refers it to M. Lacordaire’s Groupe Hylaspites. Had I been able 
to examine a type previously, or had this character been recorded 
by the author of the genus or by M. Lacordaire, I should not 
have referred to Menippus the species which I have so referred, 
and I now regret to find that they cannot stand as congeneric 
with JL. cynicus. They are three in number. The first of them 
(M. macuiicollis) is I now believe a var. of Dircema ( Galeruca) 
australis, Bohem, while the other two (J. elegans and 4-notatus ) 
may be referred to Adimonia, although MW. elegans is by no 
means a typical Adimonza (approaching Buphonida in its head 
being scarcely narrower than its prothorax but differing from 
Buphonida even more than from Adimonia in its claws being 
scarcely bifid, almost simple). 
MONOLEPTA. 
There is no genus of the Galerucides more difficult to charac- 
terise definitely than this. Mr. Baly (Journ. Linn. Soc. XX.) 
states that it varies in respect of the closure of the front coxe 
and in the length of the elytral epipleure, while Dr. Chapuis 
says that some of its species (having their front coxz open) ought 
not to remain init and Mr. Jacoby tells us that those with 
elongate elytral epipleure (in spite of Mr. Baly’s statement that 
the type of the genus is one of these) ought to be removed. 
Among the numerous species (attributed to the genus) before me 
T find considerable variation in the elytral epipleure, but I have 
not seen any in which I can find that the front coxz are open. 
These discrepancies of diagnosis occasion me considerable diffi- 
culty in respect of several new species before me, especially in 
view of the fact (referred to above) that Dr. Chapuis and Mr. 
Baly do not seem to mean quite the same by “open” or “closed ” 
front coxre. It seems best, under the circumstances to define 
the characters which in this memoir I regard as those of 
Monolepta, viz., front cox closed in the sense that the apex of 
the prosternal epimera is not (as it is in e.g., Luperus) a free pro- 
jection laid against the surface of the coxa, elytral epipleure 
failing (or at least only very obscurely traceable) behind the 
middle of the elytra, tibiz mucronate ; basal joint of hind tarsi 
at least as long as the following joints together, claws append- 
iculate. 
It is extremely difficult, in my experience, to draw a sharp line 
of distinction between the Groupes Monoleptites and Luperites. 
In some of the species that I have attributed to Monolepta 
(ML. modesta, quesita, and Benalle particularly) the closure of 
the front cox is excessively fine and it is possible that they are 
examples of what Dr. Baly considers species with the cox not 
quite closed but nevertheless attributable to Monolepta.- Alt
