ferrugineo-ciliatis ; capite crasse rugulose punctulato, liiiea 



mediana longitudinali elevata obsciira iiistructo ; protlioiace 



qiiain longioii vix latiori, sat ciebre sat crasse confuse rugato 



et sparsim punctulato, disco tuberculis 2 parvis munito, 



lateribus antice tuberculo parvo armatis ; elytris sat grosse 



punctulatis, apice sinuato-truncatis, spina suturali apicali 



armatis, basin versus tuberculatis, tuberculis majoribus in 



utroque elytro juxta basin seriatim positis, ex his tuberculo

medio dente magno armatis. [Long. 12, lat. 4 lines. 



It is possible that the type of this species is abraded, but I do 



not hesitate to describe it as its characters of sculpture and of sex 



are extremely remarkable. The dense pilosity on the tibise and 



the toothed front femora and tibiae of the male are not found, I 



think, in any other described Symj^hiletes, except the toothed 



front tibiae which are attributed to S. neglectus — a very difterent 



species. The tubercles on the front part of the elytra consist of 



three rows on each, in which those of the sutural and external 



ones are small, while those of the middle row are larger, especially 



the middle one of that row, which is very large (being about the 



same size as the tubercle at the base of the elytra in Demonassa 



dichotoma, Newm.). The elytra are punctured very much as in 



D. dichotoma except that their puncturation is scarcely so coarse 



in front and is less enfeebled behind. 



This species bears a good deal of general resemblance to S. 

 fumatus^ Pasc, but differs from it by its remarkable sexual 

 characters, by its more elongate protliorax, the very much greater 

 size of one of the elytral tubercles, the longer 3rd joint of its 

 antennae (in the male), &c., &c. Mr. Pascoe says that the pro- 

 thorax of S. fioinatus is longer than broad, a statement clearly not 

 founded on measurement, which shows the prothorax distinctly 

 wider than long, though to a casual glance it appears elongate.
