240 THE ENTOMOLOGIST. 
Kiniine Lreprmpoprrra.—Having often thought that there is 
room for improvement in the killing of Lepidoptera, I this season 
made use of, as I think, a new method, which I have found 
effective for the above purpose. Having procured a bottle with a 
wooden cap, which answers better than an ordinary cork, I then 
cut up small pieces of india-rubber and soaked them in chloro- 
form, which I found was largely absorbed by it. These pieces, 
after having been left in solution a day, were taken out and 
transferred to a dry corked bottle, and when exposed to the air 
they give off vapour and gradually shrink to their original size.—

HyYPERACMUS CRASSICORNIS, Grav.—Last year I recorded the 
occurrence of the female of this insect, but neither Holmgren 
or Gravenhorst appear to have been acquainted with the male 
of it. On the 3rd of this month, while sweeping some rough 
grass under trees, I had the good fortune to capture a fine pair, 
male and female, and can now describe the sexual distinctions. 
The male taken is somewhat larger than the female, and in colour 
and general appearance is like it, but the antenne differ in a very 
remarkable manner. In length they are as long as the whole 
insect, and are as thick as in the female, but the joints of the 
flagellum, instead of being transverse as in the latter, are all 
longer than broad. The first four are subequal and about three 
times as long as broad; the fifth is one-third shorter than the 
fourth, and they then gradually decrease in size until the penulti- 
mate, which is about one-third shorter than the apical. At the 
apex of the fourth and the base of the fifth is a small smooth 
excavation, the two together forming a distinct notch, very 
similar to the antenne of the males of the genus Lampronota, 
but the thick legs, protuberant face, and shortness of the aculeus 
in the female refer it to the Hxochi group of the Tryphons. 
Holmgren’s definition will, however, now require alteration, as 
he separated the genus from Haochus, on account of the first 
joint of the flagellum being transverse in the female, not being 
aware that in the other sex such was not the case. The notch in 
the male antenne is a much better characteristic.— Epwarp

(Brischke describes the male of this species, especially 
referring to the structure of the antenne, in ‘ Schrift. d. naturf. 
Gesell. in Danzig.,’ n.s., vol.iv., part. 111., p. 108 (1878).—E. A. F.]
