in the strias, which become somewhat obhterated towards the 

 sides. There is a row of impressed punctures along the basal half 

 of each lateral margin, and, a little way inside of them, another 

 row, with the punctures few in front, but getting closer towards 

 the apex, where are a few other punctures of the same character. 

 The fore tibiee are bluntly tridentate externally ; the intermediate 

 tibi^ have one external tooth rather long, obtuse, and laterally 

 compressed ; and all the tibice, but particularly the hinder, are 

 strongly ciliated with reddish hair. The distinct striation of the 

 elytra renders this species easily distinguishable. 



Since the foregoing was written, I have discovered in my 

 collection several species of Scaritideous Insects, which I have 

 no hesitation in referring to the genus Gnatlioxys, although they 

 do not quite agree with Mr. Westwood's description of that 

 genus. In general habit, in the peculiar character of the sculp- 

 tui'e of the elytra, in the convexity of the thorax, in the unarmed 

 mandibles, in the nientum without medial tooth, and in the 

 tridentate fore tibia;, these new species agree with the previously 

 described species of Gnatlioxys ; but ihej differ in having their 

 palpi securiform, while the mandibles in some are not acute at 

 the apex. In one species, however, which I have named tes- 

 selatus, while the palpi agree with Mr. Westwood's description 

 of the genus, there is a greater departure from the usual charac- 

 ter of the Scaritidce, and a nearer approach to the Feroniidce by 

 the genus Promecodems, than is exhibited in any other species. 

 But in truth they all so much resemble the species of Prcme- 

 coderus, that I had at first sight placed them with the insects 

 allied with Gneinacanthus.
