 FROM SUMATRA 



C. RITSEMA Cz. 



During my recent visit to Paris Mr. Ant. Grouvelle has 

 had the courtesy to offer me from his collection a unique 

 specimen of a very interesting new species of the genus 

 Helota. This specimen, a female, was captured by Mr. 

 Bouchard , one of his correspondents , in the mountainous 

 regions of Palembang (Sumatra). At the request of Mr. 

 Grouvelle I dedicate this species to its fortunate discov- 

 erer, calling it 



Helota Bouchardi. 



It is closely allied to Helota immaculata Rits. ^), from 

 Burma, having likewise the elytra immaculate, but it 

 differs by the finer punctuation , blue colour of the elytra 

 without lateral coppery streak , and pale coloured apical 

 half of the tibiae which are moreover shorter and thicker 

 in the new species ; finally , the anterior tibiae are less 

 strongly curved in the female of Bouchardi. 



Length 7,5 mm. — Shining; upper surface of the head 

 bright metallic green , the antennae dark pitchy , paler 

 at the base, the first joint with a metallic green spot at 

 the tip in front; the pronotum at the sides pale testace-
