554 MR. H. N. RIDLEY ON THE 



medium oblique angustato, creberrime subtiliter punctulato ; 

 elytris thoracis basi perparum latioribus, subtiliter striato-puuc- 

 tatis, iuterrititiis parce subtilius puuctatis, parce pubescentibus, 

 seriatim squamulato-setosis ; autenuis pedibusque sordidc tes- 

 taceis. 



Long. 2 millim. 



Head distinctly visible I'rom above ; coucaveiu irout iu oue sex. 

 Eyes coarsely granular, widely separated above, but very slightly 

 separated below. Antennae testaceous ; funiculus G-jointed (or 

 possihly 7)*; the first large, subglobose; the following joints 

 very short and transverse, gradually increasing in width ; club 

 large, 3-jointed, oval, pubescent. The thorax has a well-defined 

 margin separating the under flanks. The surface (seen through 

 a microscope) is finely coriaceous, moderately finely 2)unctured, 

 the intervals between the punctures about equal to the diameter 

 of the punctures ; sj)arsely pubescent, the hairs at the Irout 

 margin slightly thickened. Tlie stripe of the elytra are lightly 

 impressed, but scarcely so on the disk ; the punctures in the striae 

 moderately fine and close together, the punctures on the inter- 

 stices rather smaller and moderately widely separated. Anterior 

 tibiae rather broad, wdth four or five small obtuse teeth on the 

 outer side, and two larger ones, one at oue third from the apex, 

 the other apical. Tarsi slender. 



This insect agrees iu the majority of its characters with Pyc- 

 narihrum gracile, Eichh. (Mem. Soc. R. d. Sci. Liege, viii. 1S78, 

 p. 104). The anterior tibiae are, iiowever, evidently different : 

 " tibite anterioi'es apice extus rotundatae." The structure of the 

 antennae appears to be the same, but the club is ovate and not 

 acuminate. The elytra are puuctate-striate and not crenate- 

 striate, and the punctures are round and not subquadrate, &c. 



It appears to be related to Gnesinus, Horn, but the anterior 

 coxae are not so widely separated. 



[It was bred from the bark of the endemic fig-tree, from a 

 specimen out of the garden of the liesidency. — II. H. It.'] 



Platypus parallelus, F. 



Two examples of this Brazilian species. 



* Tlio joints after the first are so conl'uticd that even with tlie antcnua 

 nioiink'd iu balsam I am not q\ate certain of their number.
