332 MEMOIRS ON THE COLEOPTERA 



represent the true pusillus Kirby. In these Monmouth specimens 

 the elytral apices are broadly rounded, with scarcely even a trace 

 in any one of them of the narrow oblique truncature of obsoletus. 

 It only remains, therefore, to designate obsoletus, obliqiius and other 

 similar forms, as detailed further on, now figuring under Acanthocinus 



where they never really belonged, the thoracic processes being 

 spinose and not dentiform and noticeably more posterior in position 



by the name Graphisums Kirby and to restore the name Uro- 

 gr aphis Horn to triangulifera, fasciata and related species, as sug- 

 gested above.* 



The genus Urographis is composed at present of a very limited 

 number of species, all of the Atlantic regions and distinguished 

 from any of the more typically Acanthocinid genera which follow, 

 by the shorter antennae, rather less basal position of the thoracic 

 prominences, which are dentiform rather than spiniform and by 

 the presence of erect sparse black hairs on the elytra. The three 

 species and one subspecies in my cabinet may be outlined as follows: 



Last dorsal segment ( 9 ) very long, gradually finely pointed, convex and 

 with a dorsal stria basally, the fifth ventral of the female greatly 

 prolonged into a tube-like process, which is very deeply and angularly 



* There are, however, some points that I fail to comprehend fully in this connection. 

 Dr. Horn (1. c.) states that Graphisurus, as represented by biguttatus Lee. (pusillus 

 Kirby) is in all respects a Lepturges, in which the thoracic spine is at a distance from 

 the base agreeing with my identification as above, the female with an ovipositor 

 about a third as long as the body, also agreeing passably well and having sparsely 

 placed erect hairs on the elytra. This last statement is completely at variance with my 

 determination from the Monmouth specimens, and is not supported by LeConte's 

 definition of biguttatus or Kirby's description of pusillus, where no erect hairs are 

 mentioned; and again, through the association of the former by LeConte with sym- 

 metricus and other true Lepturgids, an absence of erect hairs might be inferred to be 

 still more likely. Then, on the other hand, LeConte places biguttatus with sym- 

 metricus and others, having an acutely angulate mesosternum. In my interpretation 

 of pusillus, which is quite certainly not Leiopus biguttatus Lee., the middle coxa are 

 well separated, the mesosternum not angulate but broadly obtuse, and there are no 

 vestiges of erect hairs on the elytra, the conditions throughout being exactly similar to 

 those of obliquus Lee. I think that my interpretation of pusillus, through the Mon- 

 mouth specimens, is correct, and as LeConte's biguttatus is surely something else 

 I formerly had an example of Urographis hebes under this name in my collection, 

 which could not be true because of the broadly truncate elytra; widely separated 

 middle coxae and short antennce, which according to Horn has erect hairs, rounded 

 elytral tips and narrowly separated middle coxae, I have not seen it, and the name 

 Ceratographis given it by Gahan is probably warranted; but I have nevertheless 

 retained the name Urographis, because of certain doubts regarding the generic 

 identity of Ceratographis biguttata and Urographis fasciata.
