The pale head is different from that found in A^. oberthiiri Baly and

Figure 12 



About 7 mm. in length, elongate oblong oval, alutaceous, not very- 

 shiny, the elytra faintly costate, pale yellowish brown, the head with 

 a median occipital piceous spot and also a piceous area about the eyes, 

 the elytra with a violaceous or greenish mark running across the base 

 and down the side to the apical curve and another vitta a little way 

 down the suture, two median spots, one before and the other after 

 the middle on each elytron, antennae with the intermediate joints 

 dark, breast dark. 



Head with the interocular space half width of head, occiput finely 

 punctate, a depression over the frontal tubercles, carina well developed, 

 pale with a piceous spot at base of the occiput and a dark area about 

 the back of the eyes, mouthparts more or less piceous. Antennae

 yellowish brown, finely punctate. Scutellum pale. Elytra faintly 

 costate along the sides, finely and rather sparsely punctate, alutaceous, 

 not very shiny, pale yellowish brown with violaceous or greenish 

 markings along the base and side down to the apical curve and also 

 about the scutellum down the sutm'e, a median spot before and another 

 one after the middle, and the lateral darkening opposite each wider, 

 as if possibly in darker specimens to connect with the median spot. 

 Body beneath pale with the breast dark; legs pale with the tibiae and 

 tarsi a little deeper in coloring on the outside. Length 7 mm.; 

 \vidth 3.3 mm. 



Type, female; one paratype, female; both in BMNH, Baly collec-

Remarks: The occipital dark spot is unusual in the genus and 

 besides this species is found only in Neobrotica oblongopunctata Jacoby 

 and A^. ebraea (Fabricius). This species has somewhat the same 

 elytral pattern as A^. duodecimsignata but in that species there is no 

 metallic lustre and the legs are pale.
