{in lift., 25.X.21) that on seeing Deville's papei- he had examined the tarsi of 

 his supposed N. hrevicollis (which came from various localities in England, 

 Scotland, Ireland, France, Italy, and Austria) and found most of them to be 

 pilose. In September 1921 he vras in the Lake District at Borrowdale and 

 "'took a few specimens of Nehria of wbich only one had the bind tarsi pilose, 

 in the others the upper surface was quite glabrous { — N. iberica Oliveira)." 

 He kindly asked me to look over all his specimens, and he appears to have 

 iV. hrevicollis F. from Borrowdale, Arran, Dublin, Cromer, Reading, Christ- 

 church, Weymouth, Rouen, Provence, Jura, Bregenz, and Nancy; and 

 N. iberica Oliv. from Borrowdale, Connemara, Morthoe, and Valembrosa. 

 I find that the series in my cabinet all come from Richmond Park and all are 

 N. brevicollis. Lt.-Col. Ste. Claire Deville tells me Mr. Champion has sent him 

 N. hrevicollis from Surrey and Scotland. He further states that he is con- 

 vinced that the two insects are truly distinct. He and Dr. Jeannel have 

 verified the observations of Pasteur Huberthal on the male genitalia (the penis 

 of iherica is much more slender, less constricted at the base and less strongly 

 curved inwards than in hrevicollis) and have found them to be absolutely true.

Notes on various Coleoptera, — Late in January, 1921, when collecting near 

 Sherborne, Dorset, I had the good fortune to come across an old uprooted tree 

 to which plenty of earth wns attached. Here the following species put in 

 an appearance : Dacne humeralis F., Rhizophat/us iHtraUelocollis Gyll., and 

 Trichonyx sulcicollis Reich. The first two species occurred only twice under 

 bark on the outer extremities of the roots, but the Trichonyx, of which four or 

 five examples were taken, were found where the earth formed a thick layer 

 o>er the partlj^ decayed roots. As far as could be judged fiom a rather rapid 

 examination, they were preying on some very small wingless insects that 

 occurred rather abundantly in this portion of the roots. These and the 

 'I'richo7iyx ^^ ere taken home alive and kept for over a week in the hope of 

 settling this point. However, though the former unquestionably disappeared, 

 the Trichonyx yvtixe not observed devouring them. As far as my present know- 

 ledge goes, the three species mentioned above have not been recorded for 

 Dorset before. 



Two years ago I received three specimens of a Haeinonia (which I have not 

 been able to determine satisfactorily) from Mr. A. Hutchinson, of Pembroke 

 College, Cambridge. He took them in the water-net at Talkin Tarn, Cumber- 

 land, on 9.ix.l920, Avhilst working the bottom of the Tarn for Derouectes 

 ilepressvsY. Since this, Dr. J 03', Dr. A. \V. Nicholson, and Mr. Blair have 

 all very kindly examined the specimens, and have given their opinions on them. 

 Provisionally, I am inclined to regard them as intermediates between Haeinonia 

 curtisi Lac. and H. curtisi Lac. var. appendiculata Pz. I have not examined 

 the aedeagus, as I have not got specimens of the European species with which ■ 

 to compare ihem, but 1 hope shortly to be able to do so. It is well known 

 that the species of Huenionia, at any rate as constituted at present, rest on very 

 unsatisfactory characters, and that they require critical examination and 

 comparison inter se before they can be regarded as distinct species. —
