accords with Cerylon, in close proximity to which Erichson has 

 placed the genus, that this discrepancy need not, for the present 

 at least, necessitate the generic separation of the two insects. In 

 addition to Erichson's description, the following generic characters 

 (most of them the same as in Cerylon) may be noticed in D. Fryi : — 

 Eyes narrow, transverse, scarcely prominent; external maxillary 

 lobe long and very slender, ciliated at the apex (inner lobe not 

 seen) ; maxillary palpi short, the first joint very small, the second 

 greatly enlarged, the third siibcyhndrical, the fourth minute, acicu- 

 late ; the labial palpi mth the second joint enlarged, the third 

 shortly conical ; mandibles bidentate at their extremity ; mentum 

 small, quadrate^ labium rounded anteriorly ; tarsi very short, the 

 three basal joints oblique, and hairy beneath. 



Glyptolopus [Colydiidae]. 

 Erichson, Natur. der Ins. Deutschl. iii. p. 292. 



Glyptolopus histeroides. (PI. VIII. fig. 5.) 



G, late ovatus, piceus ; prothorace elytrisque rugoso-costatis. 



Hab. Brazil (Rio). 



Broadly ovate, pitchy-black; head coarsely punctured, small, ver- 

 tical, scarcely visible above, narrowed below the eyes ; antennae twelve- 

 jointed, the first large, incrassated, and uncovered at its insertion, the 

 second short, not thicker than the third, the remainder becoming 

 gradually stouter to the tenth and eleventh, the last small, closely 

 enveloped in long silky hairs; prothorax semicircular^ very convex, 

 vaulted above and emarginate anteriorly, the centre with a broad longi- 

 tudinal groove, and a stout interrupted costa on each side, the lateral 

 margin strongly produced, the intervals coarsely punctured ; scutellum 

 triangular ; elytra as broad as the prothorax at the base, but not con- 

 tinuous with it above, the sides rounded and gradually decreasing pos- 

 teriorly, with five strong rugose costse on each, the intervals coarsely 

 punctato-granulate ; all the coxse distant, tibiae fusiform, strongly 

 fluted, not spm'red, tarsi short ; prostemum very strongly keeled, pro- 

 duced behind, and received in a notch of the mesosternum ; first abdo- 

 minal segment nearly as large as the rest together; body beneath 

 coarsely punctured. Length 2 lines. 



The few characters which Erichson has given of this genus, its 

 very peculiar habit (resembling an OntJiophilus), combined with the 

 acicular palpi of the Ceryloninae, and its habitat of Brazil, would 

 seem to leave no doubt that the insect described above is correctly 

 referred to Glyptolopus. The antennae, however, are certainly 

 twelve-jointed, while Glyptolopris is said to have onlj- eleven. Has
