DESCRIPTION OF A NEW GENUS AND SPECIES OF STAPHYLINIDE 
(FROM SOUTH AUSTRALIA). 
BY D. SHARP, M.B. 
SARTALLUS: Gen. nov. Staphylinidarum (Ozxytelini). 
Corpus latum, robustum, haud depressum, alatum. Caput 
thorace minus et angustius, porrectum, basi via constrictum, oculis 
semi-globosis, modice prominulis. Labrum transcersum, medio emargi- 
natum, margine antico dense setigero. Mandibule prominentes, acumi- 
nate, irregulariter dentate. Mazille mala interiore margine exteriore 
coriaceo, interiore membranaceo, apicem versus spinulis octo, et pubes- 
centid nonnulld instructa ; mala exteriore longiore, coriaced, apice 
Jonge et dense pubescente. Palpi macillares mald exteriore parum 
longiores, articulo primo minuto, secundo elongato-obconico, tertio hoc 
nvix longiore, quarto minuto, subulato. Labium ligulé late emargi- 
natd, sub-bilobatd, paraglossis occultis. Palpi labiales articulis duobus 
primis sub-wqualibus, tertio minuto. Antenne fracte, breviuscule, 
articulo primo elongato, ultimis tribus praecedentibus distincte 
majoribus. LElytra truncata, apice ciliata. Abdomen latum, haud 
cylindricum, marginatum. Pedes tibiis anticis evidenter incrassatis, 
geniculis constrictis, externe fortius breviter spinulosis, intermediis et 
posticis spinuiis longioribus, inter spinulas setulosis. Tarsis omnibus 
quingue articulatis ; articulo primo obsoleto, a tibia obtecto, tribus 
sequentibus brevibus, ultimo elongato, praecedentibus conjunctis longiore. 
This remarkable insect, though much allied to Bledius, has an en- 
tirely different and very peculiar appearance ; its broad, robust, and quite 
uncylindric, but somewhat convex form giving it a facies peculiar to 
itself. Its tarsi might well be supposed 4-jointed ; but, when mounted 
in balsam, and examined with a good microscope, a fifth small basal 
joint, concealed by the tibia, is distinctly revealed. A specimen sent 
by me to M. Fauvel was returned by him as probably belonging to the 
Nitidulide ; an opinion which he must have formed, however, on a very 
slight examination. 
S. stenatus. Testaceus, oculis nigris, elytris medio plus minusve 
distincte piceo-signatis ; capite prothoraceque nitidis, fortiter haud 
crebre punctatis, elytris sub-opacis, apice ciliatis, vage punctatis. 
: Mas ; abdominis segmenti septimi ventralis lateribus utringue 
hamato- productis, acuminatis.
