 Ccedio differt prothorace postice baud bisinuato, scutello nullo. 



Although the insect for which I propose this name is extremely 

 near to Ccedius, it would be misleading to attribute it to that 

 genus on account of the characters specified above. The absence 

 of a scutellum forbids its association with Cwdiomorpha or 

 Iso2')teron, while from Sohas (which has no scutellum) it difiers by 

 its emarginate clypeus, posterior tibipe strongly spinose and apical 

 joint of maxillary palpi decidedly (though not strongly) securi- 

 form. 



P. squamosus, sp. nov. Latus ; minus convexus ; piceus, squamis- 



brevibus pallidis suberectis (his in prothorace confuse, in 



elytris seriatim, positis) vestitus ; indumento terreo tectus 



(hoc raso, superficie subtilius sat crebre punctulata granulis- 



sat crebris inter puncturas intermixtis) ; prothorace quam 



longiori plus duplo latiori, postice quam antice du]3lo latiori, 



mox intra margines distincte minus anguste deplanato, 



lateribus sat rotundatis, angulis anticis obtusis posticis sub- 



rotundatis vix distinctis, basi baud bisinuata ; elytris obscure 



striatis, interstitiis subconvexis ; tibiis anticis externe den- 



tatis, posterioribus 4 fortiter spinosis. Long., 2^1. ; lat., If 1. 



The anterior tibiae on the internal margin are strongly bent at 



the base, thence nearly straight to the apex, where is a short 



stout spine ; on the external margin they widen from the base 



very rapidly into a strong obtuse tooth a little above the middle, 



immediately below which the tibia is scarcely wider than at the 



base ; thence the tibia widens externally in an arcuate manner to 



the apex, so that the apex itself is externally in the form of a 



very strong obtuse tooth. The front tarsi (which are very 



much shorter than the other four) lie back in repose in a furrow 



on the face of the tibia. Although the base of the prothorax is 



not bisinuate, there is a slight unevenness in its outline (which.
