This little group seems to connect Galeruca and Luperus, and 

 as the three species which it comprises associate remarkably 

 well, I think they ought to be separated from Galeruca, al- 

 though ihey are at present included in that germs by Latreille. 

 The Adimoniaj are distinguished by the shortness and nearly 

 equal length of the 2nd and 3rd joints of the antennae, by a 

 narrower thorax, a triangular scutellum, and a differently 

 formed labrum. 



I shall describe our British species. 



1. A. Alni Linn. F. S. 511.— Marsh. 172. 1.—Panz. 102. 3. 



3^ lines long. Much broader than the following: vio- 

 laceous or deep blue, punctured: antennae and eyes 

 black : head with a small deep fovea in front : thorax 

 short, rather broadest at the base : elytra broad and 

 large, finely and thickly punctured : legs blackish. 

 This Insect is very rare in England, although abundant in 

 Sweden and I believe also in France. It feeds on the leaves 

 of the Alder, and is supposed to have been found in May. 



2. A. halensis Linn. Si/st. Nat. 2. 589. 20.— Marsh. 177. 18. 



— nijjricornis Fab. — Panz. 91. 9. 

 3 lines long. Smooth, shining, ochreous, irregularly 

 punctured: antennae and eyes black; a puncture or 

 short groove in the middle of the face ; the base of the 

 head green: thorax short, with an impression down 

 the middle and a distinct fovea on each side, also a 

 black or violaceous spot on each side beneath : scutel- 

 lum black : elytra bright green, sometimes blue and 

 strongly punctured : tarsi and tips of tibiae blackish. 

 This beautiful insect is sometimes very abundant, and is 

 found upon the furze, grass, &c. in hedges, meadows, and on 

 heaths, from the end of July to the end of October. 



3. A. 4-maculata Linn. — Curtis B. E. pi. 366. — bimaculata 



Panz. 48. 16, but I never saw a specimen with the an- 

 tennae so short. 

 This fine species was I believe first discovered by Miss Hill, 

 near Richmond ; it was afterwards taken by the late Mr. Scales 

 at Halvergate in Norfolk, and I took it in company with Mr. 

 Dale at Whittlesea Mere. It inhabits rushes and other aquatic 

 plants in ditches from the end of June to the middle of July. 



The Plant is Allium ursinum (Ramsons).
