2. Elytra with small and exceedingly shallow punc- oe 
tures, shoulders scarcely projectiug ; colour blue 
or greenish-blue H. pusinua, Dujt. 
(v. montana, Duft.) 
H. tamaricis, Schrank. (/ippophaés, Aubé; consobrina, Duft., nee 
All. et Foudr. ; eruce, Steph. Il. 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 searcely 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 intromittent 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. 45-55 mm. 
According to Weise, the species occurs on Hippophaé rhamnoides 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. Iam rather of opinion that all the insects 
standing in our collections under H. consobrina ought to be referred to 
this species. 
H. lythri, Aubé (consobrina, Brit. Cat. (1) ; eruee, 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, antennx 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 alutaceous; legs dark, metallic. 
L, 44-6 mm.
