tate toward base, the punctures becoming gradually very minute und rather 

 dense toward apex. Prosternum before the coxae densely and finely punctato- 

 scabrous and clothed densely with long fine pubescence. Mesosternal process 

 very narrow, not extending to the apices of the coxae, and separated from the 

 short, obtusely CTispifonn process of the metasternum by an appreciable in- 

 terval. Mesosternal epinieron with a posterior fringe of long dense hairs as in 

 Sapintus. Legs rather long, very slender. Length 3.0 mm.; width 1.05 mm. 



Virginia (Fort Monroe). 



This is one of the most conspicuous and interesting anthicides 

 of our fauna. I owe two specimens to the kindness of Messrs. 

 Hubbard and Schwarz. 



LAPPrS n. gen. 



The species composing this genus have heretofore been re- 

 garded as a simple section of Anthicus, but the structure of the 

 mesosternum and prothorax, as well as their peculiar general habi- 

 tus, demands a separation of them from that unwieldy complex. 

 The}^ are very numerous in the United States, especially in the 

 arid southwestern country, as shown by the results of recent 

 skillful collecting in those regions. 



This genus differs from the others more closel}' allied, in the 

 great development of the fourth joint of the maxillarj' palpi, and 

 the long tactile setre, which are so conspicuous a feature in* Mal- 

 porus, are completely wanting; the punctuation is very fine and 

 dense as a rule, also in striking contrast to that genus. In re- 

 gard to the oedeagus, I have seen no specimen with the apparatus 

 sufficiently protruded for examination, and I have not had 

 enough time or duplicate material to make dissections, but it 

 is doubtless somewhat complex in structure. 



It is scarcely possible that Lappus can be identical with the 

 South American Ischyropalpus of LaFerte, for neither Lapijus 

 obscurus nor L. shirmi {elegans) seems to have suggested to the 

 author an alliance with Ischyropaljjas 2)erplexus (Mon., p. 142 j, 

 but in case obscurus and perjjleccus should prove to be congeneric, 

 there is no reason wh}' the name Ischja'opalpus should not be re- 

 stricted to either sericans or trigonocephalus (1. c, pp. 143, 146), 

 as the first is probably, and the second certainl}^, generically dif- 

 ferent from per2:)lexus. 



Our species, so far as known, may be conveniently separated
