Mr. A. Murray ow Coleoptera from Old Calabar. 445 



yet, I have only received a broken specimen, wanting both head 

 and thorax, and am therefore unable to describe it. It has two 

 large yellow patches on each elytron, the basal nearly round, 

 and the apical transversely oblong, both with very slight traces 

 of jagged edges.

GoNiOTROPis, Gray. 



The species which follows certainly belongs to this genus, 

 although it differs in one or two unessential points from the 

 characters which have been given as generic by Gray. That 

 author gives the mandibles as pluridentate on the inner side, 

 and the anterior thighs as dentate on the under side, neither of 

 which is the case in my G. Wyliei ; but, as in all other respects 

 it agrees with the diagnosis of Goniotropis^j I do not propose to 

 make a new genus for it on account of them, but merely with- 

 draw the above specialties from the characters of the genus, and 

 thus widen it to receive the following species. 



1. G. Wyliei, mihL 



Castanea, nitida, Isevis; capite antice et postice levissime 

 punctato, vertice elevato, impunctato; mandibulis elongatis, 

 robustis, non dentatis; labro integro; thorace marginato, 

 angulis posticis fere rectis sine emarginatione ; elytris, capite 

 et thorace paulo longioribus, parallelis, cum carina marginali 

 interrupta et fortius plicata versus apicem; femoribus non 

 dentatis, tibiis anterioribus arcuatis, intus fortiter emarginatis. 



Long. 5 lin., lat. IJ lin. 



Colour uniform chestnut, shining, smooth ; head faintly, aci- 

 cularly, irregularly punctate in front, and still more sparingly 

 behind, with the vertex raised and impunctate; clypeus solid 

 and smooth, outline in front very slightly concave; labrum 

 transverse, and almost as broad in front as behind, entire f, 

 a row of punctures, from which hairs proceed, extending along 



* The reader will find the generic as well as the specific characters no- 

 ticed in the following description, so that he can satisfy himself that I have 

 not overlooked any of importance. 



t The labrum certainly cannot be called emarginate, although perhaps 

 the anterior angles may be said to be very slightly more advanced than the 

 centre of the anterior margin ; still the line of margin is very nearly straight* 

 A similar slight inequality would perhaps explain how the figure published 

 by Gray of his G. Brasiliensis shows an emarginate labrum, while he makes 

 no mention of its emargination in the text, and would confirm the view 

 taken by Lacordaire, that the genws Ictinus of Castelnau (which has the
