sloping. Front 

 legs normal, the hind legs longer, with femora very thick, under 

 side spiny. 



A redescription of the genus is not at all necessary. Dallas 

 gives as generic characters, besides those contained in the above 

 description : breast furrowed longitudinally for the reception 

 of the rostrum and rostrum reaching or passing the inter- 

 mediate coxae, with its third joint as long as or longer than 

 the fourth.
