252 Mr. C. 0. Wateriiouse on Coleoplera 



has again confused ibem. I have examined Capt. Kerreraans' 

 examples, and he has fallen into an error in snpposing that 

 he had both sexes with acuminate apex to the abdomen. 

 The synonymy as given by Dr. Heller is quite correct, 

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

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

 species. 



Castalia pulchra, sp. n. 



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

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

 broad, strongly punctured, the punctures on the disk 

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

 much rounded, widest near the base, slightly tinted with 

 green. Basal fovea very deep. Elytra much shorter than 

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

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

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

 strongly and very densely punctured ; each elytron with four 

 M ell-marked smooth costse, the first only reaching to the 

 middle. The apex denticulate. Lateral carina of the thorax 

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

 this carina not so deeply impressed as in C bimaculata. 

 Abdomen dark steel-blue, shining, the segments bordered 

 with violet ; very strongly punctured, the punctures generally 

 separated from each otlier by less than a diameter of a punc- 

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

Castalia auromaculata, Saund. 



The type of this species is a much shorter insect than 

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

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

 thorax and sides of the basal segment of the abdomen are 

 purple-coppery. The abdomen is somewhat golden, with tlie 

 segments bordered with steel-blue. The elytra are dark 

 green, with the costse 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. Kerremans' collection, lal^elled 

 " 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.
