Mr. A. Murray on Coleoptera from Old Calabar. ^i? 



Morionidse. 



MoRio, Latr. 



1. M. Guineensis, Imlioff, Verb. d. nat. Gesells. in Basely vi. 166. 

 M. Senegalensis, Dej. Cat. 



Niger, nitidus, depressus ; protliorace lato, subcordato, angulis 

 anticis prorainulis, posticis rcctis, medio et utrinque intra 

 basin sat profiinde canaliculato ; elytris prothoracis fere lati- 

 tudinis quam latis non duplo longioribus, parallelis, evidenter 

 striatis, interstitiis subconvexis Isevibus; pedibus ferrugineo- 

 fuscis. 



Long. 81-6 lin., lat. 3-2 lin. 



This species varies considerably in size, so much so as almost 

 to lead one to suppose that there are at least two species con- 

 founded in it, particulai'ly as the larger individuals seem to the 

 eye broader in proportion than the smaller ones. Careful ex- 

 amination and measurement, however, show that this is a mere 

 ocular deception, the relative proportions being the same. It ap- 

 proaches very nearly to antkracinus, Bohem., andpai'allelus, Klug. 

 The relative proportions of this species are as follow : — Thorax 

 broader than long. Length of elytra rather more than twice 

 the length of thorax, and about l^ or If times the breadth of 

 the elytra. In my specimens from Senegal the elytra are rather 

 more elongate, being nearly twice as long as they are broad ; 

 but as I can find no other difference, I have not considered it a 

 new species. 



Platynodes, Westw.

 pi. 21. fig. A. PI. Xm. fig. 7. 



Niger, subnitidus ; capite magis nitido, antennarum articulis api- 

 calibus brunneis, superficie corporis lajvi ; singulo elytrorum 

 striis 7 simplicibus et gracillimis instructo, sj^atio inter striam 

 6 et 7 ad latera in carinam elevato, spatioque intra marginem 

 lateralera punctis parvis rotundatis impresso.

The insect I have from Old Calabar seems to be the same 

 species that has been already described and figured by Mr. West- 

 wood {loc. ciL). I have only received a single specimen, and I 

 find one or two trifling discrepancies between it and the figure 

 given by Mr. Westwood, as well as a typical specimen of Wester-
