By the last mail I received from Mr. H. W. Bates, the well-known South 



American traveller and vice-president of the Entomological Society of London, 



a letter containing some valuable information respecting a few Coleoptera 



which I forwarded to him from this Province in October last. I give the 



greater part of it verbatim, and exhibit specimens of the new species referred 



to, which I shall afterwards place in the Museum. Mr. Bates writes as 



follows : — 



" I distributed the Coleoptera which you kindly sent me in the little box, 



amongst a number of entomologists especially devoted to the various groups, 



telling them to keep the specimens in exchange for the names. After much 



delay I have got replies from all of them, but there still remain a few species 



of which no one knows anything. The resvilt is on the adjoining page. They 



are- all (myself included) willing to describe the new species, but all say it is 



very requisite to have several specimens and both sexes to do this satisfactorily. 



You will get finer things and more species from the hilly districts. You will 



observe the large amount of new species, and even of new genera ; this shows 



what a fine new field you have. I saw Mr. Scott, and he told me he was 



willing to undertake your Hemiptera. Mr. Yerrall, secretary to the 



Entomological Society, is willing to describe your Diptera."

2. Demetrida picea (Chaudoir). There are several pretty spotted species 



of this genus in New Zealand, very rare in collections here. 



3. Dicrochile, n. sp. There appear to be several closely allied species of 



this pretty genus, which is distinguished by its bilobed labrum 

 (upper lip), 



4. Pterostichus. More specimens wanted. 



5. New genus near Gymbeba (Pascoe). Family Heteromera.
