116 Mr. M. Cameron on neio Staphylinidce 



gradually increasing in breadth. Thorax scarcely as wide 

 as the head, with a dorsal row of ten or eleven rather small 

 punctures, which are somewhat confused anteriorly, a similar 

 row of eight or nine externally, and five or six close to the 

 anterior angles. Elytra a little broader than, but scarcely as 

 long as, the thorax, longer than broad, very sparingly, finely, 

 and obsoletely punctured *. Abdomen very finely and very 

 sparingly punctured. 



Grenada and Mustique {H. H. Smith). Type in British 

 Museum. 



49. Diochus perplexus, sp. n. 



(Fauvel, in litt.) 



Pitchy-brown, shining ; thorax with a dorsal row of three 

 small punctures on either side. Antennre with the first 

 three joints, and the legs, yellow testaceous. 



Length 2 5 mm. 



Very similar in build to D. nanus, Er., but the head a 

 little broader behind and the thorax less narrow, the punc- 

 tures of the head are also more numerous and more in 

 series than in that species. 



Head subquadrate, very slightly widened behind, with a 

 row of small, closely-placed punctures internal to the eye on 

 either side, and a few others posteriorly and on the temples. 

 Antennae as in D. nanus, Er. Thorax a little wider than 

 the head, cylindrical, with three punctures (the anterior 

 remote and more external) on either side, and four or five 

 near the lateral margin. Elytra a little broader than, but 

 scarcely as long as, the thorax, longer than broad, with three 

 rows of small and obsolete punctures along the disc. 

 Abdomen very finely and moderately closely punctured and 

 pubescent.

50. Diochus apicipennis, sp. n. 



(Fauvel, in litt.) 



Shining, chestnut-red; the apex of the elytra and the 

 abdomen more or less infuscate. Thorax with a dorsal series 

 of three punctures on either side. Elytra very sparingly, 

 scarcely perceptibly punctured. 



Length 3-4 mm. 



Build of D. nanus, Er., but with the head less sparingly 



• This puncturation is variable, and is much more distinct in sonjo 

 exaiuples.
