some New Species of Oxypoda. 191 
O. rrparta, Fair. 1859 (nec Th. 1855). This name 
must be changed as above indicated, and I propose for it 
the name of O. mutata, and subjoin a diagnosis of it. 
O. Murata. Elongata, rufo ferruginea, abdomine medio 
nigricante, antennis pedibusque testaceis, dense fortiter, 
subrugulose-punctata, abdomine apicem versus paulo 
angustato. Long. 1} ln. 
This species is distinguished from all our other British 
species by its stronger and dense punctuation. Fair- 
maire describes the head as black, but I do not find it so 
in our British examples. 
O. BrAcHypTERA, Steph. Elongata, subparallela, haud 
nitida, rufo-ferruginea, abdomine medio late nigricante, 
dense, subtiliter punctata, elytris thorace paulo breviori- 
bus, fereque angustioribus. Long. | lin. 
Aleochara brachyptera, Steph. Ill. Brit, Ent. V. p. 128. 
Oxypoda forticornis, Fair. Ann. Fr. 1859, p. 37 (forte). 
Of an elongate, narrow, and rather parallel form, but 
with the extremity of the abdomen distinctly narrowed. 
The antennz and legs are yellowish; the head, thorax, 
and elytra of an obscure reddish colour; the hind-body 
reddish at the base, and at the extremity, black in the 
middle. The antenne are rather long and stout for the 
size of the insect, a little thickened towards the apex, the 
basal joints being stout; the second jomt much longer 
than the third, the third triangular, being much narrowed 
at the base, fourth joint shghtly transverse, 5-10 strongly 
so, eleventh joint long and stout, quite as long as the two 
preceding together. Head rather broad, much narrower 
than the thorax. Thorax nearly twice as broad as it is 
long, not much rounded at the sides, but a little rounded 
and narrowed towards the anterior angles, thickly and 
finely punctured with a short pubescence; the elytra are 
rather shorter than the thorax, and even a little narrower 
than it, closely and finely punctured, but rather more 
coarsely than the thorax; hind-body densely and finely 
punctured with a close, not altogether fine pubescence ; 
the sete of the extremity small and indistinct. 
This little species is clearly the Aleochara brachyptera 
of Stephens’ description above referred to. It must be very
