wedge-form, or at least an approach. It departs from other spe- 

 cies of the genus in having the lateral processes of the rostrum, 

 forming the lower boundary of the groove for the antennae, rather 

 less prominent, the eyes more convex, and the antennse shorter. 

 It is not without considerable hesitation that I place this insect 

 in the genus Otiorhynchus. 



From Charles' Island. Found in sweeping the herbage in the 

 high central parts of the island.

From James' Island. 



The thorax is narrower than usual in this species, being less 

 dilated in the middle ; its sides are nearly parallel, but in front 

 it is rather suddenly constricted, and immediately behind the 

 constricted portion the thorax is sometimes a trifle broader than 

 elsewhere : the punctures in the thorax are very large and coarse, 

 and close together, the interspaces being mere ridges. The elytra 

 are nearly ovate, but the sides in the middle evince an approach 

 to paraUelism ; they are strongly punctured, and the punctures 

 are arranged in rows, and for the most part distinctly separated 

 from each other ; the interspaces between the rows of punctures 

 are impunctate, but present very narrow tubercles, and these are 

 rather widely separated on the fore-part of each elytron, but on 

 the apical portion they are longer and nearer together, and here 

 the interstices are somewhat convex; on the third, fifth and 

 seventh interspace the tubercles are rather more developed than 

 on the intermediate interspaces ; these tubercles are provided with 

 largeish semi-erect setiform scales, and these are of a brownish 

 yellow colour ; similar scales are scattered in other parts, and 

 sometimes the whole surface of the thorax and elytra is covered 

 with a brownish substance, of the nature of which I cannot 

 satisfy myself.
