214 Mr. G. R. Waterhouse's Notes 



h. Third joint of antennae short, but little longer than the 

 second. 



6. Entirely golden-green above. — D. sagittarice. 



Fab., Gyll., Steph., Lacord. 



My specimens were taken at Covehithe, in 

 Suffolk, by Mr. Brewer, in June. 



7. Rather more convex than the two preceding 



species ; dullish aeneous, with a longitudinal 

 cupreous band close within the lateral margin of 

 each elytron, and, generally, a short longitudinal 

 band within this at the base. — D. Lemnce, Fab., 

 Gyll., Steph., Lacord. 



I have recently taken specimens in the Plum- 

 stead marches. July. 



8. Elongate and narrow (resembling D. linearis); 



usually of a dullish frosted aeneous ; posterior 

 femora with an acute tooth ; thorax rugosely 

 punctured ; elytra with two oblong depressions 

 on basal half. — D. Thalassiua, Germ., Gyll., 

 Lacord. Stephens' Illustrations, iv. 272, 11, 

 but not of Stephens' Collection. The insect 

 which there stands under the name " Thalassina" 

 is D. Sparganii. 



There are also other specimens o^D. Thalassina 

 in the cabinet alluded to, standing under the 

 name D. obscura. The description of D. obscura 

 in the " Illustrations," however, is taken from 

 Gyllenhal. 



My specimens are chiefly from Reigate, being 

 given to me by Mr. Linnell. 



9. Less elongate than the preceding, less frosted or 



dull, being a little glossy ; the colour usually 

 rather inclining to cupreous or cupro-aeneous ; 

 the punctures of the thorax rather finer, but 

 better defined, being less rugulose ; elytra less 

 strongly punctate-striate, and with four oblong 

 depressions (the hinder pair in D. Thalassina 

 are almost always very obsolete) ; posterior 

 femora obscurely dentate. — D. impressa, Payk., 

 Gyll., Lacord. Stephens' Illustr. iv. 272, 12, 

 but not of his Collection, where D. impressa is 

 represented by a series of specimens of D. 

 Thalassina, and one specimen of D. simplex.
