Castalla Fairmairei, sp. n. 



Very similar to C. auroinaculata, but more elonjrato. 

 Bluish green, with slight brassy tint. Thorax convex, 

 densely punctured as in uuromaculata, the punctures at the 

 sides very slightly separated. The sides rather strongly 

 rounded. The disk tinted with blue; the sides with brassy. 

 Elytra rather strongly, closely, and irregularly punctured, 

 the punctures not forming lines. Body beneath brassy, the 

 under flanks of the thorax and b;'.se of abdomen tinted with 

 coppery. 



Long. 21 mm. 



Hdb. Tonkin {coll. Kerremans, ex Fainnaire). 



1 have been iji niueh doul)t as to this insect being distinct 

 from C. auronKiculatn. There were four examples in Capt. 

 Kerremans^ collection, all labelled " Tonkin, Fairmaire," 

 one male and three females. The male differs from the 

 females in being shorten* ; it has tlie thorax ahnost parallel 

 at the sides behind the middle. The elytra are compara- 

 tively sparingly punctured and the punctures are in lines. 

 In these respects it agrees exactly with the type of auro- 

 maculata. The fenuJes, to which I have now given the 

 name C. Fairmairei, are much longer, have the sides of the 

 thorax strongly rounded and the elytra densely and irregu- 

 hirly punctured. 



1 at first thought that these differences might be sexual, 

 but the dissection of the type of auromaculuta proved it 

 unquestionably to be a female. Under these circumstances 

 1 have placed the male from Tonkin Avith auromaculuta.. ami 

 regard the three females from Tonkin as those of a distinct 

 species. 



Castalia Bettuni, sp n. 



General form of C. bimaculata, L., but a little broader. 

 Head, thorax, and body beneath .tnieous ; elytra obscure 

 violet, with an indistinct ferruginous spot near the side 

 before the middle. Thorax very broad, moderately strongly 

 })uuctured, the punctures more sharply defined than iu 

 bimaculata, separated from each other on the disk by about 

 the diameter of a puncture, a little closer together at the 

 posterior angles ; at the front angles (where the surface is 

 slightly impressed and brassy) the punctures are finer and 

 crowded together. The disk has an impressed Y-shaped 

 mark. The punctuation of the elytra is very distinct. In 

 the intervals between the costse the punctures are generally 

 slightly separated from each other, but at the apex and sides 

 they arc more crowded together. [The specimen described
