162 STAPHYLINIDE. 
parvis; prothorace transverso elytris latiore et longiore; abdomine omnino densissime subtilissime 
punctato, opaco. 
Long. 44 millim. 
Hab. Guaremaua, Totonicapam, between 8500 and 10,500 feet (Champion). 
Antenne rather slender, the basal joint sordid red, third joint quite as long as the second, 
all the joints longer than broad, terminal joint slender and elongate, as long as the two 
preceding together, more dilute in colour, being obscurely flavescent towards the apex. 
Head small, subacuminate in front, with quite small eyes. Thorax large, strongly 
transverse, very convex transversely, rounded at the sides and a little narrowed in front, 
rather closely punctate. Elytra not so long as the thorax, closely and somewhat coarsely 
punctate. Hind body much more densely and finely punctate than are the anterior 
parts. 
This is a peculiar species with very short metasternum, so that the middle coxe very 
nearly attain the hind margin of the metasternum; the mesosternum is carinate along 
the middle: the structure of the front tarsi is very obscure; but I think they are five- 
jointed. Three individuals have been found. 
8. Oxypoda palpalis. (Tab. V. fig. 4.) 
Angustula, piceo-ferruginea, antennarum basi, palpis, pedibus abdominisque apice testaceis, crebre punctulata 
evidenterque pubescens ; antennis crassis, articulis 4°-10™ fortiter transversis. 
Long. 32 millim. 
Hab. GUATEMALA, near the city (Champion). 
Antenne stout, of Calodera-like form, ferruginous, paler at the base; third joint 
rather short, shorter than the second; fourth very short, strongly transverse, a little 
narrower than the following joints, which are all similar in breadth and nearly so in 
length; the terminal joint is elongate, longer than the two preceding together, obtuse 
at apex. Maxillary palpi elongate and slender. Head narrow, obsoletely punctate. 
Thorax convex, not quite so long as broad, rounded at the sides and base, and narrowed 
in front, obscurely punctate. Elytra about as long as the thorax, moderately closely 
and finely punctate. Hind body elongate and slender, pointed behind; the basal 
segments pitchy, ferruginous behind; the seventh and the greater part of the sixth 
yellow. Legs yellow; the hind tibie rather short, their tarsi elongate, fully as long as 
the tibice. 
Only one individual has been found. The insect is an aberrant one, and will no 
doubt have to be removed from Oxypoda, if it be only on account of the elongate third 
joint of the maxillary palpi, which is similar to that extant in Myllena. The tarsi are 
slender and bear a rather long pubescence ; and their articulations are very difficult to 
distinguish : Iam sure, however, those of the hind feet are five-jointed, but am not quite 
certain that there are more than four articles on the middle feet, though I believe I 
distinguish five. One of the front feet is broken off; and I am quite unable to form any
