middle of the first longitudinal (E.^), or very slightly beyond it, and in very 

 rare instances the base of the upper branch of the media is defective ; in the 

 male the media is invariably simple, and Rs always touches the apex of R ' ; the 

 cubitus may be entirely simple or may have the lower branch more or less 

 present, but never complete. The antennae in the female are slightly shorter, 

 in the male a little longer, than the head and thorax together.

Note on the Clirysomela sanguinolenta and marginalis of British collections. — 

 My friend Dr. Bergroth has just called my attention to a paper by Mr. Tor 

 Helliesen on Chrysomela sanguinolenta, L., and its allies, written in Esperanto 

 and published in the " Aarshefte" of the Stavanger Museum for 1911 (issued 

 in 1912), pp. 1-16, pis. i-iii. This paper affects the names or synonymy of our 

 two British forms, and an extract from it will interest Coleopterists. The four 

 species recognised are : 1, sanguinolenta, L., Thoms. (nee Kiister, Weise) ; 

 2, gypsophilae, Kiist. (with vars gaubili, Luc, and lucidicollis, Kiist.) ; 3, kiisteri, 

 n.n. {= sanguinolenta, Kiist., Weise) ; 4, crassicornis, n. sp. No. 1 is the insect 

 known to us under the name marginalis, Dvxft. (distinguenda, Steph.) ; Nos. 2, 

 3 do not, I believe, occur in Britain ; No. 4, crassicorriis, is the C. sanguinolenta
