CIIEYSOMELITSTiE. 



Ch. eoeruleans, Scriba, var. angelica, Reiche ; and in his catalogue 

 (Junk and Schenkling, Berlin, part 68, 1916, p. 147) lie has 

 recorded bella Jacoby and angelica Baly (nec Reiche) as synonyms 

 of Synerga modesta (Fabr.). I have not seen Synerga modesta 

 (Eabr.), and as I cannot find the above characters of the genus 

 Synerga in the Himalayan specimens of bella which are before me, 

 I have retained bella in the genus Chrysolina, and give here a 

 translation of Weise's remarks. I do not know if Weise saw 

 Jacoby's type of bella, which is in the British Museum.

Body oblong, moderately convex. Colour deep metallic steel- 

 blue or violet; in many specimens the colour of the upper side is 

 mixed with cupreous sheen, the terminal portions of each of the 

 basal segments of the antennae and those of the ventral plates of 

 the abdomen being edged with brown. 



Head closely punctate, Y-shaped mark feebly impressed. 

 Anten na3 passing beyond the pronotum to a certain extent, 

 moderately stout, the six or seven basal segments shining, the 

 apical four or live pubescent and more incrassate, the third 

 segment hardly longer than the fourth, the second nearly half 

 the length of the lliird. Prothorax almost twice as broad as long, 

 sides rounded and narrowed anteriorly, anterior angles acute but 

 rounded, upper surface closely punctate, each side having a 

 longitudinal convex area which is separated from the disc by a band 

 of coarse and confluent punctures, the surface of the convex area 

 being also closely punctate. Seutelium ovate, smooth, impunctate. 

 Elytra broader at the base than the prothorax, with sides more or 

 less parallel, broadly rounded towards the apex, upper surface 

 very closely and irregularly punctate; each elytron has five 

 longitudinal and parallel rows of smooth, shiny, impunctate round 

 spots ; these latter are not of equal size, some being larger than 

 others; the row along the suture terminates at about the middle, 

 all the rows are more or less convergent on the apical area, and
