 Of PerlidcB, Nemoura variegala, Oliv., was the only common species, and the only 

 other that was noticed at all was Isopteryx tripunctata. Scop. 



Perhaps, on the whole, the time chosen for iny excursion was 

 ratlier late. The results, however, cannot be regarded as unsatisfactory.

PLhizophagus punctulatus, Guillebeau : synonymical note. — In the Bulletin de 

 la Societ6 Entomologique de France, 1897, p- 226, in a posthumous paper by F. 

 Guillebeau, a new Rhizophagtis is described under the name of R. punctulatus, upon 

 three specimens from Nantua, Eastern France. This insect, from the description, 

 is evidently conspecific with R. oblong icollis, Blatch and Horner [Ent. Mo. Mag., 

 xxviii, p. 303 (1892)], from Sherwood Forest and Bagots Park. R. punctulatus is 

 stated by Guillebeau to differ from R.ferrugineus and R. parallelocoUis by the fine 

 punctuation of the thorax and the shortness of the second joint of the antennje, and 

 from R. nitidulus by its ferruginous colour and the absence of the fovea upon the 

 last ventral segment. I possess an example of R. oblongicollis, obtained from the 

 Eev. T. Blackburn's British collection, without locality attached. — G. C. Champion,

Bagous nodulostis, OylL, at Pevensey. — On May 3rd, when collecting near 

 Pevensey with Mr. Donisthorpe, we were fortunate enough to meet with two or 

 three specimens of Bagous nodulosus. It was apparently difficult to get, as several 

 subsequent visits only produced a few examples, but a little later in the year I was 

 fortunate enough to obtain a nice series. They are extremely sluggish, and, not- 

 withstanding their large size, are more difficult to detect than any of the other 

 species of the genus, as far as my experience goes ; I found the best way to get them 

 was with the water net. After dragging the aquatic vegetation very violently and 

 repeatedly I took the whole of the mass in the net home, and found that repeated 

 examinations were necessary before all the specimens were detected. To give some 

 idea of how long they will remain without moving, I might mention that one speci- 

 men, when placed on a sheet of white paper, was fully ten minutes before it gave a 

 sign of life. Other species that occurred in the same ditch were — -6 a</o«5 alismatis 

 and B. glabrirostris (common), Thryogenes svirrhosus (in numbers), Hypera Pollux, 

 Cnemidotus impressus, Agabus Sturmi, Copelatus agilis, Hydroporus angustaius, 

 Hydrobius oblongus, and Hydrophilus piceus. — W. E. Bknnett, 15, Wellington

A note on three British Histeridce. — There are three genera in the Histeridce, 

 i-ecognised by those who more particularly study the Family, which are not yet 

 generally acknowledged by entomologists in England. Saprinus maritimus, Steph., 

 is a typical Pachylopus (Erichson, 1834), a genus belonging to both the Old and 

 New Worlds, but unlike Saprinus in being restricted in its number of species. 

 About ten or twelve only are known, against about 400 of ISaprinus. Kissister
