LEMA. 25 



at the middle when seen under a strong lens. Scutellum 

 ferruginous. Elytra with a deep basal depression, the basal 

 portion and the depression impressed with deep round punctures, 

 the latter very fine posteriorly and formed into striae, the 

 interstices convex towards the apex. Body beneath and legs 

 ferruginous. 



Length 9 mm. 



Hob. Assam. Type in Brit. Mus. 



I cannot look upon this species, of which a single specimen only 

 is contained in the Brit. Mus., as a variety of L. lacordairei, Baly 

 (cyanipennis, Lac.) on account of its very much larger size, the 

 impunctuate head, deep elytral depression and impunctate inter- 

 stices as well as their dark violaceous colour. It is also a larger 

 species than the preceding one. 



SECTION IV. 



Thorax with anterior and posterior sulcus, the former sometimes 

 feeble. Coloration as in preceding sections.

Rufous ; antennae black ; anterior portion of head, sides of 

 breast and legs greenish-black ; elytra metallic blue. 



Head with punctured and pubescent elevation between eyes, 

 divided posteriorly by a groove ; antennae slender, extended to 

 middle of elytra. Thorax with anterior angles pointed, im punctate ; 

 surface with anterior medially interrupted and posterior deep 

 sulcus. Elytra with shallow basal depression, strongly punctate- 

 striate, metallic blue or greenish as are the legs and the sides of 

 the breast. <5 . Intermediate tibiae with triangular tooth before 

 apex.

The correct synonymy of this species is not at all understood 

 at present ; the true L. coromandeliana of 1'abricius was described 

 from Coromandel. Since then many other closely allied forms, or 

 it may be varieties, have been united by Baly ; more lately Weise 

 has defined the differences between this and allied species, but 

 neither he nor Baly, so far as I am aware, had specimens before 

 them from Coromandel, and it remains to be seen whether the 

 Malayan insects with dentate tibiae in the male or those from 

 Ceylon with or without similar structure are all one species. At 

 present Lacordaire's description (he was the first to give a detailed 

 one of L. coromandeliana) must be accepted, since he received the
