Mr. A. Murray on Coleoptera from Old Calabar, 129 



This species is very close to the Homalolachnus vertagoides of 

 Laferte, but differs from his description in the following parti- 

 culars : viz. In my species the head is punctate behind, and 

 there are traces of punctuation near the eyes, while in vertagoides 

 the head is said to be smooth {lisse). In it, too, the thorax is 

 said to have its greatest breadth at about two-fifths of its length, 

 and the posterior angles are said to form a right angle very slightly 

 obtuse, whilst in my species the greatest breadth is at the middle, 

 and the posterior angles are rounded and something more than 

 " very slightly obtuse/^ The spots on the elytra do not cover 

 the same interstices, Laferte saying that in his species the an- 

 terior spot is separated from the suture by only two interstitial 

 spaces (including in them the sutural space), while in my species 

 it is separated therefrom by three spaces. The colour of the 

 legs also does not quite correspond ; the knees are all black in 

 mine, and the middle of the tibise of the two anterior pair tes- 

 taceous, while in vertagoides Laferte gives the whole of the thighs 

 as testaceous, and the whole of the tibise as blackish.

Rare. Till corrected by M. de Laferte, I was under the im- 

 pression that this species was different from the Ch. oculatus, 

 Fab., and had attached the name Ch. Chevrolatii to it, in honour 

 of my friend M. Chevrolat, in the figure which I published of 

 it in Plate XIII. in the ^ Annals' of June last, 1857. The reader 

 is requested to make the following alterations in the names at 

 the bottom of that plate : viz. in place of Chlcenius Chevrolatii to 

 insert 0. oculatus. Fab. ; and for Chl(2nius diaphanicollis to sub- 

 stitute Eccoptomenus eximiuSj Dej.
