2o2 Mr. 0. (). Waterliouse on ColeoiAera 



has again confused iliem. I have examined Capt. Kerremans' 

 examples, and he has fallen into an error in supposinn;- tlnit 

 lie had both sexes with aeuniinat(! apex to the abdomen. 

 Tlic synonymy as given by Dr. llelJer is quite correct, 

 except that C auromuculata, Saund., is quite distinct from 

 bimaculata, L., and I think C. cyunipennis is also a distinct 

 sjiecics. 



Castalia pulchra, sp. n. 



Somewhat the build of C. bimaculata, L., but relatively 

 shorter and broader, of a beautiful violet-blue. Thorax very 

 broad, strongly punctured, the j)unelures on the disk 

 crowded together, not quite so close at the sides ; tlie sides 

 much rounded, widest near the base, slightly tinted with 

 green. Basal fovea very deep. Elytra much shorter than 

 in C. bimaculata, dark violet-blue, a little paler at the apex, 

 tinted with green at the basal margin; witii an obscure, 

 oblique, reddish-yellow, ill-defined spot behind the middle ; 

 strongly and very densely jiunetured ; each elytron with four 

 wrlUmarked smooth eostie, the first only reaeiiiiig to the 

 middle. The apex denticulate. Lateral carina of tiie thorax 

 (viewed from the side) slightly bisinuous, the surface within 

 this carina not so deeply impressed as in C. hiinaculata. 

 Abdomen dark steel-blue, shining, the segments bordered 

 with violet ; very strongly punctured, the punctures generally 

 separated from each other by less than a diameter of a [junc- 

 ture, but at the sides they arc closer and touch each other. 



Long. 18 mm. 



Hub. Lidia. 



Castalia auromacnlata, Saund. 



The type of this species is a much shorter insect than 

 C. hiniacnlata ; the thorax is shaded with violet on the disk, 

 with golden and copper at the sides. The nnder flanks of 

 thorax and sides of the basal s( gment of the abdomen arc 

 purple-coppery. 'V\\q. abdomen is somewhat golden, with the 

 segments bordered with steel-blue. The elytra are dark 

 green, with the costae somewhat brighter ; the intervals with 

 punctures, which are not very close together and are arranged 

 in lines. 



The type is a female. 



A male example from Capt. Kerrcmans' collection, labelled 

 •' Tonkin, Fairmaire," agrees exactly in form and sculpture 

 with the type; but the colours of the thorax are more 

 obscure and the elytra dark violet.
