116 Mr. M. Cameron on new Staphylinide 
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. Elytraa 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. 0. Ke 
(Fauvel, in litt.) 
Pitchy-brown, shining ; thorax with a dorsal row of three 
small punctures on either side. Antennz 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. 
Antenne as in JD. 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. LElytra 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, zn litt.) 
Shining, chestnut-red; the apex of the elytra and the 
abdomen more or less infuseate. 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 spnvinely 
* This puncturation is variable, and is much more distinct in some 
examples.
