192 Mr. G. J. Arrow on Cohoptera 



In reviewing the genus Platychora, Murray (/. c. p. 175) 

 mentioned a species "P. depJanata, Boh., from Natal." In 

 the Munich Catalogue this is tigured, by a curious mistake, as 

 riatychora deplanatay Murr., Old Calabar. So far as I know, 

 it has never been characterised. It is quite differently 

 sculptured to the other species, the punctures being less evenly 

 distributed. The prothorax and elytra are shining along 

 their median part and moderately finely punctured, but the 

 puncturation becomes much coarser towards the sides, where 

 there is a clothing of stiff grey hairs, which form rows at the 

 sides of the elytra. The head is finely and closely punctured 

 and the pygidium is rugosely punctured and setose. There 

 are broad margins to the prothorax and elytra. Length 

 7 mm. 



Temuochilidse. 



Two different insects have been united under the name o£ 

 Gyvinochila squamosa^ Gray. That described and figured by 

 Gray is an Australian Leperina, since described as L. decorata, 

 Erichs., and the type of Hope's genus Lepidopteryx, which 

 antedates by four years the name Leperina. Tlie species 

 described by Murray under the same name in the Ann. & 

 Mag. Nat. Hist. 1867, xix. p. 335, is the common African 

 Gymnochila varia, F. 



Lophocateres nanus, Olliff, is not distinguishable from the 

 widely-distributed L. pusillus, Klug. 



Cucujidae. 



Mr. Blackburn has been misled in declaring Ipsaphes 

 moerosus, Pascoe, a synonym of Platisus obscurus, Erichs. 

 As to the advisability of merging the two genera I am 

 inclined to agree with him, in spite of a considerable difference 

 in the form of the head ; but the two species are so different 

 that it is obvious Mr. Blackburn does not know Pascoe's 

 insect, which is not only entirely different in colour but 

 double the size and quite differently proportioned. I am 

 surprised, however, that Mr. Blackburn has rejected i/?sa^Aes 

 bicolor, Olliff (which he seems to have rightly identified), 

 from the genus. The tarsi of this (the types of both species 

 of Ipsaphes are in the British Museum) are quite different 

 from those of Cucujus, all but the last joint being very short 

 and of equal length. Olliff's species differs little from 

 Pascoe's, except in the differently coloured and relatively 

 shorter abdomen and elytra. 



Lamophlceus hrevi'ceps, Sharp, is L, reitleri, Grouv.
