Castalla Fainnairei, sp. n. 



Very similar to C. uuruniaru/uta, but more elongate. 

 Bluish green, with sliglit brassy tint. Thorax convex, 

 densely punctured as in uuromacalatu, the punctures at the 

 sides very slif^htly separated. The sides rather stronj^ly 

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

 Elytra rather strongly, closely, and irregularly punctured, 

 the i)unctures not i'oruiing liiu's. Body btnieath brassy, the 

 under Hanks of the thorax and b;vse of abdomen tinted with 

 coppery. 



Long. 21 mm. 



Hah. Tonkin {coll. Kerremana, ex Fairmaire). 



1 have been in much floubt as to this insect being distinct 

 from C auromnculatd. 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 shorter ; it has the thorax almost parallel 

 at the sides behind the middle. The elytra are comi)ara- 

 tively sparingly punctured, and the ])uneturcs are in lines. 

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

 maculuta. The females, 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- 

 larly punctured. 



1 at first thought that these diflPerences might be sexual, 

 but the dissection of the type of auromaculnta proved it 

 unquestionably to be a female. Under these circumstances 

 I have placed the male from Tonkin with auromaculata, aiul 

 regard the three females from Tonkin as those of a distinct 

 species. 



Castalia Bettoni, sp n. 



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

 Head, thorax, and body beneath leneous ; elytra obscure 

 violet, with an indistinct ferruginous spot near the side 

 before the middle. Thorax very broad, moderately strongly 

 punctured, the punctures more sharply defined than in 

 himaculuta, separated fnnn each other on the disk by about 

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

 posteiior 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
