14 Mr. J. Walton on the genera 



have also mixed the two species ; the former has figured Cure, 

 micans and described the " thighs dent at ed\" — the latter refers to 

 Donovan and has copied the description of Linnseus. Stephens, 

 in his ' Syst. Catal./ refers Cure, Pyri of Donovan and Marsham 

 to Cure, micans ; but Kirby in his manuscript, although he also 

 refers it to the same species, has placed a note of doubt — '^ an 

 Marshami t" Cure, amaurus of Marsham, according to a speci- 

 men in the Kirbian collection, and which agrees with Marsham's 

 description, is certainly a variety of this insect with silvery-gray 

 scales, and the apical half of the femora black. 



Abundant on oaks and other trees in or near woods, and some- 

 times amongst grass in June. 



4. Phyllobius argentatus of authors. 

 Cure, argentatus, Linn., Mus. Linn. 

 P.flavidus etfemoralis, Kirb. MSS. 



This insect, although very liable to be confounded with the 

 following, is readily distinguished from it, by having the eyes 

 less prominent, the rostrum shorter, the antennae entirely rufous 

 or testaceous, with the basal joints of the funiculus unequal, the 

 second joint being distinctly more slender and longer than the 

 first ; the legs rufous or testaceous, the femora sometimes piceous 

 or black : the form of the thorax varies considerably in this and 

 the succeeding species from subcylindrical to subglobose, mth 

 intervening forms, and the femora of some individuals are more 

 robust — hence the name femoralis of Kirby ; these however are 

 only regarded as sexual disparities, and are all referred to this in- 

 constant species. 



Abundant throughout the country from May to August. 



5. P. maeulieornisj Germ., Gyll., Steph., Schonh. 



— nigripes et angustior, Kirb. MSS. 



This differs from P. argentatus in having the head depressed 

 in front, the eyes distinctly more prominent ; the rostrum longer 

 and dilated at the apex, elevated and deeply furrowed above ; the 

 antennse testaceous, with the apex of the scape piceous and the 

 clava fuscous, the basal joints of the funiculus of equal length ; 

 the legs black ; the tibife and tarsi sometimes obscure testaceous. 



Rather rare in the south of England ; I have found it in mea- 

 dows at Mickleham and at Birch Wood in June, and abundantly 

 in Yorkshire amongst grass on the magnesian limestone. 



6. P. oblongus of authors. 



Cure, oblongus, Linn., Mus. Linn. 



— rufescens, Marsh., Kirb. MSS. 



— testaceus, Kirb. MSS. 

 Nemoieus oblongus, Steph. 



Some examples of this insect have the head and thorax en- 

 tirely black, and others rufo-ferruginous.
