MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 411 
elongate, strongly ciliated on the inner side. Maxillary palpi with the first article small, 
the second bent to the side and conical, the third cylindrical, about the length of the 
second, the fourth elongate, as long as all the rest together. Mentum slightly bisinuate 
in front. Labial palpi with the first article very short, the second and third equally 
long, the third elongate-oval. Ligula corneous, each anterior angle produced into a very 
slender, long coriaceous point, ciliated on the inner side. "Thorax as broad as the elytra 
at its base, which is bisinuated, with its angles slightly produced behind. Elytra trun- 
cate, leaving the last two segments exposed.  Prosternum articulated behind with the 
metasternum.  Metathorax without axillary pieces. Abdomen short, the first and fifth 
segments a little larger than the rest; fimbriz absent; the pygidium and part of the 
penultimate segment alone exposed. Legs moderate; thighs robust ; tibize rather widened 
at the apex, their terminal spurs very small. The first three articles of the tarsi dilated, 
hairy beneath. Claws stout, simple. 
The males are distinguished from the females by their head and their antenn: being 
longer and by the clypeus or epistome being impressed. 
This genus is composed of small insects which have considerable resemblance to some 
of the Brachypteride and also to some of the species of Epurea. It has also relations 
with Pria through its elongated antennz in the males and the prosternum resting on 
the metasternum. 
As already mentioned (at the commencement of the Carpophilide), I have had great 
doubt where to place this genus. It has much affinity with the Brachypteride, of which 
the species M. adustus is perhaps the strongest example. It is not less closely allied to 
Epurea, as is well shown in M. debilis and M. flavicans. When I was at the commence- 
ment of the Carpophili, it puzzled me with its contradictory affinities; and difficulties 
near at hand always appearing larger than those far off, I wished it away from Colastus, 
and resolved to place it between Carpophilus and Epurea. Now that I have come to 
that place, I wish it away back again near the Brachypteride. I believe, were I to do 
it over again, I should now make a separate group (Mystropide) for its reception, between 
the Brachypteride and the Carpophilide.
