MR. H. N. RIDLEY ON THE 
medium oblique angustato, creberrime subtiliter puuctulato ; 
elytris thoracis basi perparum latioribus, subtiliter striato-punc- 
tatis, interstitiis parce subtilius punctatis, parce pubescentibus, 
seriatim squamulato-setosis ; autennis perlib usque sordide tes- 
taceis. 
Long. 2 millim. 
Head distinctly visible from above ; concave in front in one sex. 
Eyes coarsely granular, widely separated above, but very slightly 
separated below. Antennae testaceous ; funiculus 6-jointed (or 
possibly 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 punctured, 
the intervals between the punctures about equal to the diameter 
of the punctures ; sparsely pubescent, the hairs at the front 
margin slightly thickened. The striae 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, w r ith four or five small obtuse teeth on the 
outer side, and two larger ones, one at one third from the apex, 
the other apical. Tarsi slender. 
This insect agrees in the majority of its characters with Pyc- 
nartlirum gracile , Eichh. (Mem. Soc. R. d. Sci. Liege, viii. 1878, 
p. 104). The anterior tibiae are, however, evidently different : 
“ tibiae anteriores apice extus rotundatae.” The structure of the 
antennae appears to be the same, but the club is ovate and not 
acuminate. The elytra are punctate-striate and not crenate- 
striate, and the punctures are round and not subquadrate, &c. 
It appears to be related to Cnesinus , 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 Residency. — H. Ab P.J 
Platypus parallelus, F. 
Two examples of this Brazilian species. 
* The joints after the first are so confused that even with the antenna 
mounted in balsam I am not quite certain of their number.
