but that this is merely another large form of L. praiensis, and his 

 inconsistency in the statement of its size has been noted by Fowler. 

 We have not seen the specimens named by Allard for the late 

 Mr. Wollaston on which its claim to a place in the British lists 

 apparently rests, but one of us has recently examined an example 

 sent by Crotch to Mr. G-orham as medicaginis, and Mr. Gorhani 

 concurs with us in considering it to be pratensis. Nor is there 

 anything else that we have seen in British collections, supposed to 

 be this form, which can be said to possess even varietal value in 

 a genus like Longitarsiis, and we consider therefore that we are 

 justified in adopting the same course with it as with L. reichei.

Syns. — Icevis, All. [Mon. p. 351 ; Brit. Colls, (riec. Duft., teste 

 Bedel) aemginosus, Brit. Colls. 



In shape a rounded oval, convex, aciuninate in S , with legs and antenna3 

 longer in proportion to its size than in other mem1)ers of the section, uni- 

 colorous pale testaceoiis. Head ferruginous, almost smooth between eyes. 

 Antennae : very long, testaceous, with the last four or five joints slightly dusky 

 at apices. Thorax ; transverse, bordered, very variable in sculpture, pimctua- 

 tion sometimes fairly distinct or very weakly rugose, sometimes quite obsolete, 

 never strong. Elytra : concolorous with thorax, sometimes with faint indica- 

 tions of darker lineation, punctuation always very feeble and confused, sutu.re 

 sometimes very faintly reddish, apices slightly separately rounded — in fresh 

 specimens the outer edges of the elytra at apex bear a few long white cilia. 

 Legs : testaceous, posterior femora sometimes brownish on the upper surface ; 

 posterior tibial spurs short; first joint of anterior tarsi in $ not enlarged. 

 Underside ferruginous. Apterous (2). Length l^^-lf mm. 



This species can be distinguished from L. pratensis by its larger 

 average size and more uniform coloration ; from L. gracilis by its 

 more oval shape ; from L. pellucidus by its much weaker elytral 

 punctuation ; and from them all by its much longer antennae, which 

 bear only faint traces of the apical infuscation common to all our 

 other species of Longitarsus except L. ruhiginosus. 



Food plants. — L. snccineus appears to be attached to various 

 species of the order Compositse. Allard says it is coimnon on 

 Chrysanthemums in gardens, and this statement we are able to con- 

 firm from our own experience in Cheshire. 



Mr. P. de la Garde has taken the species in abundance on 

 C. leucanthemum in Devonshire, and Mr. H. C. Dollman on Achillea

(2) Weisc mentions a variety, luctator, which ajipears to be a winged form, but we have no 

 record of it from tliis country, although it probably occurs hero.
