THE ENTOMOLOGIST. 43 



divided into three or four by continental Lepidopterists : the 

 remarkable specimens bred by Mr. Hellins will tend to throw 

 light on this hitherto puzzling question, — E. Newman.'] 



Dasijcainpa ruhujinea in the Ide of Wight. — Eight spe- 

 cimens of Uasycampa rubiginea were taken at ivy-blossoms 

 near here from the 23rd to the *26th of October last, both 

 days inclusive. — Jameft Ingram ; February Q, 1866. 



Scarcity of Wasps in 1805. — It is very singular that wasps 

 should have been so plentiful at Brixton and Streatham as 

 Mr. H. W. Neate reports, for at Tooting, which is not three 

 miles from Streatham, they have been very scarce. In 1864 

 I destroyed thirteen nests, while in '65 I did not find one ; 

 but though wasps were so scarce, I never before noticed so 

 many hornets. With us the bees took to eating the over- 

 ripe fruit, as the wasps usually do. — Edwin Curzon ; Grove 

 House, Tooting, February 6, 1866. 



Anchouienus prasinus : has it explosive powers? — It is 

 well known that Clairville and other continental writers have 

 attributed explosive powers, like those of Brachinus crepi- 

 tans, to the above-named beetle ; but I have been unable to 

 obtain satisfactory proof of such a property having been ex- 

 hibited by British specimens. Can any reader of the ' En- 

 tomologist' oblige me with information on the subject.? —

Apion dijformis at Southsea. — I have discovered a habitat 

 of Apion difformis, and have captured several specimens. 

 Having taken a pair in cop., I find that it is the male only 

 that has the bifid tooth on the epigastrium : the feniale is 

 very much smaller, and very different in many respects. — 

 H. Moncreaff ; Southsea, December 14, 1865. 



Hydroporus neglectus of Schauni discovered in Britain.'-^ 

 I have during the last fortnight discovered and determined^ 

 a well-marked water-beetle, as yet undescribed as British. 



Hydroporus neglectus, Schaum, Ent. Zeit. Stett. 1845, 



p. 409. 

 It is a very distinct species, and is the smallest of our uni- 

 colorous Ilydropori, except H. Scalesianus. It is reddish 

 brown, with the thorax somewhat darker, and is most nearly 

 allied to II. trislis and H. umbrosus. From H. tristis it is 

 readily distinguished by its much smaller size, the more
