214 THE ENTOMOLOGIST. 



red. Common. The long recurved hook on the third joint 

 of the antennae in the male will distinguish this from two 

 other allied species, having nearly the same colouring, which 

 both occur in Germanw 



2. 71/. hipHstulatus,^.—^^ lines. Green ; mouth yellow; 

 thorax with the anterior angles and the apex of the elytra 

 red. Common. The singular appendages to the iDasal joints 

 of the male antennae leave this species quite unmistakable. 



3. M. viridis, F. — 2 lines. Like the preceding, but the 

 elytra are very narrowly margined with red at the apex, and 

 the thorax is concolorous ; occasionally, the elytra are also 

 concolorous. Not rare, and scattered over all N. Europe. 



§ II. Elytra in the male with the apex produced, and with 

 styliform appendages. 



4. M. marginellus, 01. — 2|- lines. Green ; margins of the 

 thorax and apex of the elytra red. A coast species, belong- 

 ing to Central Europe, and not found in Sweden. 



5. M. spinosus, Er. — 2^ lines. Green ; elytra red at the 

 apex ; antennae in the male simple. I believe a specimen 

 exists in Mr. Walerhouse's collection. It is very common 



- in S. Europe, and extends some distance into Germany. 



Numerous southern species exist of this genus, whose num- 

 ber yearly augments, and it is not impossible that Cornwall 

 or Ireland may yet produce some novelties. 



AxiNOTARSUS, Motsch.- 



A genus founded by Motschulsky to include the small 

 Malachii, in which the male anterior tarsi have the second 

 joint produced beneath. It has been since adopted by 

 Kiesenwetter and Thomson. 



1. A. ptillcorius, Fah.—l^ Wne. Dark green; sides of the 

 thorax and apex of the elytra red ; antennae and anterior 

 tarsi testaceous. Not rare. A. marginalis. Lop., which is 

 found in Germany, closely resembles this, but has the ante- 

 rior tibiae also pale. 



2. A. riijicollis, 01. 1790, Ksw. Rubricollis, Ms/i.— Dark 

 green ; thorax and apex of elytra red. Tolerably common. 

 This is the true ruficullis, OL, as his figure at- once shows. 

 Fabricius, as usual, applied the name to another species.
