The observations of the Rev. G. T. Rudd, upon the distinctions of species in this 

 intricate genus, satisfactorily prove that the depression in the region of the 

 scuteUum is a character of very little importance, he having met with several 

 species (amongst them, Ag. parumpunctatum) in the same places, and under 

 the same circumstances, with that part more or less depressed, and remarkably 

 so in one specimen of the insect just named : — he also justly observes, that 

 the difference in form and colour is not sufficient in several of the species to 

 warrant a distinction, as at the root of the same tree he collects perhaps a dozen 

 specimens, no two of which agree in every particular. 



TIae above remarks, as well as those contained in my observations upon this 

 genus and upon Amara, fully show the necessity of a practical acquaintance 

 with every species previously to deciding upon their distinctions ; and I cannot 

 here avoid noticing, as bearing upon the subject, the extreme difficulty which 

 the student of entomology necessarily experiences in this country from the 

 lamentable state of our public collections, of which even the most extensive is 

 for the most part unnamed and unarranged, and may be characterized as 

 '' rudis et indigestaque moles;" and a mere collection, in the above state, 

 however extensive, is, for the purposes of science, as useless as the hoards of 

 the miser are to his fellow-creatures : it is therefore probable that, in such 

 collections, some few indigenous species may remain undetected by me, owing 

 to the impossibility of ascertaining them by the mere inspection of unnamed 

 specimens, without convenient accommodations for making comparisons, either 

 with other specimens or books.
