31 G KHTNCHOPHORA. [Anthonomus. 



with the head and rostrum, and sometimes margins of 



elytra, black A. VARIAN3, Payk. 



ii. Rostrum dull ; anterior femora with a feeble tooth. 



1. Colour ferruginous ; rostrum short (A. britannus, Desbr.) 



2. Colour black ; rostrum long. 



A. Thorax with the sides strongly narrowed ill 

 front ; first joint of funic;ulus of antennae much 



longer than broad ; size larger A. RFBI, Herbst. 



B. Thorax with the sides very slightly narrowed in 

 front, almost subpantllel ; first joint of funiculus 

 of antennae not much longer than broad; size 



smaller A. COMAEI, Crotch. 



A. ulmi, De G. Brownish-red, or red, clothed with scanty whitish 

 pubescence ; head, rostrum and breast pitchy-black or ferruginous ; 

 rostrum long, slightly curved, dull, of equal length in both sexes ; 

 antennas reddish-testaceous, darker towards apex, inserted further from 

 apex than in A. pedicularius ; thorax closely and rather strongly punc- 

 tured ; scutellum elongate -oval, thickly pubescent; elytra diffusely 

 covered with pale hairs, with a slender band in the middle, and a straight 

 transverse fascia of whitish pubescence (also oil scutellum) behind middle, 

 with finely punctured striae and closely sculptured interstices ; legs 

 reddish or ferruginous, femora more or less dark, anterior pair with a 

 very strong tooth, posterior pairs feebly toothed ; basal half of the tibiae 

 strongly sinuate on interior margin. L. 3-4 mm. 



Male with the antennae inserted further in front of middle of rostrum 

 than in female. 



On elms, &c. ; not uncommon in many localities in the London and southern 

 districts and the Midlands ; less common further north ; Manchester district ; 

 Northumberland and Durham district; Scotland rare, Solway, Forth, Moray and 

 probably other districts ; Ireland, near Dublin and Belfast. 



The colour of this species is very variable, and the points of difference 

 which have usually been given as separating it from the following are 

 sometimes hard to make out satisfactorily ; as a rule the very large 

 teeth of the anterior femora afford a decisive character, but in some 

 specimens of A. pedicularius the teeth are very much developed, and 

 some of the other distinctions are more or less comparative ; the insect, 

 however, may at once be known from the latter species by the strongly 

 sinuate anterior tibiae and the longer and more slender rostrum, which 

 has the antennae inserted further from the apex. Bedel appears to class 

 A. ulmi and A. pedicularius as synonymous, but I cannot think that he 

 is right in so doing. Mr. Walton says he has found A. ulmi plentifully 

 on elms, but never in company with A. pedicularius ; the latter insect 

 appears to occur almost entirely on Cratcegus. 



A. Rosinee, Des Grozis. Oval, rather convex, of the form of A. ulmi 

 and with the sculpture of A. Chevrolati; size small; colour varying 

 from reddish-brown to ferruginous ; rostrum almost or entirely black ; 

 antennae and legs ferruginous, femora usually dark in the middle ;
