170 E. T. Atkinson — Notes on Indian Rliyncliota. [No. 2, 



" Coerulean-blue, immaculate " is the short description given by the 

 earlier writers. Serville describes this species as having the body, feet, 

 and antennae metallic greenish-blue shining ; body above finely punc- 

 tured. Z. illustris, Am. & Serv., differs only in being metallic bine not 

 greenish-blue, like Z. ccerulea. The P. concinna of West wood is described 

 as larger than Z. ccerulea, altogether black with caerulean and purple 

 reflections, antennas and feet black. The P. violacea, Westw., scarcely 

 differs from the preceding, but is altogether more violaceous and some- 

 what punctured. Others give bright blue or blue-green, shining, 

 punctured : legs and antennee, black. Dallas and Stal {I. c. supra) 

 record fully the synonymy and references to figures. Long 9 — 10 mill. 



Reported from all Europe, N. W. Siberia, Japan, China, Bengal, 

 India, Malacca, Java, Borneo, Bujkoti in Jaunsar Bawar, 7,000 feet 

 (mihi). 



Genus Oectrina, Walker. 



Cat. Het. i, p. 118 (1867 j. 



Body very elongate-oval, rather flat : head and pronotum rather 

 largely punctured : head not much shorter than the pronotum, a little 

 narrower in front of the eyes, with a slight ridge which emits two short 

 slight forks on each side bettveen the eyes : eyes very prominent : ros- 

 trum stout, extending to the last coxae : antennae very minutely pubes- 

 cent, about half the length of the body, first joint stout, second shorter 

 than the third, 4 — 5 a little broader and longer than the third : scutum 

 slightly rugulose, not longer than broad, the forepart much contracted : 

 scutellum with a slight ridge, narrowed towards the apex, which is 

 rounded : legs rather stout ; first femora with a spine beneath the apex ; 

 first tibiae much dilated : the elongate hardly convex body, the shape of 

 the head, and the margined pronotum distinguish this genus from Cazira 

 {Walker).
