122 Mr. A. Murray on Coleoptera from Old Calabar, 



the base on each side. Scutellum triangular, with the sides 

 slightly sinuate, smooth and impunctate. Elytra sparingly 

 pilose, short, convex, and looking somewhat as if curtailed, 

 punctate-striate, the striae deep, particularly towards the apex, 

 and with the interstices convex and punctate; marginal space 

 with a distinct row of transverse punctures ; two clear red or 

 ferruginous spots on each elytron, the anterior reaching to the 

 margin, and extending over the 6th, 6th, 7th, 8th and 9th in- 

 terstitial spaces ; this spot runs obliquely from the shoulder in 

 the direction of the suture, is rounded opposite to it, and then 

 returns in a slightly rounded line to the margin ; the posterior 

 spot is short and nearly transverse, and is confined to four in- 

 terstitial spaces, the 5th, 6th, 7th and 8th, and is most prolonged 

 on the 7th ; the spots are of the same texture as the rest of the 

 elytra, and are not raised above their surface ; apex emarginate. 

 Under-side with the prosternum and breast deeply punctured, 

 the prosternum more sparsely than the breast ; inferior margin 

 of thorax shining, and with faint traces of punctures ; inflexed 

 margin of elytra finely punctate ; sides of segments of abdomen 

 coarsely punctate, less so towards the apex, middle portion 

 finely aciculated. Legs pitchy-black, with tibiae piceous and 

 tarsi dark ferruginous. 



I have named this species in honour of the Marquis de 

 Laferte Senectere, who has published an able revision of the 

 group on which we are at present occupied, and has been kind 

 enough to give me the benefit of his information as to my new 

 species.

I believe this species to be, as above stated, the grossus of 

 Hope. His description, as is usual with him, is more concise 

 than we could have wished ; and I shall therefore add a some- 

 what more detailed description, although the admirable figure 

 by M. Migneaux, which the reader will find in my last plate of 

 Old Calabar species, renders any additional description scarcely 

 necessary.
