been observed hitherto; they are entirely wanting in planipennis 

 and maritimus, very feeble in honstoni and again obsolete in ceneo- 

 piceus, showing that these species are not so closely associable with 

 pedicular itts and troglodytes as formerly supposed. They were not 

 discovered by the writer until the descriptions of the species given 

 above had been long under way, and, as the species having like 

 sexual characters happen to be brought into juxtaposition by use 

 of other more general characters, it is not necessary to recast the 

 table on that score. As another interesting fact, pointing toward 

 Discoderus, it should be stated that in riparius the middle tarsi of 

 the male are completely undilated and very slender, though bearing 

 beneath the usual two series of squamules. 



Beauvoisi Dej., is of a common Central American type and has 

 occurred so far only in the West Indies. The following species is 

 decidedly doubtful as to generic relationship, so far as published 

 characters serve to show: 



S. breviusculus Horn Oval, slightly oblong, robust, piceous, the 

 legs pale; surface feebly shining, with distinct bronze lustre; head punc- 

 tulate, rugulose at the sides above the eyes; prothorax broad, the apex 

 and base equal, the sides rather strongly arcuate; basal angles broadly 

 rounded, the base feebly emarginate at the middle; surface convex, 

 the sides slightly depressed posteriorly, more shining at the middle, 

 finely, transversely wrinkled, in front finely punctulate, at base and sides 

 densely punctate and opaque; elytra not wider than the prothorax, 

 scarcely a third longer than wide, the sides moderately arcuate, the apex 

 scarcely at all sinuate, moderately deeply but finely striate, the inter- 

 vals flat and irregularly but finely, biseriately punctulate and pubescent; 

 serial punctures very fine and indistinct; eighth stria distant from the 

 margin; body beneath feebly shining, the abdomen sparsely punctate 

 and with short pubescence; legs testaceous, the middle and posterior 

 tibiae slightly arcuate. Length 6.5 mm. Indian Territory (now Okla- 

 homa), Fort Cobb. 



I have seen no representative of this species, but it is my opinion 

 at present that it, together with curvipes, arcuatus and crassiusculus, 

 should be separated as a distinct genus, coming between Seleno- 

 phorns and Discoderus. 



Selenalius n. gen. 



The general habitus of this genus is quite distinct from that 

 observable elsewhere in the Selenophorini, due to the peculiar shape 

 of the prothorax, which recalls that of Glanodes. Presumably not
