332 Mr. M. Cameron on new Staphylinidas 



tinguished by the ground-sculpture of the head and thorax, 

 the thickened last joint of the antennas, and the obsolete 

 puncturation of the fore parts. 



Head transverse, with the eyes broader than the thorax, 

 sparingly and obsoletely punctured. Antennas testaceous, 

 of similar structure to the preceding, except for the eleventh 

 joint, which is stouter and longer than the tenth. Thorax 

 formed as in P. insularis, puncturation scanty and very 

 obsolete. Elytra as in the preceding species and without 

 visible ground-sculpture. Abdomeu reddish with the usual 

 imbricated sculpture and coarse pubescence. 



<$ . Last ventral plate gradually narrowed and produced. 



Jamaica, Haiti. Type in my collection. 



PlDEEINI. 



15. Stilicopsis circumflexus, sp. n. 

 (Fauvel, in Utt.) 



Pitchy red, scarcely shining ; antennas, legs, apex of 

 abdomen, and elytra testaceous, the latter with well-marked 

 black lateral spot. Seventh abdominal segment furnished 

 posteriorly with a narrow white membranous border. 



Length 2*8 to 3 mm. 



Variety. — Entirely reddish testaceous with elytral spot ill- 

 defined. Type-form readily recognized by the coloration, 

 but the variety very similar to S. brevis, Shp., in general 

 appearance, but differs by the rather narrower head, distinctly 

 narrower thorax, and shorter elytra. Head large, sub- 

 orbicular, as broad as the elytra. Eyes rather large, pro- 

 minent ; temples not quite so long as the diameter of the 

 eyes, slightly convergent to the posterior angles, which are 

 rounded ; puncturation close and umbilicate. Labrum pro- 

 duced in a median lobe in front, notched in the middle of 

 the anterior margin, external to the lobe on either side with 

 a short triangular tooth directed forwards and inwards. 

 Antennas as long as the head and thorax j first joint elongate, 

 rather stout, three times as long as the second ; second 

 narrower than the first, a little longer than broad, shorter 

 than third ; third to ninth longer than broad, gradually 

 decreasing in length ; tenth about as long as broad ; eleventh 

 not so long as the two preceding together. Thorax a little 

 transverse, narrower than the head and elytra, widest at the 

 anterior angles which are obtusely rounded, narrowed to the 

 posterior angles which are effaced ; sides with two or three 

 setae; puncturation close and umbilicate. Elytra scarcely
