726 MR. M. JACOBY ON THE [NoV. 3, 



Genus Haltica, Geoff. 

 IIaltica latericosta, sp. nov. 



Metallic blue or green, subopaque ; antennae, tibiae, and tarsi 

 black ; thorax and ehtra scarcely visibly punctured, the latter 

 with a very strongly developed costa from the shoulder to nearly the 

 apex. 



2 . Elytra without lateral costa. 



Length 2-2| lines. 



Head impunctate, the frontal tubercles strongly raised ; carina 

 very short. Antennae nearly as long as the body, the basal joints 

 generally tinged with metallic blue, the rest black, second joint 

 distinctly shorter than the third, this latter shorter than the following 

 joint. Thorax not more than one half broader than long, rather 

 convex, the basal groove deep and slightly sinuate, not extending 

 upwards at the sides, the space in front and behind the groove 

 extremely finely punctured, only visible under a strong lens. Elytra 

 a little more distinctly punctured, the sutural margin sHghtly raised 

 immediately below the base to a short extent ; the lateral costa 

 very stronaly raised, commencing from the shoulder, but abbreviated 

 at a httle distance from the apex, the latter slightly hollowed out, 



Sapporo, on sallow. 



This species bears a great resemblance to H. californica, Mannerh., 

 but is distinguished by the elytral costa not curving round to the 

 suture, and the rather opaque or but little shining and very finely 

 punctured elytra. The female does not differ in any way but by 

 the absence of the costa. The latter in the male is more strongly 

 developed than in any other species with which I am acquainted. 



Haltica obscura, sp. nov. 



Piceous ; basal joints of the autennse and the legs more or less 

 fulvous : thorax distinctly, elytra more closely and strongly punc- 

 tured. 



Length \\ line. 



Head impunctate, the frontal tubercles elongate, bounded behind 

 by a transverse groove ; carina very short and indistii ct ; labrum 

 obscure flavous. Antennae rather robust, thickened at the terminal 

 joints, the third and fourth joints not longer, but thinner than the 

 second, the five terminal joints fuscous, the others flavous. Thorax 

 transversely subquadrate, the sides very nearly straight, the surface 

 impressed near the base with a shallow transverse groove which 

 extends to the sides, the disk distinctly but not very closely punc- 

 tured. Elytra a little widened towards the apices, much more 

 strono-ly and closely punctured than the thorax, the interstices here 

 and there slightly wrinkled. Legs either entirely fulvous or stained 

 with piceous. 



^uvama. 



This species is a little larger than H. picipes, Baly, also from 

 Japan, and may be at once separated by the distinctly punctiired 

 thorax and elytra, which in the other species arc scarcely visibly
