356 PHVTOPHAOA. [Haltica. 



1. Elytra with ruthcr \nrgc but shallow puncture*, 

 shoulders rather strongly projecting ; colour dark 



blue H. PAL08TRI8, Weise. 



2. Elytra with small and exceedingly shallow punc- 

 tures, shoulders scarcely projecting ; colour blue 



or greenish-blue H. PUSILLA, Duft. 



(v. moniana, Duft.) 



B. tamaricia, Schrank. (liippophaes, Aube*; consolrina, Duft., we 

 All. et Foudr. ; erucce, Steph. 111. iv. 307, teste Weise). Subelongate, 

 convex, cyaneous, rarely greenish-cyaneous, upper surface alutaceous and 

 finely and often somewhat obsoletely punctured, rather dull, with a 

 silky sheen ; frontal tubercles elongate ; thorax small, convex, scarcely 

 narrowed in front, with the sides scarcely rounded and comparatively 

 broadly margined, the anterior angles not or scarcely callose, and with a 

 deep transverse furrow before base ; elytra much broader than base of 

 thorax, somewhat produced and rounded at apex, shoulders marked ; 

 Weise compares the species with H. lythri, but .says that it is more 

 slender than that species, and easily distinguished from it by the narrow 

 frontal tubercles, the smaller and proportionally more broadly margined 

 thorax, of which the transverse basal furrow is deeper, and the finely 

 and obsoletely punctured elytra, of which the shoulders project rather 

 widely beyond the base of the thorax ; the male intromitteut organ 

 appears to be shaped much as in H. pusilla, forming at the apex a 

 broad triangular point, and in this sex the last abdominal segment is 

 smooth in the middle and slightly impressed at base and apex, or else 

 has a shallow central furrow. L. 4|-5i mm. 



According to Wei&e, the species occurs on Hippophae rliamnoides and 

 Myricaria germanica ; he records it from England, and there are speci- 

 mens in Dr. Power's collection which I had referred to the species before 

 I obtained Herr Reitter's confirmation of its identity ; they are from 

 Mr. Crotch without locality. I am rather of opinion that all the insects 

 standing in our collections under H. consobrina ought to be referred to 

 this species. 



B. lythri, Aube (mnsobrina, Brit. Cat. (?) ; eruca, Duft. ; indigacea, 

 Steph.). Elongate oblong-oval, narrow in front and gradually and 

 regularly widened until behind middle, broadly rounded behind in the 

 female and gradually contracted and slightly produced in the male, of a 

 deep blue or violaceous colour, elytra depressed, very finely but closely 

 and distinctly alutaceous, comparatively dull ; head scarcely punctured, 

 with an impression on vertex and strong frontal tubercles, antennae stout, 

 dark, third joint a little longer than second ; thorax about half as broad 

 again as long, slightly rounded before middle, and narrowed in front, 

 anterior angles projecting, slightly callose, obsoletely punctured and 

 almost smooth on disc, more plainly punctured towards anterior angles ; 

 elytra only a little broader at base than thorax, with feeble humeral 

 callosities, and fine and close punctuation, which is made up of larger 

 and smaller punctures, interstices alutnccous ; legs dark, metallic. 

 L, 4A-6 mm.
