194 CUKCULIONID^. 



Mickleham (Champion) ; Shiere (most probably this was the locaUty) 

 (Capron); Box Hill (W. West) on EcJiium vulgare : and Mickleham 

 (Billings). It appears, however, to be doubtful whether we have not 

 two or more species under the name micros. Mr. E. A. Butler, who 

 captured two of the uncertain examples at Tintagel, Cornwall, goes 

 fully into the question (Ent. Mo. Mag. xlv. (2 Ser. xx.) VM)\), 99), but 

 the matter is by no means settled ; the Tintagel specimens have the 

 pubescence raised, whereas in the true M. micros it is depressed ; the 

 specimens refei^ed to (Brit. Col. v. 307) as taken by Wollaston at 

 Whitsand Bay, one of which is in the Cambridge Museum, appear to 

 be different from either Champion's or Butler's. 



Mr. Butler gives the following table for separating the species : it 

 differs from mine {I.e. p. 30G) in that no account is taken of the 

 cliaracter of the single or double rows of pubescence between the strife, 

 which appears not to be always a constant character. 



A. Posterior femora toothed. 



i. Form short and broad ; pubescence 



coarse and raised . . . M. graminis, GyU. 



ii. Form narrower and more elongate ; 



pubescence less coarse . . . M. plantarum, Germ. 



B, Posterior femora not toothed. 



i. Size larger ; pubescence very short ; 

 last segment of male deeply ex- 

 cavate, and with a strong tooth 



on each side . . . . M. campanul.e, L. 



ii. Size smaller ; pubescence longer ;

ANTHONOMUS, Germar. 



A. rufus, Schon. (Gen. Cure. iii. p. 347). Des Logos (Ann. Soc. 

 Ent, Fr. viii. 1894, p, 43(;). This species belongs to the ulmi-pedicularius 

 group, which has caused mvich trouble both to authors and collectors, 

 and which can hardly yet be regarded as finally settled. From A. tdmi, 

 De G., and A. chevrolati, Desb., it may be known by its comparatively 

 simple anterior tibije ; in the last-named species these are very deeply 

 sinuate on their interior margin towards the base : from A. 2)edicularius, 

 L., it is easily separated by the fact that the posterior tibias are without 

 teeth. The variety A. rosince, Des Gozis, apart from other diflerences, 

 is a much smaller insect. L. 3-3| mm. 



Introduced as British by Mr. Donisthorpe (Ent. Record, lOOO, 

 p. 159). Fairlight, near Hastings, on blackthorn (Bennett) ; also 

 taken in the same locality some years afterwards, hibernating under 

 the bark of old ivy, by Mr. Bennett, and Professor Beare {v. Ent. 

 Record, xii. 159). 



There has been considerable confusion with regard to this genus, 

 and one or two points still want further working out.
