Dark metallic blue ; antennae black, the upper part of the head, 

 the thorax and the abdomen fulvous ; elytra metallic blue, the sides 

 with a fulvous longitudinal band. 



Head not constricted posteriorly, impunctate, the vertex fulvous, 

 the lower portion and the space surrounding the eyes bluish- 

 black, the latter deeply notched ; antennae black, not extended 

 to half the length oL' the elytra, the terminal joints gradually 

 widened. Thorax subquadrate, fulvous, sides only moderately 

 constricted in the middle, the basal sulcus deep and placed nearly 

 at the middle, the surface nearly impunctate. Scutellum piceous. 

 Elytra meiallic blue, without basal depression, with deep punctures, 

 the latter gradually diminishing in size posteriorly, the inter- 

 stices slightly convex at the apex ; the sides with a fulvous band 

 that commences at the shoulders, is strongly widened at the 

 middle and abbreviated at the apex. Breast and legs bluish-black, 

 abdomen fulvous. 



Length 5 mm. 



Hcib. India. 



This may be only a variety of L. semifulva, Jac., in which the 

 amount of fulvous colour of the elytra is larger and black substi- 

 tuted for blue.

 Caarulean blue; elytra with marginal bands at middle and 



apex rufo-flavous ; underside rufo-fuscous ; legs flavous ; antennae

Elytra parallel and robust; the head rugose anteriorly, transversely 

 foveolate between the eyes, smooth behind the latter. Thorax as 

 long as broad, the anterior angles moderately rounded, the sides 

 deeply constricted, the basal sulcus distinct, the surface sparingly 

 punctured. Elytra caerulean blue, with a short basal fovea, strongly 

 punctured, the interstices convex near the apex ; the lateral 

 band constricted between the second and sixth rows below the 

 shoulders, terminates posteriorly between the fourth and fifth 

 rows. 



Length 4 mm. 



Sab. Northern India. 



This species is comparatively easy to discriminate on account 

 of the metallic blue upper surface and the markings of the 

 elytra.

Greenish-black beneath ; head and thorax fulvous ; labrum and
