260 Rev. H. Clark’s Notes on the 
§ A. Species elytris apice rotundatis. 
a. Elytris costatis. [Sp. 1—10.] 
b. Elytris planis. [Sp. 11—14.] 
§ B. Species elytris apice emarginatis. [Sp. 15, 16.] 
In order that I might be supplied with as much material as 
possible in my examination of the genus, my friend Mr. Baly has 
liberally placed in my hands the whole of the species in his 
collection. I have not, however, accepted his kind suggestion that 
I should describe the uniques which that collection contains ; it is 
better that these should be left to be described by himself at some 
future day, for this simple reason, which I deem to be not only 
important but of general application :—such is the multiplication of 
species that are becoming known to us, and such therefore the 
difficulty of accurately describing them, that typical specimens, on 
which descriptions are based, become of greater importance than 
ever; and hence I venture to believe that every worker will 
specially desire to have always within his reach the materials on 
which his own work has been based ; in the case of monographs 
this difficulty must of course be accepted as unavoidable; it seems, 
however, to my mind that it is better to avoid it when possible. 
It will be seen that I have omitted to notice certain manuscript 
names in Dejean’s Catalogue: I have done so with regret, but 
I can ascertain nothing with certainty respecting them.

Oblongo-ovalis, ad apicem rotundata, depressa, costata, sub- 
tiliter et crebre variolata, flava, nigro-notata: caput variolatum, 
nigrum; thorax transversus (ad apicem modice excavatus, 
lateribus antice rotundatis et basi transversa) depressus, et 
ad margines Jaté sed haud profunde exfossus; quoad colorem 
latera Jate flava sunt, discus medius nigrescit; scutellum tri- 
angulare, nigrum; elytra modice post medium ampliora 
costas quinque continent, una suturalis et communis, altera 
marginalis, tres quoque intervallo zequali mediz haud apicem 
attinent; costee exstantes, sed praecipue sublateralis pro- 
minens versus humeros exstat; quoad colorem elytra flava

vitta abbreviata inter suturam et costam 24™ longitudine
