334 Mr. M. Cameron on new Staphylinidre 



sculptured, impressed on either side behind the Avidest part; 

 disc with a fine median raised line. Elytra as long as the 

 thorax, as broad as the head and a little longer than broad, 

 a little rounded at the sides, pretty closely and moderately 

 finely punctured ; pubescence scanty. Abdomen with rather 

 close aciculate puncturation and moderately pubescent, 



c ? . First joint of posterior tarsi long and thick ; sixth 

 ventral plate rather broadly and moderately deeply emargi- 

 nate ; fifth ventral plate with a shallow emargination. 



Jamaica (Hope River district). Type in my collection. 



18. Stamnoderus dissimilis, sp. n. 



Entirely reddish testaceous ; elytra depressed on the disc, 

 widened behind. Front of head and thorax rather coarsely 

 and rugulosely sculptured. 



Length 5 mm. 



Somewhat resembling S. gracilis, Slip., in facies, the elytra 

 being narrow at the shoulders, widened behind, and depressed 

 on the disc. The colour is, however, more reddish ; the head 

 broader and much more finely, closely, and distinctly 

 sculptured; the thorax broader and more finely sculptured ; 

 the elytra more finely punctured, and the abdomen more 

 •closely and finely punctured. From S. labeo, Er., it differs by 

 its rather larger and more robust build, much more coarsely 

 sculptured head, broader and more distinctly sculptured 

 thorax with much less distinct lateral impressions, and the 

 more coarsely punctured elytra. From £. bernhaueri it 

 differs by the broader thorax with well-marked basal im- 

 pression and a smooth shining space on either side between 

 this and the lateral impression, by the shape of the elytra, 

 the much finer and scarcely aciculate puncturation of the 

 abdomen, and the much longer second joint of the antennae. 



Head large, convex behind, produced and depressed in 

 front of the eyes., which are large and prominent, posterior 

 .angles rounded ; closely and rugosely sculptured in front of 

 the level of the eyes, scarcely perceptibly punctured behind ; 

 foveolate on either side between the eyes. Antennae yellow, 

 long, slender; first joint elongate, second much shorter than 

 first, third much longer than second; fourth toseventh of about 

 equal length, much longer than broad ; eighth to tenth longer 

 than broad, gradually decreasing in length ; eleventh oblongs 

 ovate, longer than tenth. Thorax a little narrower than the 

 head, flask-shaped, rounded and dilated in the middle, 

 strongly narrowed in front, less strongly narrow^ d behind, 

 distinctly impressed at the base before the scutellum and on
