Chaetocnema puncticollis, Motschulsky.

Another Indian species more related to our [European] Tlan. 

 concinna, Marsh., is my Tlan. puncticollis. It resembles the first- 

 named in form and shape, but its pronotum is more rectangular, 

 more transverse, scarcely narrowed towards the head ; the last- 

 named character accentuates the anterior lateral angles of the 

 prothorax ; the pronotal punctuation is stronger and closer, while 

 the punctures on the elytral striae, on the contrary, are somewhat- 

 finer.

Chsetocnema gracilis, Motschulshj. 



Tlanoma gracilis, Motsch., Etud. Ent. vii, 1858, p. 107. 



A third species from the same country [India] is one-half 

 smaller, with the prothorax rectangular but more appreciably 

 produced towards the scutellum ; the anterior lateral angles of the 

 prothorax are prominently extended, the sides more rounded. 

 The humeral angles of the elytra are more rounded than in the 

 preceding species.

Genotype, CJirysomeJa lutea, Oliv., 1790 (Galleruca grandis, 

 Orondal, 1808). 



Insects usually of large and massive build, broad, oblong; the 

 largest representatives of this group from our regions. Bead as 

 broad as the deep emargination of the front margin of the pro- 

 thorax, vertex not very convex, often more or less flat; surface 

 generally very uneven, with a deep rounded impression on either side 

 above the eye and continuing round the base of the antenna, 

 these two impressions producing a longitudinal elevation in the 

 interantennal space; labrum short, broader than long ; maxillary 

 palpi somewhat large, second and third segments more or less 

 conical, fourth oval and a little shorter than the preceding seg- 

 ment ; eyes convex, very often their bases seem raised owing to 

 the depression round them. Antenme short, only extending to 

 the humerus of the elytra and, relative to the massive build of 

 the insect, slender; the four basal segments always different 

 from the next seven, which are somewhat thicker, opaque and 

 pubescent, and generally more or less nearly equal. Protliorax 

 broader than long, anterior margin deeply emarginate, posterior
