STAPHYLINIDZ. 795 
race medio biseriatim, ad latera crebre, punctato, punctis seriatis irregularibus; elytris crebre, fortiter, 
seriatim punctatis. 
Long. 10 millim. 
Hab. Mxxico, Durango city, Villa Lerdo (Hoge). . 
In this insect the thoracic punctuation is coarser than is usually the case in the 
species with biseriate sculpture, and the series are irregular; but I think there is no 
doubt it really belongs to the group in question, though these characters, in addition 
to the large stature, give it a great resemblance to the species without serial thoracic 
punctuation. Head with coarse punctuation nowhere numerous, and on the middle 
extremely distant; hind angles much rounded. Thorax longer than broad, narrowed 
towards the base. Elytra each with five series of rather coarse punctures, and with 
irregular punctuation at the sides and apex. 
The two examples received are both females, and are in a bad state of preservation. 
SCOPEUS (p. 540). 
Casey (in Bull. Calif. Ac. Sci. ii. p. 220) has proposed two new genera, Scopewodera 
and Leptorus, dismembered from Scopeus, and to include certain of our species indi- 
cated by him (/.¢.). I content myself at present with pointing this out, for it would 
not be prudent to dismount the typical examples, frequently unique, of these fragile and 
minute insects to examine their structural characters. 
1(a). Scopzeus femoralis. 
Testaceus, parum convexus, subopacus, subtilissime punctatus; prothorace basi in medio subelevato, utrinque 
vix impresso. ; 
Long. 4 millim. 
Mas femoribus posterioribus incrassatis, margine posteriore concavo. 
Hab. MeExico, near the city (Hége). 
Antenne with the second and third joints subequal, the tenth joint about as long as 
broad. Head elongate, extremely finely and densely punctured, quite dull. Thorax 
oblong, rounded at the front and hind angles, yellow, rather shining, finely and not very 
densely punctate. Elytra longer than the thorax, finely not very densely punctate, a little 
shining. Male with a broad emargination of the last ventral plate; the basal segment 
depressed, deplanate and shining in the middle; the following two segments each with 
a fine seta on either side of the middle near the hind margin, the first of these segments 
with a small tubercle at the extreme base; hind femora rather incrassate, curvate, at 
their point of junction with the trochanters furnished on their upper face with a short 
pencil of black sete ; the upper edge of the hind margin of the femur minutely serrate 
at the extremity; and the tibize extremely minutely serrate and pubescent along the 
inner margin. 
_ This is not at all allied to any other of our species, and the remarkable characters 
of the male are quite unique. We have received only one example.
